A GRAPH-BASED METHOD FOR SOCCER ACTION SPOTTING USING UNSUPERVISED PLAYER CLASSIFICATION. In this presentation we talk about our graph-based model for action spotting in soccer games. The goal of action spotting is to identify the specific time an action occurs. Our model represents players, referees, and goalkeepers as nodes in a graph and connects according […]

The Perfekt theory of M-ideals We revisit some ideas of K.-M.~Perfekt who has provided an elegant framework to detect the biduality between function or sequence spaces defined in terms of some o-resp.\ O-condition. We present new proofs under somewhat weaker assumptions than before and apply the result to Lipschitz spaces.
