5 Guidelines for Building a Neural Network Architecture

1. KISS; yes, keep it simple.
2. Build, train, and test for robustness rather than preciseness.
3. Don’t over-train your network.
4. Keep track of your results with different network designs to see which characteristics work better for your problem domain.

Is neural network accurate?

We show experimentally that the accuracy of a trained neural network can be predicted surprisingly well by looking only at its weights, without evaluating it on input data. Furthermore, the predictors are able to rank networks trained on different, unobserved datasets and with different architectures.

How to choose the best neural network architecture?

According to the previous tutorial, the first step for deducing the best number of hidden layers and neurons is to visualize the samples in a 2D graph. Below is the Python code used for plotting the data. The data inputs are stored in the input_data variable, while the output_data variable stores their outputs.

Why are there so many hidden layers in neural networks?

The number of hidden layers is highly dependent on the problem and the architecture of your neural network. You’re essentially trying to Goldilocks your way into the perfect neural network architecture — not too big, not too small, just right.

What are the advantages and disadvantages of neural networks?

In our articles on the advantages and disadvantages of neural networks, we discussed the idea that neural networks that solve a problem embody in some manner the complexity of that problem. Therefore, as the problem’s complexity increases, the minimal complexity of the neural network that solves it also does.

How to reduce the size of a neural network?

An approach to counteract this is to start with a huge number of hidden layers + hidden neurons and then use dropout and early stopping to let the neural network size itself down for you.
