On a Class of Z+-Valued Autoregressive Moving Average (ARMA) Processes
Revstat Statistical Journal, 2008 A convolution semigroup of probability generating functions and its related operator ⊙F are used to construct a class of stationary Z+-valued autoregressive moving average (ARMA) processes.

A Neural Networks Committee for the Contextual Bandit Problem [PDF]
, 2014 This paper presents a new contextual bandit algorithm, NeuralBandit, which does not need hypothesis on stationarity of contexts and rewards. Several neural networks are trained to modelize the value of rewards knowing the context.

Cautious Gait during Navigational Tasks in People with Hemiparesis: An Observational Study
SensorsLocomotor and balance disorders are major limitations for subjects with hemiparesis. The Timed Up and Go (TUG) test is a complex navigational task involving oriented walking and obstacle circumvention. We hypothesized that subjects with hemiparesis adopt

Tropical rainfall trend and stationarity analysis
, 2020 Climate change is most likely to cause changes to the temporal and spatial variability of rainfall. A trend analysis to investigate the rainfall pattern can detect changes over temporal and spatial scales for a rainfall series.

Graph Variogram: A novel tool to measure spatial stationarity
, 2018 Irregularly sampling a spatially stationary random field does not yield a graph stationary signal in general. Based on this observation, we build a definition of graph stationarity based on intrinsic stationarity, a less restrictive definition of ...

Advanced Energy Materials, EarlyView.The origin of variations in solid‐state battery cell performance is explored and traced back mainly to the cathode composite mixing – leading to different fractions of electrochemically active mass. Machine‐mixed composites and the quantification of the electrochemically active mass enhance reproducibility and comparability.
