Twitter Ditches Biased Image Cropping AI

Twitter has pretty much abandoned an image-cropping AI after discovering that automated system was biased. Users had complained it had a preference toward showing pictures of white people in previews of tweets.

A blog post from Rumman Chowdhury, software engineering director at Twitter, stated that Twitter concluded the AI was biased after testing it for both gender and race biases. The post and research essay attached detailed that the cropping system when tested on random images demonstrated a preference for white people over black people and men over women.

Chowdhury stated that their conclusion is some tasks are best left to people and are not a good task for AI.

The research conclusions come months after the company said it would investigate the issue with its AI image cropping program.

Twitter, in March, started testing a new method to show a full image, rather than auto cropped previews, on mobile devices when a user tweeted a single image. The program would auto-crop the preview image people saw before clicking the preview for the full image. However, the program was prone to errors.

Now they rely on saliency which requires knowing what area of the image the eye is drawn to first.

 

NextDoor

Have you joined nextdoor.com yet? We received a postcard in the mail about it, so we joined. The call themselves “The private social network for your neighborhood.” They have a website and an app. “When neighbors start talking, good things happen.”

Some of the posts we’ve seen are things like “does anyone have a recommendation for a ___” (fill in the blank). It could be a painter, a handyman, a babysitter, etc. You can see local events, yard sales, people can post things to sell, and a host of other things like lost pets, pets for adoption, elderly asking for help with yard work.

Some of the posts are a little more serious, like reporting breakins or robberies. Of course there are also ads.

On a lighter note, it is fun to see of the more obnoxious posts. Like “Crazies on motorcycles” or “Blue heron eating pond fish”. If you really want to have fun with it, you can follow @bestofnextdoor on twitter.com. They have culled some of the more outlandish posts from around the country and posted them for people to see. You will see some posts with added phrases such as “This is not a dating app” or “Nextdoor is twitter for old people”. Have fun.

Other Uses for Social Media

Maybe you love, maybe you hate it but social media is here to stay. Many people used it as their lifeline during the past storm in Texas, known as Harvey. Many used Twitter or Facebook or Instagram to let people know they were in stuck and needed to be rescued. Still others used social media to let people know they were able to help.

The U.S. Coast Guard preferred for people to call them or 911 but people had trouble getting through. People even turned to Airbnb to offer their homes as shelters for those in need. The Hurricane Harvey Texas Rescue Facebook group offered ways to help those trapped or in need of rescue.

Shop from Twitter?

Amazon has made shopping even easier. Suppose a friend or acquaintance mentions an product on Twitter. If it’s an Amazon product, and you want to buy it, instead of clicking on it and then adding to your cart, you can hit reply and add #AmazonCart and it will automatically add it to your cart. It will not automatically purchase it so you don’t have to worry about impulse purchases. You need to connect your Amazon account to your Twitter account in Social settings in Twitter.
