Researchers develop learned task vectors for improved in-context learning in LLMs

Researchers have developed a new method for training "Learned Task Vectors" (LTVs) that improve the in-context learning capabilities of large language models. Unlike previous methods that extracted task vectors, LTVs are directly trained and show superior performance and flexibility across different model layers and positions. The study also provides mechanistic insights, revealing that task vectors primarily influence predictions through specific attention heads and largely propagate linearly through the model's layers.
