Spatial wildfire risk modeling using mixtures of tree-based multivariate Pareto distributions

Authors: Daniela Cisneros, Arnab Hazra, Raphaël Huser

arXiv

Wildfires pose a severe threat to the ecosystem and economy, and risk assessment is typically based on fire danger indices such as the McArthur Forest Fire Danger Index (FFDI) used in Australia. Study...

A hierarchical Bayesian model for estimating age-specific COVID-19 infection fatality rates in developing countries

Authors: Sierra Pugh, Andrew T. Levin, Gideon Meyerowitz-Katz, Satej Soman, Nana Owusu-Boaitey, Anthony B. Zwi, Anup Malani, Ander Wilson, Bailey K. Fosdick

arXiv

The COVID-19 infection fatality rate (IFR) is the proportion of individuals infected with SARS-CoV-2 who subsequently die. As COVID-19 disproportionately affects older individuals, age-specific IFR es...

Applicability of scaling laws to vision encoding models

Authors: Takuya Matsuyama, Kota S Sasaki, Shinji Nishimoto

arXiv

In this paper, we investigated how to build a high-performance vision encoding model to predict brain activity as part of our participation in the Algonauts Project 2023 Challenge. The challenge provi...

Estimating Mean Viral Load Trajectory from Intermittent Longitudinal Data and Unknown Time Origins

Authors: Yonatan Woodbridge, Micha Mandel, Yair Goldberg, Amit Huppert

arXiv

Viral load (VL) in the respiratory tract is the leading proxy for assessing infectiousness potential. Understanding the dynamics of disease-related VL within the host is very important and help to det...

Modeling Random Networks with Heterogeneous Reciprocity

Authors: Daniel Cirkovic, Tiandong Wang

arXiv

Reciprocity, or the tendency of individuals to mirror behavior, is a key measure that describes information exchange in a social network. Users in social networks tend to engage in different levels of...

Oscillatory networks: Insights from piecewise-linear modeling

Authors: Stephen Coombes, Mustafa Sayli, Rüdiger Thul, Rachel Nicks, Mason A Porter, Yi Ming Lai

arXiv

There is enormous interest -- both mathematically and in diverse applications -- in understanding the dynamics of coupled oscillator networks. The real-world motivation of such networks arises from st...

California Exodus? A Network Model of Population Redistribution in the United States

Authors: Peng Huang, Carter T. Butts

arXiv

Motivated by debates about California's net migration loss, we employ valued exponential-family random graph models to analyze the inter-county migration flow networks in the United States. We introdu...

A One-Parameter Diagnostic Classification Model with Familiar Measurement Properties

Authors: Matthew J. Madison, Stefanie A Wind, Lientje Maas, Kazuhiro Yamaguchi, Sergio Haab

arXiv

Diagnostic classification models (DCMs) are psychometric models designed to classify examinees according to their proficiency or non-proficiency of specified latent characteristics. These models are w...

The minimal computational substrate of fluid intelligence

Authors: Amy PK Nelson, Joe Mole, Guilherme Pombo, Robert J Gray, James K Ruffle, Edgar Chan, Geraint E Rees, Lisa Cipolotti, Parashkev Nachev

arXiv

The quantification of cognitive powers rests on identifying a behavioural task that depends on them. Such dependence cannot be assured, for the powers a task invokes cannot be experimentally controlle...

Meta predictive learning model of languages in neural circuits

Authors: Chan Li, Junbin Qiu, Haiping Huang

arXiv

Large language models based on self-attention mechanisms have achieved astonishing performances not only in natural language itself, but also in a variety of tasks of different nature. However, regard...

QIENet: Quantitative irradiance estimation network using recurrent neural network based on satellite remote sensing data

Authors: Longfeng Nie, Yuntian Chen, Dongxiao Zhang, Xinyue Liu, Wentian Yuan

arXiv

Global horizontal irradiance (GHI) plays a vital role in estimating solar energy resources, which are used to generate sustainable green energy. In order to estimate GHI with high spatial resolution,...

Streaming Bayesian Modeling for predicting Fat-Tailed Customer Lifetime Value

Authors: Alexey V. Calabourdin, Konstantin A. Aksenov

arXiv

We develop an online learning MCMC approach applicable for hierarchical bayesian models and GLMS. We also develop a fat-tailed LTV model that generalizes over several kinds of fat and thin tails. We d...
