Maschinelles Lernen – Mathematica 11: Improved Machine Learning

Improved Machine Learning

Machine learning in Mathematica 11

Mathematica Version 11 extends and improves its machine learning capabilities. New functions allow users to extract features, reduce dimension, cluster data, optimize hyperparameters, and obtain interpretable models. The feature extraction functionality can be used to visualize datasets or to create semantic distances for search systems. Computer vision is substantially improved: ImageIdentify can recognize more than 10,000 objects, and performances of Classify on images are enhanced. Additionally, machine learning functions accept a wider range of data types.
