Author here. Yes, it actually does work. If I’m ever indexing fewer than ~100k documents/paragraphs I would use something like this approach rather than reaching for a vector database.
I've been doing research with NLP for about 5 years now I couldn't have created a better inrto list than this. Many of these resources were things I've sent people over the years.
Yeah, this was a little strange. I'm the author of the repo linked here.
I got alerted to it hitting #1 on HN and was able to see it there for only a little bit before it immediately got tanked to # 60. I'm a little bummed, but c'est la vie.
While I don't doubt the statistics brought up in this article, I am skeptical about how the underlying data was sampled. The majority of "homeless" people are not necessarily who everyone is talking about when they think "homeless" (e.g. people dressed in rags sleeping on the streets/doing drugs in public.) I personally suspect that there's quite a difference in that sub-population.
