Generative AI Doesn't Have a Coherent Understanding of the World, MIT Researchers Find

1 Comment
Long-time Slashdot reader Geoffrey.landis writes: Despite its impressive output, a recent study from MIT suggests generative AI doesn't have a coherent understanding of the world. While the best-performing large language models have surprising capabilities that make it seem like the models are implicitly learning some general truths about the world, that isn't necessarily the case. The recent paper showed that Large Language Models and game-playing AI implicitly model the world, but the models are flawed and incomplete.

An example study showed that a popular type of generative AI model accurately provided turn-by-turn driving directions in New York City, without having formed an accurate internal map of the city. Though the model can still navigate effectively, when the researchers closed some streets and added detours, its performance plummeted. And when they dug deeper, the researchers found that the New York maps the model implicitly generated had many nonexistent streets curving between the grid and connecting far away intersections.

Made this Max Miller originally did the recipe (2018? 2019?) -- I liked it but my partner prefers the custard-style pumpkin pie.

DIY Digital Caliper Measures Up

1 Comment

You might wonder why [Kevin] wanted to build digital calipers when you can buy them for very little these days. But, then again, you are reading Hackaday, so we probably don’t need to explain it.

The motivation, in this case, was to learn to build the same mechanism the commercial ones use for use in precise positioning systems. We were especially happy to see that [Kevin’s] exploration took him to a Hackaday.io project which led to collaboration between him and [Mitko].

The theory behind the mechanism is simple but does get into some ugly-looking trigonometry. Electrically, you feed eight sine waves with different phases into the assembly and measure the phase of the signal you receive.

Pulse density modulation is sufficient for the driving signals. The math is a bit more complex, but nothing you can’t do with a modern CPU. To set the correct parameters, a PC-based test setup allowed different runs to determine the best parameters for the final implementation.

Of course, the whole thing still needs some packaging to use as either a practical pair of calipers or for unrelated positioning duty. But it does work and it should be straightforward to adapt it for any purpose.

We’ve looked inside calipers before. If you are only making measurements with calipers one way, you may be missing out.

I always assumed it was a kind of vernier situation but the ratio of the reflector and emitter pitches is a small integer (8).

Michael Foord: Adventures with MicroPython

1 Share

ZumoBot

My first blog post in a few years! I have some articles Iā€™d like to publish, and some adventures to share, so I thought it was time to fire up a blog engine again.

My nine year old son, Benjamin, is really into programming with Scratch and heā€™s keen to play with electronics and learn MicroPython. Which is awesome because thereā€™s almost nothing I would love to do more with him.

MicroPython is an extremely impressive implementation of Python that will run on embedded devices and microcontrollers, as well as bigger tiny computers like the Raspberry Pi.

Iā€™ve dug out an old MicroBit I had, purchased a Raspberry Pi Pico board/kit and also a ZumoBot 2040 robot which uses the same microcontroller as the Pico, to play with.

Iā€™m now starting to get to grips with the basics, using the Thonny IDE.

I have a bunch of Neopixel LEDs, including a long light strip, Iā€™d like to wire up in my living room controlled by a Pico board and an Android App using Kivy. Thatā€™s my goal number 1.

Iā€™d like to program the ZumoBot to explore and map my flat. Goal 2.

Meanwhile Benjamin is enjoying playing with electronics (switches, LEDs, potentiometer and now a motor) with the Pico and on his own heā€™s programming the MicroBit with Scratch (or at least ā€œblocksā€ which is the Microsoft equivalent). Iā€™ve also done my first soldering in over a decade.

I have a github repository to track my tinkering, but Iā€™d like to write up some recipes and post them on this blog as I go. (The biggest hurdle is I canā€™t easily create circuit diagrams. Time to explore.)

The github repository and ZumoBot links:
