Arnaud Doucet (University of Oxford)
online
Abstract: I will introduce Ensemble Rejection Sampling, a scheme for perfect simulation of a class of Feynmac-Kac models. In particular, this scheme allows us to sample exactly from the posterior distribution of the latent states of a class of non-linear non-Gaussian state-space models and from the distribution of a class of conditioned random walks. Ensemble Rejection Sampling relies on a high-dimensional proposal distribution built using ensembles of state samples and dynamic programming. Although this algorithm can be interpreted as a…

Ezra Tal (LIDS)
Online
ABSTRACT In recent years, autonomous unmanned aerial vehicles (UAVs) that can execute aggressive (i.e., fast and agile) maneuvers have attracted significant attention. We focus on the design of control algorithms for accurate tracking of such maneuvers. This problem is complicated by aerodynamic effects that significantly impact vehicle dynamics at high speeds. In contrast, typical multicopter controllers that operate at low speeds may neglect vehicle aerodynamics all together. We propose a sensor-based approach to account for high-speed aerodynamics. Our controller directly…

online
African cities are rapidly growing and laying down transportation infrastructure and systems with impacts well into the future. Exploring the politics of decision making in the sector and using Nairobi as a case study, this talk explores a "Digital Data Commons" approach to supporting more equitable and effective policies, planning and investments for African cities to avoid high emissions-low livability lock in. Join us for this conversation on urban development, data and planning with Dr. Jacqueline Klopp, Co-Director of the Center for Sustainable Development at Columbia…

Mary Wootters (Stanford University )
online
Abstract: What combinatorial properties are likely to be satisfied by a random subspace over a finite field? For example, is it likely that not too many points lie in any Hamming ball? What about any cube? We show that there is a sharp threshold on the dimension of the subspace at which the answers to these questions change from "extremely likely" to "extremely unlikely," and moreover we give a simple characterization of this threshold for different properties. Our motivation comes…
