Did you know?
WebIf a float is passed, the range is interpreted as (0, y_factor). Values represent a percentage of the image to shear over. For example, 0.3 shears pixels up to 30% of the way across the image. All provided values should be positive. If None is passed, no shear occurs on the Y axis. Defaults to None. Web概述. 在本文中，我们将提供一些面向小数据集（几百张到几千张图片）构造高效、实用的图像分类器的方法。. 本文将探讨如下几种方法：. 从图片中直接训练一个小网络（作为基准方法）. 利用预训练网络的bottleneck（瓶颈）特征. fine-tune预训练网络的高层. 本文 ...
