Python + Theano + keras installation on Windows: In fact, the process is very simple, first of all, to say the installation conditions:1, Win7 (32 and 64 can be, download the installation package must choose the corresponding) 2, Anaconda (go to the official download, open a little later will come out to download the link.) It was chosen because it built Python, as well as the NumPy, scipy two necessary libraries, and some other libraries, which were

There are a number of ways to save Keras model files and load Keras files. The models in Keras mainly include two parts of model and weight. JSON files, yaml files, HDF5 files The main way to save the model section: one is through the JSON file JSON file [Python] View plain copy # Serialize model to JSON Model_json = Model.to_json () with open ("Model.json", "W"

Full Stack Engineer Development Manual (author: Shangpeng) Python Tutorial Full Solution Keras uses a depth network to achieve the encoding, that is, the n-dimensional characteristics of each sample, using K as a feature to achieve the function of coding compression. The feature selection function is also realized. For example, the handwriting contains 754 pixels, and it contains 754 features, if you want to represent them with two features. How do yo

Keras Framework Training Model preservation and re-loading Experimental data mnist The Initial training model and save Import NumPy as NP from keras.datasets import mnist from keras.utils import np_utils from keras.models import sequential F Rom keras.layers import dense from keras.optimizers import SGD # Load data (X_train,y_train), (x_test,y_test) = Mnist.load_data () # (60000,28,28) print (' X_shape: ', X_train.shape) # (60000) print (' Y_shape: ',

. I've told you before, not to repeat.Try another optimizer (optimizer) before you've talked about it.Keras's callback function earlystopping () has been said before, no more 3.7.5 regularization method Regularization method means that when the objective function or cost function is optimized, a regular term is added after the objective function or the cost function, usually with L1 regular and L2 regular. The code snippet illustrates: From Keras impo

conv2d is: (3,300,1,64), that is, at this time the size of the conv1d reshape to get, both equivalent. In other words, conv1d (kernel_size=3) is actually conv2d (kernel_size= (3,300)), of course, the input must be reshape (600,300,1), you can do conv2d convolution on multiple lines. This can also explain why the use of conv1d in Keras can be done in natural language processing, because in natural language processing, we assume that a sequence is 600

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 the input format of lstm: (Samples,time_step,dim) is three-dimensional, so, first understand how to convert DNN input into lstm input,

Objective function Objectives The objective function, or loss function, is one of the two parameters that must be compiled for a model: Model.compile (loss= ' mean_squared_error ', optimizer= ' SGD ')You can specify a target function by passing a predefined target function name, or you can pass a Theano/tensroflow symbolic function as the target function, which should return only a scalar value for each data point, with the following two parameters as parameters: Y_true: Real data labels, theano

still very large. So in general, for the less complex verification code should choose a smaller network, only to encounter more complex verification code such as Chinese idioms, our experience is a complex network under the effect is better.In short, captcha recognition can be learned as a practiced hand project for deep learning, and it is easier to understand many of the concepts in deep learning theory in this practical project.Reproduced in: http://www.saluzi.com/t/topic/16027How to use dee

Use the following methods: From keras.utils import Plot_model Plot_model (Encoder_model, to_file= ' encomodel.png ', show_shapes=true) The author encountered such a problem in the course of using runtimeerror:failed to import Pydot.

Recently tried to learn tensorflow, but because the problem of learning resources leads to a series of problems, in simple terms, to learn tensorflow, to directly view the guidance of the GitHub, rather than according to the blog, Baidu on the guidance, because the version of the change too fast, similar to the College of Geeks, Blog guidance and code has not run, according to the error step-by-step processing instead into a dead end, the more mistakes, the following gives me in the installation

Keras in the use of the GPU when the feature is that the default is full of video memory. That way, if you have multiple models that need to run with a GPU, the restrictions are huge and a waste to the GPU. So when using Keras, you need to consciously set how much capacity you need to use the video card when you run it. There are generally three situations in this setting:1. Specify the video card2. Limit G
