Preprocess Data
Data preprocessing is crucial for building a robust model. In this step, we’ll create a recipe to preprocess the data. In our case, we don’t need any preprocessing since the Iris dataset is well-structured and doesn’t have any missing values.
R
# Create a recipe for data preprocessing preprocess_recipe <- recipe (Species ~ ., data = iris) |
Predictions Multiple outcomes with KNN Model Using tidymodels
When dealing with classification problems that involve multiple classes or outcomes, it’s essential to have a reliable method for making predictions. One popular algorithm for such tasks is k-Nearest Neighbors (k-NN). In this tutorial, we will walk you through the process of making predictions with multiple outcomes using a k-NN model in R, specifically with the tidymodels framework.
K-Nearest Neighbors (KNN) is a simple yet effective supervised machine learning algorithm used for classification and regression tasks. Here’s an explanation of KNN and some of its benefits:
