Researchers have found that restricting what a shared language model can see in its environment improves its ability to generalize and solve complex tasks. In an experiment, they created 'societies' of four-cell systems sharing a pre-trained language model and adapter, but with varying levels of evidence visibility. They found that when the model could only communicate through two continuous vectors, it performed better than when it had full access to the input. This suggests that limiting what the model sees can help it learn more generalizable solutions. --- Why it matters: This study has implications for the development of language models and their applications in areas like natural language processing and computer vision. By understanding how restricted evidence visibility affects a model's performance, researchers can design more effective systems that balance communication and learning.
