I am going through the following blog on LSTM neural network:http://machinelearningmastery.com/understanding-stateful-lstm-recurrent-neural-networks-python-keras/ The author reshapes the input vector X as [samples, time steps, features] for different
#RNN 循环神经网络 import tensorflow as tf from tensorflow.examples.tutorials.mnist import input_data tf.set_random_seed(1) # set random seed # 导入数据 mnist = input_data.read_data_sets('MNIST_data', one_hot=True) # hyperparameters lr = 0.001 # learning rate t

今天终于弄明白,TensorFlow和Keras中LSTM神经网络的输入输出层到底应该怎么设置和连接了.写个备忘. https://machinelearningmastery.com/how-to-develop-lstm-models-for-time-series-forecasting/ Stacked LSTM Multiple hidden LSTM layers can be stacked one on top of another in what is referred to
最近这段时间系统性的学习了 BP 算法后写下了这篇学习笔记,因为能力有限,若有明显错误,还请指正. 什么是梯度下降和链式求导法则 假设我们有一个函数 J(w),如下图所示. 梯度下降示意图 现在,我们要求当 w 等于什么的时候,J(w) 能够取到最小值.从图中我们知道最小值在初始位置的左边,也就意味着如果想要使 J(w) 最小,w的值需要减小.而初始位置的切线的斜率a > 0(也即该位置对应的导数大于0),w = w – a 就能够让 w 的值减小,循环求导更新w直到 J(w) 取得最小值.如果
