π Conversational AI refers to technology that enables machines to understand and respond to human language in an interactive manner.
π The key components of conversational AI are Natural Language Understanding (NLU) and Dialogue Management.
π€ Rasa is an open-source framework for building conversational AI applications, providing tools for NLU, dialogue management, and deployment on various messaging platforms.
π€ The video demonstrates how to build a chatbot using Python and Rasa.
π‘ The video covers the process of setting up a Rasa project from scratch, including installation, project initialization, and folder structure.
π The key files discussed are nlu.yml for training examples, domain.yml for intent and response configuration, rules.yml for rule-based conversations, and stories.yml for training dialogue management.
π€ Building a chatbot involves training a dialogue management model to respond appropriately based on user inputs and context.
π The chatbot project structure consists of folders such as models, test, config, credentials, domain, and endpoints, each serving different purposes.
βοΈ Important files in the project include nlu.yml for training data, domain.yml for defining the chatbot's capabilities, and stories.yml for specifying conversation flow.
π€ The rules.yml file is used to define conversational rules and control the flow of the conversation based on specific conditions.
π Rules provide explicit control over conversation flow, allowing for fine-grained control over the dialog management of the chatbot.
π§ Rules can be useful for handling fallback scenarios, overriding default behavior, and simplifying complex dialog management.
π€ To build a chatbot with Python and Rasa, you need to define intents, entities, and responses in the domain.yml file.
βοΈ Training the chatbot model can be done by specifying intents, entities, and actions in the stories.yml file and then executing the 'Rasa train' command.
π Entity extraction in Rasa plays a crucial role in gathering important information from user requests and generating appropriate responses.
π Flask is a lightweight framework for building web applications and APIs, known for its simplicity and flexibility.
π‘ Flask provides features such as routing, templating, extensibility through extensions, and built-in development server.
π¬ The integration of Rasa chatbot with Flask allows for the creation of a practical project, combining web application functionality with chatbot capabilities.
π‘ The video demonstrates how to build a chatbot using Python and Rasa.
π§ Steps are shown for adding style and functionality to the chatbot user interface.
βοΈ The video covers integrating the chatbot with a Flask project and handling user input.
