Learning from Ambiguity
There are many learning problems for which the examples given by the teacher are ambiguously labeled. In this thesis, we will examine one framework of learning from ambiguous examples known as Multiple-Instance learning. Each example is a bag, consisting of any number of instances. A bag is labeled negative if all instances in it are negative. A bag is labeled positive if at least one instance ...
متن کاملAmbiguity in Social Learning
Are there differences in learning when information is ambiguous relative to when it is not? This paper explores how the introduction of ambiguity in a social learning game affects the strategies chosen by players. We test the multiple priors model in a laboratory experiment of informational cascades. Our findings suggest a high level of probabilistic sophistication in part of our subjects and p...
متن کاملLearning Under Ambiguity
This paper considers learning when the distinction between risk and ambiguity (Knightian uncertainty) matters. Working within the framework of recursive multiple-priors utility, the paper formulates a counterpart of the Bayesian model of learning about an uncertain parameter from conditionally i.i.d. signals. Ambiguous signals capture differences in information quality that cannot be captured b...
متن کاملA logic for reasoning about ambiguity
Standard models of multi-agent modal logic do not capture the fact that information is often ambiguous, and may be interpreted in different ways by different agents. We propose a framework that can model this, and consider different semantics that capture different assumptions about the agents’ beliefs regarding whether or not there is ambiguity. We examine the expressive power of logics of amb...
