Day 6 Model Selection and Multimodel Inference

Day 6 Model Selection and Multimodel Inference . Topics. Model selection: how do you choose between (and compare) alternate models? Multimodel inference: how do you combine information from more than 1 model?. Topics. Model comparison. Evidence ratios. Likelihood ratio tests.

EM and model selection

EM and model selection. Missing variable problems. In many vision problems, if some variables were known the maximum likelihood inference problem would be easy fitting; if we knew which line each token came from, it would be easy to determine line parameters
