Zero-Shot Learning - Page 5

Zero-shot learning enables an AI model to handle a task or category without receiving a labeled example of that exact case during task-specific training. The model relies on broader representations, descriptions, instructions, or relationships learned earlier. A language model may classify text from a written label definition, while a vision system can connect unseen classes to semantic attributes. This flexibility is useful when categories change quickly or examples are scarce. Performance usually trails well-trained supervised systems and depends on whether the new task is represented in the model’s prior knowledge. Clear instructions, meaningful labels, confidence thresholds, and evaluation on truly unseen cases help distinguish genuine generalization from accidental familiarity with training data.
