Trust and Distrust: A Reputation Ratings Approach
(2016)
Agents’ reputation ratings in a social network form a real valued matrix which is discounted with singular
value decomposition (SVD) to estimate the trust and distrust levels of agents. SVD eliminates noise as future ...
The Effect of the Operational Parameters on the Draft Requirement of Ripping in a Sandy Clay Soil
