[b]Description[/b]

Welcome to the Introduction to LangChain course! Very recently, we saw a revolution with the advent of Large Language Models. It is rare that something changes the world of Machine Learning that much, and the hype around LLM is real! That's something that very few experts predicted, and it's essential to be prepared for the future.LangChain is an amazing tool that democratizes machine learning for everybody. With LangChain, every software engineer can use machine learning and build applications with it. Prior to LangChain and LLMs, you needed to be an expert in the field. Now, you can build an application with a couple of lines of code. Think about language models as a layer between humans and software. LangChain is a tool that allows the integration of LLMs within a larger software.Topics covered in that course:LangChain BasicsLoading and Summarizing DataPrompt Engineering FundamentalsVector Database BasicsRetrieval Augmented GenerationRAG Optimization and Multimodal RAGAugmenting LLMs with a Graph DatabaseAugmenting LLMs with toolsHow to Build a Smart Voice AssistantHow to Automate Writing NovelsHow to Automate Writing SoftwareThe course is very hands-on! We will work on many examples to build your intuition on the different concepts we will address in this course. By the end of the course, you will be able to build complex software applications powered by Large Language Models!
