10x the speed of what? lstm-compress achieves a ratio of 1.64 bpb with a speed of 4.4 kB/s, Bellard's LSTM (small) achieves the same ratio with a speed of 41.7 kB/s.

Most cars at dealerships don't have "dead" written on the windshield. I'm not sure what that means, but it doesn't sound that great.

I don't think that is a fair characterization of what I wrote. If the scanning process has a sensitivity of 99.999%, and the next stage in the signal chain has a sensitivity of 50%, and we consider what happens if the MRI sensitivity d

I don't have strong feelings about this, but a few thoughts come to mind regarding exploring accelerated MRIs via neural networks. 1. If an MRI can be done 10x faster with the same results except in exceptionally rare cases, might that

The radar module in Teslas uses the same filtering strategy as most adaptive cruise control radar modules, which is "if relative velocity to object is nearly the opposite of the car's velocity, throw it out." It works pretty

The issue is that tesla packaged up a radar designed for adaptive cruise control as part of their "autopilot." Maybe there is some disclaimer somewhere that says autopilot will happily run into stopped cars, but I don't know

So I know the ownership of IP produced on an engineer's own time is pretty dicey (even in California, where it depends on whether the work is in the same field as the company, or something), and most of the time employers seem to have

Using avian's example of a list of numbers of similar magnitude, sorting the numbers will not really be any better than just summing them directly, but Kahan summation will do better.

I think Titan RTX is a "perfect die," so to speak, so even if they used the maximum number of cores they possibly could for this demo, that same silicon is for sale.

I'm pretty sure toy story 1 didn't use ray tracing. Iirc cars was the first that did.

Sounds like the first thing you are describing is closer to ray casting. Ray tracing doesn't have the limitations you mention. Roughly speaking, ray tra in techniques are variations on the concept of tracing a ray from the camera back
