Abstract: A system may receive input data corresponding to classes. The system may determine a value of a parameter for a digital signal processing (DSP) component based on the input data. The DSP component may control digital signal processing of the input data to generate features for a machine learning model to identify the classes. The value may be determined from a set of candidate values based on applying an optimization function associated with the parameter. In some implementations, the optimization function may measure a distance between vectors calculated by a DSP function implemented by the DSP component. In some implementations, the optimization function may compare spectral energies at multiple frequencies calculated by a DSP function implemented by the DSP component.
