What is zero-shot learning in AI?
Zero-shot learning in AI refers to the ability of a model to correctly infer or make decisions about data classes it has not been trained on. The model is trained on a set of classes and then tested on a different set of classes. The goal is to enable the model to generalize from its training data to unseen classes based on high-level attributes or descriptions.
How does zero-shot learning work?
Zero-shot learning works by leveraging semantic information about the classes, such as attributes or descriptions, to bridge the gap between seen and unseen classes. For example, if a model is trained to recognize animals based on attributes like 'has feathers', 'has four legs', etc., it can potentially recognize an unseen animal like a 'penguin' based on its attributes, even if it has never seen a penguin during training.
Zero-shot learning is a challenging problem and an active area of research in AI.
What are the applications of zero-shot learning?
Zero-shot learning has potential applications in many areas of AI, including image and video classification, object recognition, natural language understanding, and recommendation systems. For example, in image classification, a model could be trained to recognize a set of objects and then be able to recognize new objects based on their attributes. In natural language understanding, a model could be trained to understand a set of concepts and then be able to understand new concepts based on their descriptions.
