The "Algorithm"

We make it a habit not to link to the New York Times, but even good habits get bent sometimes. This article goes into the mysterious algorithm that runs much of the Department operations via the SSL - Strategic Subject List - and which is currently the subject of a number of FOIA requests:
  • Gun violence in Chicago has surged since late 2015, and much of the news media attention on how the city plans to address this problem has focused on the Strategic Subject List, or S.S.L.

    The list is made by an algorithm that tries to predict who is most likely to be involved in a shooting, either as perpetrator or victim. The algorithm is not public, but the city has now placed a version of the list — without names — online through its open data portal, making it possible for the first time to see how Chicago evaluates risk.

    We analyzed that information and found that the assigned risk scores — and what characteristics go into them — are sometimes at odds with the Chicago Police Department’s public statements and cut against some common perceptions.

The article drills down into the working of the violence equations, mostly by working backwards from results and what limited information they derive from Department and City press releases. The FOIA request may reveal more of the methodology, but regardless, it's an OK read from a left-leaning anti-American "progressive" rag.

Hahaha, you need an algorithm for this? If I were drunk, standing on my head, I could tell you who is at risk as well as who the offender is. Hell, I'll even lay 8-5 odds on the hood.

So what.

Jonathan Lewin has yet to produce anything meaningful for the police officer.

Will someone in the private sector please give this worthless whiner a job.

The WSJ, NYT and the Washington Post are the three best sources for news in this country, regardless of your political persuasion. Christian Science Monitor isn't bad either.

Want to figure things out for being safe?? Look at the Hey Jackass graphic for the Deadliest Hoods. Stay out of them (most of Chicago) or get a houseboat and live on Lake Michigan as no one is being shot on the lake. Algorithms are a creation of statisticians and they make playing with numbers an art form.

If God wrote an article in the New York Times I still would not read it. The New York Time blows, and there is really no meaningful articles written without a left twist. Anything you may think is interesting in the New York Times has a progressive motive attached.

What's the Stats on how many of the 1400 SSL's re-committing crimes and released over and over again?
Think the Juveneile records of the 3 would shot up the schoolyard last week would ever make an algorithm?
More bullshit talk from the liberals, no action.
Algorithms don't solve violent crime - police, stern judges and jail does.
But the Elected Politicans don't want police.
They want Fear.

How many able bodied sworn law enforcement officers and merit hack supervisors are being holed up Mon-Fri at 35th St crunching numbers for Rahm Emanuel and Jughead ?

Stay fetal.

They took a shithead and backwards engineered an equation that shows he is a shithead. Something a seasoned cop could do in seconds of talking to one of them. They are trying to replace good police work and experience with house mouse merit strategies. Look where it got us. Let's shoot for 1000 dead this year.

If predictive analysis really worked, no company would ever go bankrupt, there would never be a depression, everyone would have sock that always made money. The problem with predictive analytics is it can't predict the future. It can't predict a plane flying into the World Trade Center, weather, crazy people who are not predictable.

Al Gore & The Rhythm was booked for Hillary's Victory Party that never came, like his 2007 prediction summer in the North Pole could be “ice-free by 2013”...due to global warming. Not everyone is as sharp as "I'm with her" Nobel winner Gore (or global obama) but predicting who's going to shoot or get shot-kilt is Chicago is like betting on a roulette wheel without the red.

There is no gun violence in Chicago. There is violence in Chicago. People resort to violence because that is how they were raised. If people want the violence to stop, they can stop being violent.

You are correct, Lewin did not create the Algorithim, but he is the 1 pushing this algorithim to produce stats that help Lewin keep the BS flowing so he can pull in the big bucks. Lewin is a self-centered arrogant POS. The only thing that matters to Lewin is Lewin.

Predictive analysis worked once, contrary to one or two of the statements above. In the 1990s, the Boston police predicted their way out of any youth homicides for a year or two or three.

Problem was, you can predict the kids who need the intervention the most, but you still need the police, schools, religious institutions, social workers and agencies, and all the rest to do their part. They got it to work for a few years in Boston, and I think overall its probably still the framework. But in Chicago? Lolololol. Which schools? Which religious institutions? Which social workers and agencies? And that's assuming the CPD part of it would work, by intervening with the right kids and keeping tabs and intervening with them systematically.

Anyway, just wanted to address the idea that it doesn't work or will never/would never work. It worked. Once. In Boston.

Dilbert is in charge of that section. He's supposed to be smart. The buck stops with him. No, I don't like a person who wastes officers time and man power with bullshit. He can be working on getting better tools in the officers hands for day to day service. Instead we have 8 ball since from a bunch of college kids who haven't worked a day in their life but are more than qualified to tell a working person how and what best works. About the only thing Dilbert is good for is saying no to every project he didn't bring to the table. Create it or not he's ultimately responsible for the implementation or denial of an application.

WTF SCC, I just ran my name and have an SSL score 459. WTF is going on here, I don't think . . ., oh wait, . . I see, I live in $hicago! Yeah, that's it, I live in Chicago and my chances of getting robbed or shot, or killed are exponentially high. Oh wait, I'm a citizen, I thought that was just for $h!the@ds.

Wouldn't it be great if people throughout Chicago could go online and find out what their score would be based on where they live.
