WebbPerceptron is a classification algorithm which shares the same underlying implementation with SGDClassifier. In fact, Perceptron () is equivalent to SGDClassifier (loss="perceptron", eta0=1, learning_rate="constant", penalty=None). Webb18 okt. 2024 · Step 3: Training the model. Now, it’s time to train some prediction models using our dataset. Scikit-learn provides a wide range of machine learning algorithms that have a unified/consistent interface for fitting, predicting accuracy, etc. The example given below uses KNN (K nearest neighbors) classifier.
