1. A system for processing signal mixtures, comprising: a processor; a computer readable medium; a signal fusion module, the signal fusion module having a set of signal fusion parameters and being configured to receive a plurality of signals and use the signal fusion parameters to fuse the signals to output a fused signal; a classification module, the classification module being configured to receive the fused signal and recognize words or objects encoded in the fused signal to classify the words or objects encoded in the fused signal, with the classification 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 the fused signal to adjust the set of signal fusion parameters to optimize the confidence level of the classification, thereby optimizing a fusion of the plurality of signals as a fused signal.
