Probabilistic Representation

Probabilistic representation learning focuses on encoding data as probability distributions rather than deterministic points, enabling richer uncertainty quantification and improved robustness to noise and ambiguity. Current research emphasizes using probabilistic models like Gaussian Mixture Models and multivariate Gaussian distributions within various architectures, including Bayesian networks, autoencoders, and contrastive learning frameworks, to achieve this. This approach enhances performance in diverse applications such as semantic segmentation, affordance learning, and cross-modal retrieval by explicitly modeling uncertainty and improving generalization, particularly in scenarios with limited data or noisy observations. The resulting improved model interpretability and reliability are significant advancements for AI systems.
