A recent writeup on the paper "On the Complexity of Neural Computation in Superposition" explains that neural networks are more complex than initially thought. Early theories suggested individual neurons represented specific concepts, but researchers discovered "neuron polysemanticity," where one neuron fires for multiple unrelated concepts. The leading explanation is that neural networks utilize high-dimensional spaces and near-orthogonal vectors to represent numerous concepts efficiently, a phenomenon termed representational superposition.
