To see this, calculate the derivative of the tanh function and notice that input values are in the range [0,1].The range of the tanh function is [-1,1] and that of the sigmoid function is [0,1]. Also known as the logistic function. This function graphed out looks like an ‘S’ which is where this function gets is name, the s is sigma in greek. Your network will output a prediction, y_hat which we will compare to the desired output of y. The gradient is the partial derivative of a function that takes in multiple vectors and outputs a single value (i.e. Used to calculate how far off your label prediction is. The sigmoid function has an interval of [0,1], while the ReLU has a range from [0, infinity]. Depending on how much data we have at hand, here are the different ways to leverage this: Learning rate The learning rate, often noted $\alpha$ or sometimes $\eta$, indicates at which pace the weights get updated.

Gradient checking Gradient checking is a method used during the implementation of the backward pass of a neural network. First, the cheat sheet will asks you about the data nature and then suggests the best algorithm for the job. Overfitting small batch When debugging a model, it is often useful to make quick tests to see if there is any major issue with the architecture of the model itself. The current most popular method is called Adam, which is a method that adapts the learning rate. Originally posted here in PDF format.

Neural networks are a class of models that are built with layers. Cross-entropy loss In the context of binary classification in neural networks, the cross-entropy loss $L(z,y)$ is commonly used and is defined as follows: Backpropagation Backpropagation is a method to update the weights in the neural network by taking into account the actual output and the desired output. It forces the model to avoid relying too much on particular sets of features. Neural Networks has various variants like CNN (Convolutional Neural Networks), RNN (Recurrent Neural Networks), AutoEncoders etc. Typically found in Recurrent Neural Networks but are expanding to use in others these are little “memory units” that keep state between inputs for training and help solve the vanishing gradient problem where after around 7 time steps an RNN loses context of the input prior.

This means that the sigmoid is better for logistic regression and the ReLU is better at representing positive numbers. Some times denoted by CE. Deep Learning Algorithms are inspired by brain function. Usually paired with cross entropy as the loss function. From time to time I share them with friends and colleagues and recently I have been getting asked a lot, so I decided to organize and share the entire collection. L1 can yield sparse models while L2 cannot. Docker Cheat Sheet for Deep Learning 2019. A function used to activate weights in our network in the interval of [0, 1]. By noting $\mu_B, \sigma_B^2$ the mean and variance of that we want to correct to the batch, it is done as follows: Epoch In the context of training a model, epoch is a term used to refer to one iteration where the model sees the whole training set to update its weights.
