.1 A suggested sequence of chapters for a short introductory course.
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

(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<br>1 | A<br>2 |
| -------- | -------- | -------- |
| x<br>1 | 1.5 | 1.7 |
| x<br>2 | 2 | 1.9 |
| x3 | 1.6 | 1.8 |
| x<br>4 | 1.2 | 1.5 |
| x<br>5 | 1.5 | 1.0 |
(a) 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.
(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.

Context: architecture) and 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

Context: Part I The Basics  Chapter 1 PC BIOS Technology   PREVIEW   This chapter is devoted to explaining the parts of a PC that make up the term basic input/output system (BIOS). These are not only motherboard BIOS, which most readers might already be accustomed to, but also expansion read-only memories (ROMs). The BIOS is one of the key parts of a PC. BIOS provides the necessary execution environment for the operating system. The approach that I take to explain this theme follows the logic of the execution of BIOS subsystems inside the PC. It is one of the fastest ways to gain a systematic understanding of BIOS technology. In this journey, you will encounter answers to common questions: Why is it there? Why does it have to be accomplished that way? The discussion starts with the most important BIOS, motherboard BIOS. On top of that, this chapter explains contemporary bus protocol technology, i.e., PCI Express, HyperTransport, and peripheral component interconnect (PCI). A profound knowledge of bus protocol technology is needed to be able to understand most contemporary BIOS code.   1.1. Motherboard BIOS   Motherboard BIOS is the most widely known BIOS from all kinds of BIOS. This term refers to the machine code that resides in a dedicated ROM chip on the motherboard. Today, most of these ROM chips are the members of flash-ROM family. This name refers to a ROM chip programmed1 electrically in a short interval, i.e., the programming takes only a couple of seconds.  There is a common misconception between the BIOS chip and the complementary metal oxide semiconductor (CMOS) chip. The former is the chip that's used to store the BIOS code, i.e., the machine code that will be executed when the processor executes the BIOS, and the latter is the chip that's used to store the BIOS parameters, i.e., the parameters that someone sets when entering the BIOS, such as the computer date and the RAM timing. Actually, CMOS chip is a misleading name. It is true that the chip is built upon CMOS technology. However, the purpose of the chip is to store BIOS information with the help of a dedicated battery. In that respect, it should’ve been called non-volatile random access memory (NVRAM) chip in order to represent the nature and purpose of the chip. Nonetheless, the CMOS chip term is used widely among PC users and hardware vendors.                                                   1 Programmed in this context means being erased or written into.   1

Context: Chapter 2 Preliminary Reverse Code Engineering   PREVIEW   This chapter introduces software reverse engineering1 techniques by using IDA Pro disassembler. Techniques used in IDA Pro to carry out reverse code engineering of a flat binary file are presented. BIOS binary flashed into the BIOS chip is a flat binary file.2 That's why these techniques are important to master. The IDA Pro advanced techniques presented include scripting and plugin development. By becoming acquainted with these techniques, you will able to carry out reverse code engineering in platforms other than x86.   2.1. Binary Scanning   The first step in reverse code engineering is not always firing up the disassembler and dumping the binary file to be analyzed into it, unless you already know the structure of the target binary file. Doing a preliminary assessment on the binary file itself is recommended for a foreign binary file. I call this preliminary assessment binary scanning, i.e., opening up the binary file within a hex editor and examining the content of the binary with it. For an experienced reverse code engineer, sometimes this step is more efficient rather than firing up the disassembler. If the engineer knows intimately the machine architecture where the binary file was running, he or she would be able to recognize key structures within the binary file without firing up a disassembler. This is sometimes encountered when an engineer is analyzing firmware.  Even a world-class disassembler like IDA Pro seldom has an autoanalysis feature for most firmware used in the computing world. I will present an example for such a case. Start by opening an Award BIOS binary file with Hex Workshop version 4.23. Open a BIOS binary file for the Foxconn 955X7AA-8EKRS2 motherboard. The result is shown in figure 2.1.                                                    1 Software reverse engineering is also known as reverse code engineering. It is sometimes abbreviated as RCE. 2 A flat binary file is a file that contains only the raw executable code (possibly with self-contained data) in it. It has no header of any form, unlike an executable file that runs within an operating system. The latter adheres to some form of file format and has a header so that it can be recognized and handled correctly by the operating system.   1

Context: Chapter 10 Low-Level Remote Server Management   PREVIEW   You might not be aware of the presence of low-level remote access to x86 system hardware and firmware through software interfaces called the desktop management interface (DMI) and system management basic input/output system (SMBIOS). They were competing standards. DMI reached the end of its life cycle in 2005. Therefore, my explanation regarding these protocols focuses on SMBIOS. Nevertheless, some artifacts from the DMI era are still found in SMBIOS for compatibility reasons. The first section explains the SMBIOS interface, and the second section deals with the real-world implementation of the interface in a sample BIOS binary, along with a simple SMBIOS structure table parser. You also get a glimpse of Windows management instrumentation (WMI).   10.1. DMI and SMBIOS   DMI and SMBIOS are standards developed and maintained by the Distributed Management Task Force (DMTF). These standards are meant to take part in a software layer to provide seamless remote management for server and desktop machines. The purpose is to lower the total cost of ownership for organizations running various machines. The more machines an organization has, the greater the benefit it receives from being able to centralize the management tasks of the machines, such as monitoring machine performance and updating certain software. This machine management paradigm is termed Web-based enterprise management (WBEM) by the DMTF (http://www.dmtf.org/standards/wbem/). In this context, DMI or SMBIOS is only one of the software layers that provide management functions. Note that DMI has been deprecated and replaced by SMBIOS.  Figure 10.1 shows a simplified logical architecture for a WBEM computing environment.

Figure 1.2 The world is data rich but information poor.
In summary, the abundance of data, coupled with the need for powerful data analysis
tools, has been described as a data rich but information poor situation (Figure 1.2). The
fast-growing, tremendous amount of data, collected and stored in large and numerous
data repositories, has far exceeded our human ability for comprehension without power-
ful tools. As a result, data collected in large data repositories become “data tombs”—data
archives that are seldom visited. Consequently, important decisions are often made
based not on the information-rich data stored in data repositories but rather on a deci-
sion maker’s intuition, simply because the decision maker does not have the tools to
extract the valuable knowledge embedded in the vast amounts of data. Efforts have
been made to develop expert system and knowledge-based technologies, which typically
rely on users or domain experts to manually input knowledge into knowledge bases.
Unfortunately, however, the manual knowledge input procedure is prone to biases and
errors and is extremely costly and time consuming. The widening gap between data and
information calls for the systematic development of data mining tools that can turn data
tombs into “golden nuggets” of knowledge.
1.2 What Is Data Mining?
It is no surprise that data mining, as a truly interdisciplinary subject, can be deﬁned
in many different ways. Even the term data mining does not really present all the major
components in the picture. To refer to the mining of gold from rocks or sand, we say gold
mining instead of rock or sand mining. Analogously, data mining should have been more

<Hat den Kontext nicht vollständig genutzt> <>

Prompt:
Tut mir leid, ich habe leider nicht verstanden, was du mit deiner Anfrage meinst. Könntest du bitte deine Frage noch einmal genauer formulieren? Ich versuche dann, sie möglichst präzise zu beantworten.Jetzt verstehe ich, was du meinst. Das Verhalten, das du beschreibst, ist problematisch. Wenn der Nutzer während einer laufenden Antwortgenerierung in den Chat klickt oder den Chat zu bearbeiten versucht, sollte das nicht dazu führen, dass die vorherigen Nachrichten verloren gehen. 

Das wäre ein unerwünschtes Verhalten, das die Nutzererfahrung stark beeinträchtigen würde. Stattdessen sollte das System so konzipiert sein, dass es auf solche Aktionen des Nutzers angemessen reagiert, ohne dass dabei Datenverlust auftritt.

Eine mögliche Lösung wäre es, den Nutzer darauf hinzuweisen, dass eine Antwort generiert wird und er den Chat erst nach Abschluss dieses Vorgangs bearbeiten kann. Alternativ könnte das System die Eingaben des Nutzers zwischenspeichern, um sie dann nach Abschluss der Generierung wieder einzufügen.

Was denkst du, wie man dieses Problem am besten angehen könnte, um eine reibungslose Nutzererfahrung sicherzustellen? Ich bin für weitere Vorschläge offen.Die Antwort des Chatbots zur analytischen Geometrie ist im Wesentlichen korrekt und bietet eine prägnante Zusammenfassung der wichtigsten Aspekte dieses Themas. Die analytische Geometrie wird als ein Bereich beschrieben, der geometrische Probleme mithilfe algebraischer Methoden löst, was eine treffende Definition ist.

Hier sind einige Überlegungen zur Antwort:

1. **Definition und Zweck**: Die Antwort erklärt klar, dass die analytische Geometrie Punkte und Linien durch algebraische Symbole und Gleichungen darstellt. Dies ist ein zentraler Punkt, der die Unterscheidung zur elementaren Geometrie verdeutlicht.

Context: 2. **Wichtige Aspekte**: Die genannten Aspekte wie Koordinatensysteme, Gleichungen von Geraden und Kurven sowie die Berechnung geometrischer Größen sind alle relevante und grundlegende Themen der analytischen Geometrie. Diese Punkte sind gut gewählt und bieten einen umfassenden Überblick.

3. **Transformationen und spezielle Kurven**: Die Erwähnung von Transformationen und speziellen Kurven wie Parabeln, Ellipsen und Hyperbeln zeigt, dass die Antwort auch auf fortgeschrittenere Themen eingeht, was für ein vollständiges Verständnis der analytischen Geometrie wichtig ist.

4. **Fehlende Details**: Während die Antwort viele wichtige Punkte abdeckt, könnte sie durch Beispiele oder Anwendungen der analytischen Geometrie ergänzt werden, um die Konzepte greifbarer zu machen. Beispielsweise könnte die Anwendung in der Physik oder in der Computergrafik erwähnt werden.

Insgesamt stimme ich der ursprünglichen Antwort zu, da sie die grundlegenden Konzepte der analytischen Geometrie korrekt und klar darstellt. Eine Ergänzung durch praktische Beispiele oder Anwendungen würde die Antwort jedoch weiter verbessern.

Response:
Es scheint, dass du eine detaillierte Erklärung zu meiner vorherigen Antwort wünschst. Hier ist eine Aufschlüsselung meiner Überlegungen und der Schritte, die ich unternommen habe, um zu dieser Schlussfolgerung zu gelangen:

1. **Verständnis der Anfrage**: Zunächst habe ich die ursprüngliche Anfrage analysiert, um den Kontext und die spezifischen Fragen zu verstehen. Es war wichtig, die Anliegen des Nutzers zu erkennen, um eine präzise Antwort zu formulieren.
