A D-vine copula mixed model for joint meta-analysis and comparison of diagnostic tests

Authors: Aristidis K. Nikoloulopoulos

arXiv

For a particular disease there may be two diagnostic tests developed, where each of the tests is subject to several studies. A quadrivariate generalized linear mixed model (GLMM) has been recently pro...

Trans-Gaussian Kriging in a Bayesian framework : a case study

Authors: Joseph Muré

arXiv

In the context of Gaussian Process Regression or Kriging, we propose a full-Bayesian solution to deal with hyperparameters of the covariance function. This solution can be extended to the Trans-Gaussi...

Penalized polytomous ordinal logistic regression using cumulative logits. Application to network inference of zero-inflated variables

Authors: Aurélie Deveau, Anne Gégout-Petit, Clémence Karmann

arXiv

We consider the problem of variable selection when the response is ordinal, that is an ordered categorical variable. In particular, we are interested in selecting quantitative explanatory variables li...

Optimal stimulation protocol in a bistable synaptic consolidation model

Authors: Chiara Gastaldi, Samuel P. Muscinelli, Wulfram Gerstner

arXiv

Consolidation of synaptic changes in response to neural activity is thought to be fundamental for memory maintenance over a timescale of hours. In experiments, synaptic consolidation can be induced by...

A neural network trained to predict future video frames mimics critical properties of biological neuronal responses and perception

Authors: William Lotter, Gabriel Kreiman, David Cox

arXiv

While deep neural networks take loose inspiration from neuroscience, it is an open question how seriously to take the analogies between artificial deep networks and biological neuronal systems. Intere...

Using spike train distances to identify the most discriminative neuronal subpopulation

Authors: Eero Satuvuori, Mario Mulansky, Andreas Daffertshofer, Thomas Kreuz

arXiv

Background: Spike trains of multiple neurons can be analyzed following the summed population (SP) or the labeled line (LL) hypothesis. Responses to external stimuli are generated by a neuronal populat...

Data-driven Perception of Neuron Point Process with Unknown Unknowns

Authors: Ruochen Yang, Gaurav Gupta, Paul Bogdan

arXiv

Identification of patterns from discrete data time-series for statistical inference, threat detection, social opinion dynamics, brain activity prediction has received recent momentum. In addition to t...

WheelCon: A wheel control-based gaming platform for studying human sensorimotor control

Authors: Quanying Liu, Yorie Nakahira, Ahkeel Mohideen, Adam Dai, Sunghoon Choi, Angelina Pan, Dimitar M. Ho, John C. Doyle

arXiv

Feedback control theory has been extensively implemented to theoretically model human sensorimotor control. However, experimental platforms capable of manipulating important components of multiple fee...

A spatially resolved network spike in model neuronal cultures reveals nucleation centers, circular traveling waves and drifting spiral waves

Authors: A. V. Paraskevov, D. K. Zendrikov

arXiv

We show that in model neuronal cultures, where the probability of interneuronal connection formation decreases exponentially with increasing distance between the neurons, there exists a small number o...

Labeling Bias in Galaxy Morphologies

Authors: Guillermo Cabrera-Vives, Christopher J. Miller, Jeff Schneider

arXiv

We present a metric to quantify systematic labeling bias in galaxy morphology data sets stemming from the quality of the labeled data. This labeling bias is independent from labeling errors and requir...

Assessing the Contribution of Semantic Congruency to Multisensory Integration and Conflict Resolution

Authors: Di Fu, Pablo Barros, German I. Parisi, Haiyan Wu, Sven Magg, Xun Liu, Stefan Wermter

arXiv

The efficient integration of multisensory observations is a key property of the brain that yields the robust interaction with the environment. However, artificial multisensory perception remains an op...

Learning differentially reorganizes brain activity and connectivity

Authors: Maxwell A Bertolero, Azeez Adebimpe, Ankit N. Khambhati, Marcelo G. Mattar, Daniel Romer, Sharon L. Thompson-Schill, Danielle S. Bassett

arXiv

Human learning is a complex process in which future behavior is altered via the reorganization of brain activity and connectivity. It remains unknown whether activity and connectivity differentially r...

Suppression and facilitation of motion perception in humans: a reply to Schallmo & Murray (2018)

Authors: Tzvetomir Tzvetanov

arXiv

In a recent publication (Tzvetanov (2018), bioRxiv 465807), I made an extensive analysis with computational modelling and psychophysics of the simple experimental design of Dr. D.Tadin (Tadin, Lappin,...

Similarity-based Random Survival Forest

Authors: Yingying Xu, Joon Lee, Joel A. Dubin

arXiv

Predicting time-to-event outcomes in large databases can be a challenging but important task. One example of this is in predicting the time to a clinical outcome for patients in intensive care units (...

An Algorithmic Approach to Forecasting Rare Violent Events: An Illustration Based in IPV Perpetration

Authors: Richard A. Berk, Susan B. Sorenson

arXiv

Mass violence, almost no matter how defined, is (thankfully) rare. Rare events are very difficult to study in a systematic manner. Standard statistical procedures can fail badly and usefully accurate...
