The proposed Logit Arithmetic Reweighting Approach (LARA) enhances In-Context Learning (ICL) for Large Language Models (LLMs), allowing them to adapt to new tasks by leveraging task-specific examples without updating model parameters. This approach divides long input demonstrations into parallelizable shorter inputs, reducing memory requirements, and then aggregates information by reweighting logits via a non-gradient optimization method. The variant Binary LARA (B-LARA) constrains weights to binary values, simplifying the search space and reducing memory usage. Experimental results on BBH and MMLU demonstrate that LARA and B-LARA outperform baseline methods in both accuracy and memory efficiency.

Large Language Models are getting smarter! Researchers found a way to make them learn new things without needing to update their rules. They did this by breaking down big examples into smaller pieces, so the model doesn’t get too confused. This helps the model remember things better and use less memory. The team even came up with a special version that makes it easier for the model to figure out what’s important. It works really well on lots of different tasks!
