  "Description": "We utilize the Bradley-Terry Model to estimate the\nabilities of teams using paired comparison data. For dynamic\napproximation of current rankings, we employ the Exponential\nDecayed Log-likelihood function, and we also apply the Lasso\npenalty for variance reduction and grouping. The main algorithm\napplies the Augmented Lagrangian Method described by Masarotto\nand Varin (2012) <doi:10.1214/12-AOAS581>.",
