Linear Mappings have a Memory

Note about the memory effects seen when you use linear mappings as associative memory.
Prior memories can hang around for a long time, including random memories programmed in by random initialization.
That’s because storing new memories only slightly damages prior memories, then it’s just a hit count of how many new memory training examples have damaged a prior memory and by how much.

The online linear regression people already know the math of that.
Perhaps though are less aware of the mechanistic interpretations.
One application is concatenated context selected linear mappings: https://sciencelimelight.blogspot.com/2026/09/an-introduction-to-concatenated-context.html

A person with a lot of knowledge in the linear area is Andrew Saxe. And in one paper he discovered an adjacent system to CCSLM: https://arxiv.org/pdf/2207.10430
