In this paper we present two analog VLSI circuits that implement current mode winner-take-all (WTA) networks with lateral excitation. We describe their principles of operation and compare their performance to previously proposed circuits. The desirable properties of these circuits, namely compactness, low power consumption, collective processing and robustness to noisy inputs make them ideal fo...

A novel architecture for winner-take-all (WTA) and looser-take-all (LTA) circuits is proposed. As compared with other realisations, the LTA does not require input subtraction from a reference, which decreases accuracy and input dynamics. The architectures have been designed using the gm/ID methodology. As it will be shown, this method allows a rapid new dimensioning when specifications are modi...

The temporal property`to-always' has been proposed for specifying progress properties of concurrent programs. Although thèto-always' properties are a subset of thèleads-to' properties for a given program, `to-always' has more convenient proof rules and in some cases more accurately describes the desired system behavior. In this paper, we give a predicate transformer wta, derive some of its prop...

In this paper, a novel genetic algorithm, including domain specific knowledge into the crossover operator and the local search mechanism for solving weapon-target assignment (WTA) problems is proposed. The WTA problem is a full assignment of weapons to hostile targets with the objective of minimizing the expected damage value to own-force assets. It is an NP-complete problem. In our study, a gr...

We exhibit three non-standard cases of preference reversal (PR) between choices and valuations of bets. The endowment effect arises as a surprising consequence of the WTA/WTP disparity when the probabilities of winning get close to certainty. We consider a new theory of choice under risk, cognitive consistency (CC) theory, which can predict both standard and non-standard cases of PR, the WTA/WT...

This paper presents an experimental study analyzing common consequence effects with binary choice, willingness-to-pay (WTP), and willingness-to-accept (WTA). Consistent with previous research we do not find clearcut evidence of fanning out in the absence of certainty effects. Violation rates of EU are more pronounced for WTP and WTA than for choice data. Moreover, there is a strong tendency for...

In this study, we present a hardware implementation of the conscience mechanism in Kohonen self-organizing maps. The proposed realization of the conscience mechanism is important to the functioning of the neural network as it eliminates so-called dead (inactive) neurons. As a result the network learning, the level quantization error can be reduced. The conscience mechanism and the Winner Take A...
