cpdomina··on RAG Is Simpler Than You Think
what I implied is that in 2024 a lot was written about RAG, LLMs were trained on it, and that explains your gpt-4o-mini reference. the argument is that the article is ai slop, and that point is totally unrelated to name dropping fortune 500s references
cpdomina··on RAG Is Simpler Than You Think
the biggest giveway is actually not the writing style, but the content

"using GPT-4o-mini for query rewriting" -> model from 2024, when RAG was trendy, and all the langchain, llama-index, etc, docs mentioned this specific model

cpdomina··on Algorithms on billion-scale graph using 10GB RAM: I love DataFusion
cool! you might be interested in graphchi (2012), also designed to do large scale graph operations on a single machine

cpdomina··on Open source AI must win
there was a project trying to achieve some of those goals a few years ago using p2p: petals https://github.com/bigscience-workshop/petals

their bloom model was also a collaborative effort https://huggingface.co/docs/transformers/en/model_doc/bloom

cpdomina··on Project Vend: Phase Two
AI agents are still a pretty big topic in crypto, a lot of projects doing what you described. did you try https://github.com/ccxt/ccxt
cpdomina··on The semantic web is now widely adopted
Semantic Web is now revived into its new marketing incarnation, called Knowledge Graphs. There's actually a lot of work on building KGs with LLMs, specially in the RAG space e.g., Microsoft's GraphRag and llama_index's KnowledgeGraphIndex
cpdomina··on AudioFlux: A C/C++ library for audio and music analysis
For MIDI:

https://github.com/Music-and-Culture-Technology-Lab/omnizart and https://basicpitch.spotify.com/

They work better if you apply some source separation before (e.g, https://github.com/sigsep/open-unmix-pytorch, https://github.com/facebookresearch/demucs, or https://mvsep.com)

Still, I think the best results are from proprietary models (specifically https://www.ableton.com/en/manual/converting-audio-to-midi/ and https://www.celemony.com/en/melodyne/what-is-melodyne)

cpdomina··on NanoGPT
To train small gpt-like models, there's also aitextgen: https://github.com/minimaxir/aitextgen
cpdomina··on OpenAI ChatGPT: Optimizing language models for dialogue
You can call any of the huggingface models [1] using their API [2]. A few examples:

- https://huggingface.co/EleutherAI/gpt-j-6B

- https://huggingface.co/t5-base

- https://huggingface.co/facebook/opt-66b

- https://huggingface.co/bigscience/bloomz-3b

There are also other companies offering large models as a service:

- https://www.forefront.ai

- https://nlpcloud.com

- https://www.goose.ai

- https://cohere.ai/generate

cpdomina··on The Twitter Ranking Algorithm
Indeed. He managed to disrupt another industry, this time the fabric of space and time! What a time to be alive.
cpdomina··on Show HN: Get the guitar chords from your Spotify playlists
Ableton Live has a Audio to Midi [1] feature that works pretty well to extract notes from audio. Melodyne [2] is a very powerful tool to mess around with notes in general.

There's also some open source projects out there, such as aubio [3] and Omnizart [4].

cpdomina··on Ask HN: Why there are no Android mini phones?
The screws have a very easy direct access, I can see them being repurposed for other means with a bit of effort.
cpdomina··on Ask HN: Why there are no Android mini phones?
The keyboard is a little small, and does take a bit to get used. Not recommended for big fingers.

Battery life is pretty good; I charge it at night, and usually is half-battery. My usage is pretty decent, but mostly on wifi.

cpdomina··on Ask HN: Why there are no Android mini phones?
Just noticed they have a new version with android 10: https://cubot.net/Smartphones/KingKong-mini-2
cpdomina··on Ask HN: Why there are no Android mini phones?
I have been using a Cubot Mini (4") for sometime now (1+ year), and am pretty happy with the experience overall. Feels so good to have a phone that fits in any pocket.

cpdomina··on KELM: Integrating Knowledge Graphs with Language Model Pre-Training Corpora
The field of Open Information Extraction has been trying to do that in a generic way for a long time, but the results are still far from good. A few references: OpenIE [1] Graphene [2] MinIE [3].

If you already have a Knowledge Graph (KG) and want to populate its instances from documents, that's called KG Population, and Knowledge-net [4] is a good reference.

Relation Extraction is another interesting approach if you know which kind of relations you're interested in, OpenNRE [5] a good example.

cpdomina··on Nonnegative matrix factorization
NMF works great for unsupervised audio source separation, e.g. [1]. See [2][3] for a good overview of the field.
