Alpha-rectifying Frames:
This repository contains routines related to the injectivity of ReLU-layers and
-
polytope bias estimations (PBE) for different input data domains:
given a collection of vectors (e.g. row vectors of a weight matrix), the PBE gives a bias vector
$\alpha^\mathbb{K}$ such that any ReLU-layer with bias$b\leq\alpha^\mathbb{B}$ is injective on$K$ - reconstruction formulas for injective ReLU-layers
