Frailty in the Elderly: Conceptual Analysis1

In recent decades, it has been observed an increase in scientific production on frailty in the elderly. Nevertheless, there is no consensus on the definition and use of that concept. Thus, in view of the need to clarify it, the objective of this study was to analyze the concept frailty in elderly people, identifying antecedents, attributes and consequences of the phenomenon. The study was guide...

Exploring Subjectivity in Hazard Analysis1

In an earlier paper (Redmill 2002) risk analysis was defined as comprising four stages scope definition, hazard identification, hazard analysis, and risk assessment. In the first stage, the scope and terms of reference of the analysis are defined. In the second, the hazards that could lead to breaches of safety are identified. In the third, the risks associated with the hazards are determined, ...

Kernel Canonical Correlation Analysis1

This paper introduces a new non-linear feature extraction technique based on Canonical Correlation Analysis (CCA) with applications in regression and object recognition. The non-linear transformation of the input data is performed using kernel-methods. Although, in this respect, our approach is similar to other generalized linear methods like kernel-PCA, our method is especially well suited for...

Adaptive Nonstationary Regression Analysis1

The problem of finding the most appropriate subset of features or regressors is the generic challenge of Machine Learning problems like regression estimation or pattern recognition. We consider the problem of timevarying regression estimation, which implies also the inevitable necessity to choose the individual appropriate levels of model volatility in each of regressors, ranging from the full ...
