Machine-Learnt parametrizations for the Ultra-Fast Simulation of the LHCb detector /LHCb collaboration
High-quality parametrizations of the response of the LHCb experiment to traversing charged particles are being developed using Machine Learning algorithms including Gradient Boosting Decision Trees and Deep Neural Networks trained in adversarial configuration. The trained models are intended to replace parts of the detector simulation to reduce the CPU hours requested to produce large simulated samples. [...]

Comparison of particle selection algorithms for the LHCb Upgrade /LHCb Collaboration
The CPU timing performance of several particle selection algorithms are shown in the context of the LHCb Upgrade trigger system. The algorithms are used to compare array-of-structure data models with structure-of-array models, and to compare scalar CPU instruction sets with the vector SSE and AVX2 instruction sets. [...]
