Keras position embedding

Web6 jun. 2024 · A positional embedding is similar to a word embedding. Except it is the position in the sentence is used as the index, rather than the one hot encoding. A positional encoding is not learned but a chosen mathematical function. $\mathbb{N}\rightarrow\mathbb{R}^n$. Share. Cite.

WebTaking excerpts from the video, let us try understanding the “sin” part of the formula to compute the position embeddings: Here “pos” refers to the position of the “word” in the sequence. P0 refers to the position embedding of the first word; “d” means the size of the word/token embedding. In this example d=5. WebPosition embedding layers in Keras.
