Dear lord... "machine learning algorithms" you might just as well say you use computers given how broad this is. Even the most closed things have their bases published, like the basic page ranking algorithm used by Google.

What is your training set for this ? How large is it ? Did you buy it or construct it yourself ? What methods did you use to train and test the secret machine learning methods you are using ? Is anything of you doing new, or is it just the typical SVM, some trivial decisions trees or what ? There are so many questions to be asked here.. and none of them will get answered, because it is so secret... It is really a shame that people build such closed services over bitcoin and, even worse, people use that.
