What is it to do good ethics?

Much of my work in bioethics over the years has been throwing off ethics as pursued in the analytical tradition. I believe the field should steer clear of the rigid style of hyper-rationalist ethics and a reduction of ethics to a search for rules and principles. It should be open to a full range of influence, in style and substance, of literature, history and the social sciences. It should take...

Caring agents make good teachers and friendly companions

The new field of affective computing makes it possible to develop intelligent agents (graphical characters and robots) that are able to understand and respond to human emotions. As computers became more powerful during the 1990s, artificial intelligence (AI) researchers began to combine their technology with interactive graphics. They were able to produce intelligent characters that could inter...

Do people ask good questions?

People ask questions in order to efficiently learn about the world. But do people ask good questions? In this work, we designed an intuitive, gamebased task that allowed people to ask natural language questions to resolve their uncertainty. Question quality was measured through Bayesian idealobserver models that considered large spaces of possible game states. During free-form question generati...

Good traceability codes do exist

Traceability codes are combinatorial objects introduced by Chor, Fiat and Naor in 1994 to be used to trace the origin of digital content in traitor tracing schemes. Let F be an alphabet set of size q and n be a positive integer. A t-traceability code is a code C ⊆ Fn which can be used to catch at least one colluder from a collusion of at most t traitors. It has been shown that t-traceability co...
