3.3 Giga base-pairs — Human Genome Project 6.1 Overview and Motivation In this chapter, we present one more topic that is tested in ICPC – although not as frequent as graph and mathematics problems – namely: string processing. String processing is common in the research field of bioinformatics. However, as the strings that researchers deal with are usually extremely long, efficient data structures and algorithms were necessary. Some of these problems are presented as contest problems in ICPCs. By mastering the content of this chapter, ICPC contestants will have a better chance at tackling those string processing problems. String processing tasks also appear in IOI, but usually they do not require advanced string data structures or algorithms due to syllabus [10] restriction. Additionally, the input and output format of IOI tasks are usually simple1. This eliminates the need to code tedious input parsing or output formatting commonly found in ICPC problems. IOI tasks that require string processing are usually still solvable using the problem solving paradigms mentioned in Chapter 3. It is sufficient for IOI contestants to skim through all sections in this chapter except Section 6.5 about string processing with DP. However, we believe that it may be advantageous for IOI contestants to learn some of the more advanced materials outside of their syllabus. 6.2 Basic String Processing Skills We begin this chapter by listing several basic string processing skills that every competitive pro- grammer must have. In this section, we give a series of mini tasks that you should solve one after another without skipping. You can use your favorite programming language (C, C++, or Java). Try your best to come up with the shortest, most efficient implementation that you can think of. Then, compare your implementations with ours (see Appendix A). If you are not surprised with any of our implementations (or can even give simpler implementations), then you are already in a good shape for tackling various string processing problems. Go ahead and read the next sections. Otherwise, please spend some time studying our implementations. 1. Given a text file that contains only alphabet characters [A-Za-z], digits [0-9], space, and period (‘.’), write a program to read this text file line by line until we encounter a line that starts with seven periods (‘‘.......’’). Concatenate (combine) each line into one long string T. When two lines are combined, give one space between them so that the last word of the previous line is separated from the first word of the current line. There can be up to 30 characters per line and no more than 10 lines for this input block. There is no trailing space at the end of each line. Note: The sample input text file ‘ch6.txt’ is shown on the next page; After question 1.(d) and before task 2. 1IOI 2010-2011 require contestants to implement function interfaces instead of coding I/O routines. 151 #################### File: Data%20Mining%20Concepts%20and%20Techniques%20-%20Jiawei%20Han%2C%20Micheline%20Kamber%2C%20Jian%20Pei%20%28PDF%29.pdf Page: 717 Context:

base-pairs — Human Genome Project 6.1 Overview and Motivation In this chapter, we present one more topic that is tested in ICPC – although not as frequent as graph and mathematics problems – namely: string processing. String processing is common in the research field of bioinformatics. However, as the strings that researchers deal with are usually extremely long, efficient data structures and algorithms were necessary. Some of these problems are presented as contest problems in ICPCs. By mastering the content of this chapter, ICPC contestants will have a better chance at tackling those string processing problems. String processing tasks also appear in IOI, but usually they do not require advanced string data structures or algorithms due to syllabus [10] restriction. Additionally, the input and output format of IOI tasks are usually simple1. This eliminates the need to code tedious input parsing or output formatting commonly found in ICPC problems. IOI tasks that require string processing are usually still solvable using the problem solving paradigms mentioned in Chapter 3. It is sufficient for IOI contestants to skim through all sections in this chapter except Section 6.5 about string processing with DP. However, we believe that it may be advantageous for IOI contestants to learn some of the more advanced materials outside of their syllabus. 6.2 Basic String Processing Skills We begin this chapter by listing several basic string processing skills that every competitive pro- grammer must have. In this section, we give a series of mini tasks that you should solve one after another without skipping. You can use your favorite programming language (C, C++, or Java). Try your best to come up with the shortest, most efficient implementation that you can think of. Then, compare your implementations with ours (see Appendix A). If you are not surprised with any of our implementations (or can even give simpler implementations), then you are already in a good shape for tackling various string processing problems. Go ahead and read the next sections. Otherwise, please spend some time studying our implementations. 1. Given a text file that contains only alphabet characters [A-Za-z], digits [0-9], space, and period (‘.’), write a program to read this text file line by line until we encounter a line that starts with seven periods (‘‘.......’’). Concatenate (combine) each line into one long string T. When two lines are combined, give one space between them so that the last word of the previous line is separated from the first word of the current line. There can be up to 30 characters per line and no more than 10 lines for this input block. There is no trailing space at the end of each line. Note: The sample input text file ‘ch6.txt’ is shown on the next page; After question 1.(d) and before task 2. 1IOI 2010-2011 require contestants to implement function interfaces instead of coding I/O routines. 151 #################### File: Data%20Mining%20Concepts%20and%20Techniques%20-%20Jiawei%20Han%2C%20Micheline%20Kamber%2C%20Jian%20Pei%20%28PDF%29%281%29.pdf Page: 618 Context: HAN19-ch12-543-584-97801238147912011/6/13:25Page581#3912.9Summary58112.9SummaryAssumethatagivenstatisticalprocessisusedtogenerateasetofdataobjects.Anoutlierisadataobjectthatdeviatessignificantlyfromtherestoftheobjects,asifitweregeneratedbyadifferentmechanism.Typesofoutliersincludeglobaloutliers,contextualoutliers,andcollectiveoutliers.Anobjectmaybemorethanonetypeofoutlier.Globaloutliersarethesimplestformofoutlierandtheeasiesttodetect.Acontextualoutlierdeviatessignificantlywithrespecttoaspecificcontextoftheobject(e.g.,aTorontotemperaturevalueof28◦Cisanoutlierifitoccursinthecontextofwinter).Asubsetofdataobjectsformsacollectiveoutlieriftheobjectsasawholedeviatesignificantlyfromtheentiredataset,eventhoughtheindividualdataobjectsmaynotbeoutliers.Collectiveoutlierdetectionrequiresbackgroundinformationtomodeltherelationshipsamongobjectstofindoutliergroups.Challengesinoutlierdetectionincludefindingappropriatedatamodels,thedepen-denceofoutlierdetectionsystemsontheapplicationinvolved,findingwaystodistinguishoutliersfromnoise,andprovidingjustificationforidentifyingoutliersassuch.Outlierdetectionmethodscanbecategorizedaccordingtowhetherthesampleofdataforanalysisisgivenwithexpert-providedlabelsthatcanbeusedtobuildanoutlierdetectionmodel.Inthiscase,thedetectionmethodsaresupervised,semi-supervised,orunsupervised.Alternatively,outlierdetectionmethodsmaybeorganizedaccordingtotheirassumptionsregardingnormalobjectsversusout-liers.Thiscategorizationincludesstatisticalmethods,proximity-basedmethods,andclustering-basedmethods.Statisticaloutlierdetectionmethods(ormodel-basedmethods)assumethatthenormaldataobjectsfollowastatisticalmodel,wheredatanotfollowingthemodelareconsideredoutliers.Suchmethodsmaybeparametric(theyassumethatthedataaregeneratedbyaparametricdistribution)ornonparametric(theylearnamodelforthedata,ratherthanassumingoneapriori).ParametricmethodsformultivariatedatamayemploytheMahalanobisdistance,theχ2-statistic,oramixtureofmul-tipleparametricmodels.Histogramsandkerneldensityes #################### File: BIOS%20Disassembly%20Ninjutsu%20Uncovered%201st%20Edition%20-%20Darmawan%20Salihun%20%28PDF%29%20BIOS_Disassembly_Ninjutsu_Uncovered.pdf Page: 287 Context: • -R means traverse the directories recursively starting from the current directory and include in the tag file the source code information from all traversed directories. • * means create tags in the tag file for every file that ctags can parse.

I condensed the shell output in shell snippet 9.8 to save space. Now, you can traverse the source code using vi. I'll start with flash_rom.c. This file is the main file of the flash_n_burn utility. Open it with vi and find the main function within the file. When you are trying to understand a source code, you have to start with the entry point function. In this case, it's main. Now, you can traverse the source code; to do so, place the cursor in the function call that you want to know and then press Ctrl+] to go to its definition. If you want to know the data structure definition for an object,5 place the cursor in the member variable of the object and press Ctrl+]; vi will take you to the data structure definition. To go back from the function or data structure definition to the calling function, press Ctrl+t. Note that these key presses apply only to vi; other text editors may use different keys. As an example, refer to listing 9.2. Note that I condensed the source code and added some comments to explain the steps to traverse the source code. Listing 9.2 Moving flash_n_burn Source Code // -- file: flash_rom.c -- int main (int argc, char * argv[]) { // Irrelevant code omitted (void) enable_flash_write(); // You will find the definition of this // function. Place the cursor in the // enable_flash_write function call, then // press Ctrl+]. // Irrelevant code omitted } 5 An object is a data structure instance. For example if a data structure is named my_type, then a variable of type my_type is an object, as in my_type a_variable; a_variable is an object. #################### File:

sections definition matches the layout shown in figure 3.4 because the output of the makefile in listing 3.3 is a flat binary file. The SECTION keyword starts the section definition. The .text keyword starts the text section definition, the .rodata keyword starts the read-only data section definition, the .data keyword starts the data section definition, and the .bss keyword starts the base stack segment section. The ALIGN keyword is used to align the starting address of the corresponding section definition to some predefined multiple of bytes. In the preceding section definition, the sections are aligned to a 4-byte boundary except for the text section. The name of the sections can vary depending on the programmer's will. However, the naming convention presented here is encouraged for clarity. Return to the linker script invocation again in listing 3.3: $(LD) $(LDFLAGS) -o $(ROM_OBJ) $(OBJS) In the preceding linker invocation, the output from the linker is another object file represented by the ROM_OBJ constant. How are you going to obtain the flat binary file? The next line and previously defined flags in the makefile clarify this: OBJCOPY= objcopy OBJCOPY_FLAGS= -v -O binary # irrelevant lines omitted... $(OBJCOPY) $(OBJCOPY_FLAGS) $(ROM_OBJ) $(ROM_BIN) In these makefile statements, a certain member of GNU binutils called objcopy is producing the flat binary file from the object file. The -O binary in the OBJCOPY_FLAGS informs the objcopy utility that it should emit the flat binary file from the object file previously linked by the linker. However, it must be noted that objcopy merely copies the relevant content of the object file into the flat binary file; it doesn't alter the layout of the sections in the linked object file. The next line in the makefile is as follows: build_rom $(ROM_BIN) $(ROM_SIZE) This invokes a custom utility to patch the flat binary file into a valid PCI expansion ROM binary. Now you have mastered the basics of using the linker script to generate a flat binary file from C source code and assembly source code. Venture into the next chapters. Further information will be presented in the PCI expansion ROM section of this book. 13 #################### File:

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 mining methods include Freedman, Pisani, and Purves [FP97] and Devore [Dev95]. ### 2.6 Given two objects represented by the tuples (22, 1, 42, 10) and (20, 0, 36, 8): 1. Compute the **Euclidean distance** between the two objects. 2. Compute the **Manhattan distance** between the two objects. 3. Compute the **Minkowski distance** between the two objects, using \( q = 3 \). 4. Compute the **supremum distance** between the two objects. ### 2.7 The median is one of the most important holistic measures in data analysis. Propose 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: | | A1 | A2 | |-----|----|----| | x1 | 1.5| 1.7| | x2 | 2.2| 1.9| | x3 | 1.6| 1.8| | x4 | 1.2| 1.5| | x5 | 1.5| 1.0| 1. Consider the data as 2-D data points. 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**. 2. 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. ``` #################### File: BIOS%20Disassembly%20Ninjutsu%20Uncovered%201st%20Edition%20-%20Darmawan%20Salihun%20%28PDF%29%20BIOS_Disassembly_Ninjutsu_Uncovered.pdf Page: 528 Context: Figure 13.3 Steps in comprehending TCG standards implementation in PC architecture Figure 13.3 shows that the first document you have to read is the TCG Specification Architecture Overview. Then, proceed to the platform-specific design guide document, which in the current context is the PC platform specification document. You have to consult the concepts explained in the TPM main specification, parts 1–4, and the TSS document while reading the PC platform specification document—the dashed blue arrows in figure 13.3 mean "consult." You can download the TCG Specification Architecture Overview and TPM main specification, parts 1–4, at https://www.trustedcomputinggroup.org/specs/TPM. The TSS document is available for download at https://www.trustedcomputinggroup.org/specs/TSS, and the PC platform specification document is available for download at https://www.trustedcomputinggroup.org/specs/PCClient. The PC platform specification document consists of several files; the relevant ones are TCG PC Client–Specific Implementation Specification for Conventional BIOS (as of the writing of this book, the latest version of this document is 1.20 final) and PC Client TPM Interface Specification FAQ. Reading these documents will give you a glimpse of the concepts of trusted computing and some details about its implementation in PC architecture. Before moving forward, I'll explain a bit more about the fundamental concept of trusted computing that is covered by the TCG standards. The TCG Specification Architecture Overview defines trust as the "expectation that a device will behave in a particular manner for a specific purpose." The advanced features that exist in a trusted platform are protected capabilities, integrity measurement, and integrity reporting. The focus is on the integrity measurement feature because this feature relates directly to the BIOS. As per the TCG Specification Architecture Overview, integrity measurement is "the process of obtaining metrics of platform characteristics that affect the integrity (trustworthiness) of a platform; storing those metrics; and putting digests of those metrics in PCRs [platform configuration registers]." I'm not going to delve into this definition or the specifics about PCRs. Nonetheless, it's important to note that in the TCG standards for PC architecture, core root of trust measurement (CRTM) is synonymous with BIOS boot block.

suggested sequence of chapters for a short introductory course. ## Suggested Chapter Sequence 1. Chapter 1: Introduction 2. Chapter 2: Data Preprocessing 3. Chapter 3: Data Analysis 4. Chapter 4: Data Visualization 5. Chapter 5: Data Mining 6. Chapter 6: Basic Classification Methods 7. Chapter 7: Advanced Classification Methods 8. Chapter 8: Clustering 9. Chapter 9: Advanced Pattern Mining 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 orderings. 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 primary 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 exercises offer 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 in the research literature related to the topics and methods presented, in-depth treatment of related topics, and possible extensions. ## To 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: BIOS%20Disassembly%20Ninjutsu%20Uncovered%201st%20Edition%20-%20Darmawan%20Salihun%20%28PDF%29%20BIOS_Disassembly_Ninjutsu_Uncovered.pdf Page: 257 Context: SECTIONS { .text __boot_vect : { *( .text) } = 0x00 .rodata ALIGN(4) : { *( .rodata) } = 0x00 .data ALIGN(4) : { *( .data) } = 0x00 .bss ALIGN(4) : { *( .bss) } = 0x00 } 7.3.3.2.
