The Interpretable Dictionary in Sparse Coding

no code implementations24 Nov 2020 Edward Kim, Connor Onweller, Andrew O'Brien, Kathleen Mccoy

Artificial neural networks (ANNs), specifically deep learning networks, have often been labeled as black boxes due to the fact that the internal representation of the data is not easily interpretable.
