The Sinusoidal-based encoding does not require training, thus does not add additional parameters to the model.

WebJul 25, 2024 · What is the purpose of positional embeddings? In transformers (BERT included) the only interaction between the different tokens is done via self-attention layers. If you look closely at the mathematical operation implemented by these layers you will notice that these layers are permutation equivariant: That is, the representation of WebJan 6, 2024 · To understand the above expression, let’s take an example of the phrase “I am a robot,” with n=100 and d=4. The following table shows the positional encoding matrix for this phrase. In fact, the positional encoding matrix would be the same for any four-letter phrase with n=100 and d=4.
