Defines the computation performed at every call. Should be overridden by all subclasses. Although the recipe for forward pass needs to be defined within this function, one ...

Nov 06, 2020 · PositionalEncoding is implemented as a class with a forward () method so it can be called like a PyTorch layer even though it’s really just a function that accepts a 3d tensor, adds a value that contains positional information to the tensor, and returns the result. The forward () method applies dropout internally which is a bit odd.

18.08.2019 · I agree positional encoding should really be implemented and part of the transformer - I'm less concerned that the embedding is separate. In particular, the input shape of the PyTorch transformer is different from other implementations (src is SNE rather than NSE) meaning you have to be very careful using common positional encoding implementations.

Dec 26, 2021 · Abstract. In this work, we investigate the positional encoding methods used in language pre- training (e.g., BERT) and identify several problems in the existing formulations. First, we show that in the absolute positional encoding, the addition operation applied on positional embeddings and word embeddings brings mixed correlations between the ...
