fast-weight-networks-1992-equivalent-linear-transformer

Summary

The 1992 fast-weight network and the 2017 linear transformer turn out to be the same mathematical object written in different notation, meaning the later architecture was not a genuinely new idea but a rediscovery of a connection already worked out more than two decades earlier. This matters because it reframes a widely cited 2017 contribution as a restatement of prior work and gives the 1992 formulation a stronger claim on historical priority.
