[Click on image for larger view.]Figure 1:CIFAR-10 Image Classification Using PyTorch Demo Run After training, the demo program computes the classification accuracy of the model on the test data as 45.90 percent = 459 out of 1,000 correct. The classification accuracy is better than random gue...
pytorch是一个基于Python的科学计算包,它主要有两个用途: 类似于Numpy但是能利用GPU加速 一个非常灵活和快速用于深度学习的研究平台 所以说PyTorch既可以看作加入了GPU支持的numpy,同时也可以看成一个拥有自动求导功能的强大的深度神经网络。PyTorch的优点到底是啥呢?PyTorch不仅仅是定义网络结构简单,而且还很直观灵活。...

利用pytorch实现Visualising Image Classification Models and Saliency Maps saliency map saliency map即特征图,可以告诉我们图像中的像素点对图像分类结果的影响。 计算它的时候首先要计算与图像像素对应的正确分类中的标准化分数的梯度(这是一个标量)。如果图像的形状是(3, H, W),这个梯度的形状也是(3, H, W);...
