Information and Uncertainty
Information is reduction of uncertainty. This is the blog page for the information and uncertainty discussion group that meets at BIDS bi-weekly Friday 11:00am. The blog posts contain summaries of the meetings.
The discussion group is a forum where anybody can join and ask their data science questions about information, uncertainty, entropy, probabilities, machine learning, generalization and the rest of the universe. The discussion group facilitates and open, unjudgemental discussion (no grades, no promotion, no funding!) about the intuition and practical use of the concepts that are often deeply buried in mathematical language. We strive for clarity and understanding via concrete problems, practical examples and visualization.

- The Pigeon Hole Principle: Why do prime numbers exist?
These topics are just fillers. You are very much free to bring your own question and inspire the group with your question. We will also have guests on selected topics and will advertise on this website.
Note: Spontaneous ideas in an open academic discussion setting might be wrong. This is not a polished seminar class. This meeting assumes that the attendees are trained or are being trained on how to follow the scientific process to verify ideas to make them publishable scientific results.
