Maybe it is not just slacking!

Watching TV with subtitles, instead of with dubbing, improves language skills with statistical significant difference.

In comparison, Bentley has changed its logotype 5 times since 1919, modifying details. "B" has become rounder and feathers are reshaped.

Bentley steadily moves forward, but at a measured pace.

Bentley's new brand logotype is found on the EXP 15 concept car presented yesterday.

It is worth noting that achieving accurate diagnosis does not depend on the competence of the physician alone. Healthcare is a co-produced service. The patients participate to various degrees in providing needed information. I.e. diagnosing in a clinical setting is different from vignette cases.

The accuracy of probability for diagnosis being correct was overestimated in all patient scenarios in a study with 492 physicians. Also after tests had been done. Over-diagnosis likely leads to overuse of medicine. Also, there is a risk of alternative and correct diagnosis never being established.

A study found that physicians were overconfident in their diagnosis accuracy. This might prevent the physician from revising diagnosis. Differential diagnosis overlooked. This could lead to patient harm.

Similarly, generative AI has been shown several times to be overconfident in its results.

Diagnosing is difficult:

A study of 234 physicians accuracy using written patient cases showed 72 % correct diagnosis.

When the physicians were allowed to make three guesses of the correct diagnosis, they were 85 % correct. The corresponding accuracy for a computer algorithm was 51 % correct.

This study compares the performance of physicians with computerized symptom checkers in diagnostic accuracy.

A meta-analysis of multiple studies published 2018-2024 of AI diagnosis showed 52 % accuracy, similar to physicians overall.

Expert physicians were still performing better in diagnosis than AI overall.

How accurate is your physician in setting diagnosis?
Would AI do better?

Microsoft: Physicians had 20 % accuracy and AI had 80% in benchmark w/ complex cases.

Microsoft: physicians do more than diagnose, needed due to ambiguities and trust. AI matures in 5-10y.

Comments has more studies.

A letter written by Catherine de’ Medici, Queen Consort of France, was protected by Letterlocking.

The letter is from c.1570.

Here is a video reproducing how the locking was created, step-by-step.

New tech: Surprising utility of LED screen basketball floor. It is not just about advertising!

"First screen" was in the movie theater. Then followed the screens in TV, PC, phone, pad, and watch. Floor screen to be counted as the 7th screen?

Nice write-up by @bendowsett.bsky.social for @wired.com.
Who Knew Basketball Needed an Interactive LED Floor?

Apple released a paper concluding that current AI models are unable to handle higher complexity tasks. "Complete accuracy collapse" occurs at a threshold of complexity. For both LLM and LRM artificial intelligence. Hurdle to achieving AGI?

At the same time, models are overthinking easy problems.
