Binary pairwise models
WebBinary pairwise models play a key role in computer vision, both directly and as critical subroutines in solving more complex problems (Boykov et al., 2001). Note that it is possible to convert any positive discrete MRF into an equivalent binary pairwise model (Eaton and Ghahramani, 2013),1though this may lead to a much larger state space. http://proceedings.mlr.press/v38/weller15.pdf

WebDec 1, 2009 · An approximate procedure based on the pseudo-likelihood of Besag (1975) is implemented and this procedure is faster than the competing exact method proposed by Lee, Ganapathi, and Koller (2006a) and only slightly less accurate. We consider the problems of estimating the parameters as well as the structure of binary-valued Markov … WebAbstract: Training semantic similarity model to detect duplicate text pairs is a challenging task as almost all of datasets are imbalanced, by data nature positive samples are fewer than negative samples, this issue can easily lead to model bias.
