Twitter scrapped its face detection algorithm in 2017 for a saliency detection algorithm, which is made to foretell an important a part of a picture. A Twitter spokesperson said today that no race or gender bias was present in analysis of the algorithm earlier than it was deployed “however it’s clear now we have extra evaluation to do.”
Twitter engineer Zehan Wang tweeted that bias was detected in 2017 earlier than the algorithm was deployed however not at “vital” ranges. VentureBeat reached out to Twitter for added particulars in regards to the 2017 analysis and steps the corporate will take to reassess the algorithm. We are going to replace this story once we hear again.
I’m wondering if Twitter does this to fictional characters too.

Algorithmic bias researcher Vinay Prabhu, whose current work led MIT to scrap its 80 Million Tiny Images dataset, has created a technique for assessing the algorithm and can share outcomes through the just lately created Twitter account Cropping BiasCropping Bias.
