Depending on the length of the instruction period, the background of students, and your interests, you may select subsets of chapters to teach in various sequential order- ings. For example, if you would like to give only a short introduction to students on data mining, you may follow the suggested sequence in Figure P.1. Notice that depending on the need, you can also omit some sections or subsections in a chapter if desired. Depending on the length of the course and its technical scope, you may choose to selectively add more chapters to this preliminary sequence. For example, instructors who are more interested in advanced classiﬁcation methods may ﬁrst add “Chapter 9. Classiﬁcation: Advanced Methods”; those more interested in pattern mining may choose to include “Chapter 7. Advanced Pattern Mining”; whereas those interested in OLAP and data cube technology may like to add “Chapter 4. Data Warehousing and Online Analytical Processing” and “Chapter 5. Data Cube Technology.” Alternatively, you may choose to teach the whole book in a two-course sequence that covers all of the chapters in the book, plus, when time permits, some advanced topics such as graph and network mining. Material for such advanced topics may be selected from the companion chapters available from the book’s web site, accompanied with a set of selected research papers. Individual chapters in this book can also be used for tutorials or for special topics in related courses, such as machine learning, pattern recognition, data warehousing, and intelligent data analysis. Each chapter ends with a set of exercises, suitable as assigned homework. The exer- cises are either short questions that test basic mastery of the material covered, longer questions that require analytical thinking, or implementation projects. Some exercises can also be used as research discussion topics. The bibliographic notes at the end of each chapter can be used to ﬁnd the research literature that contains the origin of the concepts and methods presented, in-depth treatment of related topics, and possible extensions. T o the Student We hope that this textbook will spark your interest in the young yet fast-evolving ﬁeld of data mining. We have attempted to present the material in a clear manner, with careful explanation of the topics covered. Each chapter ends with a summary describing the main points. We have included many ﬁgures and illustrations throughout the text to make the book more enjoyable and reader-friendly. Although this book was designed as a textbook, we have tried to organize it so that it will also be useful to you as a reference #################### File:

of this book. While we believe many parts of the IOI syllabus have been included in this book – which should give you a respectable score in future IOIs – we are well aware that modern IOI tasks requires more problem solving skills and creativity that we cannot teach via this book. So, keep practicing! Speciﬁc to the Teachers/Coaches This book is used in Steven’s CS3233 - ‘Competitive Programming’ course in the School of Com- puting, National University of Singapore. It is conducted in 13 teaching weeks using the following lesson plan (see Table 2). The PDF slides (only the public version) are given in the companion web site of this book. Hints/brief solutions of the written exercises in this book are given in Appendix A. Fellow teachers/coaches are free to modify the lesson plan to suit your students’ needs.

There are many written exercises and programming problems (≈1198) scattered throughout the body text of this book which can be skipped at ﬁrst if the solution is not known at that point of time, but can be revisited later after the reader has accumulated new knowledge to solve it. Solving these exercises will strengthen the concepts taught in this book as they usually contain interesting twists or variants of the topic being discussed. Make sure to attempt them once. We believe this book is and will be relevant to many university and high school students as ICPC and IOI will be around for many years ahead. New students will require the ‘basic’ knowledge presented in this book before hunting for more challenges after mastering this book. But before you assume anything, please check this book’s table of contents to see what we mean by ‘basic’. vii #################### File: Competitive%20Programming%2C%202nd%20Edition%20-%20Steven%20Halim%20%28PDF%29.pdf Page: 168 Context: 6.2. BASIC STRING PROCESSING SKILLS c ⃝Steven & Felix (a) Do you know how to store a string in your favorite programming language? (b) How to read a given text input line by line? (c) How to concatenate (combine) two strings into a larger one? (d) How to check if a line starts with string ‘.......’ to stop reading input? I love CS3233 Competitive Programming. i also love AlGoRiThM .......you must stop after reading this line as it starts with 7 dots after the first input block, there will be one looooooooooooooooong line... 2. Suppose we have one long string T. We want to check if another string P can be found in T. Report all the indices where P appears in T or report -1 if P cannot be found in T. For example, if str = ‘‘I love CS3233 Competitive Programming. i also love AlGoRiThM’’ and P = ‘I’, then the output is only {0} (0-based indexing). If uppercase ‘I’ and lowercase ‘i’ are considered diﬀerent, then the character ‘i’ at index {39} is not part of the output. If P = ‘love’, then the output is {2, 46}. If P = ‘book’, then the output is {-1}. (a) How to ﬁnd the ﬁrst occurrence of a substring in a string (if any)? Do we need to implement a string matching algorithm (like Knuth-Morris-Pratt (KMP) algorithm discussed in Section 6.4, etc) or can we just use library functions? (b) How to ﬁnd the next occurrence(s) of a substring in a string (if any)? 3. Suppose we want to do some simple analysis of the characters in T and also to transform each character in T into lowercase. The required analysis are: How many digits, vowels [aeiouAEIOU], and consonants (other lower/uppercase alphabets that are not vowels) are there in T? Can you do all these in O(n) where n is the length of the string T? 4. Next, we want to break this one long string T into tokens (substrings) and store them into an array of strings called tokens. For this mini task, the delimiters of these tokens are spaces and periods (thus breaking sentences into words). For example, if we tokenize the string T (already in lowercase form), we will have these tokens = {‘i’, ‘love’, ‘cs3233’, ‘competitive’, ‘programming’, ‘i’, ‘also’, ‘love’, ‘algorithm’}. (a) How to store an array of strings? (b) How to tokenize a string? 5. After that, we want to sort this array of strings lexicographically2 and then ﬁnd the lexico- graphically smallest string. That is, we want to have tokens sorted like this: {‘algorithm’, ‘also’, ‘competitive’, ‘cs3233’, ‘i’, ‘i’, ‘love’, ‘love’, ‘programming’}. The answer for this example is ‘algorithm’. (a) How to sort an array of strings lexicographically? 6. Now, identify which word appears the most in T. To do this, we need to count the frequency of each word. For T, the output is either ‘i’ or ‘love’, as both appear twice. (a) Which data structure best supports this word frequency counting problem? 7. The given text ﬁle has one more line after a line that starts with ‘.......’. The length of this last line is not constrained. Count how many characters are there in the last line? (a) How to read a string when we do not know its length in advance? 2Basically, this is a sort order like the one used in our common dictionary. 152 #################### File: A%20First%20Encounter%20with%20Machine%20Learning%20-%20Max%20Welling%20%28PDF%29.pdf Page: 5 Context: PrefaceInwinterquarter2007ItaughtanundergraduatecourseinmachinelearningatUCIrvine.WhileIhadbeenteachingmachinelearningatagraduatelevelitbecamesoonclearthatteachingthesamematerialtoanundergraduateclasswasawholenewchallenge.Muchofmachinelearningisbuilduponconceptsfrommathematicssuchaspartialderivatives,eigenvaluedecompositions,multivariateprobabilitydensitiesandsoon.Iquicklyfoundthattheseconceptscouldnotbetakenforgrantedatanundergraduatelevel.Thesituationwasaggravatedbythelackofasuitabletextbook.Excellenttextbooksdoexistforthisﬁeld,butIfoundallofthemtobetootechnicalforaﬁrstencounterwithmachinelearning.Thisexperienceledmetobelievetherewasagenuineneedforasimple,intuitiveintroductionintotheconceptsofmachinelearning.Aﬁrstreadtowettheappetitesotospeak,apreludetothemoretechnicalandadvancedtextbooks.Hence,thebookyouseebeforeyouismeantforthosestartingoutintheﬁeldwhoneedasimple,intuitiveexplanationofsomeofthemostusefulalgorithmsthatourﬁeldhastooffer.Machinelearningisarelativelyrecentdisciplinethatemergedfromthegen-eralﬁeldofartiﬁcialintelligenceonlyquiterecently.Tobuildintelligentmachinesresearchersrealizedthatthesemachinesshouldlearnfromandadapttotheiren-vironment.Itissimplytoocostlyandimpracticaltodesignintelligentsystemsbyﬁrstgatheringalltheexpertknowledgeourselvesandthenhard-wiringitintoamachine.Forinstance,aftermanyyearsofintenseresearchthewecannowrecog-nizefacesinimagestoahighdegreeaccuracy.Buttheworldhasapproximately30,000visualobjectcategoriesaccordingtosomeestimates(Biederman).Shouldweinvestthesameefforttobuildgoodclassiﬁersformonkeys,chairs,pencils,axesetc.orshouldwebuildsystemstocanobservemillionsoftrainingimages,somewithlabels(e.g.inthesepixelsintheimagecorrespondtoacar)butmostofthemwithoutsideinformation?Althoughthereiscurrentlynosystemwhichcanrecognizeevenintheorderof1000objectcategories(thebestsystemcangetiii #################### File: A%20First%20Encounter%20with%20Machine%20Learning%20-%20Max%20Welling%20%28PDF%29.pdf Page: 3 Context: ContentsPrefaceiiiLearningandIntuitionvii1DataandInformation11.1DataRepresentation.........................21.2PreprocessingtheData.......................42DataVisualization73Learning113.1InaNutshell.............................154TypesofMachineLearning174.1InaNutshell.............................205NearestNeighborsClassiﬁcation215.1TheIdeaInaNutshell........................236TheNaiveBayesianClassiﬁer256.1TheNaiveBayesModel......................256.2LearningaNaiveBayesClassiﬁer.................276.3Class-PredictionforNewInstances.................286.4Regularization............................306.5Remarks...............................316.6TheIdeaInaNutshell........................317ThePerceptron337.1ThePerceptronModel.......................34i #################### File: Data%20Mining%20Concepts%20and%20Techniques%20-%20Jiawei%20Han%2C%20Micheline%20Kamber%2C%20Jian%20Pei%20%28PDF%29.pdf Page: 118 Context: 2.7 Bibliographic Notes 81 (c) Numeric attributes (d) Term-frequency vectors 2.6 Given two objects represented by the tuples (22, 1, 42, 10) and (20, 0, 36, 8): (a) Compute the Euclidean distance between the two objects. (b) Compute the Manhattan distance between the two objects. (c) Compute the Minkowski distance between the two objects, using q = 3. (d) Compute the supremum distance between the two objects. 2.7 The median is one of the most important holistic measures in data analysis. Pro- pose several methods for median approximation. Analyze their respective complexity under different parameter settings and decide to what extent the real value can be approximated. Moreover, suggest a heuristic strategy to balance between accuracy and complexity and then apply it to all methods you have given. 2.8 It is important to deﬁne or select similarity measures in data analysis. However, there is no commonly accepted subjective similarity measure. Results can vary depending on the similarity measures used. Nonetheless, seemingly different similarity measures may be equivalent after some transformation. Suppose we have the following 2-D data set: | | A

Given a new data point, x = (1.4,1.6) as a query, rank the database points based on similarity with the query using Euclidean distance, Manhattan distance, supremum distance, and cosine similarity. (b) Normalize the data set to make the norm of each data point equal to 1. Use Euclidean distance on the transformed data to rank the data points. 2.7 Bibliographic Notes Methods for descriptive data summarization have been studied in the statistics literature long before the onset of computers. Good summaries of statistical descriptive data min- ing methods include Freedman, Pisani, and Purves [FPP07] and Devore [Dev95].

TIPS TO BE COMPETITIVE c ⃝Steven & Felix Additionally, we have a few other rules of thumb that are useful in programming contests: • 210 = 1, 024 ≈103, 220 = 1, 048, 576 ≈106. • Max 32-bit signed integer: 231 −1 ≈2 × 109 (safe for up to ≈9 decimal digits); Max 64-bit signed integer (long long) is 263 −1 ≈9×1018 (safe for up to ≈18 decimal digits). Use ‘unsigned’ if slightly higher positive number is needed [0..264 −1]. If you need to store integers ≥264, you need to use the Big Integer technique (Section 5.3). • Program with nested loops of depth k running about n iterations each has O(nk) complexity. • If your program is recursive with b recursive calls per level and has L levels, the program has roughly O(bL) complexity. But this is an upper bound. The actual complexity depends on what actions done per level and whether some pruning are possible. • There are n! permutations and 2n subsets (or combinations) of n elements. • Dynamic Programming algorithms which ﬁll in a 2D matrix in O(k) per cell is in O(k × n2). More details in Section 3.5 later. • The best time complexity of a comparison-based sorting algorithm is Ω(n log2 n). • Most of the time, O(n log2 n) algorithms will be suﬃcient for most contest problems. • The largest input size for typical programming contest problems must be << 1M, because beyond that, the time needed to read the input (the I/O routine) will be the bottleneck. Exercise 1.2.2: Please answer the following questions below using your current knowledge about classic algorithms and their time complexities. After you have ﬁnished reading this book once, it may be beneﬁcial to re-attempt this exercise again. 1. There are n webpages (1 ≤n ≤10M). Each webpage i has diﬀerent page rank ri. You want to pick the top 10 pages with highest page ranks. Which method is more feasible? (a) Load all n webpages’ page rank to memory, sort (Section 2.2.1), and pick the top 10. (b) Use priority queue data structure (heap) (Section 2.2.2). 2. Given a list L of up to 10K integers. You need to frequently ask the value of sum(i, j), i.e. the sum of L[i] + L[i+1] + ...+ L[j]. Which data structure should you use? (a) Simple Array (Section 2.2.1). (b) Simple Array that is pre-processed with Dynamic Programming (Section 2.2.1 & 3.5). (c) Balanced Binary Search Tree (Section 2.2.2). (d) Hash Table (Section 2.2.2). (e) Segment Tree (Section 2.3.3). (f) Fenwick Tree (Section 2.3.4). (g) Suﬃx Tree (Section 6.6.2). (h) Suﬃx Array (Section 6.6.4). 3. Given a set S of N points randomly scattered on 2D plane, N ≤1000. Find two points ∈S that has the greatest Euclidian distance. Is O(N2) complete search algorithm that try all possible pairs feasible? (a) Yes, such complete search is possible. (b) No, we must ﬁnd another way. 7 #################### File: Competitive%20Programming%2C%202nd%20Edition%20-%20Steven%20Halim%20%28PDF%29.pdf Page: 13 Context: CONTENTS c ⃝Steven & Felix

CHAPTER NOTES c ⃝Steven & Felix 1.4 Chapter Notes This and subsequent chapters are supported by many text books (see Figure 1.4 in the previous page) and Internet resources. Here are some additional references: • To improve your typing skill as mentioned in Tip 1, you may want to play lots of typing games that are available online. • Tip 2 is an adaptation from the introduction text in USACO training gateway [29]. • More details about Tip 3 can be found in many CS books, e.g. Chapter 1-5, 17 of [3]. • Online references for Tip 4 are: http://www.cppreference.com and http://www.sgi.com/tech/stl/ for C++ STL; http://java.sun.com/javase/6/docs/api for Java API. • For more insights to do better testing (Tip 5), a little detour to software engineering books may be worth trying. • There are many other Online Judges apart from those mentioned in Tip 6, e.g. – POJ http://acm.pku.edu.cn/JudgeOnline, – TOJ http://acm.tju.edu.cn/toj, – ZOJ http://acm.zju.edu.cn/onlinejudge/, – Ural/Timus OJ http://acm.timus.ru, etc. • For a note regarding team contest (Tip 7), read [7]. In this chapter, we have introduced the world of competitive programming to you. However, you cannot say that you are a competitive programmer if you can only solve Ad Hoc problems in every programming contest. Therefore, we do hope that you enjoy the ride and continue reading and learning the other chapters of this book, enthusiastically. Once you have ﬁnished reading this book, re-read it one more time. On the second round, attempt the various written exercises and the ≈ 1198 programming exercises as many as possible. There are ≈149 UVa (+ 11 others) programming exercises discussed in this chapter. (Only 34 in the ﬁrst edition, a 371% increase). There are 19 pages in this chapter. (Only 13 in the ﬁrst edition, a 46% increase). 19 #################### File: A%20MACHINE%20MADE%20THIS%20BOOK%20ten%20sketches%20of%20computer%20science%20-%20JOHN%20WHITINGTON%20%28PDF%29.pdf Page: 9

compression algorithm, computer science students might also find it useful. However, nothing prevents any people who is curious about BIOS technology to read this book and get benefit from it. Some prerequisite knowledge is needed to fully understand this book. It is not mandatory, but it will be very difficult to grasp some of the concepts without it. The most important knowledge is the understanding of x86 assembly language. Explanation of the disassembled code resulting from the BIOS binary and also the sample BIOS patches are presented in x86 assembly language. They are scattered throughout the book. Thus, it’s vital to know x86 assembly language, even with very modest familiarity. It’s also assumed that the reader have some familiarity with C programming language. The chapter that dwell on expansion ROM development along with the introductory chapter in BIOS related software development uses C language heavily for the example code. C is also used heavily in the section that covers IDA Pro scripts and plugin development. IDA Pro scripts have many similarities with C programming language. Familiarity with Windows Application Programming Interface (Win32API) is not a requirement, but is very useful to grasp the concept in the Optional section of chapter 3 that covers IDA Pro plugin development. THE ORGANIZATION The first part of the book lays the foundation knowledge to do BIOS reverse engineering and Expansion ROM development. In this part, the reader is introduced with: a. Various bus protocols in use nowadays within the x86 platform, i.e. PCI, HyperTransport and PCI-Express. The focus is toward the relationship between BIOS code execution and the implementation of protocols. b. Reverse engineering tools and techniques needed to carry out the tasks in later chapter, mostly introduction to IDA Pro disassembler along with its advanced techniques. c. Crash course on advanced compiler tricks needed to develop firmware. The emphasis is in using GNU C compiler to develop a firmware framework. The second part of this book reveals the details of motherboard BIOS reverse engineering and modification. This includes indepth coverage of BIOS file structure, algorithms used within the BIOS, explanation of various BIOS specific tools from its corresponding vendor and explanation of tricks to perform BIOS modification. The third part of the book deals with the development of PCI expansion ROM. In this part, PCI Expansion ROM structure is explained thoroughly. Then, a systematic PCI expansion ROM development with GNU tools is presented. The fourth part of the book deals heavily with the security concerns within the BIOS. This part is biased toward possible implementation of rootkits within the BIOS and possible exploitation scenario that might be used by an attacker by exploiting the BIOS flaw. Computer security experts will find a lot of important information in this part. This part is the central theme in this book. It’s presented to improve the awareness against malicious code that can be injected into BIOS. The fifth part of the book deals with the application of BIOS technology outside of its traditional space, i.e. the PC. In this chapter, the reader is presented with various application of the BIOS technology in the emerging embedded x86 platform. In the end of this part, further application of the technology presented in this book is explained briefly. Some explanation regarding the OpenBIOS and Extensible Firmware Interface (EFI) is also presented. SOFTWARE TOOLS COMPATIBILITY This book mainly deals with reverse engineering tools running in windows operating system. However, in chapters that deal with PCI Expansion ROM development, an x86 Linux installation #################### File: A%20MACHINE%20MADE%20THIS%20BOOK%20ten%20sketches%20of%20computer%20science%20-%20JOHN%20WHITINGTON%20%28PDF%29.pdf Page: 13 Context: AMACHINEMADETHISBOOKtensketchesofcomputerscience #################### File: Competitive%20Programming%2C%202nd%20Edition%20-%20Steven%20Halim%20%28PDF%29.pdf Page: 29 Context: 1.3. GETTING STARTED: THE AD HOC PROBLEMS c ⃝Steven & Felix 1.3 Getting Started: The Ad Hoc Problems We end this chapter by asking you to start with the ﬁrst problem type in ICPCs and IOIs: the Ad Hoc problems. According to USACO [29], Ad Hoc problems are problems that ‘cannot be classiﬁed anywhere else’, where each problem description and its corresponding solution are ‘unique’. Ad Hoc problems almost always appear in a programming contest. Using a benchmark of total 10 problems, there may be 1-2 Ad Hoc problems in an ICPC. If the Ad Hoc problem is easy, it will usually be the ﬁrst problem solved by the teams in a programming contest. But there exists Ad Hoc problems that are complicated to code and some teams will strategically defer solving them until the last hour. Assuming a 60-teams contest, your team is probably in the lower half (rank 30-60) if your team can only do this type of problem during an ICPC regional contest. In IOI 2009 and 2010, there exists 1 easy task per competition day7, which is usually an Ad Hoc task. If you are an IOI contestant, you will deﬁnitely not going to get any medal by only solving these 2 easy Ad Hoc tasks over 2 competition days. However, the faster you can clear these 2 easy tasks, the more time that you will have to work on the other 2 × 3 = 6 challenging tasks. To help you pick which problems to start with among the ≈2950 problems in UVa online judge [28] (and some other online judges), we have listed many Ad Hoc problems that we have solved into several sub-categories below. Each category still contains a lot of problems, so we highlight up to maximum three (3) must try * problems in each category. These are the problems that we think are more interesting or have better quality. We believe that you can solve most of these problems without using advanced data structures or algorithms that will be discussed in the latter chapters. Many of these Ad Hoc problems are ‘simple’ but some of them maybe ‘tricky’. Now, try to solve few problems from each category before reading the next chapter. The categories: • (Super) Easy You should get these problems AC8 in under 7 minutes each! If you are new with competitive programming, we strongly recommend that you start your journey by solving some problems from this category. • Game (Card) There are lots of Ad Hoc problems involving popular games. The ﬁrst game type is re- lated to cards. Usually you will need to parse the string input as normal cards have suits (D/Diamond/♦, C/Club/♣, H/Heart/♥, and S/Spades/♠) on top of the ranks (usually: 2 < 3 < . . . < 9 < T/Ten < J/Jack < Q/Queen < K/King < A/Ace9). It may be a good idea to map these complicated strings to integer indices. For example, one possible mapping is to map D2 →0, D3 →1, . . . , DA →12, C2 →13, C3 →14, . . . , SA →51. Then, we work with the integer indices instead. • Game (Chess) Another popular games that sometimes appear in programming contest problems are chess problems. Some of them are Ad Hoc (listed in this section). Some of them are combinatorial, like counting how many ways to put 8-queens in 8 × 8 chess board (listed in Chapter 3). • Game (Others) Other than card and chess games, there are many other popular problems related to other games that make their way into programming contest problems: Tic Tac Toe, Rock-Paper- Scissors, Snakes/Ladders, BINGO, Bowling, and several others. Knowing the details of the game is helpful, but most of the game rules are given in the problem description to avoid disadvantaging contestants who have not played those games before. 7This is no longer true in IOI 2011. 8However, do not feel bad if you fail to do so. There are reasons why a code does not get AC response. Once you are more familiar with competitive programming, you will ﬁnd that these problems are indeed super easy. 9In some other arrangement, A/Ace < 2. 13 #################### File:

in this book. If they appear, they will be written using this font. Many of them use typedefs, shortcuts, or macros that are commonly used by competitive programmers to speed up the coding time. In this short section, we list down several examples. Java support has been increased substantially in the second edition of this book. This book uses Java which, as of now, does not support macros and typedefs. // Suppress some compilation warning messages (only for VC++ users) #define _CRT_SECURE_NO_DEPRECATE // Shortcuts for "common" data types in contests typedef long long ll; // comments that are mixed with code typedef pair ii; // are aligned to the right like this typedef vector vii; typedef vector vi; #define INF 1000000000 // 1 billion, safer than 2B for Floyd Warshall’s // Common memset settings //memset(memo, -1, sizeof memo); // initialize DP memoization table with -1 //memset(arr, 0, sizeof arr); // to clear array of integers // Note that we abandon the usage of "REP" and "TRvii" in the second edition // to reduce the confusion encountered by new programmers The following shortcuts are frequently used in our C/C++/Java codes in this book: // ans = a ? b : c; // to simplify: if (a) ans = b; else ans = c; // index = (index + 1) % n; // from: index++; if (index >= n) index = 0; // index = (index + n - 1) % n; // from: index--; if (index < 0) index = n - 1; // int ans = (int)((double)d + 0.5); // for rounding to nearest integer // ans = min(ans, new_computation) // we frequently use this min/max shortcut // some codes uses short circuit && (AND) and || (OR) Problem Categorization As of 1 August 2011, Steven and Felix – combined – have solved 1502 UVa problems (≈51% of the entire UVa problems). About ≈1198 of them are discussed and categorized in this book. These problems are categorized according to a ‘load balancing’ scheme: If a problem can be classiﬁed into two or more categories, it will be placed in the category with a lower number of problems. This way, you may ﬁnd problems ‘wrongly’ categorized or problems whose category does not match the technique you use to solve it. What we can guarantee is this: If you see problem X in category Y, then you know that we have solved problem X with the technique mentioned in the section that discusses category Y. If you need hints for any of the problems, you may turn to the index at the back of this book and save yourself the time needed to ﬂip through the whole book to understand any of the problems. The index contains a sorted list of UVa/LA problems number (do a binary search!) which will help locate the pages that contains the discussion of those problems (and the required data structures and/or algorithms to solve that problem). Utilize this categorization feature for your training! To diversify your problem solving skill, it is a good idea to solve at least few problems from each category, especially the ones that we highlight as must try * (we limit ourself to choose maximum 3 highlights per category). xii #################### File: A%20First%20Encounter%20with%20Machine%20Learning%20-%20Max%20Welling%20%28PDF%29.pdf Page: 16 Context: 4CHAPTER1.DATAANDINFORMATION1.2PreprocessingtheDataAsmentionedintheprevioussection,algorithmsarebasedonassumptionsandcanbecomemoreeffectiveifwetransformthedataﬁrst.Considerthefollowingexample,depictedinﬁgure??a.Thealgorithmweconsistsofestimatingtheareathatthedataoccupy.Itgrowsacirclestartingattheoriginandatthepointitcontainsallthedatawerecordtheareaofcircle.Intheﬁgurewhythiswillbeabadestimate:thedata-cloudisnotcentered.Ifwewouldhaveﬁrstcentereditwewouldhaveobtainedreasonableestimate.Althoughthisexampleissomewhatsimple-minded,therearemany,muchmoreinterestingalgorithmsthatassumecentereddata.Tocenterdatawewillintroducethesamplemeanofthedata,givenby,E[X]i=1NNXn=1Xin(1.1)Hence,foreveryattributeiseparately,wesimpleaddalltheattributevalueacrossdata-casesanddividebythetotalnumberofdata-cases.Totransformthedatasothattheirsamplemeaniszero,weset,X′in=Xin−E[X]i∀n(1.2)ItisnoweasytocheckthatthesamplemeanofX′indeedvanishes.Anillustra-tionoftheglobalshiftisgiveninﬁgure??b.Wealsoseeinthisﬁgurethatthealgorithmdescribedabovenowworksmuchbetter!Inasimilarspiritascentering,wemayalsowishtoscalethedataalongthecoordinateaxisinordermakeitmore“spherical”.Considerﬁgure??a,b.Inthiscasethedatawasﬁrstcentered,buttheelongatedshapestillpreventedusfromusingthesimplisticalgorithmtoestimatetheareacoveredbythedata.Thesolutionistoscaletheaxessothatthespreadisthesameineverydimension.Todeﬁnethisoperationweﬁrstintroducethenotionofsamplevariance,V[X]i=1NNXn=1X2in(1.3)wherewehaveassumedthatthedatawasﬁrstcentered.Notethatthisissimilartothesamplemean,butnowwehaveusedthesquare.Itisimportantthatwehaveremovedthesignofthedata-cases(bytakingthesquare)becauseotherwisepositiveandnegativesignsmightcanceleachotherout.Byﬁrsttakingthesquare,alldata-casesﬁrstgetmappedtopositivehalfoftheaxes(foreachdimensionor #################### File: Analytic%20Geometry%20%281922%29%20-%20Lewis%20Parker%20Siceloff%2C%20George%20Wentworth%2C%20David%20Eugene%20Smith%20%28PDF%29.pdf Page: 1 Context: CONTENTS CHAPTER I.

CHAPTER NOTES c ⃝Steven & Felix 3.6 Chapter Notes Many problems in ICPC or IOI require one or combination (see Section 8.2) of these problem solving paradigms. If we have to nominate a chapter in this book that contestants have to really master, we will choose this one. The main source of the ‘Complete Search’ material in this chapter is the USACO training gateway [29]. We adopt the name ‘Complete Search’ rather than ‘Brute-Force’ as we believe that some Complete Search solution can be clever and fast enough, although it is complete. We believe the term ‘clever Brute-Force’ is a bit self-contradicting. We will discuss some more advanced search techniques later in Section 8.3, e.g. A* Search, Depth Limited Search (DLS), Iterative Deepening Search (IDS), Iterative Deepening A* (IDA*). Divide and Conquer paradigm is usually used in the form of its popular algorithms: binary search and its variants, merge/quick/heap sort, and data structures: binary search tree, heap, segment tree, etc. We will see more D&C later in Computational Geometry (Section 7.4). Basic Greedy and Dynamic Programming (DP) techniques techniques are always included in popular algorithm textbooks, e.g. Introduction to Algorithms [3], Algorithm Design [23], Algorithm [4]. However, to keep pace with the growing diﬃculties and creativity of these techniques, especially the DP techniques, we include more references from Internet: TopCoder algorithm tutorial [17] and recent programming contests. In this book, we will revisit DP again on four occasions: Floyd Warshall’s DP algorithm (Section 4.5), DP on (implicit) DAG (Section 4.7.1), DP on String (Section 6.5), and More Advanced DP (Section 8.4). However, for some real-life problems, especially those that are classiﬁed as NP-Complete [3], many of the approaches discussed so far will not work. For example, 0-1 Knapsack Problem which has O(NS) DP complexity is too slow if S is big; TSP which has O(N2 ×2N) DP complexity is too slow if N is much larger than 16. For such problems, people use heuristics or local search: Tabu Search [15, 14], Genetic Algorithm, Ants Colony Optimization, Beam Search, etc. There are ≈179 UVa (+ 15 others) programming exercises discussed in this chapter. (Only 109 in the ﬁrst edition, a 78% increase). There are 32 pages in this chapter. (Also 32 in the ﬁrst edition, but some content have been reorganized to Chapter 4 and 8). 70 #################### File:
