Why switch from weld fasteners to clinch fasteners?

According to the experts at Penn-Engineering, engineers usually make the switch from weld fasteners to self-clinching fasteners due to two key motivators: environmental impact and cosmetic appeal. Additional benefits often materialize, though, that have positive effects on time, costs, and end-product quality. Find out how.

Tech Tip: How to create high-quality STL files for 3D prints

Have you ever 3D printed a part that had flat spots or faceted surfaces where smooth curves were supposed to be? You are not alone, and it's not your 3D printer's fault. According to Markforged, the culprit is likely a lack of resolution in the STL file used to create the part.

What is laser peening for metal components?

According to Curtiss-Wright, laser peening (also called laser shock peening) "drives deep plastic strain into a part that creates a high-magnitude residual compressive stress from 1 to 10 mm below the surface." This process involves hitting a part surface with a laser repeatedly through a stream of water, offering designers the ability "to surgically engineer residual compressive stress into key areas of components." Benefits include enhancements to fatigue strength, durability, damage tolerance, and resistance to stress corrosion cracking of critical metallic components.

ChatGPT is smart, but it is no match for the most creative humans

A new study by researchers in Australia has smashed the myth that generative AI systems such as ChatGPT could soon replace society's most creative playwrights, authors, songwriters, artists, and scriptwriters.

The existing large language models (LLMs) have a built-in mathematical ceiling on their creative capacity, meaning they will never rival the originality or ingenuity of the most creative individuals.

That's the finding from creativity expert David Cropley, a professor of Engineering Innovation at the University of South Australia, whose study on the mathematical limits of generative AI has been published in the Journal of Creative Behavior.

Cropley computed the creative ability of LLMs using standard mathematical principles. The results showed that LLM creativity has a maximum of 0.25 on a scale from 0 (no creativity) to 1 (maximum creativity).

"While AI can mimic creative behavior -- quite convincingly at times -- its actual creative capacity is capped at the level of an average human and can never reach professional or expert standards under current design principles," says Cropley.

He says the findings challenge widespread assumptions about AI's creative powers and offer clarity amid a global debate that has often been clouded by hype and misunderstanding.

"Many people think that because ChatGPT can generate stories, poems, or images, that it must be creative. But generating something is not the same as being creative. LLMs are trained on a vast amount of existing content. They respond to prompts based on what they have learned, producing outputs that are expected and unsurprising.

"Unfortunately, many people misunderstand the meaning of creativity. They think it means 'the act of bringing something into being' or 'generating,' when, in fact, it means creating something that is new, original, and effective.

"Creative performance, however, is not symmetrical. Typically, 60% of people are below average when it comes to creativity, so it's inevitable that a sizable slice of society will think that LLMs like ChatGPT are creative, when they're not. Highly creative people will recognise the weaknesses in the generative AI systems."

Cropley's study is the first formal calculation of AI creativity based on the internal mechanics of LLMs.

He says that while AI can be a useful support tool, it cannot replace a highly talented, creative person.

"A skilled writer, artist, or designer can occasionally produce something truly original and effective. An LLM never will. It will always produce something average, and if industries rely too heavily on it, they will end up with formulaic, repetitive work," he says.

"For AI to reach expert-level creativity, it would require new architecture capable of generating ideas not tied to past statistical patterns."

The findings are encouraging for anyone who values human innovation, he says.

"This research shows that the world still needs creative humans -- perhaps more than ever."

The paper is titled "'The Cat Sat on the ... ?' Why Generative AI has Limited Creativity."
