What Is Few-Shot Learning?
Few-shot learning is an AI technique where a model can perform a new task after seeing only a few examples (typically 1-10), either through specialized training or by providing examples directly in the prompt (in-context learning).
How Few-Shot Learning Works
Traditional machine learning requires thousands or millions of examples to learn a task. Few-shot learning enables models to generalize from just a handful of demonstrations. In large language models, this often takes the form of in-context learning: you provide a few input-output examples in the prompt, and the model extrapolates the pattern to handle new inputs. For example, showing an LLM three examples of product descriptions being converted to tweets, then asking it to do the same for a new product. Few-shot learning is one of the emergent capabilities of large models and is a practical technique in prompt engineering.
Real-World Examples
Providing ChatGPT with 3 examples of a specific email format and asking it to generate new emails following that exact style
A model classifying customer support tickets into categories after seeing just 5 labeled examples per category
An image classifier identifying a rare bird species after being shown only 3 photos of it
