The “classic” application of logistic regression model is binary classification. However, we can also use “flavors” of logistic to tackle multi-class classification problems, e.g., using the One-vs-All or One-vs-One approaches, via the related softmax regression / multinomial logistic regres...

Perceptron is a simple model of a biological neuron used for supervised learning of binary classifiers. Learn about perceptron working, components, types and more.
Binary classification: The input variables are segregated into two groups. Multiclass/Multinomial classification: The input variables are classified into three or more groups. Multilabel classification: Multiclass is generalized as multilabel.Supervised Learning is one of type of Machine Learning. Enroll...
in a binary classification problem, majority voting takes predictions from each base classifier for a given data instance and uses the majority prediction as the end prediction. Weighted majority voting is an extension of this technique that gives greater weight to certain learner’s predictions over...
Maximum Entropy Classifier, or just Multi-class Logistic Regression) is a generalization of logistic regression that we can use for multi-class classification (under the assumption that the classes are mutually exclusive). In contrast, we use the (standard) Logistic Regression model in binary classif...
TensorFlow Binary Classification: Linear Classifier Example Advantages of Keras Fast Deployment and Easy to understand Keras is very quick to make a network model. If you want to make a simple network model with a few lines, Python Keras can help you with that. Look at the Keras example below...
OvA is a technique for multiclass classification using SVMs. It trains a binary SVM classifier for each class, treating it as the positive class and all other classes as the negative class. One-vs-One OvO is a technique for multiclass classification using SVMs. It trains a binary SVM classi...
A standard confusion matrix template for a binary classifier may look like this: The top-left box provides the number of true positives (TP), being the number of correct predictions for the positive class. The box beneath it is false positives (FP), those negative-class instances incorrectly ...
In this blog, we saw ‘What is Gradient Boosting?,’ AdaBoost, XGBoost, and the techniques used for building gradient boosting machines. Also, we implemented the boosting classifier and compared the accuracy of the model for different learning rates. This is all about how the gradient boosting...
