WebMay 3, 2024 · Looking at an alternative implementation of the BERT model, the positional embedding is a static transformation. This also seems to be the conventional way of doing the positional encoding in a transformer model. Looking at the alternative implementation it uses the sine and cosine function to encode interleaved pairs in the input. WebApr 24, 2024 · The diagram above shows the overview of the Transformer model. The inputs to the encoder will be the English sentence, and the ‘Outputs’ entering the decoder will be the French sentence. In effect, there are five processes we need to understand to implement this model: Embedding the inputs. The Positional Encodings.
