Deep Learning thesis notes (8) Latest deep learning Overview Zouxy09@qq.com Http://blog.csdn.net/zouxy09 I have read some papers at ordinary times, but I always feel that I will slowly forget it after reading it. I did not seem to have read it again one day. So I want to sum up some useful knowledge points in my thesi

theoretical knowledge : UFLDL data preprocessing and http://www.cnblogs.com/tornadomeet/archive/2013/04/20/3033149.htmlData preprocessing is a very important step in deep learning! If the acquisition of raw data is the most important step in deep learning, then the preprocessing of the raw data is an important part of

In the words of Russian MYC although is engaged in computer vision, but in school never contact neural network, let alone deep learning. When he was looking for a job, Deep learning was just beginning to get into people's eyes. But now if you are lucky enough to be interviewed by Myc, he will ask you this question

This section mainly introduces a deep learning MATLAB version of the Toolbox, Deeplearntoolbox The code in the Toolbox is simple and feels more suitable for learning algorithms. There are common network structures, including deep networks (NN), sparse self-coding networks (SAE), CAE, depth belief networks (DBN) (based

models on a variety of platforms, from mobile phones to individual cpu/gpu to hundreds of GPU cards distributed systems. From the current documentation, TensorFlow supports the CNN, RNN, and lstm algorithms, which are the most popular deep neural network models currently in Image,speech and NLP. This time Google open source depth learning system TensorFlow can be applied in many places, such as speech reco

Transferred from: http://blog.csdn.net/zouxy09/article/details/8775518 Well, to this step, finally can talk to deep learning. Above we talk about why there are deep learning (let the machine automatically learn good features, and eliminate the manual selection process. As well as a hierarchical visual processing system

9. Common models or methods of deep learning 9.1 autoencoder automatic Encoder One of the simplest ways of deep learning is to use the features of artificial neural networks. Artificial Neural Networks (ANN) itself are hierarchical systems. If a neural network is given, let's assume that the output is the same as the i

,callbacks=[checkpointer, History]) train () Personal experience: Feel Keras use is very convenient, at the same time the source code is very easy to read, we have to modify the algorithm, you can read the bottom of the source code, learning will not be like the bottom of the caffe so troublesome, personal feeling caffe the only advantage is that there are a lot of open model, the source code, , Keras is not the same, with Python,

Written before: busy, always in a walk stop, squeeze time, leave a chance to think. Intermittent, the study of deep learning also has a period of time, from the beginning of the small white to now is a primer, halfway to read a little article literature, there are many problems. The trip to Takayama has only just begun, and this series is designed to record the path and individual

natural to think that we can use convolution to solve this problem.(iv) The model of deep learning to buildQuestion: Since we want to use a deep learning model, then how do we let the model identify our initial data.We can do this:1, each sentence is convolution into a vector, using this vector to find the distanceLik

Python vector: Import NumPy as np a = Np.array ([[[1,2],[3,4],[5,6]]) SUM0 = Np.sum (A, axis=0) sum1 = Np.sum (A, Axis=1) PR int SUM0 Print sum1 > Results: [9 12][3 7] Dropout In the training process of the deep Learning Network, for the Neural network unit, it is temporarily discarded from the network according to certain probability.Dropout is a big kill for CNN to prevent the effect of fitting. Output

One of the best tutorials to learn lstm is deep learning tutorial See http://deeplearning.net/tutorial/lstm.html The sentiment analysis here is actually a bit like Topic classification First learn to enter data format, run the whole process again, the data is also very simple, from the idbm download of the film review data, 50,000 annotated data, plus and minus half, 5,000 no annotated data, each film no mo

Entry route1, first of all on their own computer to install an open source framework, like TensorFlow, Caffe such, play this framework, the framework to use2, and then run some basic network, from the3, if there are conditions, the entire GPU computer, GPU run a lot faster, compared to the CPU To be more specific, I think you can follow these steps to learn it:First phase:1, realize and train only one layer of Softmax regression model for handwritten digital image classification;2, the implemen
