Playing around with Mastodon

I created a profile on Mastodon in 2019, but haven’t done anything with it. I’d check in every now and again to see how the platform was developing and, while I was always intrigued with the notion of an open source microblogging ecosystem, it never really captured my attention. So for a while now, it’s…
AI is already an important part of clinical practice. Just not in the way that you think.

We’re all using AI all the time. We just don’t always recognise it. There’s a lot of discussion around the introduction of AI-based systems into clinical practice and healthcare systems. But these discussions tend to focus on the systems that are being designed, developed, and deployed as part of formal processes centred on ‘big ideas’…

This digest has an AI and machine learning focus because I’m preparing a presentation for the SAAHE conference next week, and my topic is Clinicians’ perceptions of the introduction of AI into clinical practice. It’s from an international survey I completed in 2019, mostly forgot about in 2020 (because, Covid) and am finally trying to…

The researchers tested it against dozens of bacterial strains isolated from patients and grown in lab dishes, and found that it was able to kill many that are resistant to treatment, including Clostridium difficile, Acinetobacter baumannii, and Mycobacterium tuberculosis. Trafton, A. (2020). Artificial intelligence yields new antibiotic. Big Think. Something that stood out for me…

…the only really useful value of artificial intelligence in chest radiography is, at best, to provide triage support — tell us what is normal and what is not, and highlight where it could possibly be abnormal. Just don’t try and claim that AI can definitively tell us what the abnormality is, because it can’t do so any…
When AI Misjudgment Is Not an Accident

The conversation about unconscious bias in artificial intelligence often focuses on algorithms that unintentionally cause disproportionate harm to entire swaths of society…But the problem could run much deeper than that. Society should be on guard for another twist: the possibility that nefarious actors could seek to attack artificial intelligence systems by deliberately introducing bias into…
AI Can Now Identify Racist Code Words on Social Media

“We essentially gathered hateful tweets and used language processing to find the other terms that were associated with such messages… We learned these terms and used them as the bridge to new terms—as long as we have those words, we have a link to anything they can come up with.” This defeats attempts to conceal…
DeepMind’s AI can detect over 50 eye diseases as accurately as a doctor.

This is the point at which the risk from medical AI becomes much greater. Our inability to explain exactly how AI systems reach certain decisions is well-documented. And, as we’ve seen with self-driving car crashes, when humans take our hands off the wheel, there’s always a chance that a computer will make a fatal error…
