AI & Machine Learning

"Machines that see, understand and reason"

Machine learning has become the common language of computer science. The labs in this area dig into the principles of learning algorithms themselves while studying how three very different signals - language, speech and vision - can be turned into intelligence.

    Intelligent agents that improve themselves through learning

    The Machine Learning Laboratory is interested in building intelligent learning agents that act better as experience accumulates. Working from the foundations of learning in statistics, information theory and linguistics, the laboratory develops new algorithms for deep learning and reinforcement learning. In data mining it designs and implements algorithms and software for acquiring and deriving knowledge, and validates them across applications such as pattern recognition, bioinformatics, recommender systems, and web and social networks.

    Financial economics seen anew through deep learning

    The Financial Machine Learning Laboratory sits where machine learning meets quantitative finance. It applies to financial market data the machine learning techniques that analyse material and infer new information, and studies how to construct portfolios and derivatives that satisfy a range of conditions. Its weight lies in fundamental research: understanding why some assets return more than others, interpreting why and how the various capabilities of deep learning work, and improving their performance.

    Technology that lets machines hear, understand and answer

    The Auditory Intelligence Laboratory studies systems that let people and computers converse without constraint through speech, the most convenient means of human communication. Continuous speech recognition and spoken dialogue understanding are its central subjects, and it develops audio multimedia retrieval that extracts fingerprints and melody information from an audio signal to identify the music it belongs to. The laboratory also works on computer-aided language learning systems built on large-vocabulary speech recognition and speech interface technology.

    Understanding images and reconstructing them in three dimensions

    The Computer Vision and Image Processing Laboratory works where computer vision, pattern recognition and machine learning meet. How image data should be acquired, analysed and processed, and how a three-dimensional world can be read out of two-dimensional images, are its central questions. Deep learning is used to solve established image analysis problems in new ways, with applications spanning face and fingerprint recognition, object recognition and tracking, panoramic image generation and three-dimensional shape reconstruction.

    Multimodal AI that keeps learning, stays grounded and acts on its own

    The Multimodal AI Laboratory (MAIL) studies large multimodal foundation models spanning vision-language and video-language, and has recently widened its scope to agent models that plan and act on their own. Its aim is to keep large models maintainable and deployable with confidence without retraining them from scratch each time. Three directions are pursued together: forgetting and continual learning, faithful and efficient inference, and agent and embodied AI.

    Generation, autonomous driving and vision inspection

    The Smart Vision & Media Lab focuses on making computer vision work in real industrial settings. It develops video generation with generative models, multi-camera autonomous driving built on object detection, human generation and analysis from three-dimensional point clouds, action recognition including hand gestures, and visual inspection for manufacturing.

    Making AI safer, more honest and more trustworthy

    The Human-Centered AI and Language Laboratory studies artificial intelligence, deep learning, language models, and AI safety and trustworthiness. It does not separate the question of what a language model can do better from the question of what it must not do, treating both as one research problem. As generative AI spreads rapidly through society, a model's harmfulness, bias, honesty and alignment are at once academic questions and urgent engineering demands.

    Machines that model human conversation

    An intelligent spoken dialogue system models the conversation between two people and replaces the modelled person with a machine. Building one requires dialogue modelling, dialogue understanding, dialogue generation, speech synthesis and speech recognition to come together as a whole. This laboratory concentrates on dialogue modelling based on reinforcement learning, and on dialogue understanding and speech synthesis using deep neural networks.

    Reasoning and alignment for Korean foundation models

    The Natural Language Processing and Conversational AI Laboratory studies the training and inference of the foundation models that underpin generative AI, and develops optimised training for multimodal agents and technology for commercial use in vertical domains. In reasoning it teaches AI to acquire chains of reasoning for solving problems, so that it produces trustworthy responses and actions, and studies large AI training and inference that supports decisions at an expert level.
