This month I found out that a conference paper I helped co-author with colleagues Chinthaka Dinesh and Ivan V. Bajić. Titled Time-Of-Day Usage Patterns Into Non-Intrusive Load Monitoring, it will be presented at the 5th IEEE Global Conference on Signal and Information Processing (GlobalSIP) this November in Montreal, Canada. Here is the paper abstract:
Understanding appliance power consumption can help occupants optimize their power consumption behaviour. One popular class of methods for determining appliance power consumption is known as non-intrusive load monitoring (NILM). This paper shows how to incorporate time-of-day appliance usage patterns into a recent NILM method, resulting in both improved accuracy and reduction in computational complexity.
Keywords: non-intrusive load monitoring (NILM), time-of-day usage, smart grid, load disaggregation, graph spectral representation
