This guide provides an overview of applications that can be addressed using pre-trained Large Language Models (LLMs). It outlines the learning objectives, which include understanding various applications of LLMs, downloading and interacting with LLMs through Hugging Face datasets and models, and the significance of prompt engineering. The document discusses how to identify suitable models for specific natural language processing (NLP) tasks, such as summarization, sentiment analysis, and translation. It also details the Hugging Face Hub, which hosts models, datasets, and tools necessary for working with LLMs. Additionally, the guide emphasizes the importance of model selection, including filtering by task, size, and performance metrics. By the end of the module, users are expected to have a foundational understanding of how to leverage LLMs for various NLP tasks effectively.
