Interval-valued aggregation functions based on moderate deviations applied to Motor-Imagery-Based Brain Computer Interface
This work provides an incremental improvement in aggregation techniques for interval-valued data, specifically benefiting decision-making in Motor-Imagery Brain Computer Interface systems.
This paper introduces interval-valued moderate deviation functions to measure similarity and dissimilarity in interval-valued data. These functions are then used to construct interval-valued aggregation functions, which were applied to Motor-Imagery Brain Computer Interface frameworks, achieving improved results compared to other aggregation methods.
In this work we study the use of moderate deviation functions to measure similarity and dissimilarity among a set of given interval-valued data. To do so, we introduce the notion of interval-valued moderate deviation function and we study in particular those interval-valued moderate deviation functions which preserve the width of the input intervals. Then, we study how to apply these functions to construct interval-valued aggregation functions. We have applied them in the decision making phase of two Motor-Imagery Brain Computer Interface frameworks, obtaining better results than those obtained using other numerical and intervalar aggregations.
