theano

I am using Keras (with Theano) to train my CNN model. Does anyone has idea how can I use it in my C++ application? Does anyone tried something similar? I have idea to write some python code that will generate a c++ code with network functions - any suggestion on it? I found a similar question here how to use Tensorflow Keras model in C++ but without answer. To answer my own question and have a solution - I wrote a plain c++ solution called keras2cpp (its code available on github). In this solution you store network architecture (in json) and weights (in hdf5). Then you can dump a network to a

I am interested in building reinforcement learning models with the simplicity of the Keras API. Unfortunately, I am unable to extract the gradient of the output (not error) with respect to the weights. I found the following code that performs a similar function ( Saliency maps of neural networks (using Keras) ) get_output = theano.function([model.layers[0].input],model.layers[-1].output,allow_input_downcast=True) fx = theano.function([model.layers[0].input] ,T.jacobian(model.layers[-1].output.flatten(),model.layers[0].input), allow_input_downcast=True) grad = fx([trainingData]) Any ideas on

I have a multi output(200) binary classification model which I wrote in keras. In this model I want to add additional metrics such as ROC and AUC but to my knowledge keras dosen't have in-built ROC and AUC metric functions. I tried to import ROC, AUC functions from scikit-learn from sklearn.metrics import roc_curve, auc from keras.models import Sequential from keras.layers import Dense . . . model.add(Dense(200, activation='relu')) model.add(Dense(300, activation='relu')) model.add(Dense(400, activation='relu')) model.add(Dense(300, activation='relu')) model.add(Dense(200,init='normal',

I've installed Anaconda . Now I want to install the Theano library in Anaconda. I have tried: The Theano installer for Anaconda from http://deeplearning.net/software/theano/install.html#windows-installer-for-anacondace , but it raises error "The installer could not find a version of Anaconda installed. Please download and install Anaconda CE". I have added ~/anaconda3, ~/anaconda3/scripts to the environment variable path. I have tried to install it by building the package as mentioned on Stack Overflow, How do I keep track of pip-installed packages in an Anaconda (Conda) environment? , but
