features for something like speech recognition so what what CPC is trying to do is its trying to make predictions in the latent space at the levels of phonemes instead of variety of audio waveforms so as you keep processing these are your signals the information becomes more more semantic and so if you're trying to predict something that's not overlapping in terms of a target if you're trying to predict your target that's reason to be a few time steps ahead you're trying to go more towards these slow varying phonemes that
