Prediction of Large Events in Directed Sandpiles
Dhruv Shah
The degree of predictability of large avalanche events in the directed sandpile model is studied. A waiting time based prediction strategy which exploits the local anticorrelation…
Controller Design for Bilinear Neural Feedback Loops
Dhruv Shah, Jorge Cortés
This paper considers a class of bilinear systems with a neural network in the loop. These arise naturally when employing machine learning techniques to approximate general, non-aff…
Non Gaussian statistics in static and dynamic Galton boards
Dhruv Shah, R. K. Shishir, Manjaree +3
Perturbing the arrangements of pegs on a static Galton board can result in non-trivial stationary distributions, which in the continuum limit correspond to departure from regular g…
An Optimistic-Robust Approach for Dynamic Positioning of Omnichannel Inventories
Pavithra Harsha, Shivaram Subramanian, Ali Koc +4
We introduce a new class of data-driven and distribution-free optimistic-robust bimodal inventory optimization (BIO) strategy to effectively allocate inventory across a retail chai…
