A competition for energy disaggregation algorithms | Jack Kelly

A message from my good friend and colleague Jack Kelly: Source: A competition for energy disaggregation algorithms | Jack Kelly Now that I’ve (finally!) submitted my PhD thesis, I can focus on designing and implementing a competition for energy disaggregation algorithms. EDF Energy have kindly given me post-doc funding from now until the end of… Read More

Load Disaggregation Based on Aided Linear Integer Programming

Today I found out that a journal paper I helped co-author with colleagues Md. Zulfiquar Ali Bhotto and Ivan V. Bajić. Titled Load Disaggregation Based on Aided Linear Integer Programming it will be published in journal IEEE Transactions on Circuits and Systems II: Express Briefs. Here is the paper abstract: Load disaggregation based on aided linear integer programming (ALIP) is proposed.… Read More

Investigating the Switch Continuity Principle Assumed in Non-Intrusive Load Monitoring (NILM)

My paper about the Switch Continuity Principle in NILM has been accepted at the 29th Annual IEEE Canadian Conference on Electrical and Computer Engineering (CCECE 2016). Here is the abstract: Non-Intrusive Load Monitoring (NILM) researchers have always assumed the switch continuity principle (SCP), which assumes that only one appliance ever changes state at any given point in… Read More

Exploiting HMM Sparsity to Perform Online Real-Time Nonintrusive Load Monitoring (NILM)

Today, I learnt that my journal paper was accepted for publication in IEEE Transactions on Smart Grid (TSG) wich has an impact factor of 4.25. Co-authors were Fred Popowich, Ivan V. Bajic, Bob Gill, and Lyn Bartram. This paper is an expansion of my PhD thesis which and discusses an improved HMM-based NILM algorithm. Here is… Read More

Appliance Water Disaggregation via Non-Intrusive Load Monitoring (NILM)

Last week, I learnt that a paper Bradley Ellert, myself, and Fred Popowich wrote was accepted for presentation at the EAI International Conference on Big Data and Analytics for Smart Cities in Toronto October 13 to 14. Here is the abstract: The world’s fresh water supply is rapidly dwindling. Informing homeowners of their water use patterns can… Read More

Leveraging Submetered Electricity Loads to Disaggregate Household Water-Use

It is with great excitement to announce that Bradley Ellert successfully defended his Masters thesis on water disaggregation (NILM) last week. Titled Leveraging Submetered Electricity Loads to Disaggregate Household Water-Use, his thesis is now online for downloading. I helped mentor Bradley and provided advice for him on NILM and AMPds. I am very proud of the work he… Read More

NILM performance evaluation code released

Today I have publicly released the functions used to measure the accuracy performance in my journal paper Nonintrusive load monitoring (NILM) performance evaluation: A unified approach for accuracy reporting in Springer’s Energy Efficiency Journal (DOI 10.1007/s12053-014-9306-2). The Python 3 code is available in my GitHub repository.
