What is a Classifier?

A classifier is a type of algorithm used in machine learning and statistics to categorize data into distinct classes or groups based on input features. It analyzes the characteristics of the data and assigns labels to new, unseen instances based on learned patterns from the training data. To summarize, a classifier is an essential tool in data analysis that helps in organizing information into specific categories. It operates by examining various attributes of the data and utilizing these insights to predict the class of new data points. By understanding how classifiers function, we can better appreciate their role in tasks such as image recognition, spam detection, and medical diagnosis.
