New Theory on Neural Network Rank Lifting Published

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a new theoretical framework for understanding rank lifting in neural networks, focusing on the width required for a randomly initialized hidden layer to achieve this property. The study provides a dimension-free bound for positively homogeneous non-polynomial activations, significantly improving upon previous general-dimensional guarantees. This work unifies and generalizes stable rank lifting guarantees for various activations, employing techniques like matrix concentration and kernel analysis to establish bounds for stable rank lifting.

    Dimension-Free Rank Lifting from Random Hyperplane Arrangements

    arXiv:2609.39855v1 Announce Type: new Abstract: We study the width required for a randomly initialized hidden layer of a neural network to achieve rank lifting. Namely, given a dataset $X \in \mathbb{R}^{m \times d}$ of $m$, $d$-dimensional input vectors separated by an angle of …
