Introduction : Natural language processing (NLP) is a field of computer science that deals with the interaction between computers and human (natural) languages. NLP has a wide range of applications, including machine translation, text summarization, and question answering. In recent years, the field of NLP has been revolutionized by the emergence of large language models (LLMs). LLMs are a type of artificial intelligence (AI) that are trained on massive datasets of text and code. This allows them to learn the statistical relationships between words and concepts, which makes them very good at generating text that is both grammatically correct and semantically meaningful. LLMs have the potential to revolutionize the way we interact with computers. They can be used to create more natural and conversational interfaces, improve machine translation, and empower content creation and editing. Understanding Large Language Models: In this section, we will delve into the basics of LLMs and explai...
