The goal of image classification is to predict the categories of the input image using its features. This fact makes it suitable for application in classification methods. Input: An image with a single object, such as a photograph. This image shows the sigmoid function (or S-shaped curve) of some variable : The sigmoid function has values very close to either 0 or 1 across most of its domain. A typical classification method using the bag of words model consists of four steps as shown in Fig.1 In short, the bag of words model creates histograms of images which is used for classification. The iterative method starts with Otsu’s threshold and computes the mean values of the two classes as separated by the threshold. This dataset consists of 60,000 tiny images that are 32 pixels high and wide. What this is telling you is that the model has not seen enough examples of the rare class to be able to distinguish them from the common class. So we need more systematic ways to collect data. It is composed of images that are handwritten digits (0-9), split into a training set of 50,000 images and a test set of 10,000 where each image is of 28 x 28 pixels in width and height.
