Abstract:
1. A system for processing signal mixtures, comprising: a processor; a computer readable medium; a signal extraction module, the signal processing module having signal extraction parameters and being configured to receive a signal mixture having a plurality of signals and use the signal extraction parameters to demix the signals to output the plurality of signals as separate signals; a classification module, the classification module being configured to receive the separate signals and recognize words or objects encoded in the separate signals to classify the words or objects encoded in each of the separate signals, with each of the classifications having a confidence level; and an optimization module, the optimization module being configured in a feedback loop to utilize the words or objects encoded in each of the separate signals to adjust the signal extraction parameters to optimize the confidence level of the classifications, thereby optimizing a demixing of the plurality of signals as separate signals.
