OR-Gate: A Noisy Label Filtering Method for Speaker Verification
share
The deep learning models used for speaker verification are heavily dependent on large-scale data and correct labels. However, noisy (wrong) labels often occur, which deteriorates the system's performance. Unfortunately, there are relatively few studies in this area. In this paper, we propose a method to gradually filter noisy labels out at the training stage. We compare the network predictions at different training epochs with ground-truth labels, and select reliable (considered correct) labels by using the OR gate mechanism like that in logic circuits. Therefore, our proposed method is named as OR-Gate. We experimentally demonstrated that the OR-Gate can effectively filter noisy labels out and has excellent performance.
