Why MSE

Duke_Wisdom 2025. 3. 30. 20:08

In MSE, we use the square of differences (hence "Square" in Mean Square Error).
This means that the number of classifications builds the dimensions of our space. 
In this n-dimensional space, MSE measures the squared Euclidean distance between predicts vectors and label vectors.

This actually applies the Pythagorean theorem extended to n dimensions.

 

추론값의 벡터와, 정답 값의 벡터가 있다면
그 차이의 벡터를 유클리드 거리로 표현하는 것이 MSE가 된다.
