SocioScape – Spatio-temporal Visual Analysis of Group Dynamics in Social Networks

SocioScape – a Tool for Interactive Exploration of Spatio-Temporal Group Dynamics in Social Networks

We introduce SocioScape, an interactive tool for the visual exploration of spatially referenced, dynamic social networks. The tool combines a novel depiction methodology that illustrates the evolution of social groups with a spatio-temporal visualization showing the movement of these groups in the environment. The depiction technique used by SocioScape provides an alternative to graphs, allowin...

STCS-GAF: Spatio-Temporal Compressive Sensing in Wireless Sensor Networks- A GAF-Based Approach

Routing and data aggregation are two important techniques for reducing communication cost of wireless sensor networks (WSNs). To minimize communication cost, routing methods can be merged with data aggregation techniques. Compressive sensing (CS) is one of the effective techniques for aggregating network data, which can reduce the cost of communication by reducing the amount of routed data to t...

معرفی شبکه های عصبی پیمانه ای عمیق با ساختار فضایی-زمانی دوگانه جهت بهبود بازشناسی گفتار پیوسته فارسی

In this article, growable deep modular neural networks for continuous speech recognition are introduced. These networks can be grown to implement the spatio-temporal information of the frame sequences at their input layer as well as their labels at the output layer at the same time. The trained neural network with such double spatio-temporal association structure can learn the phonetic sequence...

Recognition of Visual Events using Spatio-Temporal Information of the Video Signal

Recognition of visual events as a video analysis task has become popular in machine learning community. While the traditional approaches for detection of video events have been used for a long time, the recently evolved deep learning based methods have revolutionized this area. They have enabled event recognition systems to achieve detection rates which were not reachable by traditional approac...
