How To Handle Imbalanced Data In XGBoost Using scale_pos_weight In Python

In machine learning, we often come across datasets where the number of observations in one class significantly outweighs the other. This is known as imbalanced data. For instance, in a dataset of credit card transactions, the number of fraudulent transactions (positive class) is usually much smaller than the number of legitimate transactions (negative class). This is also an example of a binary classification task, which is a common type of machine learning problem....

How To Use XGBoost For Multi-Output Regression In Python

Multi-output regression is a machine learning task where we need to predict multiple outputs from a single set of inputs. Imagine you’re a financial analyst at an investment firm. Your job is to predict the future performance of various stocks to guide investment decisions. For each stock, you want to predict several outputs such as the expected return, the volatility (risk), and the correlation with other stocks or market indices....

How To Use XGBoost For Multiclass Classification In Python

Multiclass classification is a machine learning task where the output can belong to more than two classes. In other words, it can sort data into multiple categories. For example, a piece of fruit can be classified as an ‘apple’, ‘banana’, or ‘cherry’. Or, a car can be classified as ‘sedan’, ‘SUV’, or ’truck’. Just like binary classification, we can use a variety of algorithms to classify the data points into these multiple categories....

How To Use XGBoost For Binary Classification In Python

Binary classification is a type of machine learning task where the output is a binary outcome, i.e., it belongs to one out of two classes. For example, an email can be classified as either ‘spam’ or ’not spam’, or a tumor can be ‘malignant’ or ‘benign’. When you have more than two classes, it’s called multiclass classification. We can use various algorithms to classify the data points. These algorithms include logistic regression, decision trees, random forest, support vector machines, and gradient boosting algorithms like XGBoost....
