Machine Learning Using oneAPI
Learn how to accelerate machine learning workloads using packages like scikit-learn*,
XGBoost, NumPy, SciPy, and pandas—all powered by oneAPI.
Realize performance gains with a few extra lines of code on the latest Intel® CPUs and GPUs.
Use stock versions or Intel® Extension for Scikit-learn*, which is part of AI Tools from Intel.
Overview
AI Tools give data scientists, AI developers, and researchers familiar Python* tools and frameworks to accelerate end-to-end data science and analytics pipelines on Intel architecture. The components are built using oneAPI libraries for low-level compute optimizations. AI Tools maximize performance from preprocessing through machine learning and provides interoperability for efficient model development.
This learning path enables you to:
- Achieve drop-in acceleration for data preprocessing and machine learning workflows with compute-intensive Python packages, scikit-learn*, and XGBoost, optimized for Intel.
- Gain direct access to analytics and AI optimizations from Intel to ensure that your software works together seamlessly.
Who is this for?
Data scientists, data engineers, and software developers who want to learn how to accelerate machine learning workloads.
What will I be able to do?
- Adapt common scikit-learn algorithms to offload computation to accelerator devices like CPUs and GPUs.
