LM-Infinite Innovations
- Meta AI's LM-Infinite offers two primary innovations: a lambda-shaped attention mask and bounded relative distance during attention.
- These innovations improve performance over long context windows, especially those exceeding training lengths, addressing the "dilution" issue.
Warehouse vs. Closet Analogy
- David Shapiro uses the analogy of a cluttered warehouse versus a tidy closet to explain how LM-Infinite improves memory management.
- The constrained "working memory" by LM-Infinite leads to better performance and prevents dilution.
Human Memory Analogy
- David Shapiro compares language model memory to human memory when reading a long novel series.
- The ability to constrain working memory and recall specific details is crucial for both.
