You likely mean sampler, not decoder. And no, the stronger the quantization, the more the output token probabilities diverge from the non-quantized model. With a sampler you can't recover any meaningful accuracy. If you force the sampler to select tokens that won't repeat, you're just trading repetitive gibberish for non-repetitive gibberish.
Looks awesome! The YouTube video linked inside the GitHub README seems to be unavailable:

Amazing! The inserted objects are renders of textured 3D models and not generated by a diffusion model + ControlNet? Is there a fixed set of textured 3D models available or are they generated on the fly based on the prompt?
Super interesting! I’m currently writing my master thesis on analyzing relationships between subreddits based on user and semantic similarity. For user similarity I use the Jaccard similarity between the unique set of authors of each subreddit.
Can I send you a message and quote you in my thesis? You can shoot me a short message as well: [email protected]
Still questions that I would assume are semantically similar to the questions you can find in exam prep material all over the internet. My point is that exams are a crutch we use to determine how well a person studied a subject. A crutch we use because we seem to lack better measuring devices. It's very much possible to ace an exam while at the same time being horrible at actually applying/working on a subject. I'd argue therefore that measuring how well LLMs perform on exams designed for humans is simply a more complicated Turing test, with all its shortcomings.
Do you know that the answer key wasn't part of the train set of ChatGPT?
Thanks! Just stumbled across your comment as well.
I recently looked into this as well. Specifically how the two formats differ. As it stands right now the “Feather” file format seems to be a synonym for the Arrow IPC file format or “Arrow files” [0]. There should be basically no overhead while reading into the arrow memory format [1]. Parquet files on the other hand are stored in a different format and therefore occur some overhead while reading into memory but offer more advanced mechanism for on disk encoding and compression [1].
As far as I can tell the main trade-off seems to be around deserialization overhead vs on disk file size. If anyone has more information or experience with the topic I'd love to hear!

That's impressive. The audio track of your videos is so clean and well understandable that I was wondering if you used a studio setup or voice synthesis software. Well done!
Ah, thanks! I didn’t know that and shouldn’t have used the first result that came up with a google search.
Yes, it's easy to see you put a lot of thought into that. I hope your course receives much more exposure. When I first found your videos a few weeks ago, I was surprised how few views they have given to the quality of the course.
Do you record the voice track of your videos yourself?
Glad to see you published the final lesson about transformers. Was looking forward to that!
Seems like the Apple M1 Max is almost half as fast as a RTX 3090. Pretty cool!

I read it as 1/2 cent as in 1 or 2 cent per render.

Austria—Schnitzel not kangaroo.
Why not create a table with a single JSON column and dump everything in there?
Does this work similar to rqlite or dqlite from a usage standpoint, or does it solve a different use case?

Hello HN!Over the last year, I crawled and stored the position of all available bicycles of a large shared mobility provider in Berlin, Germany once a minute (~2.1 billion data points). Subsequently, I calculated 713,562 trip routes as they were likely taken by customers of the provider. The web app linked above provides more background information and visualizes some patterns I find...
Fantastic work! Are the vector tiles compatible with OpenMapTiles styles?
Any best guesses if and when we'll reach the "Kubernetes: The Good Parts" stage? A condensed subset of the currently available features of k8s which would prevent most of the foot guns and make k8s feasible for <20 developer projects.
