Struggling to make a neural network mimic a basic if statement
The curvature of the cost surface with these particular inputs and outputs makes this a bit of a pathological example. A 'good' solution can be found by just outputting 0.333 all the time, and if you …

Stochastic gradient descent for neural networks with tied weights
First of all, shouldn't your equation (1) be the following?
$$
\frac{\partial E}{\partial w_{tied}} = \frac{\partial E}{\partial f}(\frac{\partial f}{\partial h_1}\frac{\partial h_1}{\partial w_1}+\fr …

Image classification, narrow domain with custom labels
Here's one tutorial on training a deep convnet from scratch in Keras. There should be plenty of other examples on the web.
You could still use a pre-trained model for this, and just re-train some of …
