    摘要: "The Bradley-Terry model for obtaining individual skill from paired comparisons has been
    popular in many areas. In machine learning, this model is related to multi-class probability
    estimates by coupling all pairwise classification results. Error correcting output codes
    (ECOC) are a general framework to decompose a multi-class problem to several binary
    problems. To obtain probability estimates under this framework, this paper introduces a
    generalized Bradley-Terry model in which paired individual comparisons are extended to
    paired team comparisons. We propose a simple algorithm with convergence proofs to solve
    the model and obtain individual skill. Experiments on synthetic and real data demonstrate
    that the algorithm is useful for obtaining multi-class probability estimates. Moreover, we
    discuss four extensions of the proposed model: 1) weighted individual skill, 2) home-field
    advantage, 3) ties, and 4) comparisons with more than two teams"
