The book’s forward was written by Julia co-creator and Julia Computing co-founder Stefan Karpinski.

New Threading Capabilities in Julia v1.3: Jameson Nash (Julia Computing), Jeff Bezanson (co-creator of Julia and co-founder of Julia Computing) and Kiran Pamnany (Caltech) wrote an article published by Intel titled New Threading Capabilities in Julia v1.3. The article explains how Julia v1.3 facilitates multithreading quickly and easily.

Deep Learning Using Neural Networks in Julia: Alex Luedtke, Marco Carone, Noah Simon and Oleg Sofrygin published Learning to Learn from Data: Using Deep Adversarial Learning to Construct Optimal Statistical Procedures in Science Advances. “For a two-dimensional generalized linear model, we found that it took approximately 40 times as long to evaluate our procedure on a dataset as to run a generalized linear model in Julia... We also compared the runtime of our learned clustering procedure to the EM and k-means implementations that we used, both of which were based on Julia code from publicly available repositories—links to these repositories can be found in our source code. On 10,000 randomly generated datasets, our learned procedure, on average, evaluated approximately 10 times faster than k-means and 400 times faster than EM. This improved runtime came at the cost of an initial offline training time of 6 hours on a GPU cloud computing service... We learned and interrogated our procedures in Julia. The neural networks for the point estimation and prediction experiments were fitted using Knet, and the neural networks for the confidence region construction experiments were fitted using Flux.”

New Papers from Timothy Holy Featuring Julia: Timothy Holy, Professor of Neuroscience at Washington University in St. Louis, has co-authored two new papers featuring Julia: Sensory Coding Mechanisms Revealed by Optical Tagging of Physiologically Defined Neuronal Types by Donghoon Lee, Maiko Kume, Timothy Holy and Fast Objective Coupled Planar Illumination Microscopy by Cody Greer and Timothy Holy.

About Julia and Julia Computing

Julia is the fastest high performance open source computing language for data, analytics, algorithmic trading, machine learning, artificial intelligence, and other scientific and numeric computing applications. Julia solves the two language problem by combining the ease of use of Python and R with the speed of C++. Julia provides parallel computing capabilities out of the box and unlimited scalability with minimal effort. Julia has been downloaded more than 13 million times and is used at more than 1,500 universities. Julia co-creators are the winners of the 2019 James H. Wilkinson Prize for Numerical Software and the 2019 Sidney Fernbach Award. Julia has run at petascale on 650,000 cores with 1.3 million threads to analyze over 56 terabytes of data using Cori, one of the ten largest and most powerful supercomputers in the world.

Julia Computing was founded in 2015 by all the creators of Julia to develop products and provide professional services to businesses and researchers using Julia.
