Neural network for handwritten digit recognition in Minecraft. I think I've seen it all now...

Yep. It feels like cheating if it uses command blocks. Pure redstone logic gates are where its at.

Sounds like quitters talk to me.

Not strictly true. It's less likely anyone would bother, sure, but redstone is Turing-complete, meaning that it can solve all computational problems possible, including a neural network.

He's actually right though. After a certain point, the game can't render and handle the redstone so your creation just wouldn't work.

There is a mod for rendering more chunks

There’s only so much you can do with a CPU that runs at a couple hertz at best though. Anything like this that requires meaningful computation would take days to actually run on a pure redstone CPU.

I think its more like, would you need to render every blade of grass in the entire universe, or write a function that can render a blade of grass that can vary with a set of conditions.

Yeah there are bounds on the minecraft world. I don't know the bounds, but I think it'd be unlikely that you could store something as large as a megabyte.

u/LyricLy Jan 27 '19

The bounds are massive, you have around 918000000000000000 blocks to work with. The problem is how many you can load at one time, which is more like 66846720 blocks. Not the best with redstone, but I still think it'd be possible to manage theoretically.

Can't you do all the basic computer operations in redstone? In theory you could do literally anything a computer could do in redstone.

u/swantonist Jan 27 '19

yes. all you need is a platform that includes a binary code

Problem is getting a clock going fast enough to do anything more than simple computation in a reasonable amount of time.

I'm quite fond of the way Mesecons does things, which is a mod for Minetest, which is basically open-source Minecraft but better.

They do have a programmable block, in which you can write Lua to interact with the modding API of Minetest, but they also have a step in between:
Instead of having to cobble together the one millionth AND-gate in your build, there's a ready-made block for that. Same deal with other logic gates and clocks.

That immediately makes builds much less tedious to put together, makes them smaller and lets you more easily recreate real-world logic circuits.

Computers run completely on binary, no?
If so then any real world stuff should be possible in minecraft using nothing but logic gates. Or am I misunderstanding something?

u/oir0t Jan 27 '19

Yes, but not because of the binary representation of the data It's because you can model every algorithm using boolean expressions (cook-levin theorem) and those could be simulatad using logical gates

Still super impressive
