Question
What are some common algorithms used in classification?
Solution
Sure, here are some common algorithms used in classification:
-
Logistic Regression: This is a statistical method for predicting binary classes. The outcome or target variable is dichotomous in nature meaning there are only two possible outcomes.
-
Decision Tree: This is a type of supervised learning algorithm that is mostly used for classification problems. It works for both categorical and continuous input and output variables.
-
Random Forest: This is a type of ensemble learning method, where a group of weak models combine to form a powerful model. In Random Forest, we grow multiple trees as opposed to a single tree in CART model (see below). To classify a new object based on attributes, each tree gives a classification and we say the tree "votes" for that class. The forest chooses the classification having the most votes.
-
Support Vector Machine (SVM): This is a classification method. In this algorithm, we plot each data item as a point in n-dimensional space (where n is number of features you have) with the value of each feature being the value of a particular coordinate.
-
Naive Bayes: This is a classification technique based on Bayes’ theorem with an assumption of independence between predictors. In simple terms, a Naive Bayes classifier assumes that the presence of a particular feature in a class is unrelated to the presence of any other feature.
-
K-Nearest Neighbors (KNN): This is a simple algorithm that stores all available cases and classifies new cases based on a similarity measure (e.g., distance functions).
-
Gradient Boosting algorithms: GBM, XGBoost, LightGBM, CatBoost, etc. These are boosting algorithms used in classification (and regression) tasks which produce a prediction model in the form of an ensemble of weak prediction models, typically decision trees.
-
Neural Networks: These are a set of algorithms, modeled loosely after the human brain, that are designed to recognize patterns. They interpret sensory data through a kind of machine perception, labeling or clustering raw input.
These are just a few examples, and there are many other algorithms used for classification tasks.
