In this paper, we propose the first exact inference algorithm for SBNs, based on compiling a given SBN to a Probabilistic Sentential Decision Diagram (PSDD). We further identify a tractable subclass of SBNs, which have PSDDs of polynomial size. These SBNs yield a tractable model of route distributions, whose structure can be learned from GPS data, using a simple algorithm that we propose. Empirically, we demonstrate the utility of our inference algorithm, showing that it can be an order-ofmagnitude more efficient than more traditional approaches to exact inference. We demonstrate the utility of our learning algorithm, showing that it can learn more accurate models and classifiers from GPS data.</p>}, number={01}, journal={Proceedings of the AAAI Conference on Artificial Intelligence}, author={Shen, Yujia and Goyanka, Anchal and Darwiche, Adnan and Choi, Arthur}, year={2019}, month={Jul.}, pages={7957-7965} }
