Unlike traditional methods that require extensive labeled data for each new class, zero-shot learning allows models to generalize and recognize new concepts they haven't been directly trained on. This is achieved by leveraging auxiliary information like semantic attributes and descriptions."},{"question":"How did Zero-shot Learning originate?","answer":"The concept of Zero-shot Learning dates back to the early 2000s. In 2009, researchers Dolores Parra and Antonio Torralba coined the term in their paper \"Zero-Shot Learning from Semantic Descriptions.\" This marked the beginning of exploring ways to enable models to adapt and learn from novel classes without explicit training."},{"question":"How does Zero-shot Learning work?","answer":"Zero-shot learning involves several steps:\r\n\r\n \t- Semantic Embeddings<\/strong>: Data and classes are embedded in a semantic space.<\/li>\r\n \t
