A new research paper reveals that standard supervised training methods, particularly backpropagation, can rapidly degrade the alignment of artificial neural networks with the early visual cortex of the human brain. This degradation occurs within a single training epoch, suggesting that untrained networks may capture low-level visual statistics more effectively due to inherent inductive biases. Alternative learning rules like predictive coding and spike-timing-dependent plasticity show less severe degradation, preserving more brain-like structure in early visual representations. AI
IMPACT Suggests current training methods may hinder AI models from achieving optimal representational similarity with biological vision systems.
