What is hidden layer How does hidden layer help in solving XOR problem using Multilayer perceptron?
The hidden layer allows for non-linearity. A node in the hidden layer isn’t too different to an output node: nodes in the previous layers connect to it with their own weights and biases, and an output is computed, generally with an activation function.
How to create a neural network for the function XOR?
We will now create a neural network with two neurons in the hidden layer and we will show how this can model the XOR function. However, we will write code that will allow the reader to simply modify it to allow for any number of layers and neurons in each layer, so that the reader can try simulating different scenarios.
Which is the correct activation function for XOR problem?
The activation function in output layer is selected based on the output space. For a binary classification task sigmoid activations is correct choice while for multi class classification softmax is the most populary choice. In our X-OR problem, output is either 0 or 1 for each input sample. So, it is a two class or binary classification problem.
How is the XOR function condensed into two parts?
The XOR function can be condensed into two parts: a NAND and an OR. If we can calculate these separately, we can just combine the results, using an AND gate. Let’s call the OR section of the formula part I, and the NAND section as part II. We’ll use the same Perceptron class as before, only that we’ll train it on OR training data.
How to solve the XOR problem by Aniruddha?
Let’s replace A and B with x_1 and x_2 respectively since that’s the convention we’re using in our data. The XOR function can be condensed into two parts: a NAND and an OR. If we can calculate these separately, we can just combine the results, using an AND gate. Let’s call the OR section of the formula part I, and the NAND section as part II.
