Why approximate Bayesian computational (ABC) methods cannot handle model choice problems

Authors: Christian Robert, Jean-Michel Marin, Natesh S. Pillai

arXiv

Approximate Bayesian computation (ABC), also known as likelihood-free methods, have become a favourite tool for the analysis of complex stochastic models, primarily in population genetics but also in...

Analysis of a capture-recapture estimator for the size of populations with heterogenous catchability, and its evaluation on RDS data from rural Uganda

Authors: Yakir Berchenko, Richard G. White, Cyprian Wejnert, Simon D. W. Frost

arXiv

In this paper, we consider capture-recapture experiments with heterogenous catchability. In the setting we consider, the widespread Huggins-Alho estimator is not very suitable and we introduce and stu...

Mesoscopic approach to minority games in herd regime

Authors: Karol Wawrzyniak, Wojciech Wislicki

arXiv

We study minority games in efficient regime. By incorporating the utility function and aggregating agents with similar strategies we develop an effective mesoscale notion of state of the game. Using t...

Target Detection Performance Bounds in Compressive Imaging

Authors: Kalyani Krishnamurthy, Rebecca Willett, Maxim Raginsky

arXiv

This paper describes computationally efficient approaches and associated theoretical performance guarantees for the detection of known targets and anomalies from few projection measurements of the und...

Evolution and development of Brain Networks: From Caenorhabditis elegans to Homo sapiens

Authors: Marcus Kaiser, Sreedevi Varier

arXiv

Neural networks show a progressive increase in complexity during the time course of evolution. From diffuse nerve nets in Cnidaria to modular, hierarchical systems in macaque and humans, there is a gr...

Reliability-based design optimization of imperfect shells using adaptive kriging meta-models

Authors: Vincent Dubourg, Jean-Marc Bourinet, Bruno Sudret

arXiv

The optimal and robust design of structures has gained much attention in the past ten years due to the ever increasing need for manufacturers to build robust systems at the lowest cost. Reliability-ba...

Vertex Nomination via Content and Context

Authors: Glen A. Coppersmith, Carey E. Priebe

arXiv

If I know of a few persons of interest, how can a combination of human language technology and graph theory help me find other people similarly interesting? If I know of a few people committing a crim...

On Reverse Engineering in the Cognitive and Brain Sciences

Authors: Andreas Schierwagen

arXiv

Various research initiatives try to utilize the operational principles of organisms and brains to develop alternative, biologically inspired computing paradigms and artificial cognitive systems. This...

Effect of synaptic plasticity in the structure and dynamics of disordered networks of coupled neurons

Authors: Mehdi Bayati, Alireza Valizadeh

arXiv

In an all-to-all network of integrate-fire oscillators in which there is a disorder in the intrinsic firing rates of the neurons, we show that through spike timing-dependent plasticity the links which...

Capturing the time-varying drivers of an epidemic using stochastic dynamical systems

Authors: Joseph Dureau, Konstantinos Kalogeropoulos, Marc Baguelin

arXiv

Epidemics are often modelled using non-linear dynamical systems observed through partial and noisy data. In this paper, we consider stochastic extensions in order to capture unknown influences (changi...

Forecast verification for extreme value distributions with an application to probabilistic peak wind prediction

Authors: Petra Friederichs, Thordis L. Thorarinsdottir

arXiv

Predictions of the uncertainty associated with extreme events are a vital component of any prediction system for such events. Consequently, the prediction system ought to be probabilistic in nature, w...

Estimating the age of renal tumors

Authors: Allen B. Downey

arXiv

We present a Bayesian method for estimating the age of a renal tumor given its size. We use a model of tumor growth based on published data from observations of untreated tumors. We find, for example,...

Signal integration enhances the dynamic range in neuronal systems

Authors: Leonardo L. Gollo, Claudio Mirasso, Víctor M. Eguíluz

arXiv

The dynamic range measures the capacity of a system to discriminate the intensity of an external stimulus. Such an ability is fundamental for living beings to survive: to leverage resources and to avo...

TRPC4 ion channel protein is selectively expressed in a subpopulation of dopamine neurons in the ventral tegmental area

Authors: Kurt R. Illig, Kristin C. Rasmus, Andrew L. Varnell, Eric M. Ostertag, William D. Klipec, Donald C. Cooper

arXiv

The nonselective cation channel TRPC4 has been shown to be present in high abundance in the corticolimbic regions of the brain and play a pivotal role in modulating cellular excitability due to their...

A Reanalysis of North Pacific Sea Surface Temperatures Using State-Space Techniques: The PDO In A New Light

Authors: Roy Mendelssohn, CIndy Bessey

arXiv

North Pacific sea surface temperatures (SST), as used in estimating the PDO, are reanalyzed using state-space decomposition and subspace identification techniques. The reanalysis presents a very diffe...
