We believe ARVR is among the most underrated markets today. Most people fixate on past (and current) missteps, leading to assumptions that are simply wrong.

With ~30m Meta Quest headsets sold and a favorable industry outlook, we think the time is now. ⬇️

UE 5.4 is out and the Learning Agents plugin got a bunch of updates!

One of the coolest new features is 'Structured Observations and Actions' - which provides a powerful and flexible way of describing the inputs and outputs of a Neural Network.

Build what you need and use what you build. This is a core philosophy of my research. It shifts the focus away from publishing “papers” to what really matters — impact. This thread unpacks why I think this is a successful approach to science. 1/10 Or see:

Returning from an experimental ~2 week detox from the internet. Main takeaway is that I didn't realize how unsettled the mind can get when over-stimulating on problems/information (like a stirred liquid), and ~2 weeks is enough to settle into a lot more zen state.

Lots of algorithms online for converting from rotation matrices to quaternions have unstable gradients when transcribed to PyTorch.

This is the best I've found and seems both smooth and stable (from this article by Mike Day d3cw3dd2w32x2b.cloudfront.net/wp-content/upl…):
