Multilayer Perceptron (MLP) for multi-class softmax classification: from keras.models import Sequential from keras.layers import Dense, Dropout, Activation from keras.optimizers import SGD # 生成随机数据 import numpy as np x_train = np.random.random((1000,…

开始 Keras 序列模型(Sequential model) 序列模型是一个线性的层次堆栈. 你可以通过传递一系列 layer 实例给构造器来创建一个序列模型. The Sequential model is a linear stack of layers. You can create a Sequential model by passing a list of layer instances to the constructor: from keras.models import Se…

问题:一个数据又多个标签,一个样本数据多个类别中的某几类:比如一个病人的数据有多个疾病,一个文本有多种题材,所以标签就是: [1,0,0,0,1,0,1] 这种高维稀疏类型,如何计算分类准确率? 分类问题: 二分类 多分类 多标签 Keras metrics (性能度量) 介绍的比较好的一个博客: https://machinelearningmastery.com/custom-metrics-deep-learning-keras-python/ 还有一个介绍loss的博客: https:/…
