About NPTEL Data Mining Course:

Data mining is study of algorithms for finding patterns in large data sets. It is an integral part of modern industry, where data from its operations and customers are mined for gaining business insight. It is also important in modern scientific endeavors. Data mining is an interdisciplinary topic involving, databases, machine learning and algorithms. The course will cover the fundamentals of data mining. It will explain the basic algorithms like data preprocessing, association rules, classification, clustering, sequence mining and visualization. It will also explain implementations in open source software. Finally, case studies on industrial problems will be demonstrated.

Course Layout:

  • Week 1:聽Introduction, Data Preprocessing聽
  • Week 2:聽Association Rule Mining, Classification Basics
  • Week 3:聽Decision Tree, Bayes Classifier, K nearest neighbor聽
  • Week 4:Support Vector Machine, Kernel Machine聽
  • Week 5:聽Clustering, Outlier detection聽
  • Week 6:聽Sequence mining聽
  • Week 7:聽Evaluation, Visualization.聽
  • Week 8:聽Case studies聽
CRITERIA TO GET A CERTIFICATE:

Average assignment score = 25% of average of best 8 assignments out of the total 12 assignments given in the course.
Exam score = 75% of the proctored certification exam score out of 100

Final score = Average assignment score + Exam score

YOU WILL BE ELIGIBLE FOR A CERTIFICATE ONLY IF AVERAGE ASSIGNMENT SCORE >=10/25 AND EXAM SCORE >= 30/75. If one of the 2 criteria is not met, you will not get the certificate even if the Final score >= 40/100.
