60 Second Adventures in Artificial Intelligence

...data and make serendipitous discoveries. Transcript Artificial Vision One very common use of AI in science is for complex image analysis. Most AIs that perform image analysis are called “Convolutional Neural Networks” (CNN). A CNN is a special type of neural network that is based on simple models of how human vision works. A CNN learns an ensemble of simple pattern...

...analysis of data and interpretation of results; this is typical of M249. It is relatively self-contained and should be reasonably easy to understand for someone with a good knowledge of introductory statistics. However, a few techniques and definitions are present in the extract without explanation. Mathematical/statistical content at the Open University is usually...

Bayesian statistics

...data are observed, or information becomes available. Section 3 introduces the main ideas of the Bayesian inference process. The prior distribution summarises beliefs about the value of a parameter before data are observed. The likelihood function summarises information about a parameter contained in observed data and the posterior distribution represents what is known...
