BAH: Ambivalence / Hesitancy in Videos
The first multimodal, subject-based video dataset for recognizing ambivalence and hesitancy (A/H) for digital behavioural-change interventions.
LIVIA, the Laboratory of Imaging, Vision and Artificial Intelligence, builds cost-effective deep-learning models from weakly-annotated data, for healthcare, security, industry and beyond.
Our expertise spans deep and machine learning, computer vision, pattern recognition and the optimization of complex systems, with a focus on adaptive, weakly-supervised and multimodal learning for deployable models.
Adaptive, incremental, weakly-supervised and multimodal learning for deep models under limited annotations.
Visual perception of 2D and 3D scenes; static and dynamic modelling of environments.
Biometrics, classifier ensembles and dynamic selection for robust decision-making.
Models that adapt to users and shifting conditions in real-time, resource-limited settings.
Multimodal fusion of vision, audio, language and physiological signals.
Convex and combinatorial optimization, evolutionary and multi-objective methods.
From hospitals to smart buildings, LIVIA turns weakly-annotated data into reliable systems across six core domains.
Medical and satellite imaging.
Biometrics and surveillance.
Monitoring health and marketing.
Industrial vision and secure embedded AI.
Document security and explainable AI.
Natural language understanding.
Ranked among Canada's leading vision & learning groups, with strong funding, training and publication output.
We release large-scale, carefully annotated datasets, with code, pretrained weights and reproducible benchmarks.
