Train Short, Test Long: Attention with Linear Biases Enables Input . . . We first show that extrapolation can be enabled by simply changing the position representation method, though we find that current methods do not allow for efficient extrapolation We therefore introduce a simpler and more efficient position method, Attention with Linear Biases (ALiBi)
T S , T LONG: ATTENTION WITH LINEAR B E INPUT LENGTH EXTRAPOLATION 3These include the embedding lookup, feedforward sublayer, and softmax layer, which act independently on vector inputs, as well as the attention sublayers, whose parameters do not depend on input length (and which must handle variable-length inputs, e g , due to causal masking)
GitHub - ofirpress attention_with_linear_biases Train Short, Test Long: Attention with Linear Biases (ALiBi) Enables Input Length Extrapolation This repository contains the ALiBi code and models for our ICLR 2022 paper Train Short, Test Long
Attention with Linear Biases (ALiBi) This is an implementation of Attention with Linear Biases (ALiBi) from the paper Train Short, Test Long: Attention with Linear Biases Enables Input Length Extrapolation This replaces positional encodings with biases added to attention scores (attention logits, before the softmax)
Train Short, Test Long: Attention with Linear Biases Enables Input . . . Attention with Linear Biases (ALiBi) is a positional encoding method that adds a linear bias to the attention scores based on the relative positions of tokens This approach encourages the model to focus more on nearby tokens, which is beneficial for capturing local dependencies
Train Short, Test Long: Attention with Linear Biases Enables Input . . . We first show that extrapolation can be enabled by simply changing the position representation method, though we find that current methods do not allow for efficient extrapolation We therefore introduce a simpler and more efficient position method, Attention with Linear Biases (ALiBi)
Train Short, Test Long: Attention with Linear Biases Enables Input . . . The paper addresses the extrapolation problem where a test sequence longer than training sequences is given and proposes Attention with Linear Biases (ALiBi) that adds a penalty linear to the distance between a query and a key to the attention scores
PyTorch implementation of Train Short, Test Long: Attention with Linear . . . We introduce a simple and efficient method, Attention with Linear Biases (ALiBi), that allows for extrapolation ALiBi does not add positional embeddings to the word embeddings; instead, it biases the query-key attention scores with a term that is proportional to their distance
