Hacker News with Generative AI: Embeddings

Harnessing the Universal Geometry of Embeddings (arxiv.org)
We introduce the first method for translating text embeddings from one vector space to another without any paired data, encoders, or predefined sets of matches.

Embeddings are underrated (2024) (technicalwriting.dev)
Machine learning (ML) has the potential to advance the state of the art in technical writing. No, I’m not talking about text generation models like Claude, Gemini, LLaMa, GPT, etc. The ML technology that might end up having the biggest impact on technical writing is embeddings.

Launch HN: Exa (YC S21) – The web as a database (ycombinator.com)
Hey HN! We’re Will and Jeff from Exa (https://exa.ai). We recently launched Exa Websets, an embeddings-powered search engine designed to return exactly what you’re asking for. You can get precise results for complex queries like “all startups working on open-source developer tools based in SF, founded 2021-2025”.

Sharding Pgvector (pgdog.dev)
If you find yourself working with embeddings, you’ve shopped around for a vector database. pgvector is a great option if you’re using Postgres already. Once you reach a certain scale (about a million arrays), building indices starts taking a long time. Some workarounds, like parallel workers, help, but you still need to fit the whole graph in memory.

How to Implement a Cosine Similarity Function in TypeScript (alexop.dev)
To understand how an AI can understand that the word “cat” is similar to “kitten,” you must realize cosine similarity. In short, with the help of embeddings, we can represent words as vectors in a high-dimensional space. If the word “cat” is represented as a vector [1, 0, 0], the word “kitten” would be represented as [1, 0, 1]. Now, we can use cosine similarity to measure the similarity between the two vectors.

Interpreting Clip with Sparse Linear Concept Embeddings (SpLiCE) (arxiv.org)
CLIP embeddings have demonstrated remarkable performance across a wide range of computer vision tasks. However, these high-dimensional, dense vector representations are not easily interpretable, restricting their usefulness in downstream applications that require transparency.
