On modeling NP-Complete problems as polynomial-sized linear programs: Escaping/Side-stepping the "barriers"
Moustapha Diaby, Mark Karwan, Lei Sun
In view of the extended formulations (EFs) developments (e.g. "Fiorini, S., S. Massar, S. Pokutta, H.R. Tiwary, and R. de Wolf [2015]. Exponential Lower Bounds for Polytopes in Com…
Adversarial Balancing-based Representation Learning for Causal Effect Inference with Observational Data
Xin Du, Lei Sun, Wouter Duivesteijn +2
Learning causal effects from observational data greatly benefits a variety of domains such as health care, education and sociology. For instance, one could estimate the impact of a…
On modeling hard combinatorial optimization problems as linear programs: Refutations of the "unconditional impossibility" claims
Moustapha Diaby, Mark H. Karwan, Lei Sun
There has been a series of developments in the recent literature (by essentially a same "circle" of authors) with the absolute/unconditioned (implicit or explicit) claim that there…
On "Exponential Lower Bounds for Polytopes in Combinatorial Optimization" by Fiorini et al. (2015): A Refutation For Models With Disjoint Sets of Descriptive Variables
Moustapha Diaby, Mark H. Karwan, Lei Sun
We provide a numerical refutation of the developments of Fiorini et al. (2015)* for models with disjoint sets of descriptive variables. We also provide an insight into the meaning…
