Reintroducing myself: I’m Omer, I’m an Engineer and [hibernating] Artist. I’m at NVIDIA Research. Before I worked on VR for a…decade? And much before that, in Film & TV.
I post about Mathematics, Graphics, Science, Music and lately, Geopolitics too. Sorry.

Chairing a conference is basically a flex of soft skills, what with writing soliciting emails, fitting a budget, and enforcing deadlines.

The coming @i3dsymposium.org will take place this May on the Lucasfilm campus in SF.
I will be serving as General Co-Chair.
We rely on industry collaborations and sponsorships to keep the quality high.

One of my favorite findings: Positional embeddings are just training wheels. They help convergence but hurt long-context generalization.
We found that if you simply delete them after pretraining and recalibrate for <1% of the original budget, you unlock massive context windows. Smarter, not harder.

Introducing DroPE: Extending Context by Dropping Positional Embeddings
We found embeddings like RoPE aid training but bottleneck long-sequence generalization. Our solution’s simple: treat them as a temporary training scaffold, not a permanent necessity.

I recently moved to Meta to work on AI for headsets and input systems.
My focus since the beginning of my Engineering career has been “Intelligence Close to the Senses”, and this feels like a natural step in the same direction.
I’ll still be active in AI and Graphics conferences.

WITCHING HOUR by Ladytron was released 20 years ago today. It was the highlight of the year for me, and helped me yearn for beauty at a time my life had very little of it.
Give this album a listen. It still sounds like it was made 5 years in the future.

SIGGRAPH’s response to concerns about safety in Kuala Lumpur is “thank you for your letter”. Disappointing.
I wasn’t planning on attending because the birthplace on my passport precludes me from being safe in Malaysia - but I guess this is now everybody’s problem.
