Now that we have understood the internal working of LSTM model, let us implement it. To understand the implementation of LSTM, we will start with a simple example − a straight line. Let us see, if LSTM can learn the relationship of a straight line and predict it....

Motivate and briefly discuss an LSTM model as it allows one to predict more than one step ahead. Predict and visualize future stock market with current data If you're unfamiliar with deep learning or neural networks, you should look at our Deep Learning in Python course. It covers the basi...
本文具体讲解从caffemodel提取各个层的权重。权重是一般是很大的一个矩阵,比如[64,3,7,7], 需要把这些权重保存起来供Python读取。 一开始我也在c++想有啥办法和Python numpy一样的方便处理矩阵,想过了用json,xml或者直接用caffe自带的blob类,但是不会用啊!用caffe的proto应该是可以的,但是不会用。
当我们在默认状态stateless下,Keras会在训练每个sequence小序列(=sample)开始时,将LSTM网络中的记忆状态参数reset初始化(指的是c,h而并非权重w),即调用model.reset_states()。 为啥stateless LSTM每次训练都要初始化记忆参数? 因为Keras在训练时会默认地shuffle samples,所以导致sequence之间的依赖性消失,sample和sample...
