A Novel Signal Separation Method Based on Improved Sparse Non-Negative Matrix Factorization
In order to separate and extract compound fault features of a vibration signal from a single channel, a novel signal separation method is proposed based on improved sparse non-negative matrix factorization (SNMF). In view of the traditional SNMF failure to perform well in the underdetermined blind s...
