TacticAI
Google DeepMind, in collaboration with Liverpool FC, releases TacticAI, a geometric deep-learning system that analyzes football corner kicks and suggests alternative tactics for coaches to explore.

GNN-based setup: Players are modeled as nodes in a graph whose features encode positions, velocities, and roles; the network predicts receiver identity, shot probability, and related outcomes jointly.
Tactic exploration: Coaches can sample alternative player setups for a given corner and rank them by predicted outcome, turning TacticAI into a what-if engine rather than a static predictor.
Expert preference: In blind A/B tests with Liverpool FC experts, TacticAI's suggestions were preferred over existing professional tactics 90% of the time.
Effective retrieval: A secondary retrieval system lets coaches find historically similar corner kicks to study, turning the large game-footage archive into a searchable tactical library.
