K-means algorithm has long been a staple in machine learning and data mining fields, primarily for its effectiveness in clustering large-scale datasets. However, traditional K-means clustering doesn't inherently distinguish the varying discriminative power of features in data. To address this, the paper proposes an innovative clustering framework incorporating L2-norm regularization on feature weights, thereby enhancing clustering outcomes. This new approach builds on the Weighted K-means (W-K-means) algorithm by applying L2-norm regularization to feature weights, effectively balancing feature importance. For numerical datasets, this framework introduces the l2-Wkmeans algorithm, which uses conventional means as cluster centers. For categorical datasets, two variations—l2-NOF (Non-numeric features based on different smoothing modes) and l2-NDM (Non-numeric features based on distance metrics)—are proposed. The essence of these methods lies in their updated clustering objective function and derived update rules for cluster centers, membership matrices, and feature weights. Extensive experiments demonstrate the superior performance of the proposed algorithms on both numerical and categorical datasets. These methods exhibit advantages such as improved clustering accuracy, robustness to noisy data, and adaptability to high-dimensional data environments. This signifies that incorporating L2-norm regularization for feature weighting substantially enhances the clustering quality of K-means, especially for complex, high-dimensional datasets. Additionally, the study discusses the impact of regularization parameters on clustering performance, offering practical insights for tuning these parameters to optimize clustering results. This guidance allows users to select the appropriate regularization intensity based on task-specific and data-related characteristics. The research provides a fresh perspective on improving the K-means clustering algorithm by emphasizing feature importance through L2-norm regularization, enhancing both clustering power and generalizability. This method is valuable for large-scale datasets and scenarios that require nuanced feature differentiation, representing a significant step forward in clustering quality and advancing related research fields.

Energy Control Problem Code in MATLAB: Non-Intrusive Load Monitoring (NILM) for HVAC Systems This repository contains the dataset we collected for HVAC energy disaggregation, as well as the source code and demonstrations from our paper in IEEE Transactions on Power Systems. To the best of our knowledge, this is the first dataset collected for studying Non-Intrusive Load Monitoring (NILM) applied to Heating, Ventilation, and Air Conditioning (HVAC) systems. Energy disaggregation or Non-Intrusive Load Monitoring (NILM) addresses the problem of extracting device-level energy consumption information by monitoring the aggregated signal at a single measurement point, without the need to install meters on each individual device. This can be framed as a source separation problem where the aggregated signal is represented as a linear combination of the basic vectors in a matrix factorization framework. In this work, we utilize machine learning to predict the energy consumption pattern of each device over the course of a day. The project is part of our collaboration with [institution name]. Prerequisites: MATLAB R2015a Datasets (Temporarily unavailable. Will be available once the required permissions are granted. Apologies for the inconvenience!) Experiments We designed two different experiments to evaluate our proposed algorithm. The first experiment disaggregates the energy of the entire household into the energy consumption of all devices within the home.
