Integral Neural Networks (CVPR 2023 Award Candidate), a nifty way of building resizable networks. My understanding of this work: A forward pass for a (fully-connected) layer of a neural network is just a dot product of the layer input with the layer weights, followed by some activation function. Both the input and the weights are vectors of the same, fixed size. Let's imagine that the discrete values that form these…

Can you point me to papers with reproducible benchmarking that achieves big speedups on those? Modern GPUs are GP -GPUs: where GP means "general purpose" : you can run any code on GPGPUs. But if you want to gain real speed-ups you will have to program in an awkward style ("data parallel"). I am not aware of GPU acceleration of the work-horses of symbolic AI, such as Prolog, or SMT solving. There has been a lot of wor…
I think we're conflating two things: shallow/classic ML is not symbolic AI. I'm not sure "ML" even encompasses anything "symbolic"; I see symbolic AI and ML as subfields with little overlap. I'm not saying symbolic AI has been GPU accelerated in the past, but that non-deep ML has been.
Can you point towards papers that report substantial GPU acceleration on what you call "non-deep ML"?

#75"Overview of SHARD: A System for Highly Available Replicated Data" it's the first paper to introduce the concept of database sharding. It was published in 1988 by the Computer Corporation of America. It is referenced hundreds of times in many classic papers. But, here's the thing. It doesn't exist . Everyone cites Sarin, DeWitt & Rosenb[e|u]rg's paper but none have ever seen it. I've emailed dozens of academics, libr…
1988? As far as anyone can tell, the use of the term "shard" in the context of database replication originated with Ultima Online, which was released in 1997, and which used the term in connection with its underlying mythos (the idea of representing world instances as shards of Mondain's shattered gem). So a documented reference to sharding that's earlier than that would be interesting to see. (Disagree? Instead of d…

Certain bacteria can directly assimilate a mixture of hydrogen, carbon dioxide, and nitrogen to produce protein. You could consider it an alternative to bacterial nitrogen fixation in root nodules with much higher productivity. Or you could consider it an alternative to the Haber-Bosch process with much milder reaction conditions -- ambient temperature and pressure. It's a way to turn intermittent electricity into protein with simple, robust equipment. I wouldn't be surprised if this or a related development ultimately supplants much of the current demand for synthetic nitrogen fertilizers.

How is program synthesis the same as regular expression search? Honest question
Good question. All supervised learning is a form of search with three components: - Specification: what are you are looking for? - Search space: were are you looking? - Search mechanism: how are you going through the search space? Program synthesis is simply learning where the search space is syntax. In deep learning, taking the ImageNet paper as an example, the specification a bunch of photos with annotations, the s…
Here is the full text.
Regexps aren't even Turing complete as far as I know, if whatever they have in their paper works for arbitrary programs it would be shocking. I'll give it a read.
*Edit*: The algorithm in the paper is a DP like algorithm for building regexes. They use a matrix, and it has all the potential strings to be checked on one axis, and all the potential regex programs on the other axis, and in-between values (the actual matrix values) are booleans saying whether the string matches the program. The algorithm builds the matrix iteratively.
I haven't understood how regex evaluation is done, probably directly, but obviously this algorithm is only for checking whether a particular regex program matches an output rather than general purpose synthesis.
We'll have to wait for AI chips to really scale genetic programming, GPUs won't cut it.

The authors show that a biological type laboratory ultracentrifuge can efficiently function as a near-universal isotope separator. Any element that can be dissolved as a salt in water -- the entire periodic table, excepting the noble gases -- can be enriched according to its relative mass. This can reduce the cost of refining certain isotopes like calcium-48 by orders of magnitude compared to the previous best techniques.
Left unsaid, but implied by its universality: the new technique is also a new approach to producing enriched fissile materials for nuclear reactors and weapons. It requires less chemical engineering sophistication than current processes which require production and handling of gaseous uranium hexafluoride.
