(Data Mining) proove backpropagation algorithm.
Solution:




This question is for frequent pattern mining algorithm Apriori and closed pattern mining algorithm like CLOSET. Implement Apriori algorithm to mine frequent pattern from a transaction dataset Implement an algorithm to mine closed frequent pattern from the same dataset. You can either write a code to extract closed patterns from the result that you got in Part 1 or code CLOSET. Input Format The input dataset is a transaction dataset. The first line of the input corresponds to the minimum...
Data Mining: Explain why decision tree algorithm based on impurity measures such as entropy and Gini index tends to favor attributes with larger number of distinct values. How would you overcome this problem?
This is a data mining course question. We are using Data Mining: Concepts and Techniques third edition. Please help with the following assignment.

Question in Data mining :
Apply Apriori algorithm on the grocery store example with support threshold s = 33.34% and confidence threshold c = 60%, where H, B, K, C and P are different items purchased by customers. Show all final frequent itemsets. Specify the association rules that are generated. Show final association rules sorted by confidence. Represent the transactions as graph.
