The passage around this formula
…feature, distorting reconstruction in a way that has nothing to do with how many features are active. Rajamanoharan and colleagues introduced JumpReLU, a thresholded activation function with a learned per-feature cutoff trained through a straight-through gradient estimator, which lets the objective penalise the true count of active features, f(x) , directly rather than through the proxy, and reported state-of-the-art reconstruction fidelity at matched sparsity against both the earlier…
