小样本学习在单目标视觉识别上已经取得了优异成绩,但在多目标尤其是由混叠目标的多图像上尚未取得进展(2019年).由此作者提出将Faster-RCNN/Mask CNN的ROI结合Predictor-head Remodeling Network (PRN)实现元学习的目标检测. PRN 是一个全卷积网络,与 Faster RCNN/ Mask RCNN backbone 共享参数,输入为带有 bbox ...
But interestingly,we found that the blended undiscovered objects could be “pre-processed” via theRoI featuresproduced by the first stage inference in Faster /Mask R-CNNs.Each RoI feature refers to a single object or background, so Faster /Mask RCNN may disentangle the complex information that...

Cube R-CNN 可以检测图像中的每个项目及其所有 3D 属性,包括旋转、深度和域。由于 OMNI3D 的复杂性,我们的模型表现出很好的泛化性,并且比使用单个集成模型的室内和城市环境的其他研究表现更好。从如此广泛的数据中学习存在困难,因为 OMNI3D 包含焦距剧烈波动的图片,这加剧了尺度深度的模糊性。他们通过虚拟深度在数据...
Based on the meta-learning principle, we propose a new meta-learning framework for object detection named "Meta-RCNN", which learns the ability to perform few-shot detection via meta-learning. Specifically, Meta-RCNN learns an object detector in an episodic learning paradigm on the (meta) ...

新人入职Meta后机器学习项目的初体验充满了挑战与实践。以下是关键点的总结:项目启动与预期:兴奋与预想:新人鼠鼠对首次接掌的机器学习项目充满期待,预想中会运用如faster RCNN、ResNet、Mask RCNN等先进算法。数据获取与处理:数据源头问题:实际操作中,首要问题是找不到图片数据源头,通过与产品经理...
FAIR,一家国际顶尖的科研机构,最近迎来了一场人才变动的风暴。R-CNN的作者Ross Girshick选择离开,加入艾伦人工智能研究所(AI2)。此前,ResNeXt一作谢赛宁和Georgia Gkioxari也相继离职,分别加入纽约大学和加州理工学院任教。这一系列变动引发了人们对FAIR流失CV领域大神的讨论。Ross Girshick在个人主页上...
假设上文提到的CNN的损失函数如下: minW,B,zL(y,f(x;h(z;W,B)))+γD(W)+γD(B)+λR(z)minW,B,zL(y,f(x;h(z;W,B)))+γD(W)+γD(B)+λR(z) 这里L(⋅,⋅),D(⋅), and R(⋅)L(⋅,⋅),D(⋅), and R(⋅) 分别是视觉任务的损失函数,权值衰减项损失函数,和...
