Researchers have demonstrated that a single neuron, when trained with autoregressive Chain-of-Thought (CoT) supervision, can simulate any feedforward circuit with the same activation function. This finding suggests that even simple neural structures can achieve significant computational power. The study, which connects to Sidon sets in additive combinatorics, shows that autoregressive threshold neurons can simulate polynomial-time Turing machines and are efficiently learnable. As a practical demonstration, a single autoregressive ReLU neuron was trained to mimic a neural network on the CIFAR-10 dataset with notable accuracy. AI
IMPACT Suggests that simpler neural architectures might achieve complex computational tasks with appropriate training methods.
