Generalization of Linked Canonical Polyadic Tensor Decomposition for Group Analysis

2019

Real-world data are often linked with each other since they share some common characteristics. The mutual linking can be seen as a core driving force of group analysis. This study proposes a generalized linked canonical polyadic tensor decomposition (GLCPTD) model that is well suited to exploiting the linking nature in multi-block tensor analysis. To address GLCPTD model, an efficient algorithm based on hierarchical alternating least squa res (HALS) method is proposed, termed as GLCPTD-HALS algorithm. The proposed algorithm enables the simultaneous extraction of common components, individual components and core tensors from tensor blocks. Simulation experiments of synthetic EEG data analysi…

Using schematic representation of resource systems to examine how first year engineering students use resources in their studies of mathematics

2018

International audience; Very little research has been done on how students use resources when studying mathematics. My project aim to examine this both quantitatively and qualitatively. The qualitative data collection includes hierarchical focus interviews and schematic representation of resource system, with the intent to impose as little terminology as possible on the students.

Natural induction: An objective bayesian approach

2009

The statistical analysis of a sample taken from a finite population is a classic problem for which no generally accepted objective Bayesian results seem to exist. Bayesian solutions to this problem may be very sensitive to the choice of the prior, and there is no consensus as to the appropriate prior to use.

Hierarchical Analysis of Forms of Support for Employees in the Field of Health Protection and Quality of Work during the COVID-19 Pandemic and the De…

2022

Issues of employee support during the COVID-19 pandemic and the post-pandemic period are of an interdisciplinary nature. Moreover, these should be considered from both an epistemological and a practical perspective. The aim of this study was to determine what forms of support for employees in terms of health and quality of work were provided by employers during the pandemic and what forms of support will be expected by employees after it ceases. The research process was carried out in two stages: primary and secondary exploration and quantitative clarification. In the first stage, a systematic review of the literature and a critical analysis of the so-called grey literature was performed. I…

The Timecourse of Sentence Processing in the Brain

2015

This chapter discusses the current state of the art with regard to the timecourse of sentence processing in the brain. It outlines the challenges associated with studying timecourse information at the sentence level from a neurobiological perspective and describes competing theoretical and empirical perspectives in this domain. In addition to drawing on findings from neurophysiological methods (electroencephalography [EEG]; magnetoencephalography [MEG]), insights from eye movement measures during natural reading are also taken into account. The chapter concludes that while we are currently unable to make absolute claims about the timecourse of sentence processing from a neurobiological pers…

Fuzzy Systems Based on Multispecies PSO Method in Spatial Analysis

2012

We present a method by using the hierarchical cluster-based Multispecies particle swarm optimization to generate a fuzzy system of Takagi-Sugeno-Kang type encapsulated in a geographical information system considered as environmental decision support for spatial analysis. We consider a spatial area partitioned in subzones: the data measured in each subzone are used to extract a fuzzy rule set of above mentioned type. We adopt a similarity index (greater than a specific threshold) for comparing fuzzy systems generated for adjacent subzones.

Unveiling the environment and faint features of the isolated galaxy CIG 96 with deep optical and HI observations

2018

Context. Asymmetries in atomic hydrogen (HI) in galaxies are often caused by the interaction with close companions, making isolated galaxies an ideal framework to study secular evolution. The AMIGA project has demonstrated that isolated galaxies show the lowest level of asymmetry in their HI integrated profiles compared to even field galaxies, yet some present significant asymmetries. CIG 96 (NGC 864) is a representative case reaching a 16% level. Aims. Our aim is to investigate the HI asymmetries of the spiral galaxy CIG 96 and what processes have triggered the star-forming regions observed in the XUV pseudo-ring. Methods. We performed deep optical observations at CAHA1.23m, CAHA2.2m and V…

Grammar types in language explain tone sequence processing in music

2009

In this ERP study, linear and center-embedded musical sequences are built according to two artificial grammar types in language, named finite state grammar (FSG) and phrase structure grammar (PSG). The aim is to prove if neural sources and processing mechanisms for artificial grammar settings across domains are the same. Isochronous pitch sequences were constructed by two interval categories (3rd and 6th) in upward and downward direction. FSG sequences, which have the general form ABAB in artificial grammar, are translated into “small up/small down/large up/large down”. PSG sequences of form A[AB]B are transposed to “small up/large up/large down/small down”. In two ERP recordings testing FS…
