I have a data matrix in "one-hot encoding" (all ones and zeros) with 260,000 rows and 35 columns. I am using Keras to train a simple neural network to predict a continuous variable. The code to mak...

I am working on Deep Nets using keras. There is an activation "hard sigmoid". Whats its mathematical definition ? I know what is Sigmoid. Someone asked similar question on Quora: https://www.quora...

I am importing pymc3 and theano. Using jupyter notebook, python version 3.11.5.I have installed theano 1.0.5 and pymc3 3.11.4. However when I import theano and pymc3 as below: import numpy as np im...

What would cause a Convolutional Neural Network to diverge? Specifics: I am using Tensorflow's iris_training model with some of my own data and keep getting ERROR:tensorflow:Model diverged with lo...

I try to install Theano by Anaconda. It works, but when I enter the python -i, import theano shows No module named 'theano'. Do I need to switch another interpreter of Python, how? Also, for the pa...

I have a few thousand audio files and I want to classify them using Keras and Theano. So far, I generated a 28x28 spectrograms (bigger is probably better, but I am just trying to get the algorithm ...

I'm using Keras with the Theano backend on Ubuntu 16.04. My setup has been working without issues, however, all of a sudden I get the following error when I import Keras (import keras): ValueErr...

I am working on a reinforcement learning task and decided to use keras NN model for Q value approximation. The approach is common: after each action the reward is stored in a memory replay array, t...

I can not for the life of me figure out how to switch the image ordering. images are read in (x,x,3) format, theano requires it to be in (3,x,x) format. I tried changing the order with numpy.array(...

I'm trying to study the neural-network-and-deep-learning (http://neuralnetworksanddeeplearning.com/chap1.html). Using the updated version for Python 3 by MichalDanielDobrzanski (https://github.com/...

running a Dense feed-forward neural net in Keras. there are class_weights for two outputs, and sample_weights for a third output. fore some reason it prints the progress verbose display for each ba...

I am currently seeing the API of theano, theano.tensor.nnet.conv2d(input, filters, input_shape=None, filter_shape=None, border_mode='valid', subsample=(1, 1), filter_flip=True, image_shape=None, *...

I don't understand why there is the need to flip filters when using convolutional neural networks. According to the lasagne documentation, flip_filters : bool (default: True) Whether t...

I'm trying to reshape a tensor from [A, B, C, D] into [A, B, C * D] and feed it into a dynamic_rnn. Assume that I don't know the B, C, and D in advance (they're a result of a convolutional network)...

I installed theano but when I try to use it I got this error: WARNING (theano.configdefaults): g++ not detected! Theano will be unable to execute optimized C-implementations (for both CPU and ...

I get different results (test accuracy) every time I run the imdb_lstm.py example from Keras framework (https://github.com/fchollet/keras/blob/master/examples/imdb_lstm.py) The code contains np.ran...

I am currently trying to reproduce the results of the following article. http://karpathy.github.io/2015/05/21/rnn-effectiveness/ I am using Keras with the theano backend. In the article he talks ab...

I have a layer output I want to multiply by a scalar. I can do this with a lambda layer ie sc_mult = Lambda(lambda x: x * 2)(layer) which works fine. But if I want to use a different scalar for ...

I have python 3. I installed "Theano" bleeding edge and "Keras" using pip install --upgrade --no-deps git+git://github.com/Theano/Theano.git and also pip install --upgrade git+git://github.com/...

Please, I do need a light here. I want to install numpy using a good BLAS/LAPACK lib on Windows, but absolutely no page explains the process well enough. It seems OpenBLAS is a good and fast option...
