To say lstm, you have to start with RNN. RNN is a tool for modeling sequential data, which is used in the fields of speech recognition, machine translation and so on. Lstm can be said to be an improved version of RNN, in short, rnn the long-range sequence processing will appear gradient disappear or explode this phenomenon, make training not up (note: Gradient disappears or explosion problem not only in the
PrefaceThe sequence problem is also a interesting issue. Looking for a meeting LSTM of the material, found not a system of text, the early Sepp Hochreiter paper and disciple Felix Gers 's thesis did not look so relaxed. The first thing to start with was a review in 15, and it didn't look very smooth at the time, but looking at the first two (part) and then looking back at the formulation part of the article would be clearer.Originally intended to writ
LSTM (long-short term Memory, LSTM) is a time recurrent neural network that was first published in 1997. Due to its unique design structure, LSTM is suitable for handling and predicting important events with very long intervals and delays in time series. Based on the introduction of deep learning three Daniel, Lstm net

For a more intuitive understanding of the data format, some printing (print) is added to the code, and a comment is added, which is the output value

Long Short Term Memory networks–usually just called "Lstms" –are a special kind of RNN, capable of learning long-term D Ependencies. They were introduced by Hochreiter Schmidhuber (1997), and were refined and popularized through many people in following Work.1 They work tremendously a large variety of problems, and are now widely used.
Lstms are explicitly designed to avoid the long-term dependency. Remembering i

RNN (recurrent neuralnetworks, cyclic neural network)
For a common neural network, the previous information does not have an impact on the current understanding, for example, reading an article, we need to use the vocabulary learned before, and the ordinary neural network does not do this, so there is a circular neural network, its greatest advantage is the retention of information before.

The article includes a few parts:1. Why try to do this project.2. Why did you choose this model?3. Where does the data from the model come from.4. The optimization process of the model.5. The direction in which the project can be further improved.

steps are not correct, it can also get some "inspiration" from earlier information to form new predictions. (one might say that if you are training RNN, you can add noise and other methods to keep it stable when encountering strange inputs.) But we still feel that the introduction of better memory methods is more efficient and long-term development of the move. )LSTMLstm refers to long short-term Memory. This is a structure that was developed in the 1997.Probably.The design of this structure is

The difference with convolution neural networks is that convolution neural networks pay more attention to the global fuzzy perception (like we look at a picture, in fact, we do not see a pixel, but only the overall grasp of the picture content), and Rnns is to focus on the adjacent location of the reconstruction, this shows that for the language task, Rnns is more persuasive (language is always made up of

Sesame HTTP: TensorFlow lstm mnist classification, tensorflowlstm
This section describes how to use LSTM of RNN for MNIST classification. RNN may be slower than CNN but can save more memory space.Initialization
First, we can initialize some variables, such as the learning rate, number of node units, and RNN layers:
learning_rate = 1e-3num_units = 256num_layer = 3input_size = 28time_step = 28total_steps = 20
The convolutional lstm network was initiated to solve the precipitation nowcasting problem. Because the traditional full connection lstm does not consider the relationship between space. But this model can also be extended to arbitrary spatiotemporal sequence forecasting problem.The parameters in this model are all three-dimensional tensor. As long as the operation of vector multiplication can be replaced b
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 and make others admire. Therefore the golden standard for a academic paper h
issuesLong-time dependence is such a problem that it is difficult to learn the relevant information when the prediction point is far from the dependent information. For example, in the sentence "I was born in France, ..., I can speak French", to predict the end of "French", we need to use the context "France". In theory, recursive neural networks can deal with such problems, but in fact, conventional recurrent neural networks do not solve long-time dependencies well, and good LSTMS can solve th
