Canonical Correlation Analysis for Longitudinal Data
… commonly occur in applications. Statistical analysis of these data is usually done using a canonical correlation analysis (CCA). Occurrence of these data at multiple occasions or conditions leads to longitudinal multivariate data for a CCA. We address the problem of canonical correlation …

Multi-modal Multi-Level Neuroimaging Fusion with Modality-Aware Mask-Guided Attention and Deep Canonical Correlation Analysis to Improve Dementia Risk Prediction
… incorporates Random Modality Masking and Deep Canonical Correlation Analysis (DCCA) for cross-modal feature alignment. Experiments on the ADNI dataset demonstrate that the proposed MRI+PET (MAMGA+DCCA) model achieves a balanced accuracy of 0.998 and an AUC-ROC of 0.999 in distinguishing stable …

Multiview feature learning for speech recognition
… consider a multiview learning approach based on canonical correlation analysis to learn linear transformations of the acoustic features that are maximally correlated with the data. We propose simple approaches for combining information shared across the views with information that is private to …

A Bayesian Fusion Approach and Its Application to Integrating Audio and Visual Signals in HCI
Finally, kernel canonical correlation analysis (CCA) is developed to model nonlinear or high-order correlations between signals from two sources. Kernel CCA uses kernel principal component analysis (PCA), which elegantly combines a nonlinear transformation and linear PCA into a one-step …

Patterns of association between real-world performance and measures of executive function
This study examined the canonical relationships between a set of real-world performance measures and a set of executive function measures with a sample of community based individuals with schizophrenia (N=80). Participants were given a battery of cognitive tests and evaluated with a real-world …

Cognitive Styles and Measured Occupational Preferences of College Freshmen and Sophomores
… nine linear hypotheses were tested by zero-order correlation and stepwise-regression analysis, respectively. The ninth general linear hypothesis was tested by means of canonical-correlation analysis.</p> <p>Findings. Results of the study indicated that field independence was statistically …

An investigation of social isolation and well-being among the elderly
… that measured material comforts. Results of a canonical correlation analysis revealed a significant relationship among the indicators and well-being. Further analysis using multiple regression revealed a weak relationship between perceived life satisfaction and closeness with confidants. The …

Examining the relationship among context, cognition, and conflict management in the workplace
… Analyses of the data included multivariate analysis of variance (MANOVA), canonical correlation analysis, and hierarchical multiple regression. The results of MANOVA were that context had modest effects on cognition and behavioral intention, examined in separate analyses. The conflict type, …

Kernel Machines are Not Black Boxes - On the Interpretability of Kernel-based Nonparametric Models
… importance measure for supervised regression analysis, and is inapplicable for unsupervised models. This thesis overcomes these issues by using the gradient of kernel-based nonparametric functions to interpret kernel-based models. In particular, the gradient of a kernel regression function can …

Building a Nonparametric Model After Dimension Reduction
… The dimension reduction procedure is based on a canonical correlation analysis on the predictor variables and a spline basis generated for the response variable. One important question in dimension reduction is to decide on the number of effective dimensions needed. We study four tests of …

Canonical Correlation and Correspondence Analysis of Longitudinal Data
… vectors is an important problem in statistics. Canonical correlation coefficients are used to study these relationships. Canonical correlation analysis (CCA) is a general multivariate method that is mainly used to study relationships when both sets of variables are quantitative. When the …

Spatial Patterns in a 40-year-old Slash Pine (Pinus elliottii Engelm.) Forest in the Coastal Plain of South Carolina
… and relationships were explored using Pearson's correlation tests, canonical correlation analysis, variogram modeling and kriging. The average range of spatial autocorrelation for the forest floor variables was >45 m, while that for soil variables was 12 m. Woody stem basal area exhibited spatial …

Canonical correlation of shipping forward curves
… the Samuelson hypothesis. Principal Components Analysis and Canonical Correlation analysis were used to demonstrate how the task of explaining the various shipping forward curves can be simplified substantially and how very high correlations can be achieved between shipping forward curves. The …

Structure and geometry in sequence-processing neural networks
… will use various techniques of representational analysis to understand the nature of neural-network based language modelling. To introduce the concept of linguistic probing, we explore how various language features affect model representations and long-term behavior through the use of linear …

Religiosity, Spirituality and Attendance at Religious Services among Recreational Drug Users: A Sub-Analysis of the Drugnet Survey
This study is a sub-analysis ofthe previously collected cross-sectional DRUGNET survey data. The sample included 1,178 current users of illicit drugs and 389 former users. This study was delimited to U.S. citizens, aged 18 years and older, who completed the DRUGNET survey (n =1,567). DRUGNET was a …
