![]() The digits have been size-normalized and centered in a fixed-size image (28x28 pixels) with values from 0 to 1. The dataset contains 55,000 examples for training, 5,000 examples for validation and 10,000 examples for testing. MNIST is kind of benchmark of datasets for deep learning and is easily accesible through Tensorflow If you are into machine learning, you might have heard of this dataset by now. MNIST is a dataset of handwritten digits. We will start with importing the required Python libraries.įor this tutorial we use the MNIST dataset. 1- Sample Neural Network architecture with two layers implemented for classifying MNIST digits 0. The implemented network has 2 hidden layers: the first one with 200 hidden units (neurons) and the second one (also known as classifier layer) with 10 (number of classes) neurons.įig. Like before, we're using images of handw-ritten digits of the MNIST data which has 10 classes (i.e. The structure of the neural network that we're going to implement is as follows. Neural Networks Part 3: Learning and Evaluation Neural Networks Part 2: Setting up the Data and the Loss Neural Networks Part 1: Setting up the Architecture If you want to know more about the Neural Nets we suggest you to take this amazing course on machine learning or check out the following tutorials: We assume that you have the basic knowledge over the concept and you are just interested in the Tensorflow implementation of the Neural Nets. The key advantage of this model over the Linear Classifier trained in the previous tutorial is that it can separate data which is NOT linearly separable. ![]() In this tutorial, we'll create a simple neural network classifier in TensorFlow.
