Supplementary Material – Ambiguity Helps : Classification with Disagreements in Crowdsourced Annotations

Abstract

In this section we give all the necessary details to implement the EP algorithm [1] for the GPCconf method described in the main manuscript. We show how to compute the EP posterior approximation from the product of all approximate factors and how to implement the EP updates to refine each approximate factor. We also show how to compute the EP approximation… (More)
