Garrett Butts details military drone innovation effort aimed at speeding deployment and reducing cost in an exclusive interview with Fox News Digital. As the war between Israel and Iran intensifies, one Army drone expert is warning that the U.S. must stay ready, and fast. Garrett Butts is helping lead the charge by building smarter, cheaper unmanned aircraft systems (UAS) in-house for the battlefield. In an exclusive interview with Fox News Digital on Tuesday, Butts described how his team is creating drone technology from scratch, often using parts it took nearly a year to legally obtain. "We're a transformation and contact unit," said Butts, who serves with the 1st Cavalry Division.

The theory of belief functions is widely used for data from multiple sources. Different evidence combination rules have been proposed in this framework according to the properties of the sources to combine. However, most of these combination rules are not efficient when there are a large number of sources. This is due to either the complexity or the existence of an absorbing element such as the total conflict mass function for the conjunctive based rules when applied on unreliable evidence. In this paper, based on the assumption that the majority of sources are reliable, a combination rule for a large number of sources is proposed using a simple idea: the more common ideas the sources share, the more reliable these sources are supposed to be. This rule is adaptable for aggregating a large number of sources which may not all be reliable. It will keep the spirit of the conjunctive rule to reinforce the belief on the focal elements with which the sources are in agreement. The mass on the emptyset will be kept as an indicator of the conflict. The proposed rule, called LNS-CR (Conjunctive combinationRule for a Large Number of Sources), is evaluated on synthetic mass functions. The experimental results verify that the rule can be effectively used to combine a large number of mass functions and to elicit the major opinion.
