Research on EV loads clustering analysis method for source-grid-load system
Energy Reports, 2022 This report does some work on big data analysis of EV loads and extends automatic generation control (AGC) to automatic active power control (APC) by combining the current operating conditions of the grid and the spatial and temporal distribution ...

Mining Unclassified Traffic Using Automatic Clustering Techniques [PDF]
, 2011 In this paper we present a fully unsupervised algorithm to identify classes of traffic inside an aggregate. The algorithm leverages on the K-means clustering algorithm, augmented with a mechanism to automatically determine the number of traffic clusters.

Transactions of the International Society for Music Information Retrieval, 2022 We implement a novel approach to automatic harmonic analysis using a clustering method on pitch-class vectors (chroma vectors). The advantage of this method is its lack of top-down assumptions, allowing us to objectively validate the basic music theory ...

Automatic Clustering in Hyrise
, 2021 Physical data layout is an important performance factor for modern databases. Clustering, i.e., storing similar values in proximity, can lead to performance gains in several ways. We present an automated model to determine beneficial clustering columns and a clustering algorithm for the column-oriented, memory-resident database Hyrise. To automatically

Ellipsoidal K-Means: An Automatic Clustering Approach for Non-Uniform Data Distributions
AlgorithmsTraditional K-means clustering assumes, to some extent, a uniform distribution of data around predefined centroids, which limits its effectiveness for many realistic datasets.
