We test for improvement in performance over the TPO v1 Support Vector Machine regression model (SVR) by building an Ensemble of ML algorithms. The key improvement for ensemble is that it will anticipate a concept drift in the data and will select the model that is expected to perform the best for the following day. First, the addition of a Hidden M...

Recommender in TPO II works by learning from how the building is operated. This has shortcomings. It learns from past operators ‘ decisions. Are those decisions the best in terms of building operation objectives? The algorithms we use now to produce recommendations do not factor the uncertainty of the inputs and forecasts, e.g. weather (temp, hum...
