Validation of Matching

Ya Le, Eric Bax, Nicola Barbieri +3

We introduce a technique to compute probably approximately correct (PAC) bounds on precision and recall for matching algorithms. The bounds require some verified matches, but those…

Quantization Robustness of Monotone Operator Equilibrium Networks

James Li, Philip H. W. Leong, Thomas Chaffey

Monotone operator equilibrium networks are implicit-layer models whose output is the unique equilibrium of a monotone operator, guaranteeing existence, uniqueness, and convergence.…

Synergizing Implicit and Explicit User Interests: A Multi-Embedding Retrieval Framework at Pinterest

Zhibo Fan, Hongtao Lin, Haoyu Chen +4

Industrial recommendation systems are typically composed of multiple stages, including retrieval, ranking, and blending. The retrieval stage plays a critical role in generating a h…

VCG Payments for Portfolio Allocations in Online Advertising

James Li, Eric Bax, Nilanjan Roy +1

Some online advertising offers pay only when an ad elicits a response. Randomness and uncertainty about response rates make showing those ads a risky investment for online publishe…

Venus as an Exoplanet: I. An Initial Exploration of the 3-D Energy Balance for a CO Exoplanetary Atmosphere Around an M-Dwarf Star

Christopher D. Parkinson, Stephen W. Bougher, Franklin P. Mills +5

The chemical evolution of an exoplanetary Venus-like atmosphere is dependent upon the ultraviolet to near ultraviolet (FUV-NUV) radiation ratio from the parent star, the balance be…

Total Outcome Logic: Unified Reasoning for a Taxonomy of Program Logics

James Li, Noam Zilberstein, Alexandra Silva

While there is a long tradition of reasoning about (non)termination in program analysis, specialized logics are typically needed to give different termination criteria. This includ…

Exponential Weight Functions for Quasi-Proportional Auctions

Eric Bax, James Li, Zheng Wen

In quasi-proportional auctions, the allocation is shared among bidders in proportion to their weighted bids. The auctioneer selects a bid weight function, and bidders know the weig…

Revenue-Maximizing Mechanism Design for Quasi-Proportional Auctions

Zheng Wen, Eric Bax, James Li

In quasi-proportional auctions, each bidder receives a fraction of the allocation equal to the weight of their bid divided by the sum of weights of all bids, where each bid's weigh…

ST-PCNN: Spatio-Temporal Physics-Coupled Neural Networks for Dynamics Forecasting

Yu Huang, James Li, Min Shi +5

Ocean current, fluid mechanics, and many other spatio-temporal physical dynamical systems are essential components of the universe. One key characteristic of such systems is that c…
