Abstract
We present the results from our multi-wavelength monitoring campaign of the transient AT 2022wtn, discovered by the Zwicky Transient Facility in the nucleus of SDSS J232323.79+104107.7, the less massive galaxy in an active merging pair with a mass ratio of ∼10:1. AT 2022 ...

We use Church, a Turing-universal language
for stochastic generative processes and the probability
distributions they induce, to study and extend
several objects in nonparametric Bayesian statistics.
We connect exchangeability and de Finetti measures
with notions of purity and closures from fun ...

We describe a novel stochastic process that
can be used to construct a multidimensional
generalization of the stick-breaking process
and which is related to the classic stick breaking
process described by Sethuraman [1994]
in one dimension. We describe how the process
can be applied to relatio ...

Modern control theory has provided a large number of tools for dealing with probabilistic systems. However, most of these tools solve for local policies; there are relatively few tools for solving for complex plans that, for instance, gather information. In contrast, the planning community has provi ...

Active learning can be framed as a planning in information space problem: the goal is to learn about the world by taking actions that improve expected performance. In some domains, planning far into the future is prohibitively expensive and the agent is not able to discover effective information-gat ...

In the last few years, how robots operate in the world has advanced considerably. Examples include the autonomous vehicles in the DARPA Grand Challenges and Urban Challenge, the considerable work in robot mapping, and the growing interest in home and service robots. However, these example technologi ...

Many optimization problems that arise in science and engineering are those in which we only have a stochastic approximation to the underlying objective (e.g. estimation problems such as linear regression). That is, given some distribution $\mathcal{D}$ over functions $\psi$, we wish to minimize $P(x ...

We develop a family of accelerated stochastic algorithms that optimize sums of convex functions. Our algorithms improve upon the fastest running time for empirical risk minimization (ERM), and in particular linear least-squares regression, across a wide range of problem settings. To achieve this, we ...
