Left: neural network before dropout. Right: neural network after dropout. Why dropout works? It might seem to crazy to randomly remove nodes from a neural network to regularize it. Yet, it is a widely used method and it was proven to greatly improve the performance of neural networks. So, why does it work so well?

The general set of strategies against this curse of overfitting is called regularization and early stopping is one such technique. The idea is very simple. The model tries to chase the loss function crazily on the training data, by tuning the parameters.

Within this context, a single input image will be processed by the neural network as many times as epochs we run, enabling the network to memorize part of the image if we train for too long. The ...

By default, no regularizer is used in any layers. A weight regularizer can be added to each layer when the layer is defined in a Keras model. This is achieved by setting the kernel_regularizer argument on each layer. A separate regularizer can also be used for the bias via the bias_regularizer argument, although this is less often used.

Introduce and tune L2 regularization for both logistic and neural network models. Remember that L2 amounts to adding a penalty on the norm of the weights to the loss. In TensorFlow, you can compute the L2 loss for a tensor t using nn.l2_loss (t). The right amount of regularization should improve your validation / test accuracy.

Dropout regularization is a computationally cheap way to regularize a deep neural network. Dropout works by probabilistically removing, or â€śdropping out,â€ť inputs to a layer, which may be input variables in the data sample or activations from a previous layer.

Weight regularization is a strategy used to keep weights in the neural network small. The larger the network weights, the more complex the network is, and a highly complex network is more likely to overfit to the training data. This is because larger weights cause larger changes in output for smaller changes in inputs.

How to choose neural network model?To find the best learning rate, start with a very low value (10^-6) and slowly multiply it by a constant until it reaches a very high value (e.g. 10). Measure your model performance (vs the log of your learning rate) in your Weights and Biases dashboard to determine which rate served you well for your problem.

How to improve neural network model?The bias is a constant that we add, like an intercept to a linear equation. This gives the neural network an extra parameter to tune in order to improve the fit. The bias can be initialized to 0. Now, we need to define a function for forward propagation and for backpropagation.

There are several neural network architectures with different features, suited best for particular applications. Here, we are going to explore some of the most prominent architectures, particularly in context to deep learning. REGISTER>> Multilayer Perceptrons. Multilayer Perceptron (MLP) is a class of feed-forward artificial neural networks. The term perceptron particularly refers to a single neuron model that is a precursor to a larger neural network.

Why neural network black box model?A neural network is a black box in the sense that while it can approximate any function, studying its structure won't give you any insights on the structure of the function being approximated.

In the case of a Neural Network we are estimating linear parameters, and we are applying linear combinations with an activation or arguably equivalent "link function". So, unless somehow the composition of multiple GLMs stacked together doesn't qualify as a linear model anymore, it seems that this would make NN classify under a linear model ...
