Joint Cryo-ET Alignment and Reconstruction with Neural Deformation Fields

no code implementations26 Nov 2022 Valentin Debarnot, Sidharth Gupta, Konik Kothari, Ivan Dokmanic

We show that our approach enables the recovery of high-frequency details that are destroyed without accounting for deformations.

Cryogenic Electron Tomography

Karyotype AI for Precision Oncology

no code implementations20 Nov 2022 Zahra Shamsi, Drew Bryant, Jacob Wilson, Xiaoyu Qu, Avinava Dubey, Konik Kothari, Mostafa Dehghani, Mariya Chavarha, Valerii Likhosherstov, Brian Williams, Michael Frumkin, Fred Appelbaum, Krzysztof Choromanski, Ali Bashir, Min Fang

These individual chromosomes were used to train and assess deep learning models for classifying the 24 human chromosomes and identifying chromosomal aberrations.

Few-Shot Learning Inductive Bias

Differentiable Uncalibrated Imaging

1 code implementation18 Nov 2022 Sidharth Gupta, Konik Kothari, Valentin Debarnot, Ivan Dokmanić

We propose a differentiable imaging framework to address uncertainty in measurement coordinates such as sensor locations and projection angles.

Image Reconstruction

Globally Injective ReLU Networks

no code implementations15 Jun 2020 Michael Puthawala, Konik Kothari, Matti Lassas, Ivan Dokmanić, Maarten de Hoop

Injectivity plays an important role in generative models where it enables inference; in inverse problems and compressed sensing with generative priors it is a precursor to well posedness.

Learning the geometry of wave-based imaging

1 code implementation NeurIPS 2020 Konik Kothari, Maarten de Hoop, Ivan Dokmanić

We propose a general physics-based deep learning architecture for wave-based imaging problems.

Inductive Bias Position

Random mesh projectors for inverse problems

1 code implementation ICLR 2019 Sidharth Gupta, Konik Kothari, Maarten V. de Hoop, Ivan Dokmanić

We show that in this case the common approach to directly learn the mapping from the measured data to the reconstruction becomes unstable.
