Exploring Segments

Demo:

ISQS6347-5.Pattern_Discovery.Explore_Segments

Hands-on-4:

1) Plot the 3-D view of the clustering outcomes

2) Check a segment in the 3-D chart via a histogram chart.

6 min

10 min

The 3-D diagram looks pretty and informative, but takes more time for us to understand it.

2-2

Profiling Segments

Demo:

ISQS6347-5.Pattern_Discovery.Profiling_Segments

Hands-on-5:

1) Add and run a Segment Profile node connected to the Cluster node.

2) Study the results.

(A screenshot will be submitted together with the next hands-on exercise)

SOM/Kohonen Clustering

Demo:

ISQS6347-8.Pattern_Discovery.SOM_Clustering

Hands-on-6:

1) Connect a SOM/Kohonen node to the Filter node and connect a Segment Profile node after it.

2) Run the nodes one by one and study the results.

The introduction of SOM/Kononen method in the course notes is limited, but you can always find enriched online materials.

 

Deliverable:

The screenshots Hands-on clustering results – must include the information showing your user ID at the bottom line of the SAS EM panel.

This is to show students’ participation in the class meeting.
