Armeet Singh Jatyani

AI Researcher @ Caltech

I'm currently on leave from Caltech to work on my startup Arcten, which was recently funded by Y Combinator.

Computer Science undergrad at Caltech researching AI, computer vision, neural operators, and medical imaging. I recently presented my work at CVPR 2025 and NeurIPS 2024, where I had the chance to meet some pretty remarkable people!

In Summer 25', I developed new kernel architectures for 3D MRI reconstruction.

A Unified Model for Compressed Sensing MRI Across Undersampling Patterns
CVPR 2025
We propose a unified MRI reconstruction model robust to various measurement undersampling patterns and image resolutions using neural operators. Our model improves SSIM by 11% and PSNR by 4 dB over state-of-the-art CNNs, with 600× faster inference than diffusion methods.
