OBJECTIVES This study explores the analytic implications of using questions about difficulty with daily activities that do not specify whether to consider assistance. METHODS For 1,054 Asset and Health Dynamics of the Oldest Old Study Wave 2 respondents, we compared responses to questions about difficulty without reference to assistance (ambiguous difficulty) to those about difficulty without...

Facial expression recognition (FER) is a challenging classification task. Due to the subjectivity and ambiguity of performers spectators, compound facial hard be represented by one-hot label. In this paper, simple but efficient method, named real emotion seeker (RES), proposed recalibrate annotation sample latent distribution besides particular, subjective implicit knowledge transformed into po...

Under the umbrella of the innovative, ESA StarTiger program, a rapid prototyping study called Seeker was initiated which brought together a diverse range of partners from space/non-space to develop a prototype Mars rover system capable of autonomously exploring 6km of highly representative Mars terrain over a 3 day period. This paper reports on our approach and the final, successful field trial...

Interactive navigation through a video is a simple way for a user to get a quick overview of its content and to find interesting scenes. Although common video players provide only poor navigation facilities – in comparison to real video search applications – they are often employed by users due to their simplicity. We present a tool using a similarly simple interaction method but enabling much ...

This paper examines games with non-neutral option labels (such as “A”, “B”, “A”) and finds surprisingly invariant behaviour across games. The closely resembles the choices people make when they have to bet on one of options in individual lotteries. An option’s ‘representativeness’ (lack distinguishing features) ‘reachability’ (physical centrality, salience, valence) determine choice both lotter...
