Description
Ongoing activities include, but are not limited to:
Jet tagging [CMS-DP-2025-032]
Electron reconstruction [CMS-DP-2023-047, CMS-DP-2024-098]
Vertex reconstruction (usage in correlator) [CMS-DP-2021-035, CMS-DP-2022-020]
ML for Puppi
Event selection (especially VBF, di-Higgs)
Soft tau reconstruction in the Level-1 Data Scouting system
CERN group/ Experiment
EP-CMG, NGT
| Working area | Area 2: Optimal AI deployment for Online Data Processing |
|---|---|
| Project goals | Deliver ML models that increase the acceptance of the Phase 2 Level 1 Trigger, especially for CMS Phase 2 priorities centralized around the Correlator (mostly) and Global Trigger (somewhat) subsystems extension to the Level-1 Data Scouting (no fixed-latency requirements, inference also on conventional GPUs or other accelerators as in the HLT) Operate ML models in the Phase 2 Level 1 Trigger (calibration, monitoring, automated retraining) |
| Timeline | Funded by NGT (mainly Task 3.6) up to 2029, with contributions from some CMG staff |
| Available person power | Several staff, fellows, doctoral and technical students in CMG, and many other User contributors in CMS |
| Additional person power request | none |
| Is this an already ongoing activity? | Yes |
| Indicative hardware resources needs | Access to a GPU cluster with LCG-like software stack and cvmfs access with fast storage facilities across the full duration of the project. FPGAs for testing |
