Haha, there are ONLY up to 69 of them and it is not hard to make top 75, lol. I would like to see them all.

Over the time, I would like to collect them and rank them (by personal view only now) hopefully according to some “objective metric”.

1. But, I like to rank Titus Brown’s site above Dave Tang’s. No offense to Dave, it it my personal opinion that I find Titus’ contains higher quality of work. Sorry Dave!. Titus’ home page has an interesting name
2. Here is one from Dave Tang

Here, an old topic but keeps coming to me — machine learning. Java? Python? or R?

Let’s focus on some readings.

A guy posts decision making algorithm with implementation in python, 
of course!

He does not reply why data link is broken, which can be easily found 
here at kaggle competition site.

Here is a very simple tutorial about decision tree algorithm.

Another example here should be enough

Found another quite basic explanation

More on decision tree — iterative preorder traversal

Here is the first example

Decision Tree implementation

A simple python example.

Another guy provides smile  (Statistical Machine Intelligence and 
Learning Engine) package implemented in Java
