L2hforadaptivity Ef F1 F3 F5 !!top!! Review

The core of the string is adaptivity (ability of a system to modify its behavior in response to changing conditions). The prefix l2h likely stands for "Low-to-High" (e.g., low-to-high frequency, low-to-high resolution, or low-to-high complexity). The terms ef , f1 , f3 , f5 appear to be frequency bands, feature sets, or filter identifiers .
