Web18 Mar 2024 · In linear models, Lasso (or ℓ 1 -regularized) regression assigns zero weights to the most irrelevant or redundant features, and is widely used in data science. However … WebThey introduce LassoNet, a neural network framework with global feature selection. The method extends lasso regression and its feature sparsity to feed-forward neural network. In experiment, LassoNet selects the most informative pixels on a subset of MNIST dataset, and classifies the original images with high accuracy.

"WebThe core idea of LassoNet is to use a hierarchical penalty on all input features which have no (direct) linear effect on the output. Hence, the first layer of the model should be linear as the weight of this layer are penalized columnwise. Define a PyTorch network G (i.e. some class inheriting from torch.nn.Module) with arbitrary architecture ... " - Lassonet jmlr
