Description
Experience Level: Entry
Create a star schema (two fact tables), create the tables using postgreSQL, Write and run 6 SQL queries.
* search for at least 25 different datasets, then apply them using WEKA software on Decision tree (J48), Random Forest, and K-NN (IBk) (with K taking the value of 1 up to the number of class labels in the dataset). After this, Compare the performance of the applied techniques in terms of accuracy.
Analyse the results with regard to the dataset properties.
* Apply the following clustering techniques using the WEKA software on only 10 of the datasets you selected in task 1:
(1) K-means,
(2) Agglomeration method
Remove the class attribute before applying the above clustering methods. Once you have applied the clustering techniques on all the datasets, it is required to accomplish the following tasks:
