Three new papers explore the theoretical underpinnings of generalization in deep learning. One paper identifies pre-training as a critical factor for weak-to-strong generalization, demonstrating its emergence through a phase transition during pre-training. Another investigates how sparse connectivity in convolutional networks can improve generalization by processing inputs in low-dimensional patches, offering a principled explanation for their advantage. The third paper presents a non-asymptotic theory explaining generalization by showing how the neural tangent kernel partitions output space, managing signal and noise, and introduces a practical objective that improves training efficiency and performance.
