Abstract

This paper is concerned with statistical estimation of two preferential attachment models: the Buckley-Osthus model and the hierarchical preferential attachment model. We prove that the maximum likelihood estimates for both models are consistent. We perform simulation studies to corroborate our theoretical findings. We also apply both models to study the evolution of a real-world network. A list of open problems are presented., Comment: 12 pages, 2 figures, 4 tables. This paper is published by http://proceedings.mlr.press/v119/tang20b.html

Abstract

This is an expository article on the Poisson binomial distribution. We review lesser known results and recent progress on this topic, including geometry of polynomials and distribution learning. We also provide examples to illustrate the use of the Poisson binomial machinery. Some open questions of approximating rational fractions of the Poisson binomial are presented., Comment: 21 pages, 3 figures

Abstract

For the problem of intermittent posture adjustment is caused by design of the discontinuous parking path in the small parking space, a path planning method of combination of cycloid, arc and straight line is proposed, and the tracking deviation of the non-time reference variable is used to design sliding mode controller. First of all, requirement and restrictions during the parking process are considered to devise entry paths and adjustment paths. The vehicle with extreme posture is guided into the parking space by the entry path. Posture adjustment is implemented by a smooth combination of paths of adjustment paths in the parking space. Then, the sliding mode controller is designed with an exponential approach rate; continuous function is used to substitute symbolic function in the approach rate, the effects of jitter is reduced. The simulation results show that parking is finished continuously, small tracking error and outsanding jitter suppression is presented. [ABSTRACT FROM AUTHOR]
