Acknowledgement Entity Recognition in CORD-19 Papers

1 code implementation EMNLP (sdp) 2020 Jian Wu, Pei Wang, Xin Wei, Sarah Rajtmajer, C. Lee Giles, Christopher Griffin

We built a supplementary database by linking CORD-19 papers with acknowledgement entities extracted by AckExtract including persons and organizations and find that only up to 50–60% of named entities are actually acknowledged.

Topological Learning in Multi-Class Data Sets

no code implementations23 Jan 2023 Christopher Griffin, Trevor Karn, Benjamin Apple

As a by-product, a topological classifier is defined that uses an open sub-covering of the data set.

Dynamics of a Binary Option Market with Exogenous Information and Price Sensitivity

no code implementations18 May 2022 Hannah Gampe, Christopher Griffin

Under general assumptions on purchasing rules, we show that when exogenous information is constant in the binary asset market, the price always converges.

Design and Analysis of a Synthetic Prediction Market using Dynamic Convex Sets

no code implementations5 Jan 2021 Nishanth Nakshatri, Arjun Menon, C. Lee Giles, Sarah Rajtmajer, Christopher Griffin

We show that under certain assumptions on the underlying geometry, the resulting synthetic prediction market can be used to arbitrarily closely approximate a binary function defined on a set of input data.

A Finite Population Destroys a Traveling Wave in Spatial Replicator Dynamics

no code implementations31 May 2020 Christopher Griffin, Riley Mummah, Russ deForest

The infinite population spatial replicator is identical to the model used by Vickers and our derivation justifies the addition of a diffusion to the replicator.

Modeling a Hidden Dynamical System Using Energy Minimization and Kernel Density Estimates

no code implementations8 Apr 2019 Trevor K. Karn, Steven Petrone, Christopher Griffin

In this paper we develop a kernel density estimation (KDE) approach to modeling and forecasting recurrent trajectories on a compact manifold.
