Experimental observation of oscillating and interacting matter wave dark solitons
Oscillation dark soliton well pairs of bose-einstein condensate harmonic trap particle image
2014/12/25
We report on the generation, subsequent oscillation and interaction of a pair of matter-wave dark solitons. These are created by releasing a Bose-Einstein condensate from a double well potential into ...
Approximate Inference for Observation Driven Time Series Models with Intractable Likelihoods
Observation Driven Time Series Models Approximate Bayesian Computation Asymptotic Con-sistency Markov Chain Monte Carlo
2013/4/28
In the following article we consider approximate Bayesian parameter inference for observation driven time series models. Such statistical models appear in a wide variety of applications, including eco...
State-Observation Sampling and the Econometrics of Learning Models
Hidden Markov model particle filter state-observation sampling learning indirect inference forecasting state space model value at risk
2011/6/20
In nonlinear state-space models, sequential learning about the hidden state can proceed
by particle filtering when the density of the observation conditional on the state is available
analytically (...

Appealing to several multivariate information measures|some familiar, some new here|we ana-
lyze the information embedded in discrete-valued stochastic time series. We dissect the uncertainty

Data-Efficient Change Detection On-Off Observation Control
2011/6/16
In the classical version of the Bayesian quickest change detection problem proposed by Shiryaev,
there is a sequence of observations whose distribution changes at a random time, and the goal is to
m...
A generalized Law of the Iterated Logarithm for the largest observation of a triangular array
Almost sure convergence weak law of large numbers law of the iterated logarithm

Consider independent and identically distributed random
variables (X, XRj, I < j < k, k > 1) from a particular distribution
with EX = oo. We show that there exists an unusual generalized
Law of the...
