Abstract

Real-time data analytics based on machine learning algorithms for smart building energy management system is challenging. This chapter presents a fast machine-learning accelerator for real-time data analytics in smart micro-grid of buildings. A compact yet fast incremental least-squares-solver based learning algorithm is developed on computational resource limited IoT hardware. The compact accelerator mapped on FPGA can perform real-time data analytics with consideration of occupant behavior and continuously update prediction model with newly collected data. Experimental results have shown that our proposed accelerator has a comparable forecasting accuracy with an average speed-up of 4. 56× and 89. 05×, when compared to general CPU and embedded CPU implementation for load forecasting.
