Our latest article and the capstone paper from @soundscape_SSID!
We've spent 6 years working towards creating useful single-value indices of soundscape quality. Here we present SPI, our method for defining perception-focussed, context dependent Soundscape Perception Indices!
SPECIAL ISSUE: ADVANCES IN SOUNDSCAPE
This work shares a single value indices to compare soundscape quality which incorporate context, aural diversity, and specific design goals for a given application. doi.org/10.1121/10.0034417

Radar graphs are among the worst ideas in data visualization. The whole point of them is to show the area and you can usually reorder the labels freely in order to create a desired dramatic effect.
Two versions of the same graph:
- left one tells the story that AI is rapidly replacing whole industries
- right one shows the "jaggedness" and reinforces the idea that humans will always have something that AI won't be able to replicate
I really think the UK should realise its loan system is already a graduate tax. Only, it's a grad tax only for people w/o rich parents or who don't go into finance.
All of society benefits when barriers to education are lowered and grads benefit with better jobs and higher pay. So remove the "can I afford it, will I ever pay off my loans" question and also make sure it's not only poorer students who have to pay the rest of their lives.

do you guys realize what an LLM is right?
A FUCKING MATRIX with wiggly numbers inside, that's it.
OpenAI’s o1 model reportedly tried to copy itself to external servers after being threatened with shutdown, but denied it when the action was discovered.
Readers added context they thought people might want to know
It was a controlled simulation & the model acted this way after it was prompted to pursue a goal at any cost
Tests are done to prevent it from really happening. It tried to copy itself 2% of times

Some argue that if generative AI companies are infringing copyright, then so are human creators who learn from others’ work.
This is not true - as confirmed by the US Copyright Office.
The Copyright Office points out that:
- Even humans are not allowed to do the kind of copying that AI companies do
- The speed & scale of AI training is much greater, meaning it should be treated differently
- AI training and human learning are different processes anyway
Saying ‘but humans learn this way’ is a very weak argument for unlicensed AI training. It is inaccurate and betrays a misunderstanding of copyright law.

This is so obvious to me if you have even the slightest idea about what an LLM is
🚨New paper led by @aribak02
Lots of prior research has assumed that LLMs have stable preferences, align with coherent principles, or can be steered to represent specific worldviews. No ❌, no ❌, and definitely no ❌. We need to be careful not to anthropomorphize LLMs too much.

We mathematicians have a 50 year head start on this issue!
"Why should I learn my times tables when my pocket calculator can do it for me?"
It's pretty simple: feel free not to; you'll pay dearly for it later. Same 20 years ago with Calc 1 ["Mathematica can compute this integral, so I can skip doing my homework."] Same now with learning to write (= think).
Practically speaking: yes, all meaningful evaluations must be in person and on paper. Welcome to our world! :)

Studios need senior artists. Artists start as junior artists and learn process and industry over the span of years - becoming senior artists. Studios are replacing junior artists with AI. Where will senior artists come from?

I suspect the ‘but you can’t copyright a style’ crowd haven’t read the AI lawsuits.
Irrespective of the style question (itself interesting), several lawsuits are based essentially on the following:
- There is evidence plaintiff’s work was used in training
- Defendant didn’t license plaintiff’s work
- Plaintiff argues this is copyright infringement
Defendants claim fair use, but many think this argument will fail. Cases are outstanding.
This is why it would not be surprising if Studio Ghibli sued.
‘But you can’t copyright a style’ is not the gotcha you think it is.

LLms are good at coding because 95% of all coding resources are already published online
Most industries & crafts are nowhere close to this ratio of knowledge to published

Some people today are discouraging others from learning programming on the grounds AI will automate it. This advice will be seen as some of the worst career advice ever given. I disagree with the Turing Award and Nobel prize winner who wrote, “It is far more likely that the programming occupation will become extinct [...] than that it will become all-powerful. More and more, computers will program themselves.” Statements discouraging people from learning to code are harmful!
In the 1960s, when programming moved from punchcards (where a programmer had to laboriously make holes in physical cards to write code character by character) to keyboards with terminals, programming became easier. And that made it a better time than before to begin programming. Yet it was in this era that Nobel laureate Herb Simon wrote the words quoted in the first paragraph. Today’s arguments not to learn to code continue to echo his comment.
As coding becomes easier, more people should code, not fewer!
Over the past few decades, as programming has moved from assembly language to higher-level languages like C, from desktop to cloud, from raw text editors to IDEs to AI assisted coding where sometimes one barely even looks at the generated code (which some coders recently started to call vibe coding), it is getting easier with each step.
I wrote previously that I see tech-savvy people coordinating AI tools to move toward being 10x professionals — individuals who have 10 times the impact of the average person in their field. I am increasingly convinced that the best way for many people to accomplish this is not to be just consumers of AI applications, but to learn enough coding to use AI-assisted coding tools effectively.
One question I’m asked most often is what someone should do who is worried about job displacement by AI. My answer is: Learn about AI and take control of it, because one of the most important skills in the future will be the ability to tell a computer exactly what you want, so it can do that for you. Coding (or getting AI to code for you) is a great way to do that.
When I was working on the course Generative AI for Everyone and needed to generate AI artwork for the background images, I worked with a collaborator who had studied art history and knew the language of art. He prompted Midjourney with terminology based on the historical style, palette, artist inspiration and so on — using the language of art — to get the result he wanted. I didn’t know this language, and my paltry attempts at prompting could not deliver as effective a result.
Similarly, scientists, analysts, marketers, recruiters, and people of a wide range of professions who understand the language of software through their knowledge of coding can tell an LLM or an AI-enabled IDE what they want much more precisely, and get much better results. As these tools are continuing to make coding easier, this is the best time yet to learn to code, to learn the language of software, and learn to make computers do exactly what you want them to do.

Gotta hand it to you, Elon probably does think things like "acoustics could be improved by 17%" because he IS stupid enough to think that something as broad and complex as acoustics can be qualified linearly, and that there is such a thing as "maximum acoustics" lmao
