High-Order Optimization of Gradient Boosted Decision Trees

no code implementations21 Nov 2022 Jean Pachebat, Sergei Ivanov

Unlike neural networks with millions of trainable parameters, GBDTs optimize loss function in an additive manner and have a single trainable parameter per leaf, which makes it easy to apply high-order optimization of the loss function.

In today's world, the presence of online disinformation and propaganda is more widespread than ever.

Boost then Convolve: Gradient Boosting Meets Graph Neural Networks

1 code implementation ICLR 2021 Sergei Ivanov, Liudmila Prokhorenkova

Previous GNN models have mostly focused on networks with homogeneous sparse features and, as we show, are suboptimal in the heterogeneous setting.

Reinforcement Learning for Combinatorial Optimization: A Survey

no code implementations7 Mar 2020 Nina Mazyavkina, Sergey Sviridov, Sergei Ivanov, Evgeny Burnaev

Many traditional algorithms for solving combinatorial optimization problems involve using hand-crafted heuristics that sequentially construct a solution.
