When can Multi-Site Datasets be Pooled for Regression? Hypothesis Tests, -consistency and Neuroscience Applications
Hao Henry Zhou, Yilin Zhang, Vamsi K. Ithapu +3
Many studies in biomedical and health sciences involve small sample sizes due to logistic or financial constraints. Often, identifying weak (but scientifically interesting) associa…
The Incremental Multiresolution Matrix Factorization Algorithm
Vamsi K. Ithapu, Risi Kondor, Sterling C. Johnson +1
Multiresolution analysis and matrix factorization are foundational tools in computer vision. In this work, we study the interface between these two distinct topics and obtain techn…
Accelerating Permutation Testing in Voxel-wise Analysis through Subspace Tracking: A new plugin for SnPM
Felipe Gutierrez-Barragan, Vamsi K. Ithapu, Chris Hinrichs +5
Permutation testing is a non-parametric method for obtaining the max null distribution used to compute corrected -values that provide strong control of false positives. In neuro…
On architectural choices in deep learning: From network structure to gradient convergence and parameter estimation
Vamsi K Ithapu, Sathya N Ravi, Vikas Singh
We study mechanisms to characterize how the asymptotic convergence of backpropagation in deep architectures, in general, is related to the network structure, and how it may be infl…
