Comparing four machine learning algorithms for household non-intrusive load monitoring

Energy and AI 2024年第3期17卷 206-219页

作者： Thomas Lee Young James gopsill Maria Valero Sindre Eikevåg Ben Hicks University of Bristol UK

The combination of Machine Learning (ML), smart energy meters, and availability of household appliance energy profile data has opened new opportunities for Non-Intrusive Load Monitoring (NILM). However, the number of options makes it challenging in selecting optimal combinations for different energy applications, which requires studies to examine their *** paper contributes one such study that investigated four established ML approaches – K Nearest Neighbour (KNN), Support Vector Machine (SVM), eXtreme gradient Boosting (XgBoost) and Convolutional Neural Network (CNN) – and their performance in classifying appliance events from Alternating Current (AC) and Root Mean Square (RMS) energy data where the sampling frequency and training dataset set size was varied (10 Hz–1 kHz and 50–2000 examples per class, respectively). The computational expense during training, testing and storage was also assessed and evaluated with reference to real-world *** CNN classifier trained on AC data at 500 Hz and 11,000 examples gave the best F1-score (0.989) followed by the KNN classifier (0.940). The storage size required by the CNN models was 3̃MB, which is very close to fitting on cost-effective embedded system microcontrollers. This would prevent high-rate data needing to be sent to the cloud as analysis could be performed on edge computing Internet-of-Things (IoT) devices.

Projective Hilbert modules and sequential approximations

引用

Science China Mathematics 2024年

作者： Lawrence g.Brown Huaxin Lin Department of Mathematics Purdue University Department of Mathematics East China Normal University Department of Mathematics University of Oregon

We show that when A is a separable C*-algebra, every countably generated Hilbert A-module is projective(with bounded module maps as morphisms). We also study the approximate extensions of bounded module maps. In the case where A is a σ-unital simple C*-algebra with strict comparison, and every strictly positive lower semicontinuous affine function on quasitraces can be realized as the rank of an element in the Cuntz semigroup, we show that the Cuntz semigroup is equivalent to unitarily equivalent classes of countably generated Hilbert A-modules if and only if A has stable rank one.
