University of Chicago researchers have developed an algorithm that has two functions: predicting crime and revealing a bias in police interventions in the United States.

University of Chicago researchers have developed artificial intelligence capable of predicting the locations and dates of crimes in several US cities.

According to the authors, it achieved a 90% success rate.

The software was “trained” on crime-related data from the city of Chicago (USA) compiled between 2014 and 2016 to create a predictive model. It then predicts future crimes committed in the following weeks.

Article published on June 30 In Science Journal Nature, indicating that the accuracy of localization is over 300 meters and is performed one week in advance. The city of Chicago wasn’t the only one concerned: Seven other major cities also underwent the exercise.

To combat the discriminatory biases of algorithms now recognized by various players in the sector, artificial intelligence does not identify potential suspects but only potential locations where crimes may take place.

Fight against bias

The purpose of this research is not only to develop a crime prevention tool. This should improve the development of police interventions. In fact, the work of these researchers highlights reduced police protection in some of the worst neighborhoods in several major cities, including Chicago and Los Angeles.

The report specifically highlights the higher number of arrests in more affluent neighborhoods compared to poorer neighborhoods over the same time period and study period.

“not that Minority Report“, defers Professor Ishanu Chattopadhyay, head of the study group. “The resources of law enforcement are not infinite. So they should be used in the best possible way. It would be better to know where the killings are likely to take place,” he said. With the Journal of Science New Scientist.

A team of researchers has also made its data public, As is its software, so that they can be analyzed by other experts. One way to make their algorithm transparent is to leave everyone the opportunity to detect and report potential biases.

“Rather than increasing a state’s power by predicting crime based on location and date, our tools help test whether law enforcement is affected by bias and better understand the processes by which urban policing evolves,” says Professor Chattopadhyay.

However, algorithms get a bad rap from privacy advocates. Questionable is their often inaccurate and biased use of bias. However, the researchers in question seem to be aware of these biases and declare above all that their aim is to highlight them in order to better eliminate them.

Chicago White Sox waste another strong Dylan Cease start, stranding 11 baserunners in a loss to cap a 3-5 trip

Andrew Vaughn blooped a single to right field in the third inning Thursday against the Kansas City Royals.

Seby Zavala, who began the inning with a single and advanced to second on a Luis Robert hit, got a late break on the play and only made it to third.

Still, the Chicago White Sox had the bases loaded with no outs.

It appeared that the Sox were heading toward a big inning. Instead, Royals starter Zack Greinke struck out Eloy Jiménez and José Abreu. Yasmani Grandal worked a full count before grounding out to shortstop Nicky Lopez, keeping the Sox scoreless.

It was that type of day — and trip — for the Sox.

They wasted another fantastic outing from Dylan Cease with a 5-3 loss to the Royals in front of 10,009 at Kauffman Stadium.

“We had (14) hits, had a real good effort,” Sox manager Tony La Russa said. “The guy on the mound (Greinke) has made a real good career at pitching out of that. Cease was outstanding but we got ready to play. We created the rallies, we were rallying late.

“It was the effort of the whole team. It’s tough to accept the loss but we took our shot.”

Cease allowed one run — a homer to Vinnie Pasquantino in the second inning — on three hits with eight strikeouts and two walks in six innings.

“Dylan threw phenomenal,” Vaughn said. “He’s been doing that for 14 straight starts. It stinks not to get him some runs.”

It was Cease’s 14th consecutive start allowing one or no earned runs, extending a major-league record (excluding openers).

“It was definitely a tough loss,” Cease said. “I thought I pitched pretty well, it was just one of those games. I always have the same mindset. I’m trying to limit as much as I can whether we’re up by eight or down. Really nothing changes.”

The Royals added three runs in the seventh against the Sox bullpen. Lopez drove in two with a single against José Ruiz. Those runs were charged to Joe Kelly, who exited with a lightheadedness after facing the first three batters of the innings. Lopez scored on an MJ Melendez single.

Grandal’s two-run homer in the eighth brought the Sox within 4-2. But the team left the bases loaded again in that inning.

The Royals added an insurance run in the eighth. Vaughn hit a solo homer in the ninth before Scott Barlow retired the next three as the Sox dropped three of four in the series.

It was a rough trip for the Sox, who went 3-5 against sub.-500 teams in the Texas Rangers and Royals. It was their first losing trip since May 31-June 5, when they went 2-4 against the Toronto Blue Jays and Tampa Bay Rays.

“It’s definitely not ideal but we’re not hanging our heads,” Cease said. “We’ve battled all year so we pretty much just have to keep battling and not get emotionally negative in any way. Just give it everything we’ve got.”

The Sox returned to .500 at 56-56, with the inability to produce runs again proving costly.

The first two batters reached in the second, followed by a flyout and double play. They had the three straight singles in the scoreless third.

La Russa said Zavala made the correct baserunning play on Vaughn’s single.

“The ball is caught by the right fielder and he’s halfway not tagging up we’d be upset,” La Russa said. “So he stayed close to the bag. All you can do, get to third base. I’d rather him get to third base with one out (if the) guy caught the fly ball.

“We still had the bases loaded. If he would have scored Robert would’ve been on third base, but I think he made the right baseunning play.”

The Sox had runners on the corners with one out in the sixth but came up empty. Even when they scored two in the eighth on Grandal’s homer, they failed to tack on, leaving the bases loaded later in the inning.

The Sox went 2-for-13 with runners in scoring position.

“We got (14) hits,” La Russa said. “You don’t get those hits luckily. You create opportunities. You follow Zack Greinke’s career, he pitches out of a lot of jams. And he pitched out (of) bases loaded and two on against the middle of our lineup. That’s tough to take. But tip your cap to him.”

The Sox stranded stranded 11 baserunners while falling to 8-8 during their stretch of 19 games against teams with sub .500 records. That stint concludes with three games this weekend against the Detroit Tigers at Guaranteed Rate Field.

“It’s never good to lose a series,” Vaughn said. “We’re barely hanging around .500. (We’ve) got to keep going at it.”
