Query: The ASHRAE Great Energy Predictor III competition: Overview and results   In late 2019, ASHRAE hosted the Great Energy Predictor III (GEPIII) machine
learning competition on the Kaggle platform. This launch marked the third
energy prediction competition from ASHRAE and the first since the mid-1990s. In
this updated version, the competitors were provided with over 20 million points
of training data from 2,380 energy meters collected for 1,448 buildings from 16
sources. This competition's overall objective was to find the most accurate
modeling solutions for the prediction of over 41 million private and public
test data points. The competition had 4,370 participants, split across 3,614
teams from 94 countries who submitted 39,403 predictions. In addition to the
top five winning workflows, the competitors publicly shared 415 reproducible
online machine learning workflow examples (notebooks), including over 40
additional, full solutions. This paper gives a high-level overview of the
competition preparation and dataset, competitors and their discussions, machine
learning workflows and models generated, winners and their submissions,
discussion of lessons learned, and competition outputs and next steps. The most
popular and accurate machine learning workflows used large ensembles of mostly
gradient boosting tree models, such as LightGBM. Similar to the first predictor
competition, preprocessing of the data sets emerged as a key differentiator.
