Abstract: A dynamic user interface is configured to generate two types of information that may be generated by sophisticated computer systems such as expert systems and/or artificial intelligence. These types and include a “what if” prediction that illustrates probable outcomes from alternative actions, and a “similarity” analysis which shows a user how adjustments to input data may affect the resulting predictions. The “what if” prediction provides users guidance as to what actions may be most beneficial. The “similarity” analysis helps the users understand consequences of medical decisions.

Abstract: An automatic video tagging system which learns from videos, their web context and comments shared on social networks is described. Massive multimedia collections are analyzed by Internet crawling and a knowledge base is maintained that updates in real time with no need of human supervision. As a result, each video is indexed with a rich set of labels and linked with other related contents. Practical applications of video recognition require a label scheme that is appealing to the end-user (i.e. obtained from social curation) and a training dataset that can be updated in real-time to be able to recognize new actions, scenes and people. To create this dataset that evolves in real-time and uses labels that are relevant to the users, a weakly-supervised deep learning approach is utilized combining both a machine-learning pre-processing stage together with a set of keywords obtained from the internet.
