WebApr 11, 2024 · In the encoder, a graph attention module is introduced after the PANNs to learn contextual association (i.e. the dependency among the audio features over different time frames) through an adjacency graph, and a top- k mask is used to mitigate the interference from noisy nodes. The learnt contextual association leads to a more … WebNov 10, 2024 · Masked LM (MLM) Before feeding word sequences into BERT, 15% of the words in each sequence are replaced with a [MASK] token. The model then attempts to predict the original value of the masked words, based on the context provided by the other, non-masked, words in the sequence. In technical terms, the prediction of the output …
