Selecting Interpretable Circular Coordinates from Data
Vincent P. Grande, Marina Meila
Circular coordinates obtained from persistent cohomology reveal loop structure in data, but they usually remain abstract: A detected circle does not tell us which measured angle, p…
Isometry pursuit
Samson Koelle, Marina Meila
Isometry pursuit is a convex algorithm for identifying orthonormal column-submatrices of wide matrices. It consists of a novel normalization method followed by multitask basis purs…
How well behaved is finite dimensional Diffusion Maps?
Wenyu Bo, Marina MeilÄ
Under a set of assumptions on a family of submanifolds , we derive a series of geometric properties that remain valid after finite-dimensional and almost iso…
Optimal Design under Interference, Homophily, and Robustness Trade-offs
Vydhourie Thiyageswaran, Alex Kokot, Jennifer Brennan +3
To minimize the mean squared error (MSE) in global average treatment effect (GATE) estimation under network interference, a popular approach is to use a cluster-randomized design.…
Local EGOP for Continuous Index Learning
Alex Kokot, Anand Hemmady, Vydhourie Thiyageswaran +1
We introduce the setting of continuous index learning, in which a function of many variables varies only along a small number of directions at each point. For efficient estimation,…
Cryo-em images are intrinsically low dimensional
Luke Evans, Octavian-Vlad Murad, Lars Dingeldein +3
Simulation-based inference provides a powerful framework for cryo-electron microscopy, employing neural networks in methods like CryoSBI to infer biomolecular conformations via lea…
