1 code implementation31 Mar 2024 Chun Fu, Hussain Kazmi, Matias Quintana, Clayton Miller

Thus, the study proposes a conditional diffusion model for generating high-quality synthetic energy data using relevant metadata.

Opening the Black Box: Towards inherently interpretable energy data imputation models using building physics insight

1 code implementation28 Nov 2023 Antonio Liguori, Matias Quintana, Chun Fu, Clayton Miller, Jérôme Frisch, Christoph van Treeck

While no significant improvement is observed in terms of reconstruction error with the proposed PI-DAE, its enhanced robustness to varying rates of missing data and the valuable insights derived from the physics-based coefficients create opportunities for wider applications within building systems and the built environment.

no code implementations7 Feb 2022 Clayton Miller, Liu Hao, Chun Fu

The ASHRAE Great Energy Predictor III (GEPIII) competition was held in late 2019 as one of the largest machine learning competitions ever held focused on building performance.

Using Google Trends as a proxy for occupant behavior to predict building energy consumption

1 code implementation31 Oct 2021 Chun Fu, Clayton Miller

In recent years, the availability of larger amounts of energy data and advanced machine learning algorithms has created a surge in building energy prediction research.

Limitations of machine learning for building energy prediction: ASHRAE Great Energy Predictor III Kaggle competition error analysis

1 code implementation25 Jun 2021 Clayton Miller, Bianca Picchetti, Chun Fu, Jovan Pantelic

Higher magnitude (out-of-range) errors (RMSLE_scaled > 0. 3) occur in 4. 8% of the test data and are unlikely to be accurately predicted.
