In Run 3, LHCb will collect physics events at higher rates thanks to newly installed detectors that can sustain higher instantaneous luminosity and a revolutionary software trigger that will enable LHCb to rapidly process signal data. The EU-funded LHCbDFEI project will design full event interpretation algorithms to enhance the trigger performance. A deep neural network will process the low-level information from the detector and infer the heavy-hadron decays that occurred in the event. This should allow the quick identification of different types of background events and will provide further information on parent particles.
