A new paper identifies a significant disconnect between the diversification of forward dynamics in neural network architectures and the relative stagnation of their learning mechanisms. While models have evolved to incorporate complex state dynamics, long contexts, and continuous time, training methods largely remain centered around backpropagation and its variants. The authors propose a taxonomy to analyze this gap across various neural model families, highlighting the need for better alignment between state dynamics, credit assignment, and computational substrates to advance neural computation.
