Stochastic firing rate models

Authors: Jonathan Touboul, Bard Ermentrout, Olivier Faugeras, Bruno Cessac

arXiv

We review a recent approach to the mean-field limits in neural networks that takes into account the stochastic nature of input current and the uncertainty in synaptic coupling. This approach was pro...

Robust and Trend-following Kalman Smoothers using Student's t

Authors: Aleksandr Y. Aravkin, James V. Burke, Gianluigi Pillonetto

arXiv

We propose two nonlinear Kalman smoothers that rely on Student's t distributions. The T-Robust smoother finds the maximum a posteriori likelihood (MAP) solution for Gaussian process noise and Student'...

Prediction

Authors: Didier Sornette, Ivan Osorio

arXiv

This chapter first presents a rather personal view of some different aspects of predictability, going in crescendo from simple linear systems to high-dimensional nonlinear systems with stochastic forc...

Illusions in the Ring Model of visual orientation selectivity

Authors: Romain Veltz, Olivier Faugeras

arXiv

The Ring Model of orientation tuning is a dynamical model of a hypercolumn of visual area V1 in the human neocortex that has been designed to account for the experimentally observed orientation tuning...

The Ising decoder: reading out the activity of large neural ensembles

Authors: Michael T. Schaub, Simon R. Schultz

arXiv

The Ising Model has recently received much attention for the statistical description of neural spike train data. In this paper, we propose and demonstrate its use for building decoders capable of pred...

Bayesian matching of unlabelled point sets using Procrustes and configuration models

Authors: Kim Kenobi, Ian L. Dryden

arXiv

The problem of matching unlabelled point sets using Bayesian inference is considered. Two recently proposed models for the likelihood are compared, based on the Procrustes size-and-shape and the full...

Bayesian Gene Set Analysis

Authors: Babak Shahbaba, Robert Tibshirani, Catherine M. Shachaf, Sylvia K. Plevritis

arXiv

Gene expression microarray technologies provide the simultaneous measurements of a large number of genes. Typical analyses of such data focus on the individual genes, but recent work has demonstrated...

Uncertainty of visual measurement and efficient allocation of sensory resources

Authors: Sergei Gepshtein, Ivan Tyukin

arXiv

We review the reasoning underlying two approaches to combination of sensory uncertainties. First approach is noncommittal, making no assumptions about properties of uncertainty or parameters of stimul...

Using epidemic prevalence data to jointly estimate reproduction and removal

Authors: Jan van den Broek, Hiroshi Nishiura

arXiv

This study proposes a nonhomogeneous birth--death model which captures the dynamics of a directly transmitted infectious disease. Our model accounts for an important aspect of observed epidemic data i...

Truck-Involved Crashes Injury Severity Analysis for Different Lighting Conditions on Rural and Urban Roadways

Authors: Majbah Uddin, Nathan Huynh

arXiv

This paper investigates factors affecting injury severity of crashes involving trucks for different lighting conditions on rural and urban roadways. It uses 2009-2013 Ohio crash data from the Highway...

Factors Influencing Mode Choice of Adults with Travel-Limiting Disability

Authors: Majbah Uddin, Meiyu, Pan, Ho-Ling Hwang

arXiv

Despite the plethora of research devoted to analyzing the impact of disability on travel behavior, not enough studies have investigated the varying impact of social and environmental factors on the mo...

Equipment Health Assessment: Time Series Analysis for Wind Turbine Performance

Authors: Jana Backhus, Aniruddha Rajendra Rao, Chandrasekar Venkatraman, Abhishek Padmanabhan, A. Vinoth Kumar, Chetan Gupta

arXiv

In this study, we leverage SCADA data from diverse wind turbines to predict power output, employing advanced time series methods, specifically Functional Neural Networks (FNN) and Long Short-Term Memo...

Thematic agreement assessment of gridded, multi-modal geospatial datasets of different semantics and spatial granularities

Authors: Johannes H. Uhl, Stefan Leyk

arXiv

This paper presents a method for thematic agreement assessment of geospatial data products of different semantics and spatial granularities, which may be affected by spatial offsets between test and r...

Efficient statistical analysis of large correlated multivariate datasets: a case study on brain connectivity matrices

Authors: Djalel Eddine Meskaldji, Leila Cammoun, Patric Hagmann, Reto Meuli, Jean Philippe Thiran, Stephan Morgenthaler

arXiv

In neuroimaging, a large number of correlated tests are routinely performed to detect active voxels in single-subject experiments or to detect regions that differ between individuals belonging to diff...
