Temporal representation of state transitions
Artificial Intelligence for Engineering Design, Analysis and Manufacturing, 1999This paper describes a knowledge-based temporal representation of state transitions for industrial real-time systems. To allow expression of uncertainty, we shall define fluents as disjuncts of positive/negative time-varying properties. A state of the world is represented as a collection of fluents, which is usually incomplete in the sense that ...

Representation of Temporal Unawareness
2002In this paper we are concerned with the problem of designing of a conceptual framework for the construction of a flexible query answering mechanism that is adequate for selecting useful answers to queries, considering a multi-source and conflicting community of information sources.

Making Sense of Spatio-Temporal Preserving Representations for EEG-Based Human Intention Recognition
IEEE Transactions on Cybernetics, 2020Brain–computer interface (BCI) is a system empowering humans to communicate with or control the outside world with exclusively brain intentions. Electroencephalography (EEG)-based BCI is one of the promising solutions due to its convenient and portable ...

Representation of temporal information
International Journal of Computer & Information Sciences, 1982The use of the temporal logic formalism for representing information is reviewed. Two languages are introduced corresponding to two different ways of viewing information: as an assertion about properties of objects (syntactic view), or as a set of objects (semantic view). We define the semantics of the languages in terms of a model that generalizes the

Contrast and Order Representations for Video Self-supervised Learning
IEEE International Conference on Computer Vision, 2021This paper studies the problem of learning self-supervised representations on videos. In contrast to image modality that only requires appearance information on objects or scenes, video needs to further explore the relations between multiple frames/clips

Discounted-Value Representations of Temporal Preferences
Mathematics of Operations Research, 1985This paper examines the proposition that temporal preferences may be represented in terms of discount functions. An analytical framework is developed within which preferences are defined over a set of programs or prospects over time. Necessary and sufficient conditions for generalized discounting, discounting as well as exponential discounting are ...

Temporally Unfolding Neural Representation of Pictorial Occlusion
Psychological Science, 2006The human visual system possesses a remarkable ability to reconstruct the shape of an object that is partly occluded by an interposed surface. Behavioral results suggest that, under some circumstances, this perceptual process (termed amodal completion) progresses from an initial representation of local image features to a completed representation of a

Enhancing Video-Language Representations With Structural Spatio-Temporal Alignment
IEEE Transactions on Pattern Analysis and Machine IntelligenceWhile pre-training large-scale video-language models (VLMs) has shown remarkable potential for various downstream video-language tasks, existing VLMs can still suffer from certain commonly seen limitations, e.g., coarse-grained cross-modal aligning ...

Time drawings: Spatial representation of temporal concepts
Consciousness and Cognition, 2018Time representation is a fundamental property of human cognition. Ample evidence shows that time (and numbers) are represented in space. However, how the conceptual mapping varies across individuals, scales, and temporal structures remains largely unknown.
