Knowledge-Spreader: Learning Facial Action Unit Dynamics with Extremely Limited Labels

Posted by klaurent March 30, 2022April 11, 2022Berkeley

Kavli Affiliate: Xiang Zhang | First 5 Authors: Xiaotian Li, Xiang Zhang, Taoyue Wang, Lijun Yin, | Summary: Recent studies on the automatic detection of facial action unit (AU) have extensively relied on large-sized annotations. However, manually AU labeling is difficult, time-consuming, and costly. Most existing semi-supervised works ignore the informative cues from the temporal […]

Mesoscopic oblique plane microscopy (Meso-OPM) – enabling large-scale 4D isotropic cellular resolution imaging with a diffractive light sheet

Posted by klaurent March 30, 2022April 11, 2022Hopkins

Kavli Affiliate: Patrick Kanold | Authors: Wenjun Shao, Minzi Chang, Kevin Emmerich, Patrick O Kanold, Jeff S Mumm and Ji Yi | Summary: Fundamental understanding of large-scale dynamic connectivity within a living organism requires volumetric imaging over a large field of view (FOV) at biologically relevant speed and resolution. However, most microscopy methods make trade-offs […]

A Fast and Convergent Proximal Algorithm for Regularized Nonconvex and Nonsmooth Bi-level Optimization

Posted by klaurent March 30, 2022UCAS

Kavli Affiliate: Yi Zhou | First 5 Authors: Ziyi Chen, Bhavya Kailkhura, Yi Zhou, , | Summary: Many important machine learning applications involve regularized nonconvex bi-level optimization. However, the existing gradient-based bi-level optimization algorithms cannot handle nonconvex or nonsmooth regularizers, and they suffer from a high computation complexity in nonconvex bi-level optimization. In this work, […]

Searching for axion-like time-dependent cosmic birefringence with data from SPT-3G

Posted by March 30, 2022Stanford

Kavli Affiliate: Chao-Lin Kuo | First 5 Authors: K. R. Ferguson, A. J. Anderson, N. Whitehorn, P. A. R. Ade, M. Archipley | Summary: Ultralight axionlike particles (ALPs) are compelling dark matter candidates because of their potential to resolve small-scale discrepancies between $Lambda$CDM predictions and cosmological observations. Axion-photon coupling induces a polarization rotation in linearly […]

Why are we still using 3D masses for cluster cosmology?

Posted by klaurent March 30, 2022April 11, 2022Chicago

Kavli Affiliate: Salman Habib | First 5 Authors: Stijn N. B. Debackere, Henk Hoekstra, Joop Schaye, Katrin Heitmann, Salman Habib | Summary: The abundance of clusters of galaxies is highly sensitive to the late-time evolution of the matter distribution, since clusters form at the highest density peaks. However, the 3D cluster mass cannot be inferred […]
