• As for other countries, in Russia fluvoxamine is by prescription only, but I guess it’s not controlled very strictly, since it’s easy to visit a few pharmacies until one of them seels it to you even though you say you forgot your prescription list at home.

• So, I don’t know the first thing about American education, so I wonder, can a parent just let their kid stay at home, skip school and do whatever the kid wants while all this crap is happening? If yes, why aren’t they doing it if things are this bad?

• A better type signature would be (List<resource>, List<goal-state>, List<prerequisites>). An even better type signature would be a directed acyclic graph where nodes are skills or knowledge areas, edges are dependencies, parentless nodes are prerequisites, childless nodes are end goals, and each non-prerequisite node has a list of resources associated with it.

• I see you’re frustrated with reactions of LessWrongers. You want to convince us that your model is important. Here are three questions I don’t know the answer to which affect how important I deem your model.

1. How much novelty does it have compared to existing brain inspired machine learning models? Perhaps you can write a “Related Work” section like in academic articles to answer this question.

2. If the answer to the first question is “there is a lot of novelty”, what implications does this have? Why is it important?

3. Are there likely to be practical benefits to using your kind of models instead of neural networks? I.e., are they likely to be faster on inference, cheaper to train, generalize better, or something else, if now research time was put into the study of them?

Apart from this question, I have a recommendation for you. Try to publish your work at a conference or in a journal. If the answer to the first question is at least “as much novelty as there is in a typical brain-inspired model article”, I think your result is publishable given good results on PI-MNIST and PI-FashionMnist. However, it would probably be important to use another dataset that is inherently permutation invariant as a benchmark in order to impress reviewers. This’ll give you prestige, satisfaction, etc. You can also visit a conference about brain-inspired ml or a workshop about brain-inspired ml at a large ml conference, present your work there and take to people. You can also try to find where such people hang out on the internet and take to them there though I expect there’s no such public good place.

• What is BP in BP/​SGD?

So, as I see it, there are three possible different fairness criteria which define what we can compare your model with.

1. Virtually anything goes—convolutions, CNNs, pretraining on imagenet, …

2. Permutation-invariant models are allowed, everything else is disallowed. For instance, MLPs are ok, CNNs are forbidden, tensor decompositions are forbidden, SVMs are ok as long as the transformations used are permutation-invariant. Pre-processing is allowed as long as it’s permutation-invariant.

3. The restriction from the criterion 2 is enabled. Also, the model must be biologically plausible, or, shall we say, similar to the brain. Or maybe similar to how a potential brain of another creature might be? Not sure. This rules out SGD, regularization that uses norm of vectors, etc. are forbidden. Strengthening neuron connections based on something that happens locally is allowed.

Personally, I know basically nothing about the landscape of models satisfying the criterion 3.

Btw, a multilayer perceptron (which is a permutation invariant model) with 230000 parameters and, AFAIK, no data augmentaiton used, can achieve 88.33% accuracy on FashionMNIST.

• I want a way to translate microcovids into expected hours of my life lost, taking into account death, long covid, short term illness and all other effects of covid, if there are any.

• During these 3 months, I’ve gone through one or two packs of 30 lozenges each, not sure. Yeah, I was sick a lot and worried, wondering if I am getting sick or not, even more. I suspect that Life Extension peppermint lozenges hurt my teeth worse than anything else I regularly consume. Perhaps they’re made of sugar? I haven’t checked. As for helping with common cold, I have no idea if they are helping. Maybe, slightly. In the beginning I thought that maybe I am noticing some positive effect, but it could easily be placebo. I also have a hunch that maybe they help with throat symptoms but not with nose symptoms.

• The two plots of the proportion of Omicron among new cases of Covid-19 you posted are from Denmark and the region around Washington. They show that in these locations now or in the next few days approximately half of new cases are Omicron. I am from a country that doesn’t really track statistics of Omicron vs Delta. Is it a good idea to assume that the situation here is approximately the same as in these plots? More specifically, how was the decision to include these plots in this post made? Were these plots included specifically because they look scary or are they more like a truly random sample of locations?

• Solution:

I can do the following to check if the train’s length is a divisor of . Remember the state of the lightbulb in the current carriage, then go carriages forward and check if the state of the light is the same as remembered. If not, the train’s length is not a divisor of . Otherwise, flip the light switch and go backwards carriages, check the light. If it’s the same as remembered, the train’s length is not a divisor of , otherwise it’s a divisor of .

The overall algorithm is, for each from to infinity, perform the above steps and stop as soon as you encounter the first such that the train’s length is a divisor of . This will be the train’s length.

• Somehow I love a lot of songs from a few radiostations of SomaFM radiostations:

• Groove Salad—“A nicely chilled plate of ambient/​downtempo beats and grooves.”

• Illinois Street Lounge—“Classic bachelor pad, playful exotica and vintage music of tomorrow.”

• Christmas Lounge—“Chilled holiday grooves and classic winter lounge tracks. (Kid and Parent safe!)”

• Sure, I understand, no hard feelings.

so if anyone is in this situation, they could still apply for future cohorts.

Do you mean that if one would like to go to such a bootcamp but thinks they won’t be able to get visa in time, they should apply now to get invited to a future cohort? Or should they apply later when you actually announce those future cohorts?

• Being a Russian citizen, if I were to apply for the bootcamp (I am not) and I started applying for a US visa on november 22nd, I would probably not get it in time to attend. Probably, the situation is the same for a large part of the third world. Thus, it would be nice if you announced this earlier and made the application deadline earlier.

• I haven’t had any practice in reading sheet music in like 3 years, and even then I was a novice and was quite slow at it. And I’ve never tried transcribing music in sheet form but I think I can, especially given a tuner, although it’ll take long.

• I am looking for software which will help me learn to sing a song I want to sing. I have extracted its vocal track as an mp3 file. I want to sing it in the same frequencies it’s sung in the vocal track, or perhaps one or two octaves lower. I want a program which will help me do that. I imagine a program would load the mp3 file, then I would tell it that I want to sing one octave lower, and it would, in real time, draw me a graph of the frequencies I am singing together with the frequencies in the mp3 file. I imagine something like this—the frequencies I am supposed to sing in red, my actual frequencies in yellow. Operating systems suitable for me are Linux, Ipad OS, and Android. If instead of loading an mp3 file into the program I’ll have to transcribe the music to sheets myself, that’s worse but perhaps still ok. If you don’t know such a program but know something else I can use to achieve my goal, do tell.

• I have a pretty good competitor—https://​​tableaunoir.github.io. Here’s how they compare:

• Excalidraw—is more polished.

• Tableau Noir—supports LaTeX formulas. It’s weird in that it requires a few additional key presses: (1) make a text field; (2) write a formula enclosed in single dollar signs; (3) with the cursor anywhere in the text field, press enter, then backspace (this step is silly, but otherwise it doesn’t work); (4) press Esc.

• Tableau Noir—has an eraser.

• Tableau Noir—you can insert pages from pdf documents.

• Both—no registration, no bullshit.

• Both—work alright on ipad in the browser, although I have tried both only briefly.

• That would make them more vulnerable to claims that they use organizational mind control on their employees, and at the same time make it more likely that they would actually use it.
