Metric Larning 深度学习中最先应用metric learning思想之一的便是DeepID2了。其中DeepID2最主要的改进是同一个网络同时训练verification和classification（有两个监督信号）。其中在verification loss的特征层中引入了contrastive loss。Contrastive loss不仅考虑了相同类别的距离最小化，也同时考虑了不同类别的距离最大化，通...

在上次教程Python-OpenCV —— Machine Learning讲述了如何建立模型,进行训练,然后利用模型对新获得的照片进行预测并给出预测值,本期教程针对某个特定的物体进行检测,将其标记出来,分为3个步骤,第一:训练特定物体,第二: 训练模型 级联分类器 前几天看到一个笑话,很有意思,说的是 ...
The package works by building an augmentationpipelinewhere you define a series of operations to perform on a set of images. Operations, such as rotations or transforms, are added one by one to create an augmentation pipeline: when complete, the pipeline can be executed and an augmented dataset...
