Experiment-1:

Frequent itemset: an itemset X is called frequent for database 𝐷 if and only if it is contained in more than min support many transactions: support(X) >= min support

1. Download the data set from here: groceries.csv 

2. Write a Map-reduce program to find 1-frequent item set with 25% min support 

3. Write a Map-Reduce program to find 2-frequent item set with 23% min support

4. Write a Map-reduce program to find 3-frequent item set with 20% min support

Experiment-2:

1.Download MovieLens data set  

2. Use ratings.csv file , Write a Map-Reduce Program to find the average rating of movies . Where average rating of movie X is defined as  =  (sum of ratings of movie X/ total number of ratings of X)      (not a great formula, come up with your own)
