Introduction

@(Pattern Discovery in Data Mining)[Data Mining, Notes]
Jiawei Han的Pattern Discovery课程笔记

Why data mining?

data explosion and abundant(but unstructured) data everywhere
drowning in data but starving in knowledge
keyword: interdisciplinary

Data mining is to mine knowledge from data.

Data Mining Process

Q: DM中的模式，有两种，一种是人们根据自己的假设来推论出来的；另一种是纯粹机器挖掘出来的，两种分别在什么情况下更有用？

Q: What is “Pattern”?
A: A set of items, subsequences, or substructures that occur
frequently together (or strongly correlated) in a data set

Data Mining in different views

Data View: What kinds of data?

1. structured data(relational data, object-relational data, transaction data, data warehouse data)
2. unstructured data(text data, web data, stream data, social network data, information networks, multimedia data, time-series data, temporal data, sequence data)

Knowledge View

Methodology View

DM is a confluence of many different disciplines.
* Machine learning, statistics and pattern recognition play great role in DM.
* Application is the driver of DM.
* Algorithm, database technology and distributed/cloud computing are also important methodologies in DM.

Application View

• Mining text data and mining the Web
  Web page classification and ranking, Weblog analysis, recommender systems, …
  Mining business data
• Transaction data, market basket analysis, fraud detection, …
  Data mining and software/system engineering, e.g., mining software bugs
• Mining biological and medical data
  Gene, protein, microarray data, biological networks
• Mining social and information networks
  Community discovery, information propagation, …
• Invisible data mining
