Post-hoc Interpretation via Quantization (PIQ) on ESC-50

This page contains sample interepretations presented in the user study for the PIQ paper. Samples are selected to directly compare PIQ with the original implementation of L2I. Additional samples to further compare PIQ and L2I are selected from ESC50 and presented in the second section.

Results on L2I original implementation mixtures.

Additional samples from ESC50 dataset.

This samples are generated using our implementation of PIQ and L2I, as we were not able to run the original L2I implementation.

Mixture 1. The predicted class by the classifier is CAT.
