no code implementations3 Feb 2024 Wei Sun, Scott McFaddin, Linh Ha Tran, Shivaram Subramanian, Kristjan Greenewald, Yeshi Tenzin, Zack Xue, Youssef Drissi, Markus Ettl

The first challenge is caused by the limitations of observational data for accurate causal inference which is typically a prerequisite for good decision-making.

An Optimistic-Robust Approach for Dynamic Positioning of Omnichannel Inventories

no code implementations17 Oct 2023 Pavithra Harsha, Shivaram Subramanian, Ali Koc, Mahesh Ramakrishna, Brian Quanz, Dhruv Shah, Chandra Narayanaswami

Using a real-world dataset from a large American omnichannel retail chain, a business value assessment during a peak period indicates over a 15% profitability gain for BIO over RO and other baselines while also preserving the (practical) worst case performance.

Scalable Optimal Multiway-Split Decision Trees with Constraints

no code implementations14 Feb 2023 Shivaram Subramanian, Wei Sun

However, existing MIP methods that build on an arc-based formulation do not scale well as the number of binary variables is in the order of $\mathcal{O}(2^dN)$, where $d$ and $N$ refer to the depth of the tree and the size of the dataset.

Constrained Prescriptive Trees via Column Generation

no code implementations20 Jul 2022 Shivaram Subramanian, Wei Sun, Youssef Drissi, Markus Ettl

We introduce a novel path-based mixed-integer program (MIP) formulation which identifies a (near) optimal policy efficiently via column generation.
