In this paper we propose a robust simple linear regression method, namely the smooth adaptwe line (SAL), which divides the data set into three equal groups on the basis of the ordered values of the explanatory

We present the first efficient and provably consistent estimator for the robust regression problem. The area of robust learning and optimization has generated a significant amount of interest in the learning and statistics communities in recent years owing to its applicability in scenarios with corrupted...
Specifically, predictive mean matching (pmm) is utilized for numeric variables, logistic regression (logreg) for factor variables with two levels, multinomial logit model (polyreg) for factor variables with more than two levels, and ordered logit model (polr) for ordered variables with multiple ...

We employed five machine learning algorithms: Logistic Regression (LR), XGBoost (XGB), Multilayer Perceptron (MLP), Naive Bayes (NB), and Random Forest (RF). All feature selection processes, and machine learning classification pipelines were implemented using an in-house developed tool based on ...

Kendall transformation is a conversion of an ordered feature into a vector of pairwise order relations between individual values. This way, it preserves ranking of observations and represents it in a categorical form. Such transformation allows for gener
In this post, we will explore CatBoost’s unique features, such as Symmetric Trees and Ordered Boosting, and compare different configurations. You’ll learn how to implement CatBoost for regression, prepare data effectively, and analyze feature importance. Whether you’re a data sc...
