Abstract
Multivariate approaches used in physics analyses by the High Energy Physics community often combine high-level observables estimated by very complex algorithms. The process to select these variables is usually based on a brute force'' approach, where all available event features are tested for multiple combinations of the algorithm hyperparameters.

In this work, we propose an original method based on the use of a CancelOut layer to select to give as input to a Fully Connected Neural Network. Promising results are obtained in the development of a DNN classifier to select proton-proton collisions where a boosted Higgs boson decay to two $b$-quarks.

Metadata are provided both in "article" format (very similar to INSPIRE) as this helps creating very compact bibliographies which can be beneficial to authors and readers, and in "proceeding" format which is more detailed and complete.
