Avoiding False Discoveries: A completely new addition in the second edition is a chapter on how to avoid false discoveries and produce valid results, which is novel among other contemporary textbooks on data mining. It supplements the discussions in the other chapters with a discussion of the statistical concepts (statistical significance, p-values, false discovery rate, permutation testing, etc.) relevant to avoiding spurious results, and then illustrates these concepts in the context of data mining techniques. This chapter addresses the increasing concern over the validity and reproducibility of results obtained from data analysis. The addition of this chapter is a recognition of the importance of this topic and an acknowledgment that a deeper understanding of this area is needed for those analyzing data.

Association Analysis: The changes in association analysis are more localized. We have completely reworked the section on the evaluation of association patterns (introductory chapter), as well as the sections on sequence and graph mining (advanced chapter).

Introduction to Data Mining presents fundamental concepts and algorithms for those learning data mining for the first time. Each concept is explored thoroughly and supported with numerous examples. The text requires only a modest background in mathematics.

Each major topic is organized into two chapters, beginning with basic concepts that provide necessary background for understanding each data mining technique, followed by more advanced concepts and algorithms.

In my opinion this is currently the best data mining text book on the market. I like the comprehensive coverage which spans all major data mining techniques including classification, clustering, and pattern mining (association rules).

Dr. Michael Steinbach is a research scientist in the Department of Computer Science and Engineering at the University of Minnesota, from which he earned a BS degree in Mathematics, an MS degree in Statistics, and MS and PhD degrees in Computer Science. His research interests are in the areas of data mining, machine learning and statistical learning and its applications to fields such as climate, biology and medicine. This research has resulted in more than 100 papers published in the proceedings of major data mining conferences or computer science or domain journals. Previous to his academic career, he held a variety of software engineering, analysis and design positions in industry at Silicon Biology, Racotek and NCR.

Dr. Anuj Karpatne is a Post-Doctoral Associate in the Department of Computer Science and Engineering at the University of Minnesota. He received his M.Tech in Mathematics and Computing from the Indian Institute of Technology Delhi, and a PhD in Computer Science at the University of Minnesota under the guidance of Professor Vipin Kumar. His research interests lie in the development of data mining and machine learning algorithms for solving scientific and socially relevant problems in varied disciplines such as climate science, hydrology and healthcare. His research has been published in top-tier journals and conferences such as SDM, ICDM, KDD, NIPS, TKDE and ACM Computing Surveys.

This course will cover the fundamental topics in data mining including classification, clustering, association analysis, and anomaly detection. The course is aimed towards graduate students who are interested to do research in data mining, machine learning, and other related disciplines.Students are expected to have programming background either in C, C, Java, Python, or other equivalent programming languages in order to do the homework assignments and class project. Some of the homework assignments may require programming in Matlab. Students are also expected to have background in algorithms and data structures, linear algebra, and probability/statistics.

This data mining course introduces the concepts, algorithms, techniques, and applications of data mining. Topics include background of data mining, data preprocessing, classification, clustering, mining association rules, and mining complex types of data from application domains (e.g., relational data, Web data, steam data, and biomedical data). This course is designed for CS graduate students, while senior CS undergraduate students interested in the field are welcome to talk to the instructor to determine whether they are qualified for taking this course.

I'm a novice who is going to start reading about data mining. I have basic knowledge of AI and statistics. Since many say that machine learning also plays an important role in data mining, is it necessary to read about machine learning before I could go on with data mining?

Thirdly, get some data, and start attempting to analyse data. You'll need to split into training and test sets, and then build models on the training set and test them against the test set. I found the caret package for R very useful for all of this. After that its practice, practice practice (like almost everything else).

On the other hand, if you are interested in predictive data mining, then machine learning will help you understand that you try to minimize the unknown risk (expectation of the loss function) when minimizing the empirical risk: you will keep in mind overfitting, generalization error and cross-validation. For instance, for a matter of consistency, the $k$-NN for a training sample of size $n$ should be such that:

Course Description:With the advent of web technology and the availability of massive amounts of data, the traditional approach of "algorithm driven science" is moving towards "data driven science".In recent years, data mining has emerged as a promising tool for solving problems in various application domains. A well-rounded methodology for interpretation and learning from data must be based on a collective combination of data modeling, algorithmic design, prototyping and extensive experimentation along with the interpretation of the results. The underlying principle of data mining is to develop robust algorithms for obtaining useful information from huge amounts of data amassed. Automatically modeling, organizing and interpreting the available data not only enables intelligent manipulation later on but also removes all the unwanted and unnecessary information.

There will be five written homework assignments.Homework problems might constitute some programming exercises that are designed to understand the performance of data mining algorithms.Students are encouraged to talk and discuss with other students to improve their conceptual understanding, but the final submission must be their own work.If any help is taken from others, please acknowledge the people from whom you received some help.Any homework turned in late will be penalized 10% for each late day.

One of the major components of this course is the final project.In this project, students will investigate some interesting aspect of a data mining algorithm and apply it to a real-world problem.The main purpose of this project is to enable the students to get some hands-on experience in the design and implementation of a practical data mining system.In addition to the core computer science aspect, the performance of a data mining system significantly depends on some specific domain-dependent expert knowledge in the application field (such as bioinformatics, business intelligence, e-commerce, etc.). More details about the project proposal and project submission will be provided on the course webpage later.

I am currently reading Data Mining Concepts and Techniques by Jian Pei.This book is a whole lot of theory and not much engrossing.Can someone please suggest a more practical approach oriented book which illustrates the concepts by using practical examples with data.
