Classification models are used in machine learning to predict the category or class that a new data point belongs to based on the features of the data. It is a type of supervised learning algorithm where the model is trained on a labeled dataset and then used to make predictions on new, unseen data.
Here are some common classification models:
1. Logistic Regression
2. Support Vector Machines (SVM)
3. Decision Trees
4. Random Forest
5. Naive Bayes
6. K-Nearest Neighbors (KNN)
7. Neural Networks
To evaluate the performance of a classification model, various metrics such as accuracy, precision, recall, F1 score, and area under the ROC curve can be used. Additionally, techniques like cross-validation and hyperparameter tuning can be employed to improve the model's performance.
When evaluating a classification model, it is important to consider the specific requirements of the problem at hand and choose a model that best fits those requirements.
