Vectorizing Random Number Generators for Greater Speed: PCG and xorshift128+ (AVX-512 edition)

Tools & Languages random number generatorsposted by Daniel Lemire November 8, 2018

Most people designing random number generators program using regular code. If they are aiming for speed, they probably write functions in C. However, our processors have fast “vectorized” (or SIMD) instructions that can allow you to go faster. These instructions do several operations at once. For example, recent Skylake-X... Read more

Build a Multi-Class Support Vector Machine in R

Modeling Rposted by Daniel Gutierrez November 2, 2018

Support Vector Machines (SVMs) are quite popular in the data science community. Data scientists often use SVMs for classification tasks, and they tend to perform well in a variety of problem domains. An SVM performs classification tasks by constructing hyperplanes in a multidimensional space that separates cases of different... Read more
