Nettet1. jul. 2024 · First, we'll generate random classification dataset with make_classification () function. The dataset contains 3 classes with 10 features and the number of samples is 5000. x, y = make_classification (n_samples =5000, n_features =10, n_classes =3, n_clusters_per_class =1) Then, we'll split the data into train and test parts. Nettet13. jul. 2024 · As an example, the popular dataset House Prices: Advanced Regression Techniques from Kaggle has about 80 features and more than 20% of them contain some level of missing data. In that case, you might need to spend some time understanding the attributes and imputing missing values.

Step 3 − Plot the training instances using matplotlib.
NettetThe Perceptron is a linear classification algorithm. This means that it learns a decision boundary that separates two classes using a line (called a hyperplane) in the feature space. As such, it is appropriate for those problems where the classes can be separated well by a line or linear model, referred to as linearly separable. Nettet18. apr. 2024 · Developed a linear regression classifier for a 3-class example, which was subject to masking. Found that LDA is a very powerful tool for well behaved Gaussian datasets. Extended into QDA for a slightly more flexible but more expensive method for less well-behaved datasets. Comments & feedback appreciated!
