I want to classify videos.
After applying dimensionality reduction like PCA, I got this data.
The original data : 25290 x 25
The reduced data : (2~25) x 25
I can't reduce data more 25 dimension.
I want to get more dimension like (50 x 25), (100 x 25), (100 x 25), etc.
However, the dimension is reduced until 25 x 25. Could you explain this problem?
