largeFiles
.
Statistic the prior probabilities of categories, and posterior probabilities between each two categories.
- The
prob_analysis.py
script will compute the probability of categories, it will also compute the posterior probability between each two categories.
Use PCA and TSNE method to project the samples into regularized 3D space, the features are their categories vector in hot-encoding format.
- The
category_space_analysis.py
script will do the computation.
