Algebraic Change-Point Detection [PDF]
Applicable Algebra in Engineering, Communication and Computing, 2009 Elementary techniques from operational calculus, differential algebra, and noncommutative algebra lead to a new approach for change-point detection, which is an important field of investigation in various areas of applied sciences and engineering ...

Change Acceleration and Detection
The Annals of Statistics, 2020 A novel sequential change detection problem is proposed, in which the change should be not only detected but also accelerated. Specifically, it is assumed that the sequentially collected observations are responses to treatments selected in real time. The

A detection theory account of change detection [PDF]
Journal of Vision, 2004 Previous studies have suggested that visual short-term memory (VSTM) has a storage limit of approximately four items. However, the type of high-threshold (HT) model used to derive this estimate is based on a number of assumptions that have been ...

Optimal change point detection and localization in sparse dynamic networks [PDF]
, 2021 We study the problem of change point localization in dynamic networks models. We assume that we observe a sequence of independent adjacency matrices of the same size, each corresponding to a realization of an unknown inhomogeneous Bernoulli model.

Selecting change image for efficient change detection
IET Signal Processing, 2022 Change detection (CD) is a fundamental problem that aims at detecting changed objects from two observations. Previous CNN‐based CD methods detect changes through multi‐scale deep convolutional features extracted from two images.

Direction-dominated change vector analysis for forest change detection
International Journal of Applied Earth Observations and Geoinformation, 2021 As forest is under increasing pressure, the rapid conversion or degradation of forest has attracted strong concern. Obtaining quantitative information of forest change based on satellite imagery becomes necessary and urgent, especially the detailed “from-

Tactile Change Detection [PDF]
First Joint Eurohaptics Conference and Symposium on Haptic Interfaces for Virtual Environment and Teleoperator Systems, 2005 Interest in the use of tactile information displays has grown rapidly in recent years. However, relatively little research has been conducted to explore any cognitive and/or attentional limitations that may be inherent when using the body as a receptor surface for the transmission of information.

CAAI Transactions on Intelligence Technology, 2023 Recently, ground coverings change detection (CD) driven by bitemporal hyperspectral images (HSIs) has become a hot topic in the remote sensing community. There are two challenges in the HSI‐CD task: (1) attribute feature representation of pixel pairs and

Change detection: training and transfer. [PDF]
PLoS ONE, 2013 Observers often fail to notice even dramatic changes to their environment, a phenomenon known as change blindness. If training could enhance change detection performance in general, then it might help to remedy some real-world consequences of change ...
