Leveraging-Induced Polarization for Drug Discovery: Efficient IC50 Prediction Using Minimal Features Open
Here, we use the frequency of the atomic hybridizations (s, sp, sp2, and sp3) of each atom type (H, C, N, O, S, etc.) within a molecule to predict the IC50s of drug-like molecules, focusing on compounds targeting the Thrombin, Estrogen Rec…

Maximum Entropy Exploration in Contextual Bandits with Neural Networks and Energy Based Models Open
Contextual bandits can solve a huge range of real-world problems. However, current popular algorithms to solve them either rely on linear models or unreliable uncertainty estimation in non-linear models, which are required to deal with the…

A survey and taxonomy of loss functions in machine learning Open
Most state-of-the-art machine learning techniques revolve around the optimisation of loss functions. Defining appropriate loss functions is therefore critical to successfully solving problems in this field. In this survey, we present a com…

Search for Heavy Stable Charged Particles in the CMS Experiment using the RPC Phase II upgraded detectors Open
Several theoretical models inspired by the idea of supersymmetry (SUSY) accommodate the possibility of Heavy Stable Charged Particles (HSCPs). The Phase II upgrade of the CMS-RPC system will allow the trigger and identification of this kin…

RPC radiation background simulations for the high luminosity phase in the CMS experiment Open
The high luminosity expected from the HL-LHC will be a challenge for the CMS detector. The increased rate of particles coming from the collisions and the radioactivity induced in the detector material could cause significant damage and res…

High voltage calibration method for the CMS RPC detector Open
The Resistive Plate Chambers (RPC) are used for muon triggers in the CMS experiment. To calibrate the high voltage working-points (WP) and identify degraded detectors due to radiation or chemical damage, a high voltage scan has been perfor…

Longevity studies on the CMS-RPC system Open
In the next decades, the Large Hadron Collider (LHC) will run at very high luminosity (HL-LHC) 5 x 10(34) cm(-2) s(-1), factor five more than the nominal LHC luminosity. During this period the CMS RPC system will be subjected to high backg…
