SKIM
A closed-form parameter writing method that uses diverse self-generated questions as keys and conversation content as values, writing them into the parameters of a frozen language model to achieve conversational recall without external storage.
Timeline (last 90 days)
SKIM (Self-Keyed In-Parameter Memorization) is a closed-form method that writes conversation content directly into the parameters of a frozen language model, enabling the model to answer questions about past conversations using its parameters alone.
The core mechanism of SKIM is to automatically generate a large number of diverse questions for each dialogue round as "keys" written into the parameters, which are used to later retrieve the content of that dialogue round.
The writing process of SKIM is closed-form and involves no gradient updates or additional training, and the model remains frozen.
The study evaluated SKIM on five language models, and the results show that it can recall most stored dialogue rounds from subsequent user questions, with answers coming entirely from the model parameters.
The closed-form writing of SKIM means that parameter updates are given in one shot by matrix operations, requiring neither backpropagation nor saving optimizer states; the cost is that the capacity and precision of writing are limited by the form and numerical stability of the chosen closed-form solution.
The difficulty of SKIM lies in that written content accumulates over time, and new and old writes may overwrite or interfere with each other.
