In the vanilla transformer, positional encodings are added before the first MHSA block model. Let’s start by clarifying this: positional embeddings are notrelated to the sinusoidal positional encodings. It’s highly similar to word or patch embeddings, but here we embed the position. Moreover, positional embeddings … See more If the PE are not inside the MHSA block, they have to be added to the input representation, as we saw. The main concern is that they … See more It is often the case that additional positional info is added to the query (Q) representation in the MSHA block. There are two main approaches here: 1. Absolute PE 2. Relative PE Absolute positions: every input … See more However, when you try to implement relative PE, you will have a shape mismatch. Remember that the attention matrix is tokens×tokenstokens \times tokenstokens×tokens … See more Absolute PE implementation is pretty straight forward. We initialize a trainable component and multiply it with the query qqq at each forward pass. It will be added to the QKTQ … See more WebMar 1, 2024 · It seems that in the music transformer paper, the authors dropped the additional relative positional embedding that corresponds to the value term and focus only on the key component. In other words, the authors only focus on (1), not (2).
