New convex reformulation for deep linear neural networks unveiled

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a novel method to reformulate the training problem of deep linear neural networks into an exact convex problem. This is achieved by lifting the network's parameters into a higher-dimensional space, specifically over a generalized completely positive cone. The resulting convex formulation shares the same optimal value as the original non-convex problem, with the non-convexity encapsulated within the cone constraint. This approach simplifies the problem by making the lifted dimension dependent only on input and output dimensions, independent of network depth or data size, and incorporates bottleneck width through scalar constraints.

    Exact Convex Reformulations of Linear Neural Networks via Completely Positive Lifting

    arXiv:2605.17692v2 Announce Type: replace Abstract: We show that the training problem of a deep linear neural network under the squared loss admits an exact convex reformulation in a lifted space over a generalized completely positive cone. The reformulation has the same optimal …
