base model:关键帧生成模型 TSR:temporal super-resolution,也就是插帧 SSR:spatial super-resolution:超分 主要包含两个模块,视频生成(STUnet)+超分 STUnet:将输入在时间和空间上都做downsample,而不是像之前的unet只在空间上做downsample。在T2I的原始结构上加入了时序的block,包括convolution和attention,同时也加入...
A space-time correlation model for multielement antenna systems in mobile fading channels For the analysis and design of multielement antenna systems in mobile fading channels, we need a model for the space-time cross correlation among the links... A Abdi,M Kaveh - 《IEEE Journal on Selected ...
We use a time-space network (TSN) to model the DCFRPC and formulate it as a mixed-integer linear programming (MILP) problem. In the TSN, we consider the flows of the AGVs and materials separately and then synchronize these flows considering the constraints in the formulation. This approach ...
In this research we develop a novel timespace network model with the objective of minimizing the length of time needed for emergency repair, subject to related operating constraints. The model is expected to help the decision maker to efficiently set an emergency repair schedule within a limited ...
Time–space hybrid modelRecommendationMarkov model has been used to model user navigational behavior on the World Wide Web. Most existing Markov models based on recommendation algorithms make recommendation just through Web server logs without Web topology. In this chapter, a time-space hybrid Markov ...
We develop a minimalist compartmental model to study the impact of mobility restrictions in Italy during the Covid-19 outbreak. We show that, while an early lockdown shifts the contagion in time, beyond a critical value of lockdown strength the epidemic
原文最终比较发现divided space-time attention的效果最好,在K400和SSv2上能够取得最好的效果。同时joint space-time也可以取得不错的效果,原文继续在模型的容纳力上进行了测试,结果如下: 上图表明随着图片的分辨率以及帧数的增加,divided space-time attention可以取得比较优雅的增加模型复杂度,因此后续的实验中原文就...
