Abstract This paper presents an approach to minimize the redundancy of structure existing in wavelet works based on
frame using rough sets theory. The original smcture of work is obtained through time-frequency analysis. Then the
redundant nodes are eliminated in light of dependecy between the output of work and-the nodes in the hidden layers to
optimize the structure of work. Simulation results illustrate the proposed method is simple and effective.
Key words Rough sets: wavelet work: wavelet frame: dependency of attributes
