A review on data fusion in multimodal learning analytics and educational data mining
Wilson Chango, Juan A. Lara, Rebeca Cerezo +1
The new educational models such as smart learning environments use of digital and context-aware devices to facilitate the learning process. In this new educational scenario, a huge…
Improving prediction of students' performance in intelligent tutoring systems using attribute selection and ensembles of different multimodal data sources
W. Chango, R. Cerezo, M. Sanchez-Santillan +2
The aim of this study was to predict university students' learning performance using different sources of data from an Intelligent Tutoring System. We collected and preprocessed da…
Multi-source and multimodal data fusion for predicting academic performance in blended learning university courses
W. Chango, R. Cerezo, C. Romero
In this paper we applied data fusion approaches for predicting the final academic performance of university students using multiple-source, multimodal data from blended learning en…
Artificial Pupil Dilation for Data Augmentation in Iris Semantic Segmentation
Daniel P. Benalcazar, David A. Benalcazar, Andres Valenzuela
Biometrics is the science of identifying an individual based on their intrinsic anatomical or behavioural characteristics, such as fingerprints, face, iris, gait, and voice. Iris r…
Some properties related to the Cantor-Bendixson derivative on a Polish space
Borys Álvarez-Samaniego, Andrés Merino
We show a necessary and sufficient condition for any ordinal number to be a Polish space. We also prove that for each countable Polish space, there exists a countable ordinal numbe…
Presence-absence estimation in audio recordings of tropical frog communities
Andrés Estrella Terneux, Damián Nicolalde, Daniel Nicolalde +1
One non-invasive way to study frog communities is by analyzing long-term samples of acoustic material containing calls. This immense task has been optimized by the development of M…
A Reactive-Darwinian Model for the Ultimatum Game: On the Dominance of Moderation in High Diffusion
Roberto da Silva, Pablo Valverde, Luis C. Lamb
We consider a version of the ultimatum game which simultaneously combines reactive and Darwinian aspects with offers in [0,1]. By reactive aspects, we consider the effects that lea…
On the Star Formation Properties of Void Galaxies
Crystal M. Moorman, Jackeline Moreno, Amanda White +4
We measure the star formation properties of two large samples of galaxies from the SDSS in large-scale cosmic voids on time scales of 10 Myr and 100 Myr, using H emission line s…
Spectral Properties of Galaxies in Void Regions
Chenxu Liu, Danny Pan, Lei Hao +3
We present a study of spectral properties of galaxies in underdense large-scale structures, voids. Our void galaxy sample (75,939 galaxies) is selected from the Sloan Digital Sky S…
The Optical Luminosity Function of Void Galaxies in the SDSS and ALFALFA Surveys
Crystal M. Moorman, Michael S. Vogeley, Fiona Hoyle +3
We measure the r-band galaxy luminosity function (LF) across environments over the redshift range 0<<0.107 using the SDSS. We divide our sample into galaxies residing in large s…
An observational detection of the bridge effect of void filaments
Junsup Shim, Jounghun Lee, Fiona Hoyle
The bridge effect of void filaments is a phrase coined by Park & Lee (2009b) to explain the correlations found in a numerical experiment between the luminosity of the void galaxies…
An observational signal of the void shape correlation and its link to the cosmic web
Jounghun Lee, Fiona Hoyle
The shapes of cosmic voids are prone to distortions by the external tidal forces since their low-densities imply a lower internal resistance. This susceptibility of the void shapes…
The HI Mass Function and Velocity Width Function of Void Galaxies in the Arecibo Legacy Fast ALFA Survey
Crystal M. Moorman, Michael S. Vogeley, Fiona Hoyle +3
We measure the HI mass function (HIMF) and velocity width function (WF) across environments over a range of masses , and profile widths $1.3\log(km…
Photometric Properties of Void Galaxies in the Sloan Digital Sky Survey DR7 Data Release
Fiona Hoyle, Michael S. Vogeley, Danny Pan
Using the sample presented in Pan:2011, we analyse the photometric properties of 88,794 void galaxies and compare them to galaxies in higher density environments with the same abso…
Cosmic Voids in Sloan Digital Sky Survey Data Release 7
Danny C. Pan, Michael S. Vogeley, Fiona Hoyle +2
We study the distribution of cosmic voids and void galaxies using Sloan Digital Sky Survey Data Release 7 (SDSS DR7). Using the VoidFinder algorithm as described by Hoyle 2002, we…
