The availability heuristic is a strategy that people use to make quick decisions but often lead to systematic errors. We propose three ways that visualization could facilitate unbiased decisionmaking. First, visualizations can alter the way our memory stores the events for later recall, so as to improve users' long-term intuitions. Second, the known biases could lead to new visualization guidel...

Bush yam has been underutilized and underrated for long due to its undesirable attributes or traits, hence the commercial food security potentials of crop have downgraded unexploited. This paper, therefore, explored Ghanaian bush consumers’ decisionmaking behaviour towards crop’s cultivar selection values they place on diverse attributes. With aim examining preference willingness pay yam, we de...

AbstractAiming at complexity and uncertainty of actual decision-making environment, this study proposes a multiple attribute decision-making model of grey target based on positive and negative bull’s-eye. Firstly, it defines that the optimal effect vector and the worst effect vector of grey target decision are respectively positive, negative bull’s-eye of the grey target; secondly, comprehensiv...

(a) Attribute 4, CHAS, is the only binary attribute. (b) Attribute 13—LSTAT—has the highest negative correlation and attribute 6—RM—has the highest positive correlation with the target attribute.

Because of the complexity of decision-making environment, the uncertainty of fuzziness and the uncertainty of grey maybe coexist in the problems of multi-attribute group decision making. In this paper, we study the problems of multi-attribute group decision making with hybrid grey attribute data (the precise values, interval numbers and linguistic fuzzy variables coexist, and each attribute val...

What role(s) do emotions have in choice preference? Individuals’ choices depend on their memories and cognition but also on their current emotional state. Emotions can play a necessary functional role in decisionmaking, but in doing this, emotions can alter the stability of the process. The argument for a necessary functional role of emotions is supported by converging evidence from neuropsycho...

Based on our previous work we propose to track multiple ground targets with GMTI (GroundMoving Target Indicator) sensors as well as with imagery sensors. The scope of this paper is to fuse the attribute type information given by heterogeneous sensors with DSmT (Dezert Smarandache Theory) and to introduce the type results in the tracking process to improve its performances.
