Hugging Face Hands-On 12 x 5 Minutes Quick Course Lecture Schedule

Hugging Face Terminology

There are some terms you'll need to know to get the most out of working with Hugging Face.

Pretrained model: A model that has been trained on a large dataset for a specific task before being made available for use.

Inference: Inference is the process of using a trained model to make predictions or draw conclusions about new, unseen data based on the learned patterns from the training data.

Transformers: Transformers are models that can handle text-based tasks, such as translation, summarization, and text generation. They use a special architecture that relies on attention mechanisms to capture the relationships between words and sentences.

Tokenizer: A tokenizer is a process that breaks down text into smaller units called tokens. Tokens are usually words or subwords that can be used for natural language processing (NLP) tasks.
