当然只是用了paper search得到的结构,没有复现seach的过程。结果基本与paper中resnet50,640×640输入的结果一致,retinanet是37.4,nasfpn是40.1,不同之处在于focal loss的gamma设的是2,paper中是1.5。实验中发现gamma=2会比1.5稍好一点,所以结果

1/9/2018 · To use it with our FPN, we need to assign RoIs of different scales to the pyramid levels. Fast R-CNN[11]是一个基于区域的目标检测器,利用感兴趣区域(RoI)池化来提取特征。Fast R-CNN通常在单尺度特征映射上执行。要将其与我们的FPN一起使用,我们需要

FPN 特征金字塔或图像金字塔模型在深度学习之前的图像识别中已被广泛使用(号称Hand-crafted feature时代的万金油),如人脸识别中使用特征金字塔模型+AdaBoost提取不同尺度特征经行分类等。而在深度学习时代考虑

Jokes aside, the FPN paper is truly great, I really enjoyed reading it. It’s not easy to establish a baseline model which everyone can build on in various tasks, sub-topics and application areas. A small gist before we go into detail – FPNs are an add-on to general

与 RPN 一样,FPN 每层 feature map 加入 3×3 的卷积及两个相邻的 1×1 卷积分别做分类和回归的预测。在 RPN 中,实验对比了 FPN 不同层 feature map 卷积参数共享与否,发现共享仍然能达到很好性能,说明特征金字塔使得不同层学到了相同层次的语义特征。

The Problem Based Learning (PBL) meetings are the core activity of the FPN study programme and are the driving force for learning. Students work in small groups actively seeking practical solutions to scientific and real-world problems.

In order to solve the problem of complexity and uncertainty of fault propagation and analysis in protector, a new method for ESP protector fault diagnosis based on Fuzzy Petri nets (FPN) is proposed. Firstly, according to expert experiences and maintain rules, the FPN structure which has 28 places and 11 transitions is built to describe the protector fault propagation relations.
