Webb8 aug. 2016 · Implementing k-NN for image classification with Python. Now that we’ve discussed what the k-NN algorithm is, along with what dataset we’re going to apply it to, let’s write some code to actually perform image classification using k-NN. Open up a new file, name it knn_classifier.py , and let’s get coding: Webbmodel.add (Flatten ()) Add the fully connected layer or final layer, i.e., the output layer: #o/p layer. model.add (Dense (1,activation='sigmoid')) Sigmoid function has been used as this is a binary classification problem. ‘1’ indicates linear output.
