Test-Time Memory Evolution: an efficient alternative to Test-Time Training?
In brief
- TTME adapts models without modifying their weights, unlike TTT.
- TTME outperforms TTT on five mathematical tasks in the study.
- Reduces computational costs by 47.7 to 58.4 % in runtime.
Recent *test-time training* (TTT) frameworks enable open-weight large language models to outperform closed models on scientific discovery tasks. However, TTT increases computational costs with online weight updates. A new method, *Test-Time Memory Evolution* (TTME), adapts models without changing their weights. According to the study, TTME outperforms TTT on five mathematical tasks while reducing computational costs by 82.8 to 84.6 % in FLOPs and 47.7 to 58.4 % in runtime.
The evaluation compares TTME and TTT within the same discovery framework, changing only the adaptation method. Results suggest TTME could offer a more efficient solution for large models, though its application to other domains remains to be explored.
