New research details local minima in neural network loss landscapes

By PulseAugur Editorial · [1 sources] ·

Researchers have detailed the loss landscape of two-layer ReLU neural networks, revealing that local minima can be precisely characterized by summary statistics. This work establishes a connection between these minima and the dynamics of one-pass Stochastic Gradient Descent (SGD), indicating a hierarchical organization of minima. The study suggests that in overparameterized scenarios, global minima become more accessible, leading to reduced convergence on spurious solutions. AI

IMPACT Provides a deeper theoretical understanding of neural network training dynamics, potentially informing future optimization techniques.

    Sharp description of local minima in the loss landscape of high-dimensional two-layer ReLU neural networks

    arXiv:2604.09412v2 Announce Type: replace Abstract: We study the population loss landscape of two-layer ReLU networks of the form $\sum_{k=1}^K \mathrm{ReLU}(w_k^\top x)$ in a realisable teacher-student setting with Gaussian covariates. We show that local minima admit an exact lo…
