WebMar 5, 2024 · The multi-label classification problem involves finding a multi-valued decision function that predicts an instance to a vector of binary classes. Two methods are widely used to build multi-label classifiers: the binary relevance method and the chain classifier. Both can induce a polynomial multi-valued decision function by using Bayesian network … WebNow run a single instance x through this chain. Suppose classifier AvsBC assigns x a posterior probability Pr (A) = 0.51. Under this result the ensemble would presumably stop, and never explore the other options, and thus might miss out on higher posterior probability assignments (e.g., under BvAC you might get Pr (B) = 0.60).
