I added something about materialization while you replied. Materialization is controlled automatic denormalization. I would guess it is usually not labeled as denormalization because the materialized data is not really part of your data mod

Normalized means free[er] of redundancies. If you have a shopping basket, then you need the user it belongs to, the products in it and their quantities. Everything else like shipping costs and total costs can be derived from that. If you ex

I’d argue that all these models are stochastic parrots because they’re not embodied in any way. I do not think that this would really change much in itself. If you tell the model that crimson is a shade of green, it will learn something w

To clarify the 26 m³, that is the gasoline volume with the same energy content as the proposed ship. Tank truck capacities seem to be in the range from 10 m³ for small ones to semi-trailers with 40 m³.

The proposed capacity of 241 MWh is equivalent to a tank truck of gasoline, 26 m³.

For all he knows, the students went to a site with study materials to prep for a test. Generally previous exams are good for checking that you understood a topic but you can not really study a topic only from past multiple choice tests. I

People looking this up online aren't cheating, by definition they are studying. Sure, you could look up previous exams for learning the topic, but you could as well just copy the answers. Given that the answers were [supposedly] obvi

I tried the usual route using getImageData() and am getting between 50 ms for a small region and 100 ms for the full 2048 x 2048 canvas on a 8th generation mobile i5 in Chrome. In Firefox it is 50 ms and 150 ms, all on Windows 10. So the ov

This is however not the same operation, changing the palette will affect all pixel of that color, flood fill affects only all the pixels in the connected component you clicked on.

Most objects (~90-100%) are freed by V’s autofree engine: the compiler inserts necessary free calls automatically during compilation. Remaining small percentage of objects is freed via reference counting. The developer doesn’t need to chan

Humans obviously have the capability to remember so it is hard to imagine what it would be like if we could not. For artificial neural networks it depends on their architecture and use, to be able to get a sense of things changing over time

Sure, an observation itself takes place in time and over a period of time, but a single observation itself does not capture time. Imagine you would see the world through your eyes and immediately forget about it. The process of seeing itsel

Both of us are clearly ingesting time, it is simply another one of our inputs. We are not ingesting time, we are in a certain sense creating it. We constantly observe the world and it changes over time but just observing the world alone i

If you want to not divide by zero, you can just check for zero. You want to use some epsilon if you want to compare floating point numbers, 0.1 + 0.2 == 0.3 for example is false and not what you wanted most of the time. To do this properly

I am not sure what you mean, but sensory inputs can obviously affect you. Hearing a bear roar right behind you will probably change you state of mind pretty quickly.

However, anyone who has done respectable doses of psychedelics probably agrees with me that there’s a bit more to dreams, NDE and afterlife than “random” neurological firings. Why would that be the case? If anything, it seems to me, takin

Another problem with lockless is that you can't turn every algorithm into a lockless one, it's actually only a handful of them that are practical to implement locklessly. You can make every data structure lock-free, even wait-fr

It is more than that, it is essentially the entire clock containing the primary oscillator and dividers respectively counters. Watch closely, when several digits change at once, then it emits multiple pulses. Also note that the pulses are e

Say m contains the prime factor p^i and n contains the prime factor p^j, then m^n will contain p^in and n^m will contain p^jm. For them to be equal we need in = jm or i/j = m/n but for a given solution m/n is constant and the

Rotations of a point happen in a plane around some point in the plane, not around a line or axis. In two dimensions there is no line perpendicular to the plane to rotate around, in four and higher dimensions there is no unique plane perpend

I case somebody else wonders, here [1] are some electron microscope pictures of neurons [and other stuff] to better understand what 5 µm voxels means. Seems about one order of magnitude away from being able to image all the connections. [1]

This is how I imagine the human brain works. In principle we think iteratively, do one small computation, memorize the result, then do the next step based on the input and the result from the previous step. If things get too complicated, we

I find that comparison quite interesting with respect to the energy intensity of producing lithium ion batteries. A factory that can produce two oil barrels per hour or seven 60 liter gasoline tanks per hour or will also produce 35 GWh stor

Technically speaking you can not get rid of the anode unless you also get rid of the cathode as anode and cathode switch places between charging and discharging. It is just by convention that in case of batteries the role while discharging

5 GWh in what time? Gigafactory 1 was at 30 GWh per year in 2019 and they planned to ramp up to 54 GWh, according to Wikipedia. So probably per year? Which would make their production capacity 570 kW. Also according to Wikipedia, a producti

If I understand this correctly as I mostly read this just today, then Cook reductions - which is the name for polynomial Turing reductions - are the more general class whereas Karp reductions - which are polynomial many-one reductions - are

What in the response indicates Turing or Cook reductions? I would say the answer does not go into nearly enough technical details to conclude anything like that, it does not even mention [polynomial time] reductions. Even among the people s

I meant you are confusing whether such scripts can be blocked and whether it would be effective to do so. That it can not be blocked would require some fundamental or practical obstruction like having to solve the halting problem or whatnot

This is confusing whether it can be blocked and whether it would be effective. Every time you do something unique, you of course become identifiable. But the idea is of course that you are not the only one blocking these scripts which will
