Query: State-of-the-art predictive and prescriptive analytics for IEEE CIS 3rd
  Technical Challenge   In this paper, we describe our proposed methodology to approach the
predict+optimise challenge introduced in the IEEE CIS 3rd Technical Challenge.
The predictive model employs an ensemble of LightGBM models and the
prescriptive analysis employs mathematical optimisation to efficiently
prescribe solutions that minimise the average cost over multiple scenarios. Our
solutions ranked 1st in the optimisation and 2nd in the prediction challenge of
the competition.
