Information processing using the sparsity of information has been actively studied such as compressed sensing.
In this study, we discuss sparse information processing from the viewpoint of lossy compression.
The choice of a basis is important for lossy compression.
Overcomplete bases are expected to be useful to compress information because they include more candidates to express it.
We analyze the rate-distortion relation of overcomplete basis compression in a statistical mechanical manner and show they outperform a naive random projection approach.
We also discuss some algorithms to realize the rate-distortion relation of overcomplete basis compression. |
