Today I want to describe some ideas about measure quality of learning.
First of all I want to point areas where you can apply those measurements. It can be in three areas:
For setting funtional during learning
For picking hyperparameters
For evaluation of ready made model
Another way can be combination. You can measure quality during learning with one measurement, but final model you can analyze with other measurement.
So, let's start with most common formula: mean squared error:
In words it reads the following: difference between prognozed value and desired value, squared, summed and finally averaged.
MSE has following featues:
Easily minimizable … more
