High-Level Machine Learning

Mathematica 12: High-Level Machine Learning

Version 12 pushes further in the direction of having fully automated machine learning capabilities for every task and data type. Most existing functions have been improved, notably by the introduction of a new automation procedure. New functions are also introduced, mostly in the unsupervised learning domain in order to learn without labeled data, but also in the active learning domain in order to learn from a "teacher". Overall, this updated high-level framework should give the possibility for novices to easily implement machine learning solutions, and for experts to reduce their development time.

Neural Network Framework

Mathematica 12: Neural Network Framework

Version 12 completes its high-level neural network framework in terms of functionality, while improving its simplicity and performance. A variety of new layers and encoders have been added, in particular, to handle sequential data such as text or audio. Importantly, a model repository is introduced, bringing a collection of pre-trained networks to be used as is, symbolically manipulated, or fine-tuned to a specific task. Finally, performance has been improved for most hardware configurations, including the possibility to train using multiple graphic cards. This framework is arguably the easiest existing tool to build neural network applications, yet with broad capabilities and without performance compromise.

Machine Learning for Images

Mathematica 12: Machine Learning for Images

Version 12 image processing and computer vision use extensively updated machine learning and neural net capabilities and introduce several built-in, high-level functions for object recognition, face analysis, restyling and more. In addition, with a growing number of pre-trained networks available from the Wolfram Neural Net Repository, one can use available pre-trained networks immediately, or manipulate and reassemble them to train on new data. Powerful network surgery capabilities enable transfer learning, which allows for solving problems using much smaller datasets.
