Course Description

  1. About the course - Cluster analysis is one of the most popular techniques used in data mining for marketing needs. The idea behind cluster analysis is to find natural groups within data in such a way that each element in the group is as similar to each other as possible. At the same time, the groups are as dissimilar to other groups as possible.
  2. Course materials- The course contains video presentations (power point presentations with voice), pdf, excel work book and sas codes.
  3. Course duration- The course should take roughly 7 hours to understand and internalize the concepts.
  4. Course Structure (contents) The structure of the course is as follows.

Motivation

  • Where one applies cluster analysis. Why one should learn cluster analysis?
  • How it is different from objective segmentation (CHAID / CART )

Statistical foundation and practical application: Understand

  • Different type of cluster analysis
  • Cluster Analysis – high level view
  • Hierarchical clustering –
    • Agglomerative or Divisive technique
    • Dendogram – What it is? What does it show?
    • Scree plot - How to decide about number of clusters
    • How to use SAS command to run hierarchical clustering
    • When and why does on need to standardize the data?
    • How to understand and interpret the output
  • Non-hierarchical clustering (K means clustering).
    • Why do we need k means approach
    • How does it work?
    • How does it iterate?
    • How does it decide about combining old clusters?
    • How to use SAS command to run hierarchical clustering
    • When and why does on need to standardize the data?
    • How to understand and interpret the output

What are the requirements?

  • Basic understanding of statistics
  • Basic knowledge of SAS

Instructor Biography

Gopal Prasad Malakar, Credit Card Analytics Professional - Trains on Data Mining

I am a seasoned Analytics professional with 15+ years of professional experience. I have industry experience of impactful and actionable analytics. I am a keen trainer, who believes that training is all about making users understand the concepts. If students remain confused after the training, the training is useless. I ensure that after my training, students (or partcipants) are crystal clear on how to use the learning in their business scenarios. My expertise is in Credit Card Business, Scoring (econometrics based model development), score management, loss forecasting and MS access based database application development.
