Discovering the patterns to enable machines to recognise, understand and analyse human behaviour.
Recognition, Learning and Reasoning Lab

The Recognition, Learning and Reasoning (ReLER) Lab is committed to enable machines to accurately recognize the environment, adaptively understand the human interactions, and autonomously analyse behaviour through reasoning. To this end, we work on computer vision, learning algorithms, natural language, and their intersections. Concretely, we aim at developing novel methods for object, face, action, and event recognition by localising positions and segmenting the instances in images and videos.
Besides recognition, it is also essential for the machines to communicate fluently with humans by understanding natural language instructions and queries. To bridge the literacy gap, ReLER Lab develops captioning, question answering and dialogue systems for better visual understanding and reasoning.
