A method (1500) and apparatus (700, 2300, 2400) for aggregating two or more input signals with a versatile reconfigurable signal aggregator. The aggregator (700, 2300, 2400) is reconfigured by adjusting a control signal λ, and can emulate a range of union type signal aggregators, a range of intersection type signal aggregators, and a continuum of functions between the two, including a signal averager. The versatility of the aggregator (700, 2300, 2400) allows systems in which the aggregator (700, 2300, 2400) is incorporated to be highly adaptable, and thereby fosters improved machine learning.
