lukasb··on Ketamine's effect on depression may hinge on hope
The way I would rephrase OP is "what is the most useful abstraction for the mechanism of action of these drugs". It might be that limiting yourself to neurological phenomena gives you a much longer, more unwieldy model of what's happening here than an equally predictive model that centers on subjective experience.
lukasb··on Fair coins tend to land on the same side they started
Even simpler - you pick, knowing nothing, so there's a 2/3 chance you're wrong.

If you're wrong, Monty points to toward the right door.

So you should switch.

lukasb··on ChatGPT can now search the web in real time
edit: enable in settings, log out+in, mouse over "GPT-4" at the top

Hm, is this available in the web app?

lukasb··on Show HN: Symphony – Use GPT-4 to call functions in sequence
How would this work? Say I need multiple function calls to handle a user prompt. OpenAI will only supply one function call at a time. My understanding is that "auto" just lets it choose which function to call, but you still have to know that you need to call it multiple times, and when to stop.
lukasb··on Show HN: Symphony – Use GPT-4 to call functions in sequence
Well, this knows when to stop calling GPT-4, which seems non-trivial.
lukasb··on Guidance: A guidance language for controlling large language models
Can anyone comment on how well this does at coercing json output vs OpenAI function calling?
lukasb··on iPhone 15 and iPhone 15 Plus
Why is it foolish? Are drivers really well hardened now?
lukasb··on Evidence for Hipparchus’ Star Catalogue revealed by multispectral imaging (2022)
Worth the click just for the three image sequence showing the effectivess of multispectral imaging.
lukasb··on Spinoza: Life and Legacy
I'm surprised dual aspect theory as a solution to the mind-body problem isn't better known (at least, I hasn't heard of it.)
lukasb··on Reading Ancient Scrolls
Glad to see progress on this, hoping we find out just how badly Plato slandered the sophists.

A lot of the images aren't loading for me in the post, though.

lukasb··on Automatic music playlist generation via simulation-based reinforcement learning
What financial reasons?
lukasb··on Not paying electricity for an entire year with Tesla Solar Roof [video]
People talk about how the grid wouldn't be able to handle everyone switching to electric cars. I wonder how residential solar (which works better in some places than others obviously) fits into that.
lukasb··on WW2 Meteorology
Had no idea it was that easy to run arbitrary JavaScript on a mobile web browser. Thanks.
lukasb··on The Free Movie
Just get multiple versions, discard outliers per frame, and average.
lukasb··on Emerging architectures for LLM applications
That doesn't seem like the type of problem that can be solved with a drop-in solution.
lukasb··on SnapFusion: Text-to-Image Diffusion Model on Mobile Devices Within Two Seconds
What newer schedulers?
lukasb··on Thunderbird Is Thriving: Our 2022 Financial Report
Looked at the staff list for a product manager, or a UX designer ... eventually found "product and business development manager" (and "product design manager" and almost everyone else is an engineer. I'm guessing the product and design people are super overstretched and don't have a lot of sway. So that would explain why the UX is what it is.
lukasb··on Change my mind: Density increases local but decreases global prices
But Tokyo has accommodated growth without rent increasing significantly. No US city can say the same (edit: zip1234 proves me wrong below.)
lukasb··on Why Perl?
perfect
lukasb··on Prompt injection: what’s the worst that can happen?
Actually I think the impossibility of using natural language instructions to LLMs to prevent prompt injection demonstrates (or will demonstrate) that no true understanding is happening.
lukasb··on Large Language Models Are Human-Level Prompt Engineers
So base model+RLLLMF performs as well as base model+RLHF. That could mean a lot of things - it could mean the base model puts a ceiling on the total possible accuracy, so having human-level performance at the RL step doesn't matter as much. And looking at the scores on the individual tests that make up the composite accuracy metric, that looks probable.
lukasb··on Large Language Models Are Human-Level Prompt Engineers
What is the accuracy of the resulting model? Over what range of inputs?
lukasb··on Large Language Models Are Human-Level Prompt Engineers
I see people saying things like this but I have yet to see anyone show data for a non-trivial workflow with human-level accuracy over a wide range of inputs, without a human in the loop.
lukasb··on A trick to reaching flow: Leave your work broken
So yeah, good news about that ...
lukasb··on OpenAI Tokenizer
Could the properties of the distribution (the spread? not stats literate enough) be used to calculate a confidence metric for the answer?
lukasb··on The layoffs will continue until (investor) morale improves
Well, Elon Musk just sent Twitter employees an email saying it's worth about $20B. He paid $44B for it.

lukasb··on I Returned the Mac Mini M2 Pro
I wonder if he was using a Bluetooth keyboard. I've had to restart the Bluetooth module on my M1 a few times to stop this from happening.
lukasb··on Something Pretty Right: The History and Legacy of Visual Basic
So? Why HASN'T anyone built Visual Basic for the web?
lukasb··on Show HN: GPT Repo Loader – load entire code repos into GPT prompts
I've been wondering if you could use something like llama-chain's tree summarization, but modified to be aware of inter-module dependencies: https://gpt-index.readthedocs.io/en/latest/guides/index_guid...

This would be a LOT of fun on salt flats
