Compressing long contexts into fixed-size states
Avoid compressing very long sequences into fixed-size states, as this loses rich information needed for tasks like document understanding.
Employ architectures like Titans that combine speed with the ability to handle massive contexts by actively updating memory, or use methods that retain richer information.
Compressing extremely long contexts into a fixed-size state, as done by some efficient RNNs and SSMs.
Fixed-size compression cannot adequately capture the rich information present in very long sequences, limiting the model's understanding and accuracy for complex tasks.
Avoid compressing long sequences into fixed-size states, as this leads to information loss. Instead, use architectures that can actively update and manage memory, preserving the rich details necessary for tasks like full-document understanding or genomic analysis.
