Talks given by Dr Hansen

Obviously this only lists talks that are listed through talks.cam. Furthermore, this facility only works if the speaker's e-mail was specified in a talk. Most talks have not done this.

• How do you know when you’re right? – On hallucinations, the limits of trustworthy AI, and the power of ‘I don't know’
• Can everything be computed? On the Solvability Complexity Index and towers of algorithm.
• The Solvability Complexity Index and Approximations of Spectra of Operators
• Compressed Sensing - Introduction and Future Aspects

Talks organised by Dr Hansen

This list is based on what was entered into the 'organiser' field in a talk. It may not mean that Dr Hansen actually organised the talk, they may have been responsible only for entering the talk into the talks.cam system.
