oneAPI Data Analytics Library (oneDAL) is a powerful machine learning library that helps you accelerate big data analysis at all stages: preprocessing, transformation, analysis, modeling, validation, and decision making.
The library implements classical machine learning algorithms. The boost in their performance is achieved by leveraging the capabilities of Intel® hardware.
The oneDAL is part of the UXL Foundation and is an implementation of the oneAPI specification for oneDAL component.
There are different ways for you to build high-performance data science applications that use the advantages of oneDAL:
- Use oneDAL C++ interfaces with or without SYCL support (learn more)
- Use Intel(R) Extension for Scikit-learn* to accelerate existing scikit-learn code without changing it
- Use daal4py, a standalone package with Python API for oneDAL Deprecation Notice: The Java interfaces are removed from the oneDAL library.
Check System Requirements before installing oneDAL.
You can download the specific version of oneDAL or install it from sources.
