MSE loss hinders superposition in neural networks, researchers find

Researchers have demonstrated that Mean Squared Error (MSE) loss is ineffective for training neural networks to encode features in superposition, a technique where more features are represented than there are neurons. This finding, supported by mathematical analysis and experimental evidence, suggests that MSE loss does not incentivize the network to utilize superposition. The authors recommend using alternative loss functions, such as logarithmic loss, when aiming for superposition in toy models or other applications. AI

IMPACT Using appropriate loss functions is crucial for developing more efficient and capable neural network architectures.
