The Hidden Inconsistencies Introduced by Predictive Algorithms in Judicial Decision Making [article]

Travis Greene, Galit Shmueli, Jan Fell, Ching-Fu Lin, Mark L. Shope, Han-Wei Liu
2020 arXiv   pre-print
These inconsistencies threaten to violate the principle of treating similar cases similarly and often arise from the need to operationalize legal concepts and human behavior into specific measures that  ...  We also consider the issue of inconsistencies due to the use of algorithms in light of current trends towards more autonomous algorithms and less human-understandable behavioral big data.  ...  The goal of this process is to achieve an optimal balance between model complexity and fit, effectively detecting just the predictive signal in the training data and discarding noise.  ...
