Reasoning with uncertainty and time in AI has numerous applications and examples in various domains and fields, such as robotics, natural language processing, computer vision, biomedical informatics, and social media analysis. For example, robots must reason about their state, the environment, tasks, and human users while dealing with uncertainty and change in perception, action, communication, and learning. Natural language processing requires systems to reason about the meaning, context, sentiment, and intention of natural language texts and utterances while dealing with ambiguity, inconsistency, and variability in language use and understanding. Computer vision requires systems to reason about objects, scenes, actions, and events in images and videos while handling uncertainty and noise in recognition, detection, segmentation, and tracking. Biomedical informatics requires systems to reason about the diagnosis, prognosis, treatment, and prevention of diseases and disorders while accounting for uncertainty and variability in symptoms, tests, outcomes, and interventions. Lastly, social media analysis requires systems to reason about the opinions, emotions, preferences, and behaviors of social media users while coping with uncertainty and change in online interactions, feedbacks, and trends.
