Thnks for the Replay sir, actually i am doing clustering for gathering similar king of document in same cluster as much as possible. i can see from output file by cluster dump by observing top term. i also figure out that by varying Distance Measure Technique. it differs. but i want some mathematical prof that it is better then other technique. so for that i need to calculate Entropy and pureness of cluster. but i am not able to find any command in mahout which can give me entropy as a result. i found Entropy.java under mahout common math statistic package. but i don't what should i give it as input so that i can find entropy or other parameter. so i can find how much cluster is good or bed.
