Sure; total blinding is an issue with many drugs (however active placebos which can make you feel dizzy/sedated/whatever can help); opiods/fentanyl/etc sometimes have to make do with imperfect blinding. The fact remains

There are a number of problems with these statements, but a major one is that psychedelics are associated with reduced activity within the DMN (but increased activity between the DMN and other networks). It is not clear the direction in w

I agree that there's plenty of footguns with async python, but I think the hype is a bit overblown. A few sensible defaults in the standard library would go a long way, e.g. requiring a maxsize argument to Queue (or None if you really

Sure. We can't prove that other organisms experience qualia; we can only look at the effects of qualia (e.g. behaviors that are likely to be the product of emotions) and assume that an organism is therefore conscious. The real point,

Isn't Maturana's theory that consciousness has to do with language, and the use of language to make distinctions about ourselves and others? To me, this seems clearly insufficient to explain consciousness - qualia totally precede

What a wild take. The straightforward takeaway from the end of ZIRP and the resulting increase in focus would be that you need to say no to more things, not fewer? You have to really contort yourself to argue that actually ZIRP gave rise

I don't think we should undersell that transformers and semantic search are really powerful information retrieval tools, and they are extremely potent for solving search problems. That being said, I think I agree with you that RAG is f

I'd argue the author missed a trick here by using a fancy embedding model without any re-ranking. One of the benefits of a re-ranker (or even a series of re-rankers!) is that you can embed your documents using a really small and cheap

For technical domains, stuffing the context full of related-and-irrelevant or possibly-conflicting information will lead to poor results. The examples of long-context retrieval like finding a fact in a book really aren't representative

Yes; you can phone it in post-tenure. But just because it is possible doesn't mean (in my experience) it is common; and I don't think it's helpful (as TFA claims) to equate this possibility with "a total scam." To g

Worth noting that the filtering implementation is quite restrictive if you want to avoid post-filtering: filters must be expressible as discrete smallints (ruling out continuous variables like timestamps or high cardinality filters like ids

I don't really understand the point around error handling. Sure, with structured outputs you need to be explicit about what errors you're handling and how you're handling them. But if you ask the model to return pure text, yo

In my experience the semantic/lexical search problem is better understood as a precision/recall tradeoff. Lexical search (along with boolean operators, exact phrase matching, etc.) has very high precision at the expense of lower r

Doesn't this depend on your data to a large extent? In a very dense graph "far" results (in terms of the effort spent searching) that match the filters might actually be quite similar?

I couldn't agree with this more. I don't think the majority of problems with vector search at scale are vector search problems (although filtering + ANN is definitely interesting), they're search-problems-at-scale problems.
