Comment on Integer addition algorithm could reduce energy needs of AI by 95%

technocrit@lemmy.dbzer0.com ⁨2⁩ ⁨months⁩ ago

This is an extremely misleading headline. From the abstract:

… applying the L-Mul operation in tensor processing hardware can potentially reduce 95% energy cost by element-wise floating point tensor multiplications and 80% energy cost of dot products.

In other words… This method of computation could save 95% of the energy spent on floating point multiplication (and 80% of dot products)… Not 95% of total energy.

I’d say it’s not just misleading but incorrect if it says “integer” but it’s actually floats.

Good point. Though, the vast majority of ML training and use is tensor math on floating points, so largely dot and cross products, among other matrix operations.
