Title: Risking your Tail: Curiosity, Danger & Exploration
Abstract: Risk and reward are critical balancing determinants of adaptive behaviour, associated respectively with neophobia and neophilia in the case of exploration. There are rather great differences in how individuals engage with novelty – with substantial consequences for what they are able to learn. Here, we consider how a modern formal treatment of risk (called the conditional value at risk) and pessimistic prior expectations can model some of these differences. Although the effects of risk on isolated decisions are well understood, additional issues arise in the context of sequences of choices, something that is inevitable in the case of exploration. This is joint work with Chris Gagne. Kevin Shen, Xin Sui and Kevin Lloyd.
