Light CNN (LCNN) is CNN based model which was proposed in Interspeech 2019 by STC teams and state of the art of ASVspoof2019.
LCNN is featured by max feature mapping function (MFM). MFM is an alternative of ReLU to suppress low-activation neurons in each layer. MFM contribute to make LCNN lighter and more efficient than CNN with ReLU.

In this project, LCNN is trained with ASVspoof2019 PA dataset. As a speech feature, I used spectrograms that extracted by using STFT or CQT.
