Testing machine learning algorithms

Tests are the only way to estimate the quality of a machine learning algorithm in practice. In order to prove your algorithm is usable, you need to design good tests. To design test you should collect the data and split them into the train set and the test set.Machine learning theorists say that the train and the test sets should come from the single probability distribution (unless they are talking about transfer learning or some kinds of on-line...

i want to add some charm to our front porch....the first thing that would make it cuter would be wonderful ferns and great potted plants by the door, but considering it's january, i am starting by thinking about the front door.
