Linear discriminant analysis is a method you can use when you have a set of predictor variables and you’d like to classify a response variable into two or more classes. This tutorial provides a step-by-step example of how to perform linear discriminant analysis in Python. Step 1: Load Necessary … Meer weergeven For this example, we’ll use the irisdataset from the sklearn library. The following code shows how to load this dataset and convert it to a pandas DataFrame to make it easy to work with: We can see that the dataset … Meer weergeven Next, we’ll fit the LDA model to our data using the LinearDiscriminantAnalsyisfunction from sklearn: Meer weergeven Lastly, we can create an LDA plot to view the linear discriminants of the model and visualize how well it separated the three different species in our dataset: You can find the complete Python code used in this tutorial here. Meer weergeven Once we’ve fit the model using our data, we can evaluate how well the model performed by using repeated stratified k-fold cross validation. For this example, we’ll use 10 folds and 3 repeats: We can see that the … Meer weergeven Web8 aug. 2024 · With some research , today I want to discuss few techniques helpful for unsupervised text classification in python.
