“…Reinforcement learning [16,17] recently achieved impressive results in many domains of applied research, such as robotics [18], self-driving cars [19], gaming [20]. Coming to high energy physics, it has been mainly suggested for jets reconstruction [21,22] and on-line control system for accelerator machines [23]. In this section we discuss the possibility to train a RL agent to play the role of the devil's advocate (RL Advocate).…”

“…In recent years, different experiments [28,29,30,31] measured a deviation in one of the angular observables of B 0 → K * 0 µ + µ − decays, namely P 5 , in a region of q 2 between 4 and 8 GeV 2 , where q 2 is defined as the di-muon invariant mass squared. In the following, we will use the example of the LHCb measurement of P 5 in the [4.0, 6.0] GeV 2 q 2 bin [28] P 5 = −0.439 ± 0.117 (23) which is found to be higher than the Standard Model value by a factor of 30-40%, depending on the considered theoretical predictions [32,33,34,35].…”

“…Bayesian optimization (and methods based on it), unlike ES, constructs a probabilistic estimate of the unknown functions, in the form of a Gaussian Process (GP), and determines a new point to sample based the fitted function. Neural networks (NN) have been used as surrogate models for magnet control [30] and for simulation-based optimization studies [31]. Neural networks are also being used for uncertainty aware anomaly detection to predict errant beam pulses [32], as virtual diagnostics for 4D tomographic phase space reconstructions [33], for predicting the transverse emittance of space charge dominated beams In Sections IV-B and IV-C we tune several components in this section of the accelerator.…”
