return train_losses, test_losses, train_acc, test_acc I simply copy and paste it from other projects and I find it redundant to use that same code each time, it is useful almost in every model I test and usually looks quite similar. I wonder if there is a shortcut or some module w...

To install scikit-neuralnetwork (sknn) is as simple as installing any other Python package: pip install scikit-neuralnetwork Custom Neural Nets Let’s define X_train and y_train from the Iris dataset to run the examples below: from sklearn.datasets import load_irisdata = load_iris()X_train...
PyTorch is not a Python binding into a monolithic C++ framework. It is built to be deeply integrated into Python. You can use it naturally like you would use NumPy / SciPy / scikit-learn etc. You can write your new neural network layers in Python itself, using your favorite libraries and...
本文翻译自RECURRENT NEURAL NETWORKS TUTORIAL, PART 2 – IMPLEMENTING A RNN WITH PYTHON, NUMPY AND THEANO。 github地址 在这篇博文中,我们将会使用Python从头开始实现一个循环神经网络,并且利用Theano(一个在GPU上执行操作的库)优化原始的实现。所有的代码可以在github上获得。我将会跳过一些不影响理解循环神经网络...
Neural Tangents is designed to serve as a drop-in replacement forstax, extending the(init_fn, apply_fn)tuple to a triple(init_fn, apply_fn, kernel_fn), wherekernel_fnis the kernel function of the infinite network (GP) of the given architecture. Below is an example of computing the cov...
