http://i-programmer.info/news/202-number-crunching/11263-open-source-sparse-tensor-computation-is-fast.html
http://i-programmer.info/news/202-number-crunching/11263-open-source-sparse-tensor-computation-is-fast.htmlTensors are data tables in n dimensions and when they occur they are often sparse, i.e. most of the entries are zero. In the past we have hand-crafted code to work efficiently with sparse tensors, but now we have Taco, an open source compiler that can automatically generate code that can run up to 100 times faster.

http://i-programmer.info/news/202-number-crunching/11140-imagenet-training-record-24-minutes.html
http://i-programmer.info/news/202-number-crunching/11140-imagenet-training-record-24-minutes.htmlOne of the problems with neural networks is how long it takes to train them. Researchers have just smashed the training barrier by reducing the time to train ResNet from 14 days to one hour and have claimed a world record of 24 minutes for AlexNet with a lower hardware budget than used for the task by Facebook.

http://i-programmer.info/news/202-number-crunching/11092-as-much-fun-as-you-can-have-with-a-ball-and-hoop.html
http://i-programmer.info/news/202-number-crunching/11092-as-much-fun-as-you-can-have-with-a-ball-and-hoop.htmlHi, my name is Mike and I'm a recovering physicist. Or I was until I found this video.

OK, this one isn't going to be to everyone's taste, but I assure you it's fun. How do you control a ball inside a wheel when you only have control over the rotation of the wheel?

http://i-programmer.info/news/202-number-crunching/9707-better-than-floating-new-number-format-avoids-imprecision.html
http://i-programmer.info/news/202-number-crunching/9707-better-than-floating-new-number-format-avoids-imprecision.htmlIt is well known that the way computers do arithmetic isn't the same way we do arithmetic, but if you thought that IEEE 754 floating point was the last word then you need to rethink. A new format called unum saves bits in all senses of the word and promises better precision.

http://i-programmer.info/news/202-number-crunching/9378-let-herbie-make-your-floating-point-better.htmlA new tool from the University of Washington will take your floating point expressions and convert them into something that does the same calculation, but more accurately. This is worth knowing about.
