WebAug 15, 2024 · Pytorch’s transformer library is based on the idea of “positional encoding”, which is a way of representing the position of an element in a vector. Positional encoding is a key idea in many transformer models, and it enables the model to learn the relative position of two elements in a sequence. WebNov 5, 2024 · In the Automatic Speech Recognition field, 1D convolution is used as a replacement for relative position encoding in Transformers. The data flow would then be input --> pos_embedding=Conv1D(input) --> input += pos_embedding --> Self-Attention. Facebook's Wav2Vec 2.0 utilized this variant of position encoding and got SOTA results.
