Summary

Meta unveils a groundbreaking AI framework, MTTT, that enables models to learn how to learn at test time, removing the need for human-designed self-supervised tasks and outperforming linear attention on long sequences while maintaining linear complexity.

Key Points

  • Meta researchers develop a new AI framework called MTTT that allows models to learn how to learn at test time
  • MTTT removes human ingenuity from designing self-supervised tasks by parameterizing the task itself
  • MTTT with an MLP feature extractor outperforms linear attention on long sequences while retaining linear complexity
