Recently in the study of using Keras to implement a lstm to train their own data (lstm the basic principles of self-tuition), the first of their own data with the DNN to train, and then to the LSTM, because the input is not the same, so some burn, DNN input format is input: (Samples,dim), is a two-dimensional data, and
right: Actually, the right is a left-hand image on the time series of the expansion, the last moment output is the input of this moment. It is important to note that, in fact, all neurons on the right are the same neuron, the left, which share the same weights, but accept different inputs at each moment, and then output to the next moment as input. This is the information stored in the past.Understanding the meaning of "loops" is the purpose of this chapter, and the formulas and details are des
(filters=256, kernel_size=5, padding=‘same‘, activation=‘relu‘, input_shape=(time_window_size, 1))) model.add(GlobalMaxPool1D()) model.add(Dense(units=time_window_size, activation=‘linear‘)) model.compile(optimizer=‘adam‘, loss=‘mean_squared_error‘, metrics=[metric]) print(model.summary()) return modelSet the output to your own. The exception points are the points with a larger predicted error deviation of the 90%.

Foreword : Actually before already used lstm, is in the depth study frame Keras to use directly, but to the present to LSTM detailed network structure still does not understand, the heart is worried about is uncomfortable. Today, read the TensorFlow
from the last signal. Implement the LSTM model in Python
There are a number of packages in Python that can be called directly to build lstm models, such as Pybrain, Kears, TensorFlow, cikit-neuralnetwork, etc. (more stamp here ). Here we choose keras. PS: If the operating system with Linux or Mac, strong push TensorFlow ... )

Two key issues:
1. Why has the memory function.
This is the problem solved in the RNN, because there is a recursive effect, the state of the hidden layer at the moment to participate in the calculation of this moment, the explicit point of the statement is the selection and decision-making reference to the last state.
2. Why lstm remember the long time.
Because the specially designed structure has the charac

People never judge a academic paper by those user experience standards this they apply to software. If The purpose of a paper were really promoting understanding, then most of them suck. A while ago, I read this article talking about academic pretentiousness and it speaks me heart out. My feeling are, papers are not for better understanding but rather for self-promotion. It ' s a way for scholars to declare achievements an

Keras provides many common, prepared layer objects, such as the common convolution layer, the pool layer, and so on, which we can call directly through the following code:
# Call a conv2d layer
from Keras import layers
conv2d = Keras.layers.convolutional.Conv2D (filters,\ kernel_size
