Notes {{word-count}}


Key points:

In Machine Learning, instead of defining the input -> output relationship by hand, we learn a program that acquires the relationship from data.

Tom Mitchell's definition

A computer program is said to learn from experience EE with respect to some class of tasks TT and performance measure PP, if its performance at tasks in TT, as measured by PP, improves with experience EE.

The Machine Learning method for solving any problem ever.

Define your model class.

Model class refers to the the set of possible programs。

Define your Loss Function.

Loss Function measures if one model in the model class is better than another.

Define your Optimizer.

The optimizer searches the model class to find the model that minimizes the Loss Function.

Run it on a GPU.
