Real-Time Emotion Classification Using EEG Data Stream in E-Learning Contexts

Arijit Nandi, Fatos Xhafa, Laia Subirats, Santi Fort
2021 Sensors  
For this, we propose a real-time emotion classification system (RECS)-based Logistic Regression (LR) trained in an online fashion using the Stochastic Gradient Descent (SGD) algorithm.  ...  Learners' emotions are crucial for e-learning system because they promote or restrain the learning.  ...  The weights w are updated based on the gradient of the empirical risk (E m ( f )).  ...

Product Lines for Digital Information Products

2007 Wirtschaftsinformatik  
The focus on sets of similar products is indeed realistic, as can be observed in e-learning; for example one can think of the digital content for an information systems course which is offered for different  ...  In addition, the DWE offers the possibility to create a marking graph based on the edited workflow 1 .  ...  They were used as a basis to create more abstract models, such as the conceptual product line model or the construction specification (cf.  ...

Dynamic Decision Making and Race Games

Shipra De, Darryl A. Seale
2013 ISRN Operations Research  
To address such concerns, we study dynamic decision making with respect to a simple race game, which has a computable optimal strategy.  ...  If the number one appears on any of the dice, the player receives no points for his turn; otherwise, the sum of the numbers appearing on the dice is added to the player's score.  ...  During the evaluation process decision makers will assign a decision weight to each of the probabilities from the editing stage and a subjective value to each of the possible outcomes-in essence, the deviation  ...

Iterated Local Search

Helena Ramalhinho Dias Lourenço, Olivier C. Martin, Thomas Stutzle
2001 Social Science Research Network  
The essential idea of Iterated Local Search lies in focusing the search not on the full space of solutions but on a smaller subspace defined by the solutions that are locally optimal for a given optimization  ...  How effective this approach turns out to be depends mainly on the choice of the local search, the perturbations, and the acceptance criterion.  ...  Single Machine Total Weighted Tardiness Problem (SMTWTP) Congram, Potts and van de Velde [18] have presented an ILS algorithm for the SMTWTP based on a dynasearch local search.  ...

Programming language abstractions for extensible software components

Matthias Zenger
2005
This document was set in ITC Charter using the L A T E X typesetting system on MacOS X. The graphical content was produced with OmniGraffle Professional.  ...  Often such approaches are based on special middleware which explicitly supports the dynamic evolution of systems.  ...  For this reason, component-based systems are often required to support some form of dynamic linking.  ...

A Grammar of Penange (Dogon, Mali)

Jeffrey Heath
2016
For final-nonhigh-vowel verbs (‘go in’, ‘slaughter’, ‘shake’), this form is based on the O-stem. For final-high-vowel verbs (‘do’), it is based on the U-stem.  ...  Based on the position of 1st/2nd person subject pronominals, the capacitative is affiliated with the perfective systems.  ...

Resources and decisions: Peasant farmer agricultural management and its relevance for rural development planning in Kwara State, Nigeria

David Oluwayomi Atteh
1980
The method of investigation is centred on the 'triad' strategy of 'observing', 'listening and recording' and 'asking questions' proposed by Whyte (1977) as the proper basis for the study of environmental  ...  Many explanations offered for 'traditional' farming in Africa often concern production patterns without a serious attempt at understanding the underlying decision-making process.  ...  One is that farmers are thinking about the macroscopic features of the farming system.  ...

Central Asian and Yanbian Korean in comparative perspective

Simon George Barnes-Sadler
2016
When the explicit examination of a linguistic system is embarked upon, attitudes towards and perceptions of that system are hugely influential in its evaluation (e.g. Inoue 1999).  ...  These evaluations will for the basis for our qualitative comparison of VYK and KM.  ...
