Vizier is a research area that focuses on the development of intelligent systems to assist users in navigating complex information spaces and making decisions. It involves the use of techniques from artificial intelligence, information retrieval, machine learning, and human-computer interaction to design and implement systems that can effectively support users in tasks such as information exploration, recommendation, and decision-making. Vizier systems typically incorporate visualization techniques to help users make sense of large amounts of data and information. Overall, the goal of vizier research is to create intelligent systems that can act as virtual assistants to help users explore and understand complex information spaces more efficiently and effectively.
