PhD, researcher, hacker. Putting Conjunctive Normal Form (CNF) Expansion to the Test. I recently participated in the Patent Olympics event. Remotely from my home. It was quite a learning experience.

PhD, researcher, hacker. Superstition is a form of overfitting in human learning. It’s likely to happen when the human has no clue or no good clue of what’s going on. Here, all kinds of noisy clues can become important for the human to predict what’s going to happen. Similarly, a machine learning model is likely to get superstitious when no good clues are provided. This is probably the most severe form of overfitting, and the model can even perform worse than a random baseline or a constant guess. It tak...

https://lezhao.wordpress.com/2011/11/08/the-age-of-reviews
PhD, researcher, hacker. The age of reviews. It is an age of many kinds of reviews.
