Python with MATLAB
AI for wireless directly call Python® library functionality from MATLAB®
Collaborate with colleagues who work in other deep learning frameworks to train and test PyTorch®, TensorFlow™, or ONNX™ models by calling Python directly from MATLAB. You can also import and export functions.
Workflow steps include data generation, data preparation, deep neural model training, model compression, model testing, and model deployment.
These examples focus on the training, testing, and deployment workflow steps to demonstrate running PyTorch models for channel state information (CSI) feedback compression and CSI prediction techniques using artificial intelligence (AI) in 5G wireless communication systems.
