More features is not always better. As dimensionality grows, data becomes sparse, models overfit, and visualisation becomes impossible. PCA compresses many features into a few powerful components — ...

Accurate active power prediction in photovoltaic (PV) systems installed at extreme altitudes above 3800 m a.s.l. faces critical challenges due to non-stationary climate variability, monitoring ...
This study aims to improve survival modeling in head and neck cancer (HNC) by integrating patient-reported outcomes (PROs) using dimensionality reduction techniques. PROs capture symptom severity ...
Abstract: We propose a dimension reduction method for classification problems with multiple classes by combining principal component analysis and a projection to the simplex of class centers. It is ...
When a dataset contains thousands¾or even millions¾of features, it is considered high-dimensional data. While more features may seem helpful, high dimensionality introduces several challenges in ...
PCA, CPCA and PBA all identified three dietary patterns, with a common “traditional southern Chinese” pattern high in rice and animal-based foods and low in wheat products and dairy. Only this pattern ...
ABSTRACT: Heart disease continues to be a major global cause of death, making the development of reliable prediction models necessary to enable early detection and treatment. Using machine learning to ...
Understanding the quantum control landscape (QCL) is important for designing effective quantum control strategies. In this study, we analyze the QCL for a single two-level quantum system (qubit) using ...
