Polynomial model

Additive smoothing

Unsupervised anomaly detection w/ MNAD

MNAD paper MNAD repository

My memory implementation might differ a little from official MNAD implementation. However, it is based on MNAD paper and official repository. I've used all the loss functions as MNAD paper suggested (reconstruction, compactness and separatness loss)

I've tried to estimate loss threshold twice: for train data (red line) and for test data (green line). As we can see, train estimated threshold is close to optimal

Latent space visualization with PCA, SVD and t-SNE decomposition. PCA and t-SNE show separability.
