Description
What is our curiosity? How can we measure and model surprise of discovery? Philosophical questions, which have been pondered from different angles, also found definitions in Bayesian framework. I'll touch basics, review ideas, and illustrate on Twitter data how entropic measures can be efficiently used to detect events and summarise them.
Abstract
What is our curiosity? How can we measure and model surprise of discovery? Philosophical questions, which have been pondered from different angles, also found definitions in Bayesian framework. I'll review our understanding of surprise, touch theoretical basics, and finally illustrate on Twitter data how we can detect events and cherry pick most representative data points relying on entropic measures.
