Given myrecent interest in machine learning, this challenge peaked my interest. AlthoughPythonis the machine learninglingua franca, it is possible totrain a convolutional neural network (CNN) inRand perform (binary) image classification. Here, I will use anRinterface toKerasthat...
整体上采用迁移学习来训练神经网络,使用InceptionV3结构,框架采用keras. 具体思路: 读取图片数据,保存成.npy格式,方便后续加载 标签采用one-hot形式,由于标签隐藏在文件夹命名中,所以需要自行添加标签,并保存到.npy文件中,方便后续加载 将数据分为训练集、验证集、测试集 使用keras建立InceptionV3基本模型,不包括顶层,使...

We demonstrate Whetstone on a number of architectures and tasks such as image classification, autoencoders and semantic segmentation. Whetstone is currently implemented within the Keras wrapper for TensorFlow and is widely extendable.#Neuromorphic processors promise to be a low-powered platform for deep...
