Would you consider this to be doing math the old-fashioned way? Instead of going with silicon-based switching (ie: transistors) this 4-bit adder uses mechanical relays. We like it for its mess of w… ...

In a world’s first, IBM Research announced at this week’s NeurIPS conference an 4-bit AI training system that may help reduce machine learning’s heavy carbon footprint.

4-bit deep learning So what does 4-bit training mean? Well, to start, we have a 4-bit computer, and thus 4 bits of complexity.
