Sparse Coding Models Can Exhibit Decreasing Sparseness while Learning Sparse Codes for Natural Images
The sparse coding hypothesis has enjoyed much success in predicting response properties of simple cells in primary visual cortex (V1) based solely on the statistics of natural scenes. In typical sparse coding models, model neuron activities and receptive fields are optimized to accurately represent...
