Despite their impressive performance, Deep Neural Networks (DNNs) typically underperform Gradient Boosting Trees (GBTs) on many tabular-dataset learning tasks. We propose that applying a different regularization coefficient to each weight might boost the performance of DNNs by allowing them to make more use of the more relevant inputs. However, this will lead to an intractable number of hyperparameters. Here, we introduce Regularization Learning Networks (RLNs), which overcome this challenge by introducing an efficient hyperparameter tuning scheme which minimizes a new Counterfactual Loss. Our results show that RLNs significantly improve DNNs on tabular datasets, and achieve comparable results to GBTs, with the best performance achieved with an ensemble that combines GBTs and RLNs. RLNs produce extremely sparse networks, eliminating up to 99.8% of the network edges and 82% of the input features, thus providing more interpretable models and reveal the importance that the network assigns to different inputs. RLNs could efficiently learn a single network in datasets that comprise both tabular and unstructured data, such as in the setting of medical imaging accompanied by electronic health records.

Summary This work develops Regularization Learning Networks (RLN), an approach to learn varying levels of regularization for different network weights. Regularization levels for (D)NN are usually a global hyper-parameter, optimized via CV for the whole network. The author point out that figuring different levels or regularization for different features is appealing especially for data where features are of different "type" with some possibly highly important while others not and the transition between those is more striking than common in say structured images. Good examples are smaller tabular data of expression, EHR where DL commonly underperforms. The CV approach without a direct target function to optimize does not scale for optimizing each weight separately.
