In principle, to nd the optimal code one needs to optimize the tness functionH with respect to all its 2 m s degrees of freedom, the m s entries of the encoder e i and the m s entries of the decoder dj!, taking into account the m conservation relations for the encoder P i e i = 1 and the s conservation relations for the decoder P ! dj! = 1. However, although the degrees of freedom of the encode...
متن کاملA rate-distortion scenario for the emergence and evolution of noisy molecular codes
We discuss, in terms of rate-distortion theory, the fitness of molecular codes as the problem of designing an optimal information channel. The fitness is governed by an interplay between the cost and quality of the channel, which induces smoothness in the code. By incorporating this code fitness into population dynamics models, we suggest that the emergence and evolution of molecular codes may ...

15 صفحه اولRate-Distortion Analysis of Sparse Overcomplete Codes
Transform coding is a popular coding strategy with many desirable properties. The performance of a transform coder relies on the compaction of energy in a small number of coefficients in the transform domain. Most transform coders rely on linear transforms with orthogonal dictionaries, however, linear transforms are limited in that they often only exploit some of the signal structure. For more ...
