Badly formatted paper with handwavey abstract with no real focus and dropping buzzwords aplenty... I'll pass...

Oh - it's written by Jeff Dean, inventor of Mapreduce, Bigtable, tensorflow, and practically a god... Yeah, I'll read it!

Read it. Worth a read, especially for those not closely following the machine learning world.

The last section, focussing on having a single large sparsely activated model which can accomplish thousands of different tasks by using a selection of internal 'experts' interests me the most.

I suspect this type of model isn't used much today simply because each company using ML only typically has a few problems to solve. If someone like Google, with far more different problems to solve, can get this type of model to work and demonstrate its effectiveness, I think it would be a big step towards solving artificial general intelligence.

Jeff Dean has a lot of respect and influence inside Google, and his ideas tend to get implemented. I'm looking forward to it!

brain floating point ... cool name

i guess brain's synaptic precision could go way lower, as low as 26 distinct synapse weights: https://elifesciences.org/articles/10778

> A particularly interesting research direction puts these three trends together, with a system running on large-scale ML accelerator hardware, with a goal of being able to train a model that can perform thousands or millions of tasks in a single model. Such a model might be made up of many different components of different structures,

yup, he is building a brain

Sparsely activated multitask model is a kind of Jeff Dean's hobby horse. It was published in 2017: https://arxiv.org/abs/1701.06538. My assessment is that it is an intriguing but ultimately failed experiment, like Geoffrey Hinton's capsule network.

Thanks for the link. Artificial neural networks all the way down to binary weights [1] although this approach doesn't seem like the most efficient one. It's interesting how we're still seeing a ton of variability in ML architectures: it suggests we haven't stumbled on the right area yet. It reminds me how early aviation had a huge diversity of aircraft plans, but now, after a lot of optimization, we've settled on that one standard airliner shape everyone uses everywhere.

Does anyone happen to have a link to a paper or book describing the state of the art in placement and routing algorithms? I'd like to read up on that topic.

These two books might be useful,

1) https://www.oreilly.com/library/view/electronic-design-autom... 2) https://www.crcpress.com/Electronic-Design-Automation-for-IC...

On the first book, see chapter 10 - 12 (on floorplanning, placement, and routing). End of chapter 11 points you to some literature survey as well. But the book itself is somewhat dated (published in 2009)

I haven't read the second book but it's much more recent (published in 2018), it also has chapters on placement, and routing.

Plus applying ML to improving the underlying hardware and software. On the other hand it's not recursive yet and moore's law ending throws a wrench into exponential self-improvement, but it's still a little concerning.
