Attentional Graph Neural Networks for Robust Massive Network Localization

no code implementations28 Nov 2023 Wenzhong Yan, Juntao Wang, Feng Yin, Yang Tian, Abdelhak M. Zoubir

To tap the potential of GNNs in regression, this paper integrates GNNs with attention mechanism, a technique that revolutionized sequential learning tasks with its adaptability and robustness, to tackle a challenging nonlinear regression problem: network localization.

Machine Learning on generalized Complete Intersection Calabi-Yau Manifolds

no code implementations21 Sep 2022 Wei Cui, Xin Gao, Juntao Wang

Generalized Complete Intersection Calabi-Yau Manifold (gCICY) is a new construction of Calabi-Yau manifolds established recently.

Cursed yet Satisfied Agents

no code implementations2 Apr 2021 YiLing Chen, Alon Eden, Juntao Wang

In contrast, we show that for sum-concave valuations, which include weighted-sum valuations and l_p-norms, the welfare optimal EPBB mechanism obtains half of the optimal welfare as the number of agents grows large.

Replication Markets: Results, Lessons, Challenges and Opportunities in AI Replication

no code implementations10 May 2020 Yang Liu, Michael Gordon, Juntao Wang, Michael Bishop, Yi-Ling Chen, Thomas Pfeiffer, Charles Twardy, Domenico Viganola

We will discuss opportunities and challenges of using these approaches to monitor and improve the credibility of research areas in Computer Science, AI, and ML.

Forecast Aggregation via Peer Prediction

no code implementations9 Oct 2019 Juntao Wang, Yang Liu, Yi-Ling Chen

In this paper, we study the problem of aggregating forecasts without having historical performance data.

Randomized Wagering Mechanisms

no code implementations11 Sep 2018 Yiling Chen, Yang Liu, Juntao Wang

We show that a broad family of randomized wagering mechanisms satisfy all desirable theoretical properties.

Learning with noisy labels

Surrogate Scoring Rules

no code implementations26 Feb 2018 Yang Liu, Juntao Wang, Yi-Ling Chen

We show that, with a single bit of information about the prior distribution of the random variables, SSR in a multi-task setting recover SPSR in expectation, as if having access to the ground truth.

Observations of Reconnection Flows in a Flare on the Solar Disk

1 code implementation29 Aug 2017 Juntao Wang, P. J. A. Simoes, N. L. S. Jeffrey, L. Fletcher, P. J. Wright, I. G. Hannah

Magnetic reconnection is a well-accepted part of the theory of solar eruptive events, though the evidence is still circumstantial.
