    If you were hoping that Wisconsin would open up the sentencing algorithm it uses to help determine prison time, you're about to be disappointed. The state's Supreme Court has ruled that the use of the the COMPAS algorithm doesn't violate your constitutional right to due process. The decision rejected plaintiff Eric Loomis' complaints that the code is both proprietary (thus preventing him from challenging its accuracy) and was too central to his 6-year prison term. There were "other independent factors" leading to the sentence, the Supreme Court says, and you don't need to reveal the algorithm's source code when it's only one consideration among many.

    Many people are nervous about the prospect of using algorithms to predict crime, and a legal battle in Wisconsin is illustrating why. The state's Supreme Court is close to ruling on an appeal from Eric Loomis, who claims that the justice system relied too heavily on its Compas algorithm to determine the likelihood of repeat offenses and sentence him to 6 years in prison. His attorneys claim that the code is "full of holes," including secret criteria and generic decisions that aren't as individually tailored as they have to be. For instance, they'll skew predictions based on your gender or age -- how does that reflect the actual offender?
