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.
