Institute for Pure & Applied Mathematics (IPAM) via YouTube
Overview
Syllabus
Intro
Scaling language models
Data set sizes in imaging tasks are small
Expected performance behavior
U-net-based denoising
U-net-based accelerated MRI
Swin transformer based denoising
Reconstruction methods
What we might expect
Dataset shift
Adversarially filtered shift
Goal: improve performance unter distribution shifts
For classification problems, "natural distribution shifts are an open research problem"
Improving performance for 11-minimization is easy
Test time training
Closing the distribution shift performance gap for anatomy shift
Closing the distribution shift performance gap with test-time-training
