A new latent cure rate marker model for survival data

Authors: Sungduk Kim, Yingmei Xi, Ming-Hui Chen

arXiv

To address an important risk classification issue that arises in clinical practice, we propose a new mixture model via latent cure rate markers for survival data with a cure fraction. In the propose...

Neural Network Based Parameter Estimation Method for the Pareto/NBD Model

Authors: Shao-Ming Xie

arXiv

Whether stochastic or parametric, the Pareto/NBD model can only be utilized for an in-sample prediction rather than an out-of-sample prediction. This research thus provides a neural network based exte...

Towards an information theoretical description of communication in brain networks

Authors: Enrico Amico, Kausar Abbas, Duy Anh Duong-Tran, Uttara Tipnis, Meenusree Rajapandian, Evgeny Chumin, Mario Ventresca, Jaroslaw Harezlak, Joaquƭn GoƱi

arXiv

Modeling communication dynamics in the brain is a key challenge in network neuroscience. We present here a framework that combines two measurements for any system where different communication process...

Modeling Material Stress Using Integrated Gaussian Markov Random Fields

Authors: Peter W. Marcy, Scott A. Vander Wiel, Curtis B. Storlie, Veronica Livescu, Curt A. Bronkhorst

arXiv

The equations of a physical constitutive model for material stress within tantalum grains were solved numerically using a tetrahedrally meshed volume. The resulting output included a scalar vonMises s...

The Comparison of Methods for Individual Treatment Effect Detection

Authors: Aleksey Buzmakov, Daria Semenova, Maria Temirkaeva

arXiv

Today, treatment effect estimation at the individual level is a vital problem in many areas of science and business. For example, in marketing, estimates of the treatment effect are used to select the...

Space-Time Landslide Predictive Modelling

Authors: Luigi Lombardo, Thomas Opitz, Francesca Ardizzone, Fausto Guzzetti, Raphaƫl Huser

arXiv

Landslides are nearly ubiquitous phenomena and pose severe threats to people, properties, and the environment. Investigators have for long attempted to estimate landslide hazard to determine where, wh...

Extracting Trips from Multi-Sourced Data for Mobility Pattern Analysis: An App-Based Data Example

Authors: Feilong Wang, Jingxing Wang, Jinzhou Cao, Cynthia Chen, Xuegang, Ban

arXiv

Passively-generated data, such as GPS data and cellular data, bring tremendous opportunities for human mobility analysis and transportation applications. Since their primary purposes are often non-tra...

A regularized hidden Markov model for analyzing the 'hot shoe' in football

Authors: Marius Ɩtting, Andreas Groll

arXiv

Although academic research on the 'hot hand' effect (in particular, in sports, especially in basketball) has been going on for more than 30 years, it still remains a central question in different area...

Neocortical plasticity: an unsupervised cake but no free lunch

Authors: Eilif B. Muller, Philippe Beaudoin

arXiv

The fields of artificial intelligence and neuroscience have a long history of fertile bi-directional interactions. On the one hand, important inspiration for the development of artificial intelligence...

Estimating high-resolution Red Sea surface temperature hotspots, using a low-rank semiparametric spatial model

Authors: Arnab Hazra, Raphaƫl Huser

arXiv

In this work, we estimate extreme sea surface temperature (SST) hotspots, i.e., high threshold exceedance regions, for the Red Sea, a vital region of high biodiversity. We analyze high-resolution sate...

Correlated Effects of Relative Size and Depth in the Perceptual Organization of Multiple Figure-Ground Configurations

Authors: Birgitta Dresp-Langley, Adam Reeves

arXiv

The neural networks of the human visual brain derive representations of three-dimensional structure from specific two-dimensional image cues. Neural models backed by psychophysical data predict how lo...

Control of excitable systems is optimal near criticality

Authors: Kathleen Finlinson, Woodrow L. Shew, Daniel B. Larremore, Juan G. Restrepo

arXiv

Experiments suggest that cerebral cortex gains several functional advantages by operating in a dynamical regime near the critical point of a phase transition. However, a long-standing criticism of thi...

A crossover code for high-dimensional composition

Authors: Rich Pang

arXiv

We present a novel way to encode compositional information in high-dimensional (HD) vectors. Inspired by chromosomal crossover, random HD vectors are recursively interwoven, with a fraction of one vec...

Improved algorithm for neuronal ensemble inference by Monte Carlo method

Authors: Shun Kimura, Koujin Takeda

arXiv

Neuronal ensemble inference is one of the significant problems in the study of biological neural networks. Various methods have been proposed for ensemble inference from their activity data taken expe...

Semiparametric Estimation of Correlated Random Coefficient Models without Instrumental Variables

Authors: Samuele Centorrino, Aman Ullah, Jing Xue

arXiv

We study a linear random coefficient model where slope parameters may be correlated with some continuous covariates. Such a model specification may occur in empirical research, for instance, when quan...
