Artificial intelligence research has a slop problem, academics say: ‘It’s a mess’ AI research in question as author claims to have written over 100 papers on AI that one expert calls a ‘disaster’

This article from The Guardian discusses many of my own concerns about AI right now:

I asked a few people that question at SC25….the ones standing underneath banners saying ‘AI factory blah blah’

I still don’t know!

OK, this turned out to be a totally unexpected and really cool restoration technique. Physicists! MATLAB! Transfer film! Laser cutter!

If you’re in St Louis for #SC25 I highly recommend going up the arch. Here’s one of the views from the top where you can also see its shadow

I'm from MathWorks. Yes, this is normal and expected. When I teach my High Performance Computing in MATLAB courses, its one of the things I mention : don't co 'clear all'

It is because of JIT compilation, function caching and so on. I'll see if I can find a reference. If not, I'll write one.

MathWorks release MATLAB MCP Core server

In the video below you are watching Claude read a file on my local machine and use my local install of MATLAB to analyze it. Claude writes the MATLAB code,puts it on my machine and runs it using my copy of MATLAB

Unless AI is kept in check, it will not only eat its own homework but it will also eat its legibility. We will lose the skill to distinguish a composition of a type of work, a deliberate work, against a hybrid work, a piece of work, an argument, fabricated out of past fragments. Audiences will be conditioned to believe that good enough is good enough, until even mediocrity will seem like plenty. Culture will be turned into monocropped and deprived of nutrients. The creative commons will be exhausted. And as is soil when it is overfarmed, once lost, it will not be easily recovered.

Let us not flatter ourselves. It is not that AI will soon surpass us in thinking, it is more likely that it will surpass us in boring. When we leave machines to eat their own homework we are not training a generation of geniuses but beige. The cry is straight: do not confuse abundance with richness, fluency with thought, content with creation. Surprise still matters. Originality is not luxury but lifeline. Unless we defend it, we will drown in competence without creation.

We also support and ship solvers from SUNDIALS blogs.mathworks.com/matlab/2024/...

Which of those 50 solvers are useful to you and why?

Noting that they are using MATLAB 2019a there. I'm not sure how it would affect those benchmark results but there has been a lot of work done on what MATLAB can do with ODEs since then.

Do this

I feel these vibes very strongly. I use LLMs all the time and understand them in much more detail than most of the people who insist I should use them more!

When I point out weaknesses of the tech, I get accused of being an anti tech luddite who doesn’t get it.

I got a garmin fenix 8. In many ways it’s inferior to the Apple Watch. In some ways it’s vastly superior though, battery life being one of them. The garmin lasts weeks, not hours. Game changing!

I originally paired my iPhone with an Apple Watch. It was seamless, beautiful, functional…in loved it!

Battery sucked though. I wasn’t even sorry when this happened, it gave me an excuse to ditch it.

In the real world, battery life on a phone is extremely important. When I first got my iPhone pro max 13, the battery life was truly stellar and it remains pretty good even now.

I couldn’t give a wossname about thinness. Make it thick and make the battery last a week!!!!!

I held a Samsung Galaxy Z Fold 7 recently and it was the first time in years that I had genuine gadget lust. I really wanted it!

I moved from android to iPhone a few years ago solely for improved battery life but this almost made me go back….almost.

In a discussion with publishers this morning, we were reminded of this Springer Nature data showing that 19% - 66% of paper authors develop new software as part of their research, where the 19% is more or less for all fields, and the 66% is for computational science.
