Locally linear coordination

WitrynaOur local linear models are represented by a mixture of factor analyzers, and the “global coordi- nation” of these models is achieved by adding a regularizing term to the standard maximum likelihood objective function. The regularizer breaks a degeneracy in the mixture model’s parameter space, favoring models whose internal coor- dinate ...
