This is an explanation of the Cryptography problem "Not TRUe" from CyLab Security Academy (formerly picoCTF). The difficulty is second from the bottom, with 400 points. Only two files are provided: ...

Vector databases store, index, filter, and search embeddings so applications can retrieve items by similarity at operational ...

Precise shaping and manipulation of intra- and extracavity optical fields is a core objective in optics and photonics. Breakthroughs in modern optoelectronic devices—from camera lenses and microscopes ...

Vector search underpins most retrieval-augmented generation (RAG) pipelines. At scale, it gets expensive. Storing 10 million document embeddings in float32 consumes 31 GB of RAM. For dev teams running ...

You've probably typed a question into a search bar and gotten results that matched your words but completely missed your meaning. Or watched a recommendation engine surface something eerily relevant ...

Penn Engineers have developed a new way to use AI to solve inverse partial differential equations (PDEs), a particularly challenging class of mathematical problems with broad implications for ...

In a groundbreaking advance that promises to revolutionize the field of photonics, researchers have unveiled a novel approach to intracavity light manipulation using full-space inverse-designed ...

If you’ve used ChatGPT, Perplexity, or any modern AI-powered search engine recently, you've experienced vector search even if you didn’t realize it. Unlike traditional keyword-based search, vector ...
