LLMs for Sentiment Analysis Training in Madrid, Spain

This hands-on course focuses on using Large Language Models (LLMs) to perform sentiment analysis on text data. Participants will learn how LLMs like BERT, RoBERTa, and GPT can be fine-tuned or prompted for sentiment tasks. The course includes working with Hugging Face Transformers, preparing datasets, evaluating models, and deploying sentiment analysis systems in real-world applications.
