A new research paper introduces a method for simultaneously estimating multiple discrete unimodal distributions, particularly useful for analyzing search behavior on real-world platforms. The approach incorporates prior knowledge of precedence relations by imposing stochastic order constraints, formulating the estimation as a mixed-integer convex quadratic optimization problem. Experiments indicate that this method can reduce Jensen-Shannon divergence by an average of 2.2% (up to 6.3%) with small sample sizes, while performing comparably to existing techniques when sufficient data is available.
