Key Recent Developments
ElliQ is 93-year-old Juanita's friend. She's also a robot
What: Interview with a 93-year old woman, Juanita, who has used a commercial, AI-powered robot companion called ElliQ for about 2 years. ElliQ is advertised as a “sidekick for happier ageing” and is aimed at older adults without dementia. Unlike Alexa, ElliQ is proactive.
Key Takeaways: Juanita refers to the robot as female, always thanks her and says “goodnight”. But ultimately she describes her as an “added ornament to my life”. Critics question the value of interactions with “no mutuality, no real shared experience”. They are concerned that such a companion may reduce human interactions. What sort of future do we want for our elderly?
OpenAI upgrades its natural language AI coder Codex and kicks off private beta
What: OpenAI has launched a significant upgrade to its AI-powered coding assistant, Codex. The system now accepts commands in plain English and outputs live, working code! For example, a games developer may say “make the boulder fall from the sky”. Codex will then drop a boulder from the top of the screen without any prior instruction as to what “the sky” is.
Key Takeaway: Some commentators are heralding a new era of low-code interaction with computers whereas OpenAI itself has identified a range of hazards associated with the technology. These hazards span across "safety, security, and economic factors including producing code misaligned with user intent. Will we find ways to limit the risks while maximising the benefits of this technology?
Twitter's photo-cropping algorithm preferred young, beautiful, and light-skinned faces
What: In March 2021, Twitter phased out its automated system for cropping images in image preview boxes. The previous system worked by presenting the most ‘visually interesting’ area but the concern was that the algorithm demonstrated bias across gender and race in doing so.
Key Takeaway: To the delight and praise of many, Twitter recently ran a public competition with a cash prize to test this hypothesis and the results do indeed demonstrate a number of different biases. For example the algorithm showed preference to light-skinned faces over dark-skinned faces. To resolve this bias for the future, the long-term solution is likely to involve more human involvement in image processing.
The release of ImageNet was a watershed moment in computer vision but is now fingered as a culprit in problems of bias.
New research identifies problematic image collections that continue to be used in research despite being taken offline.
