Gradient Descent Mimics Perceptron Algorithm in Neural Networks

Researchers have demonstrated that gradient descent steps in neural networks trained with logistic loss can be simplified to resemble generalized perceptron algorithms. This new perspective, using classical linear algebra, reveals how the nonlinearity in two-layer models can achieve faster iteration complexity than linear models. The findings offer a theoretical explanation for the implicit acceleration observed in neural network optimization and are supported by numerical experiments. AI
