Beyond Backpropagation
Geoffrey discusses the limitations of backpropagation, emphasizing that it requires a perfect model of the forward system, which he believes the brain does not utilize. He highlights the challenges of applying backpropagation in recurrent networks, particularly when processing video, and points to a lack of evidence supporting its use in biological systems. The conversation invites listeners to consider alternative approaches to neural network training.In this clip
