'Alois Christian Knoll' 'Shu Li'] Active mapping is an important technique for mobile robots to autonomously explore and recognize indoor environments. View planning, as the core of active mapping, determines the quality of the map and the efficiency of exploration. However, most current view-planning methods focus on…

Slow change blindness, when attentive observers fail to notice large changes that happen gradually, raises questions about how visual information is combined across time. One plausible integration strategy is serial dependence: blending information from the recent past into current perception. Here, we investigate…

Observers perceive objects in the world as stable over space and time, even though the visual experience of those objects is often discontinuous and distorted due to masking, occlusion, camouflage, noise, etc. How are we able to easily and quickly achieve stable perception in spite of this constantly changing visual…

Modeling Authors: ['Yuqi Chen' 'Kan Ren' 'Yansen Wang' 'Yuchen Fang' 'Weiwei Sun' 'Dongsheng Li'] Modeling continuous-time dynamics on irregular time series is critical to account for data evolution and correlations that occur continuously. Traditional methods including recurrent neural networks or Transformer models…

This paper develops a compact collecting semantics for the residual behaviour left by nonterminating computation. For sequential time this is the tail-cluster set of the stream in the Stone-Cech compactification of the observation space. It gives a common semantics to ordinary recurrence, mixed recurrent behaviour, and…

Everyday cognition requires observers to find organization in continuous behavior as surface form changes. Behavioral streams can carry a constraint that governs what remains coherent across variation. This study examines whether such a constraint can remain publicly legible when it structures an action stream and…

Events can be modeled through a geometric approach, representing event structures in terms of spaces and mappings between spaces. At least two spaces are needed to describe an event, an action space and a result space. In this article, we invoke general mathematical structures in order to develop this geometric…

Research has shown that infants are able to track a moving target efficiently – even if it is transiently occluded from sight. This basic ability allows prediction of when and where events happen in everyday life. Yet, it is unclear whether, and how, infants internally represent the time course of ongoing movements to…

—Unlike traditional cameras, event cameras measure changes in light intensity and report differences. This paper examines the conditions necessary for other traditional sensors to admit eventified versions that provide adequate information despite outputting only changes. The requirements depend upon the regularity of…

Online monitoring of embedded real-time systems can be achieved by reduction of an adequate property language, like Metric Interval Temporal Logic, to timed automata and symbolic execution of the resulting automata on the trace observed from the system. This direct construction however only is faithful if observation…

Behavioural research requires the use of sampling methods to document the occurrence of responses observed. Sampling/recording methods include ad libitum, continuous, pinpoint (instantaneous), and one-zero (interval) sampling. Researchers have questioned the utility of each sampling method under different contexts. Our…

Statistical and machine-learning models of longitudinal biological data evaluate change by comparing each new observation against the trajectory implied by prior observations, assuming the process generating that trajectory is stable. We use “data substrate” to mean the underlying structure of the longitudinal data…

The notion of action simulation refers to the ability to re-enact foreign actions (i.e., actions observed in other individuals). Simulating others' actions implies a mirroring of their activities, based on one's own sensorimotor competencies. Here, we discuss theoretical and experimental approaches to action simulation…

Serial dependence is influenced by sensory uncertainty and contextual continuity, but it remains controversial whether these influences reflect separate mechanisms or different expressions of a shared updating process. Across two time reproduction experiments (N = 44), we examined how motion coherence and coherence…

Judgments of the present visual world are affected by what came before. When judgements of visual properties such as orientation are biased in the direction of preceding stimuli, this is called visual serial dependence. Visual serial dependence is thought to arise from mechanisms that support perceptual continuity…

'James Evans' 'Jamie Anderson' 'David P French'] Background Unobtrusive observation is a promising method for assessing physical activity and other well-being behaviors (eg, social interactions) in urban environments, without participant burden and biases associated with self-report. However, current methods require…

Crystallization stands as a prime example of self-assembly. Elementary building blocks converge, seemingly adhering to an intricate blueprint, orchestrating order from chaos. While classical theories have long described crystallization as a monomer-by-monomer addition (whether involving atoms, ions, molecules or…

We introduce a method for calculating p-values when testing causal theories about a single case, for instance when conducting process tracing. As in Fisher's (1935) original design, our p-value indicates how frequently one would find the same or more favorable evidence while entertaining a rival theory (the null) for…

Assessing the susceptibility of stainless steel (SS) to pitting corrosion remains challenging due to the difficulty in identifying nanometre-scale imperfections in the passive surface films. Traditional analytical methods are costly, time-consuming, and limited to model systems with adequate signal-to-noise ratios. We…
