PyTorch in Practice: An Applications-First Approach (LFD473)

Start prototyping AI applications with PyTorch—leverage powerful pretrained models in Computer Vision and Natural Language Processing to tackle a wide range of practical, real-world challenges using one of the most popular deep learning frameworks.

Who Is It For
This course is designed for machine learning practitioners who want to add deep learning models in PyTorch - especially pretraining models for Computer Vision and Natural Language Processing - to quickly protype and deploy applications.

What You’ll Learn
The course begins with an overview of PyTorch, including model classes, datasets, data loaders and the training loop. Next the role and power of transfer learning is addressed along with how to use it with pretrained models. Practical lab exercises cover multiple topics including: image classification, object detection, sentiment analysis, text classification, and text generation/completion. Learners also will use their data to fine-tune existing models and leverage third-party APIs.

Reviews
Mar 2025
I liked the NLP segment. The use of BERT transformers, and the exposure to a mix of sentence transformers was very interesting, and kept me engaged during the training.
Mar 2025
The trainer's skill and content quality. I was hoping for a very practical, get your hands dirty training to actually build and use models. The content on using, tuning, and modifying existing models was great.
Dec 2023
The instructor was friendly and well prepared.
