Unconfounded Propensity Estimation for Unbiased Ranking

Kavli Affiliate: Dan Luo | First 5 Authors: [#item_custom_name[1]], [#item_custom_name[2]], [#item_custom_name[3]], [#item_custom_name[4]], [#item_custom_name[5]] | Summary: The goal of unbiased learning to rank (ULTR) is to leverage implicit user feedback for optimizing learning-to-rank systems. Among existing solutions, automatic ULTR algorithms that jointly learn user bias models (i.e., propensity models) with unbiased rankers have received a lot […]

Cross-view Action Recognition via Contrastive View-invariant Representation

Kavli Affiliate: Dan Luo | First 5 Authors: [#item_custom_name[1]], [#item_custom_name[2]], [#item_custom_name[3]], [#item_custom_name[4]], [#item_custom_name[5]] | Summary: Cross view action recognition (CVAR) seeks to recognize a human action when observed from a previously unseen viewpoint. This is a challenging problem since the appearance of an action changes significantly with the viewpoint. Applications of CVAR include surveillance and […]

High-resolution three-dimensional imaging of topological textures in single-diamond networks

Kavli Affiliate: Ulrich B. Wiesner | First 5 Authors:Dmitry Karpov, Kenza Djeghdi, Mirko Holler, S. Narjes Abdollahi, Karolina Godlewska | Summary: Highly periodic structures are often said to convey the beauty of nature. However, most material properties are strongly influenced by the defects they contain. On the mesoscopic scale, molecular self-assembly exemplifies this interplay; thermodynamic […]

Coherent control of the translational and point group symmetries of crystals with light

Kavli Affiliate: Nicole A. Benedek | First 5 Authors: Guru Khalsa, Jeffrey Z. Kaaret, Nicole A. Benedek | Summary: We use theory and first-principles calculations to explore mechanisms for control of the translational and point group symmetries of crystals in ultrafast optical experiments. We focus in particular on mechanisms that exploit anharmonic (biquadratic) lattice couplings […]
