This paper presents a method for learning time-varying higher-order interactions based on node observations, with application to short-term traffic forecasting based on traffic flow sensor measurements. We incorporate domain knowledge into the design of a new damped periodic kernel which leverages traffic flow patterns towards better structure learning. We introduce location-based regularization for...
Lovász introduced the theta function in his seminal paper [23] giving his celebrated solution to the problem of computing the Shannon capacity of the pentagon. Since then, the Lovász theta function has come to play a central role in information theory, graph theory and combinatorial optimization [11, 10], indeed Goemans [10] was led to remark: “it seems all paths lead to ϑ!”. The definition of the...
