Key Terms

Classification
A machine learning task of predicting the category of an object based on its features.

Example: Classifying emails as spam or not spam.

Feature
An individual measurable property or characteristic of a phenomenon being observed.

Example: Sepal length in the Iris Dataset.

k-Nearest Neighbors (k-NN)
A simple algorithm that classifies data points based on the classes of their nearest neighbors.

Example: Using k-NN to classify a new iris flower based on its features.

Accuracy
The ratio of correctly predicted instances to the total instances in the dataset.

Example: An accuracy of 90% means 90 out of 100 predictions were correct.

Confusion Matrix
A table used to evaluate the performance of a classification model by comparing predicted and actual values.

Example: A confusion matrix showing true positives, false positives, true negatives, and false negatives.

Scatter Plot
A graphical representation of two variables, showing their relationship using dots.

Example: A scatter plot of petal length vs. petal width.
