Utility and Disclosure Risk for Differentially Private Synthetic Categorical Data

Authors: Gillian M Raab

arXiv

This paper introduces two methods of creating differentially private (DP) synthetic data that are now incorporated into the \textit{synthpop} package for \textbf{R}. Both are suitable for synthesising...

Probabilistic forecasting of bus travel time with a Bayesian Gaussian mixture model

Authors: Xiaoxu Chen, Zhanhong Cheng, Jian Gang Jin, Martin Trepanier, Lijun Sun

arXiv

Accurate forecasting of bus travel time and its uncertainty is critical to service quality and operation of transit systems; for example, it can help passengers make better decisions on departure time...

Classification of EEG Motor Imagery Using Deep Learning for Brain-Computer Interface Systems

Authors: Alessandro Gallo, Manh Duong Phung

arXiv

A trained T1 class Convolutional Neural Network (CNN) model will be used to examine its ability to successfully identify motor imagery when fed pre-processed electroencephalography (EEG) data. In theo...

A solution for the rare type match problem when using the DIP-STR marker system

Authors: Giulia Cereda, Richard D. Gill, Franco Taroni

arXiv

The rare type match problem is an evaluative challenging situation in which the analysis of a DNA profile reveals the presence of (at least) one allele which is not contained in the reference database...

Two-Sided EWMA Charts for Monitoring Double Bounded Processes

Authors: Argyro Lafatzi, Athanasios Rakitzis

arXiv

In this work, we study the performance of two-sided EWMA charts for monitoring double bounded processes using individual observations. Specifically, the term double bounded refers to observations in t...

Comparison between an exact and a heuristic neural mass model with second order synapses

Authors: Pau Clusella, Elif Köksal-Ersöz, Jordi Garcia-Ojalvo, Giulio Ruffini

arXiv

Neural mass models (NMMs) are designed to reproduce the collective dynamics of neuronal populations. A common framework for NMMs assumes heuristically that the output firing rate of a neural populatio...

Assessing Machine Learning Algorithms for Near-Real Time Bus Ridership Prediction During Extreme Weather

Authors: Francisco Rowe, Michael Mahony, Sui Tao

arXiv

Given an increasingly volatile climate, the relationship between weather and transit ridership has drawn increasing interest. However, challenges stemming from spatio-temporal dependency and non-stati...

Interpretability of Machine Learning Methods Applied to Neuroimaging

Authors: Elina Thibeau-Sutre, Sasha Collin, Ninon Burgos, Olivier Colliot

arXiv

Deep learning methods have become very popular for the processing of natural images, and were then successfully adapted to the neuroimaging field. As these methods are non-transparent, interpretabilit...

Bayesian estimation of in-game home team win probability for college basketball

Authors: Jason Maddox, Ryan Sides, Jane Harvill

arXiv

Two new Bayesian methods for estimating and predicting in-game home team win probabilities are proposed. The first method has a prior that adjusts as a function of lead differential and time elapsed....

An Efficient Dynamic Sampling Policy For Monte Carlo Tree Search

Authors: Gongbo Zhang, Yijie Peng, Yilong Xu

arXiv

We consider the popular tree-based search strategy within the framework of reinforcement learning, the Monte Carlo Tree Search (MCTS), in the context of finite-horizon Markov decision process. We prop...

Outcome coding choice in randomized trials of programs to reduce violence

Authors: Christopher Boyer, Sangeeta Chatterji, Jasper Cooper, Lori Heise

arXiv

Over the last decade, the number of randomized trials of programs to reduce intimate partner violence (IPV) has grown precipitously. However, most trials continue to measure and code violence using st...

Joint Study of Above Ground Biomass and Soil Organic Carbon for Total Carbon Estimation using Satellite Imagery in Scotland

Authors: Terrence Chan, Carla Arus Gomez, Anish Kothikar, Pedro Baiz

arXiv

Land Carbon verification has long been a challenge in the carbon credit market. Carbon verification methods currently available are expensive, and may generate low-quality credit. Scalable and accurat...
