- Jun 19, 2019 · While logistic regression is targeting on the probability of events happen or not, so the range of target value is [0, 1]. Perceptron uses more convenient target values t=+1 for first class and t=-1 for second class. Therefore, the algorithm does not provide probabilistic outputs, nor does it handle K>2 classification problem. #NeuralNetworks #BackPropogation #ScikitLearn #MachineLearning Neural Networks also called Multi Layer perceptrons in scikit learn library are very popular w...
- Logistic regression, in spite of its name, is a model for classification, not for regression.. Although the perceptron model is a nice introduction to machine learning algorithms for classification, its biggest disadvantage is that it never converges if the classes are not perfectly linearly separable. machine-learning documentation: Classification in scikit-learn. Example. 1. Bagged Decision Trees. Bagging performs best with algorithms that have high variance.
