Learn to fine-tune RoBERTa for multi-label classification of unhealthy comments using PyTorch Lightning in this comprehensive coding tutorial. Explore practical Python implementation techniques to create a language model capable of identifying attributes like sarcasm, hostility, and dismissiveness in online comments. Follow along with step-by-step guidance on setting up Google Colab, importing necessary libraries, inspecting data, creating PyTorch datasets and data modules, building the classifier model, and training and evaluating the results. Access the provided Colab notebook to practice hands-on and gain insights into Hugging Face and Transformer models, focusing on implementation rather than theory. Benefit from additional resources, including research papers on RoBERTa and the Unhealthy Comment Corpus, to deepen your understanding of the underlying concepts.
