(Master of Information Science) Pattern Recognition
-
Increasing the number of Features makes it easier to draw dividing lines between classes.
- However, the reason it becomes easier is that the number of patterns for dividing lines increases as the dimension increases.
- Many of these patterns cannot handle unknown data.
-
Therefore, when actually tested with test data, the results decrease as the dimension increases.

(blu3mo) Similar to Overfitting, this phenomenon also occurs with the number of dimensions.
- There aren’t many common points between the phenomena themselves. #Machine Learning
