Is zero-shot learning easy to understand?
Zero-shot learning presents a steep initial learning curve compared to traditional supervised learning, requiring foundational knowledge in machine learning and AI. Its core concepts are not inherently intuitive.
Understanding hinges on grasping its fundamental principle: leveraging relationships or descriptions of seen classes to infer about completely unseen classes. Familiarity with semantic embeddings (like word vectors or attribute vectors), transfer learning concepts, and metadata organization is crucial. The approach's applicability depends heavily on the quality and availability of this auxiliary information describing classes and relationships. Its performance limitations compared to methods using target-class examples must also be acknowledged.
Despite the complexity, zero-shot learning is valuable for critical applications where obtaining labeled data for every possible class is impossible or impractical, such as identifying novel objects in images or rare events. Mastering it enables building AI systems capable of handling previously unknown categories, extending model flexibility.
