Justice in the Age of Big Data

In Chapter 5, entitled “Justice in the Age of Big Data,” Cathy O’Neil discussed inequality in the justice system and the important role of WMD in the American justice system.

The author uses the example of patrolling police and criminals during the crime period, Ali discusses the AI ​​software algorithm in detail. The software algorithm can determine the best cruise route for the police in advance based on the crime prediction. Of course, it can also be calculated based on the criminal’s trajectory to help the parliamentarians decide on specific protective measures. However, this also affects slums that are often passed by patrols, and more and more arrests have led to worsening poverty. O’Neil also added that there is a phenomenon today where wealthy young whites will escape from the police because of the gray area of ​​the law. However, people with other skin colors such as Latins or blacks are not. We can prevent the things she mentioned in the article from happening by reasonably distributing police forces, and check which areas are hotspots and which crimes are being committed over a period of time, so as to better understand the community.

My biggest gain is that as the person who initiates the model training, we should give the machine rewards instead of letting the machine generate it by itself, because the machine just follows the instructions of the training model and executes it. Therefore, the model will directly reflect the situation of the police when patrolling the community, because the model is a machine and the police poet, if the police have a bad idea in a poor community.
