SKOPE-IT (Shareable Knowledge Objects as Portable Intelligent Tutors): overlaying natural language tutoring on an adaptive learning system for mathematics
TL;DR: Across all users, learning was most strongly influenced by time spent studying, which correlated with students’ self-reported tendencies toward effort avoidance, effective study habits, and beliefs about their ability to improve in mathematics with effort.
Journal ArticleDOI
Handling Big Data Using a Data-Aware HDFS and Evolutionary Clustering Technique
TL;DR: A data-aware module for the Hadoop eco-system is proposed and a distributed encoding technique for genetic algorithms efficient data processing is proposed to manage the distribution of data and its placement based on cluster analysis of the data itself.
Proceedings Article
Exploring real-time student models based on natural-language tutoring sessions.
TL;DR: This research explores the feasibility of mapping concept-focused tutoring sessions to knowledge components, by breaking sessions down into features that are integrated into a session score, and finds verbosity was a key predictor even after accounting for the semantic match.
Proceedings ArticleDOI
Distributed evolutionary approach to data clustering and modeling
TL;DR: A framework for the application of distributed genetic algorithms for detection of communities in networks, which proposes efficient ways of encoding the network in the chromosomes, greatly optimizing the memory use and computations, resulting in a scalable framework.
Proceedings ArticleDOI
Distributed genetic algorithm to big data clustering
TL;DR: A mapping between graph clustering problem and data clustering is described using genetic algorithms and multi-objective optimization as well as distributed graph stores to transform big data into Distributed RDF graphs and produce clusters by maximizing graph modularity as a main objective.
