With much excitement and after a 3 year hiatus, I share my latest blog post "A New algorithm on multi-armed bandits".
extremelearning.com.au/multi…
This topic that falls under the broad umbrella of #ReinforcementLearning and played a key role in the AlphaGo algorithm.

I've proven the strangest result of my career..
The classic idea that gradient descent's rate is best with constant stepsizes 1/L is wrong. The idea that we need stepsizes in (0,2/L) for convergence is wrong.
Periodic long steps are better, provably.

It wasn't until I'd *taught* algorithms a few times that I finally understood why sorting is in the CS curriculum. Unfortunately, most curricula don't explain this!
It is NOT because sorting is an important algorithm to learn to implement...

As a 41 year-old software developer do you know how many times I've had to manually implement QuickSort?
Zero.
Maybe we should test for more useful skills like taking a slow SQL query and optimizing it.

I love the Samsung Frame TV but got really tired of paying a subscription for the art—so I made a little script that lets you use a folder of your own images to rotate randomly on your TV. 👀github.com/ow/samsung-frame-…

Yeah and I thought it was really pushy and self-centred when I first saw it. But then I realised that everyone’s feed is so full and stuff disappears down within hours, that reposting useful things across the weekend at different times can actually be very helpful to readers.

If you read a paper and you think, “man, this is a good paper” it costs you nothing to email the author and let them know that you appreciate their work. Compliments are rare in #academia but they needn’t be.

When people say mucormycosis has a high mortality rate, it is often mortality at 3 months! That's where the numbers like 50-70% come from. So, you can't calculate mortality at 10 days post onset of symptoms, or not follow up cases, and claim it is low.
