接上回, 这次做了一个多元回归 这里贴一下代码 import numpy as np np.random.seed(1337) from sklearn.model_selection import train_test_split import matplotlib.pyplot as plt import keras from keras.models import Sequential from keras.layers import Activation from keras.layer
#基于IMDB数据集的简单文本分类任务 #一层embedding层+一层lstm层+一层全连接层 #基于Keras 2.1.1 Tensorflow 1.4.0 代码: '''Trains an LSTM model on the IMDB sentiment classification task. The dataset is actually too small for LSTM to be of any advantage compared to simpler, much faster

本节介绍循环神经网络及其优化 循环神经网络(RNN,recurrent neural network)处理序列的方式是,遍历所有序列元素,并保存一个状态(state),其中包含与已查看内容相关的信息.在处理两个不同的独立序列(比如两条不同的 IMDB 评论)之间,RNN 状态会被重置,因此,你仍可以将一个序列看作单个数据点,即网络的单个输入.真正改变的是,数据点不再是在单个步骤中进行处理,相反,网络内部会对序列元素进行遍历,RNN 的特征在于其时间步函数 Keras 中的循环层 from ker
