What kind of memory?

Separate working context, recurrent state, learned parameters and persistent storage.

Definition

Context contains information supplied for a computation. A recurrent network propagates state across steps. External storage can retain documents and retrieve useful ones for a request. These mechanisms have different capacities and retention guarantees.

Equation

hₜ = fθ(hₜ₋₁, xₜ)

hₜ is state at step t, xₜ the current input and θ the parameters. Recurrent state is neither a document database nor, by itself, permanent memory.

Assumptions and notation

hₜ is state at step t, xₜ the current input and θ the parameters. Recurrent state is neither a document database nor, by itself, permanent memory.

Limits of interpretation

A file added to one conversation is not guaranteed to appear in another. Persistence depends on the product and settings; retrieving a document need not retrain the model.
