Accuracy Assessments in the Era of Machine Learning

Type: Paper
Sponsor Groups: Remote Sensing Specialty Group
Organizers: Eliza Bradley, Kevin Magee
Chairs: Kevin Magee


Classification accuracy assessments are arguably the most important act of the classification process – without it, the results are an uncertain collection of opinions. It is the measurement of error, both thematic and spatial, that provides confidence in the quality of the data, its relative strengths and weaknesses across classes, its locational reliability, and allows scientists a means to communicate its value and limitations for particular applications not only to one another, but to customers and policy makers. Working towards a greater understanding of how bias can differentially impact modern classification methods such as deep CNNs is key to advancing the state of this field, and ensuring that we are properly assessing and mitigating bias across the wider computer vision and remote sensing community.
