DeepMind achieves SOTA image recognition with 8.7x faster training
I have a feeling the ML community is going to pivot focus to faster and smaller training before larger advancements are made. It&#x27;s simply too expensive for much AI research to happen when state of the art models take 500k of hardware to train.<p>For all the mathematician hype around ML research, much of the work is closer to alchemy than science. We simply don&#x27;t understand a great deal of why these neural nets work.<p>The people doing math above algebra are few and the scene is dominated by &quot;guess and check&quot; style model tinkering.<p>Many &quot;state of the art models&quot; are simply a bunch of common strategies glued together in a way researchers found worked the best (by trying a bunch of different ones).<p>An average Joe could probably write influential ML papers by gluing RNN&#x2F;GAN layers to existing models and fiddling with the parameters until they beat current state of the art. In fact, in NLP models, this is essentially what has happened with roBERTa, XLNET, ELECTRA, etc. They&#x27;re all somewhat trivial variations on Google&#x27;s BERT, which is more creative but yet again built on existing models.<p>Anyways, my point is, none of this required math or genius or particularly demanding thought. It was basically let&#x27;s tinker with this until we find a way that&#x27;s better, using guess and check. No equations needed.<p>We are a long way from the type of simulations done for protein folding and materials strength and basically every other scientific field. It&#x27;s still the wild west
