Estimation and uncertainty quantification for the output from quantum simulators

Authors: Ryan Bennink, Ajay Jasra, Kody J. H. Law, Pavel Lougovski

arXiv

The problem of estimating certain distributions over $\{0,1\}^d$ is considered here. The distribution represents a quantum system of $d$ qubits, where there are non-trivial dependencies between the qu...

A novel quantum theory of psychology

Authors: Jiao-Kai Chen

arXiv

The behavior coordinate system and the ideal individual model are presented. The behavior state of an ideal individual is assumed to be represented by a behavior state function. Based on the ideal ind...

Learning spatially-correlated temporal dictionaries for calcium imaging

Authors: Gal Mishne, Adam S. Charles

arXiv

Calcium imaging has become a fundamental neural imaging technique, aiming to recover the individual activity of hundreds of neurons in a cortical region. Current methods (mostly matrix factorization)...

Hawkes processes for credit indices time series analysis: How random are trades arrival times?

Authors: Achraf Bahamou, Maud Doumergue, Philippe Donnat

arXiv

Targeting a better understanding of credit market dynamics, the authors have studied a stochastic model named the Hawkes process. Describing trades arrival times, this kind of model allows for the cap...

Bayesian semi-parametric G-computation for causal inference in a cohort study with MNAR dropout and death

Authors: Maria Josefsson, Michael J. Daniels

arXiv

Causal inference with observational longitudinal data and time-varying exposures is often complicated by time-dependent confounding and attrition. The G-computation formula is one approach for estimat...
