Computer vision for dummies. Machine Learning Books: A review. Raquo; About me. My name is Vincent Spruyt. I’m a machine learning and pattern recognition aficionado, data scientist, currently working as VP Chief Scientist at Sentiance. Working mostly on semi-supervised, self-adaptive and context-sensitive learning, big data and small data in high dimensional settings.

Computer vision for dummies. Machine Learning Books: A review. Raquo; Math basics. Raquo; Linear algebra. Raquo; A geometric interpretation of the covariance matrix. A geometric interpretation of the covariance matrix. Eigendecomposition of a covariance matrix. Covariance matrix as a linear transformation. In a previous article, we discussed the concept of variance. We showed that an unbiased estimator of the sample variance can be obtained by:. However, variance can only be used to explain the spread of...
