Researchers have published a paper detailing the incremental learning process in mildly overparameterized ReLU networks trained on orthogonal data. The study proves that as initialization scale approaches zero, the gradient flow converges to a saddle-to-saddle jump process, leading to new neurons activating sequentially. This phenomenon allows networks to interpolate training data efficiently, with a width proportional to the logarithm of the number of samples. The research also establishes a novel implicit bias, showing the learned interpolator's squared L2-norm scales with the square root of the number of samples, closely approximating the minimal L2-norm interpolator.
