A new paper analyzes the effectiveness of Gated Linear Units (GLU) in large language models, finding that they improve training speed by reshaping the neural tangent kernel (NTK) spectrum. Researchers observed that GLU structures lead to a smaller condition number and faster convergence, a phenomenon sometimes resulting in loss-crossing between GLU and non-GLU models. However, the study also indicated that GLU's benefit is primarily in optimization acceleration rather than reducing the generalization gap. AI
