Modeling With Mixtures Of Linear Regressions

Modeling With Mixtures Of Linear Regressions. In this model, each observation is generated from one of the several unknown linear regression components, where the identity of the generated component is also unknown. Previously, estimation of the mixture of linear regression model has been.

Previous works either assume strong assumptions on the data distribution or have high complexity. We consider the problem of learning a mixture of linear regressions (mlrs). This mixture of linear regressions formulation has appeared in the computer science literature under the name “hierarchical.

The proposed model treats circular responses as the result of the modulo operation on unobserved linear responses. This mixture of linear regressions formulation has appeared in the computer science literature under the name “hierarchical mixtures of experts” model.this model has been considered from both frequentist and bayesian viewpoints.

They Are Useful In Many Disciplines.

Compared to hierarchical or partitioning clustering methods, mixture models sometimes produce more useful, and sometimes less useful solutions. The proposed model treats circular responses as the result of the modulo operation on unobserved linear responses.
