Simple and Straightforward Classification with Extreme Gradient Boosting

Sep 25, 2023 | ywu120766.medium.com | Yanan Wu

XGboost is a tree-based algorithm in the supervised branch of Machine Learning. Unlike Gradient Boosting, XGBoost builds trees using the similarity score and Gain to determine the best node splits. Step 1: Input dataset {xᵢ, yᵢ} from i = 1 to n = 4. Step 2. We assign the initial prediction as 0.5. 0.5 is the default value in the XGBoost module. Thus, the initial residual is the difference between observing y and y_initial. Step 3.
Gradient Boost - Classification

Sep 24, 2023 | ywu120766.medium.com | Yanan Wu

Input data: (xᵢ,yᵢ) from i=1 to n, xᵢ is the x variable (Near school, Build Year, Parking lot) in the dataset, and yᵢ is the dependent variable (Price) in the dataset. Step 1: Gradient Boost construct each tree based on the relationship between residuals and x variables. So we must establish a Pseudo Residual (initial prediction) for the first constructed tree. In the classification task, it will be the log(odds) of the dependent variable (Figure 1).

Hyperplane and Maximal Margin Classifier (Part 01)

Jun 17, 2023 | medium.com | Yanan Wu

In n-dimension space, a hyperplane is a flat affine subspace with an n-1 dimension. For instance, in 2-dimension space, a hyperplane is a 1-dimensional line (Figure 1). The mathematical definition of a 2-dimension hyperplane is simple and defined by the equation (1.1)In the p-dimensional space, the dimension of the hyperplane is p-1, as illustrated in equation (1.2)2. Classification using a hyperplaneA hyperplane (black solid line: 2+3 * x_1 + 2 * x_2 = 0 (Equ.
