1.In this paper, by using patents as the middle products, a two-stage model is used to describe the total procedure of innovative activities of Chinese regional innovation system.本文应用两阶段模型,以专利作为中间产品,将区域创新活动分为技术产出阶段和经济产出阶段以及二者的综合阶段,并运用DEA方法中的...
然而,在这些开放的车辆数据集中也混合了许多模糊、灰色和低空间分辨率的图像,并且这些车辆是那些现有检测模型难以检测到的例子,例如Faster-RCNN、YOLO V3和FCOS。不足的生成方案和较差的方案分类性能导致这些硬例子的检测性能较差。此外,由于遥感场景的高度多样性,如多个场景、质量和规模,在实际的车辆场景中包含了更多的...
PASCAL VOC数据集由来自20个类的自然图像组成。这些网络是在VOC2007训练和VOC2012训练的联合集合上进行训练的,在VOC2007测试中重新获得了single-model的结果,结果如下表所示: 下表是在COCO数据集的结果: 检测结果可视化 COCO Test-dev上轻量级主干的评估。SNet 146虽然分类精度较低,但检测结果较好。 RoI warping前的...
The first section of this article delves into the particulars of the two-stage model of e-government growth. The second section outlines the existing literature in public administration on e-government development at the subnational level. The third section presents the database and methods used. ...
In this paper we extend the Moolgavkar-Venzon-Knudson two-stage model into nonhomogeneous cases. The probability generating functions (PGF) of initiated cells and tumors are derived under very general conditions. Using these PGF's we then obtain expected incidence functions of tumor and provide an...
Fast-RCNN的网络基于不同的base-model(vgg, resnet)等, 有不同结构. 我们现以最初的VGG网络作为base-model进行介绍. 首先, Fast-RCNN的输入包括两部分: 原始图片 通过RPN, SS等方法得到的RoI区域, 这个区域是一个矩形区域. 原始图像先通过vgg网络进行特征提取, 然后通过RoI pooling层. RoI pooling层的作用是...
We are going to useAutodistillto build a two-stage detection model. Autodistill is an ecosystem that lets you use foundation models likeCLIPand Grounding DINO to label data for use in training a fine-tuned model. Autodistill has connections for Grounding DINO and GPT-4V, the two models we...
A model of the affective-motivational dimension of pain is proposed that is based on phenomenological and psychophysical observations indicating that it is comprised of two stages. The immediate unpleasantness is based on several contributing processes, the most salient of which is the painful sensation...
Human selection has reshaped crop genomes. Here we report an apple genome variation map generated through genome sequencing of 117 diverse accessions. A comprehensive model of apple speciation and domestication along the Silk Road is proposed based on ev
it is a concept that has not received due attention from management scholars. In order to better our understanding of cronyism in work organizations, we present a two-stage model, grounded in the Chinese/Asian cultural context, of the antecedents to cronyism, and present a number of propositio...
