Minimal model of associative learning for cross-situational lexicon acquisition

Authors: Paulo F. C. Tilles, Jose F. Fontanari

arXiv

An explanation for the acquisition of word-object mappings is the associative learning in a cross-situational scenario. Here we present analytical results of the performance of a simple associative le...

Which coordinate system for modelling path integration?

Authors: Robert J. Vickerstaff, Allen Cheung

arXiv

Path integration is a navigation strategy widely observed in nature where an animal maintains a running estimate of its location during an excursion. Evidence suggests it is both ancient and ubiquitou...

The span of correlations in dolphin whistle sequences

Authors: Ramon Ferrer-i-Cancho, Brenda McCowan

arXiv

Long-range correlations are found in symbolic sequences from human language, music and DNA. Determining the span of correlations in dolphin whistle sequences is crucial for shedding light on their com...

Maxent in Experimental 2$\times$2 Population Games

Authors: Bin Xu, Zhijian Wang

arXiv

In mixed strategy 2\times2 population games, the realization of maximum entropy (Maxent) is of the theoretical expectation. We evaluate this theoretical prediction in the experimental economics game d...

Description of the EMOD-HIV Model v0.7

Authors: Anna Bershteyn, Daniel J. Klein, Edward Wenger, Philip A. Eckhoff

arXiv

The expansion of tools against HIV transmission has brought increased interest in epidemiological models that can predict the impact of these interventions. The EMOD-HIV model was recently compared to...

Futures pricing in electricity markets based on stable CARMA spot models

Authors: Fred Espen Benth, Claudia Klüppelberg, Gernot Müller, Linda Vos

arXiv

We present a new model for the electricity spot price dynamics, which is able to capture seasonality, low-frequency dynamics and the extreme spikes in the market. Instead of the usual purely determini...

Maximally informative "stimulus energies" in the analysis of neural responses to natural signals

Authors: Kanaka Rajan, William Bialek

arXiv

The concept of feature selectivity in sensory signal processing can be formalized as dimensionality reduction: in a stimulus space of very high dimensions, neurons respond only to variations within so...

Marginal analysis of longitudinal count data in long sequences: Methods and applications to a driving study

Authors: Zhiwei Zhang, Paul S. Albert, Bruce Simons-Morton

arXiv

Most of the available methods for longitudinal data analysis are designed and validated for the situation where the number of subjects is large and the number of observations per subject is relatively...

An exact adaptive test with superior design sensitivity in an observational study of treatments for ovarian cancer

Authors: Paul R. Rosenbaum

arXiv

A sensitivity analysis in an observational study determines the magnitude of bias from nonrandom treatment assignment that would need to be present to alter the qualitative conclusions of a naïve anal...

Fast estimation of posterior probabilities in change-point models through a constrained hidden Markov model

Authors: The-Minh Luong, Yves Rozenholc, Gregory Nuel

arXiv

The detection of change-points in heterogeneous sequences is a statistical challenge with applications across a wide variety of fields. In bioinformatics, a vast amount of methodology exists to identi...

Gender differences in time perception and its relation with academic performance: non-linear dynamics in the formation of cognitive systems

Authors: Klaus Jaffe, Guillermo Mascitti, Daniella Seguias

arXiv

Non-linear dynamics is probably much more common in the epigenetic dynamics of living beings than hitherto recognized. Here we report a case of global bifurcation triggered by gender that affects high...

Authors: Hedibert F. Lopes, Alexandra M. Schmidt, Esther Salazar, Mariana Gómez, Marcel Achkar

arXiv

We propose a model-based vulnerability index of the population from Uruguay to vector-borne diseases. We have available measurements of a set of variables in the census tract level of the 19 Departmen...

A Note On the Use of Fiducial Limits for Control Charts

Authors: Mokin Lee, Chanseok Park

arXiv

Many of the early works in the quality control literature construct control limits through the use of graphs and tables as described in Wortham and Ringer (1972). However, the methods used in this lit...
