⌛️ The Surprising Effectiveness of Test-Time Training for Abstract Reasoning

This paper examines how test-time training (TTT) can enhance the abstract reasoning abilities of large language models (LLMs). TTT, which updates model parameters during inference, significantly improves performance on the Abstraction and Reasoning Corpus (ARC) benchmark. Key factors for effective TTT include initial fine-tuning, auxiliary tasks, and instance-specific training. The approach achieves state-of-the-art results on ARC, even matching human averages with program synthesis. This study suggests that dedicating computation at test time, rather than relying on symbolic components, may be essential for complex reasoning tasks.
