Svm classifier mostly used in addressing multi-classification problems. How to use MLP Classifier and Regressor in Python? How to Make an Image Classifier in Python using Tensorflow 2 and Keras Building and training a model that classifies CIFAR-10 dataset images that were loaded using Tensorflow Datasets which consists of airplanes, dogs, cats and other 7 objects using Tensorflow 2 and Keras libraries in Python. Here some steps by which we can implement MLPClassifier with Python. This allows you to save your model to file and load it later in order to make predictions. Unlike other classification algorithms such as Support Vectors or Naive Bayes Classifier, MLPClassifier relies on an underlying Neural Network to perform the task of classification. You will also receive a free Computer Vision Resource Guide. You can find full python source code and references below. This code works okay and achieves around 91.5% accuracy on test data.
