Priority-Based Stippling and its Stylization Applications

Mould, David; Li, Hua - In: International Journal of Creative Interfaces and … 8 (2017) 2, pp. 31-53

This article presents a new and efficient automatic method for structure-preserving stippling. The core idea is to concentrate on structure preservation by using a priority-based scheme that treats extremal pixels first and preferentially assigns positive error to lighter pixels and negative...

An Approach to Improve Generation of Association Rules in Order to Be Used in Recommenders

Hamidi, Hodjat; Hashemzadeh, Elnaz - In: International Journal of Data Warehousing and Mining (IJDWM) 13 (2017) 4, pp. 1-18

recommender systems. Combining sampling and parallelism in the process, the proposed method, in addition to help perform the … number of rules will be evaluated. One of the innovations of this article is the method of sampling of the database. Instead … of random sampling, information about the best users and items was isolated. After determining the precise amount of …

Integrating Systems Modelling and Data Science: The Joint Future of Simulation and ‘Big Data' Science

Pruyt, Erik - In: International Journal of System Dynamics Applications … 5 (2016) 1, pp. 1-16

Although System Dynamics modelling is sometimes referred to as data-poor modelling, it often is –or could be– applied in a data-rich manner. However, more can be done in the era of ‘big data'. Big data refers here to situations with much more available data than was until recently...

Analysis and Evaluation of a Framework for Sampling Database in Recommenders

Hamidi, Hodjat; Mousavi, Reza - In: Journal of Global Information Management (JGIM) 26 (2018) 1, pp. 41-57

In this paper the authors proposed a database sampling framework that aims to minimize the time necessary to produce a … sample database. They argue that the performance of current relational database sampling techniques that maintain the data … integrity of the sample database is low and a faster strategy needs to be devised. The sampling method targets the production …

Tolerance Analysis Supports Tolerance Assignment: The Industrial Case Study of Skillet

Polini, Wilma; Corrado, Andrea; Cavaliere, Costanzo - In: International Journal of Manufacturing, Materials, and … 8 (2018) 1, pp. 1-20

This work presents a method to support product design, since it shows how to use together tolerance assignment and analysis for choosing among different set of tolerances assigned to the same product. It starts from tolerance assignment that produces different sets of tolerances for the product...

Variation Sharing: A Novel Numeric Solution to the Path Bias Underestimation Problem of PLS-Based SEM

Kock, Ned; Sexton, Shaun - In: International Journal of Strategic Decision Sciences (IJSDS) 8 (2017) 4, pp. 46-68

The most fundamental problem currently associated with structural equation modeling employing the partial least squares method is that it does not properly account for measurement error, which often leads to path coefficient estimates that asymptotically converge to values of lower magnitude...

Hypothesis Testing with Confidence Intervals and P Values in PLS-SEM

Kock, Ned - In: International Journal of e-Collaboration (IJeC) 12 (2016) 3, pp. 1-6

E-collaboration researchers usually employ P values for hypothesis testing, a common practice in a variety of other fields. This is also customary in many methodological contexts, such as analyses of path models with or without latent variables, as well as simpler tests that can be seen as...

Advantages of Nonlinear over Segmentation Analyses in Path Models

Kock, Ned - In: International Journal of e-Collaboration (IJeC) 12 (2016) 4, pp. 1-6

The recent availability of software tools for nonlinear path analyses, such as WarpPLS, enables e-collaboration researchers to take nonlinearity into consideration when estimating coefficients of association among linked variables. Nonlinear path analyses can be applied to models with or without...

Structural Equation Modeling with Factors and Composites: A Comparison of Four Methods

Kock, Ned - In: International Journal of e-Collaboration (IJeC) 13 (2017) 1, pp. 1-9

Recent methodological developments building on partial least squares (PLS) techniques and related ideas have significantly contributed to bridging the gap between factor-based and composite-based structural equation modeling (SEM) methods. PLS-SEM is extensively used in the field of...
