In a previous tutorial, we built a CNN-based image classifier from scratch using the Keras API. In this tutorial, you will learn how to finetune the state-of-the-art vision transformer (ViT) on your custom image classification dataset using the Huggingface Transformers library in Python....
近几年来GAN图像生成应用越来越广泛,其中主要得益于GAN 在博弈下不断提高建模能力,最终实现以假乱真的图像生成。GAN 由两个神经网络组成,一个生成器和一个判别器组成,其中生成器试图产生欺骗判别器的真实样本,而判别器试图区分真实样本和生成样本。这种对抗博弈下使得生成器和判别器不断提高性能,在达到纳什平衡后生成...
我们建立一个新的遥感数据集以便后面使用 # create a products directory within the data dir which won't be uploaded to Githubimg_dir='../data/products/'# check to see if the dir it exists, if not, create itifnotos.path.exists(img_dir):os.makedirs(img_dir)# filepath for image we're...
