Differentiable VQ-VAE's for Robust White Matter Streamline Encodings

1 code implementation10 Nov 2023 Andrew Lizarraga, Brandon Taraku, Edouardo Honig, Ying Nian Wu, Shantanu H. Joshi

Given the complex geometry of white matter streamlines, Autoencoders have been proposed as a dimension-reduction tool to simplify the analysis streamlines in a low-dimensional latent spaces.

StreamNet: A WAE for White Matter Streamline Analysis

no code implementations3 Sep 2022 Andrew Lizarraga, Katherine L. Narr, Kirsten A. Donald, Shantanu H. Joshi

This proposed framework takes advantage of geometry-preserving properties of the Wasserstein-1 metric in order to achieve direct encoding and reconstruction of entire bundles of streamlines.

SrvfNet: A Generative Network for Unsupervised Multiple Diffeomorphic Shape Alignment

no code implementations27 Apr 2021 Elvis Nunez, Andrew Lizarraga, Shantanu H. Joshi

We present SrvfNet, a generative deep learning framework for the joint multiple alignment of large collections of functional data comprising square-root velocity functions (SRVF) to their templates.
