Reminder - please join us for the Apache MADlib Community Call on Thursday, May 10, at 1100 PDT / 1800 GMT. We'll discuss and demonstrate some of the new features in release 1.14
Webinar link: https://pivotal.zoom.us/j/994236734 New features: * Balanced datasets - sampling algorithm to balance classification datasets by resampling using various techniques including undersampling, oversampling, uniform sampling or user-defined proportion sampling * Personalized PageRank - new variant of PageRank graph algorithm which is better for personalization * Mini-batch optimizer for multilayer perceptron neural networks (and associated pre-processor function) - faster convergence, more accurate * PostgreSQL 10.2 support Improvements: * K-nearest neighbors - Added weighted averaging/voting by distance. * Summary - Added more statistics including number of positive, negative, zero values and 95% confidence intervals. * Multilayer perceptron - Added support for one-hot encoded categorical dependent variable for classification. * Lotsa bug fixes Release notes: https://github.com/apache/madlib/blob/master/RELEASE_NOTES Available now on PivNet. Thanks to the advanced analytics team for another great release!
