Researchers have investigated why Gated Linear Units (GLU) are superior to non-GLU structures in large language models. Their analysis in the neural tangent kernel regime indicates that GLU reshapes the NTK spectrum, resulting in a smaller condition number and faster convergence. While GLU appears to accelerate optimization, empirical observations suggest it has a limited effect on reducing the generalization gap in models like ViT and GPT-2. AI
