Applications of Zero-Shot Learning

As a member of a research group involved in computer vision, I wanted to write this short article to briefly present what we call "Zero-shot learning" (ZSL), an interesting variant of transfer learning, and the current research related to it. Today, many machine learning methods focus on classifying instances whose classes have already been seen in training. Concretely, many applications require classifying instances whose classes have not been seen before. Zero-shot learning is a promising learning method, in which the classes covered by training instances and the classes we aim to classify are disjoint. In other words, Zero-shot learning is about leveraging supervised learning with no additional training data.
