Assessing recall of personal sun exposure by integrating UV dosimeter and self-reported data with a network flow framework
Fig 4
The importance of order in assignment and NFA solution.
(a) The left figure shows misalignment of two self-reported events SR1 and SR2 with the sensor events. The top right part of the figure shows the reduction in false negative minutes when assigning SR1 first to its nearest neighbor. The bottom right part of the figure shows what happens when assigning SR2 first to its nearest unassigned neighbor. (b) Illustration of network flow solution. The top figure shows one path (in red) that enables a flow or alignment of 15 minutes (allowing only 15 units to flow through the first edge from the source to the sink node). Maximum flow is illustrated by the green arrows in the bottom figure, which allows 15 minutes along path 1 and 54 minutes along path 2.
