15 types of attention mechanisms Attention mechanisms allow models to dynamically focus on specific parts of their input when performing tasks. In our recent article, we discussed Multi-Head Latent Attention (MLA) in detail and now it's time to summarize other existing types of attention. Here is a list of 15 types of attention mechanisms used in AI models: 1. Soft attention (Deterministic attention) -> https://huggingface.co/papers/1409.0473 Assigns a continuous weight distribution over all parts of the input. It produces a weighted sum of the input using attention weights that sum to 1. 2. Hard attention (Stochastic attention) -> https://huggingface.co/papers/1508.04025 Makes a discrete selection of some part of the input to focus on at each step, rather than attending to everything. 3. Self-attention -> https://huggingface.co/papers/1706.03762 Each element in the sequence "looks" at other elements and "decides" how much to borrow from each of them for its new representation. 4. Cross-Attention (Encoder-Decoder attention) -> https://huggingface.co/papers/2104.08771 The queries come from one sequence and the keys/values come from another sequence. It allows a model to combine information from two different sources. 5. Multi-Head Attention (MHA) -> https://huggingface.co/papers/1706.03762 Multiple attention “heads” are run in parallel. The model computes several attention distributions (heads), each with its own set of learned projections of queries, keys, and values. 6. Multi-Head Latent Attention (MLA) -> https://huggingface.co/papers/2405.04434 Extends MHA by incorporating a latent space where attention heads can dynamically learn different latent factors or representations. 7. Memory-Based attention -> https://huggingface.co/papers/1503.08895 Involves an external memory and uses attention to read from and write to this memory. See other types in the comments 👇
