This four-part webinar series showcases significant areas of new and expanded functionality in Mathematica and the Wolfram Language. Session one features developer presentations on new machine learning superfunctions and the latest enhancements to the neural net framework. Session two looks at the extended capabilities of the entity framework, including a deeper look at food and nutrition data, cultural and historical entities and computable knowledge in biology and medicine. Session three explores the latest calculus and algebraic computation and scientific visualization functionality. And finally, session four introduces Wolfram Language functionality for integrating with Python and NodeJS, interfacing with the Unity game engine, deploying to microcontrollers, interacting with blockchains and compiling/optimizing code.
