Keywords

💡AI Chatbot

An AI Chatbot is an artificial intelligence software designed to simulate conversation with users in natural language. In the context of the video, the AI Chatbot is being built using Hugging Face's tools and libraries, showcasing how to create a functional chatbot that can engage in a conversation about cooking dinner, for example.

💡Hugging Face

Hugging Face is a company that provides tools and libraries for developers to build and deploy AI models, including chatbots. The video demonstrates the use of Hugging Face's 'Transformers' library to quickly and easily build a chatbot, highlighting its user-friendly nature and the efficiency it brings to the development process.

💡Transformers Library

The Transformers Library by Hugging Face is a collection of pre-trained models that can be fine-tuned for various tasks, including natural language processing. The video script mentions installing and upgrading this library as a foundational step in building the AI chatbot, emphasizing its importance in the process.

💡Pipeline

In the context of the video, a pipeline refers to a sequence of processing steps that the data goes through. The script mentions using the 'pipeline' from the Transformers library, which simplifies the use of models for tasks like chatbot conversations by abstracting complex code and offering a simple API.
