June 14

I have to admit I feel like slacking today. Not much work is done, what I have done is simply test the program for a couple of more times. I want to implement a hierarchical clustering but things got a bit complicated. I hope to finish it by tomorrow.

I have shown my work to Edward. He didn't comment much but I think he is not indeed satisfied, and I expect much improvement work has to be done. Leave my work for tomorrow anyway.
