Résumé du cours
Learn how to apply and fine-tune a Transformer-based Deep Learning model to Natural Language Processing (NLP) tasks.
In this course, you'll:
- Construct a Transformer neural network in PyTorch
- Build a named-entity recognition (NER) application with BERT
- Deploy the NER application with ONNX and TensorRT to a Triton inference server
Upon completion, you’ll be proficient in task-agnostic applications of Transformer-based models.
