Systems and methods for speaker diarization

A computing device, comprising:

• one or more processors;
• memory;
• and
• one or more programs stored in the memory and configured for execution by the one or more processors, the one or more programs comprising instructions for:
• obtaining an audio recording;
• generating an embedding signal from the audio recording;
• factoring the embedding signal to obtain a basis matrix and an activation matrix, including obtaining a sparse optimization of the embedding signal by minimizing a norm corresponding to the factored embedding signal;
• and
• generating a speaker log for the audio recording based on the sparse optimization of the embedding signal.
