Evaluating District-based Election Surveys with Synthetic Dirichlet Likelihood

Authors: Adway Mitra, Palash Dey

arXiv

In district-based multi-party elections, electors cast votes in their respective districts. In each district, the party with maximum votes wins the corresponding seat in the governing body. Election S...

Movement of insurgent gangs: A Bayesian kernel density model for incomplete temporal data

Authors: Karthik Sriram, Dhruv Gupta, Rajiv Parikh

arXiv

We develop a Bayesian modeling framework to address a pressing real-life problem faced by the police in tackling insurgent gangs. Unlike criminals associated with common crimes such as robbery, theft...

Multi-Modal Cognitive Maps based on Neural Networks trained on Successor Representations

Authors: Paul Stoewer, Achim Schilling, Andreas Maier, Patrick Krauss

arXiv

Cognitive maps are a proposed concept on how the brain efficiently organizes memories and retrieves context out of them. The entorhinal-hippocampal complex is heavily involved in episodic and relation...

Urban Street Network Design and Transport-Related Greenhouse Gas Emissions around the World

Authors: Geoff Boeing, Clemens Pilgram, Yougeng Lu

arXiv

This study estimates the relationships between street network characteristics and transport-sector CO2 emissions across every urban area in the world and investigates whether they are the same across...

Robust learning of staged tree models: A case study in evaluating transport services

Authors: Manuele Leonelli, Gherardo Varando

arXiv

Staged trees are a relatively recent class of probabilistic graphical models that extend Bayesian networks to formally and graphically account for non-symmetric patterns of dependence. Machine learnin...

A spatial mixture model for spaceborne lidar observations over mixed forest and non-forest land types

Authors: Paul B. May, Andrew O. Finley, Ralph O. Dubayah

arXiv

The Global Ecosystem Dynamics Investigation (GEDI) is a spaceborne lidar instrument that collects near-global measurements of forest structure. While expansive in scope, GEDI samples are spatially spa...

Improved estimators in Bell regression model with application

Authors: Solmaz Seifollahi, Hossein Bevrani, Zakariya Yahya Algamal

arXiv

In this paper, we propose the application of shrinkage strategies to estimate coefficients in the Bell regression models when prior information about the coefficients is available. The Bell regression...

Assessing Time Series Correlation Significance: A Parametric Approach with Application to Physiological Signals

Authors: Johan Medrano, Abderrahmane Kheddar, Sofiane Ramdani

arXiv

Correlation coefficients play a pivotal role in quantifying linear relationships between random variables. Yet, their application to time series data is very challenging due to temporal dependencies....

A network-level transport model of tau progression in the Alzheimer's brain

Authors: Veronica Tora, Justin Torok, Michiel Bertsch, Ashish Raj

arXiv

One of the hallmarks of Alzheimer's disease (AD) is the accumulation and spread of toxic aggregates of tau protein. The progression of AD tau pathology is thought to be highly stereotyped, which is in...

ceylon: An R package for plotting the maps of Sri Lanka

Authors: Thiyanga S. Talagala

arXiv

The rapid evolution in the fields of computer science, data science, and artificial intelligence has significantly transformed the utilisation of data for decision-making. Data visualisation plays a c...

Learning Causal Representations from General Environments: Identifiability and Intrinsic Ambiguity

Authors: Jikai Jin, Vasilis Syrgkanis

arXiv

We study causal representation learning, the task of recovering high-level latent variables and their causal relationships in the form of a causal graph from low-level observed data (such as text and...

Bayesian Cluster Geographically Weighted Regression for Spatial Heterogeneous Data

Authors: Wala Draidi Areed, Aiden Price, Helen Thompson, Conor Hassan, Reid Malseed, Kerrie Mengersen

arXiv

Spatial statistical models are commonly used in geographical scenarios to ensure spatial variation is captured effectively. However, spatial models and cluster algorithms can be complicated and expens...

Differential action of TIGIT on islet and peripheral nerve autoimmunity in the NOD mouse

Authors: Chantal Bécourt, Sandrine Luce, Ute C Rogner, Christian Boitard

arXiv

We previously demonstrated that the abrogation of the ICOS pathway prevents type 1 diabetes development in the Non Obese Diabetic (NOD) mouse, but results in a CD4+ T-cell dependent autoimmune neuromy...

How does the elimination of group mean-differences affect factor score determinacy?

Authors: André Beauducel, Norbert Hilger

arXiv

The present study investigates to what degree the common variance of the factor score predictor with the original factor, i.e., the determinacy coefficient or the validity of the factor score predicto...

Fusing Climate Data Products using a Spatially Varying Autoencoder

Authors: Jacob A. Johnson, Matthew J. Heaton, William F. Christensen, Lynsie R. Warr, Summer B. Rupper

arXiv

Autoencoders are powerful machine learning models used to compress information from multiple data sources. However, autoencoders, like all artificial neural networks, are often unidentifiable and unin...
