An AI chatbot is a program within a website or app that simulates human conversations using natural language processing (NLP). Chatbots are programmed to address users' needs independently of a human operator. Common chatbot functions include answering frequently asked questions and helping users navigate a website or app. In this course, explore the AI chatbot application flow and learn about data loading and text preprocessing. Next, discover how to transform the data into numeric values and perform one-hot data encoding. Finally, practice creating and training models, loading a trained model, defining a response function, and setting test questions. Upon completion, you'll be able to develop a simple chatbot using transformers that will automatically reply to user questions.
