Binary brains for small devices: same smarts, tiny memory

Imagine a neural net that thinks with tiny on/off signals.
Researchers made BinaryNet, a way to train networks where the numbers inside are just binary weights and outputs.
That means most math steps turn into simple bit checks, called XNOR ops, instead of heavy multiplications.
The result uses far less memory, so models fit on small chips and phones, and run much cheaper energy wise.
It still learns to recognize images and patterns well, yet the code and math are much simpler.
On a regular graphics chip the same model ran about 7x faster, with no drop in accuracy.
This opens doors to smart cameras, tiny robots and gadgets that can't carry big chips.
You get good accuracy, lower cost, and speed, all at once.
Try to picture powerful AI that lives in your pocket, not in a giant server, and it works pretty much the same.
Some details are tricky, but the big idea is simple: use ones and minus ones to make AI lean and quick.
