Gpt positional encoding
WebApr 7, 2024 · Positional Encoding. Because self-attention operation is permutation invariant, it is important to use proper positional encodingto provide order information to the model. The positional encoding $\mathbf{P} \in \mathbb{R}^{L \times d}$ has the same dimension as the input embedding, so it can be added on the input directly.

WebApr 10, 2024 · The encoding is performed by mapping time step t to the same randomized lookup table during both training and prediction. This is different than standard self-attention which uses cosine and sine functions to capture the position of words.

Websuch as GPT-3, typically require some form of positional encoding, such as positional em-beddings. However, we show that LMs with-out any explicit positional encoding are still competitive with standard models, and that this phenomenon is robust across different datasets, model sizes, and sequence lengths.
