Research on Superalignment Should Advance Now with Parallel Optimization of Competence and Conformity

no code implementations8 Mar 2025 HyunJin Kim, Xiaoyuan Yi, Jing Yao, Muhua Huang, JinYeong Bak, James Evans, Xing Xie

The recent leap in AI capabilities, driven by big generative models, has sparked the possibility of achieving Artificial General Intelligence (AGI) and further triggered discussions on Artificial Superintelligence (ASI), a system surpassing all humans across all domains.

Linear Representations of Political Perspective Emerge in Large Language Models

1 code implementation3 Mar 2025 Junsol Kim, James Evans, Aaron Schein

This paper studies how LLMs are seemingly able to reflect more liberal versus more conservative viewpoints among other political perspectives in American politics.

Hidden Persuaders: LLMs' Political Leaning and Their Influence on Voters

1 code implementation31 Oct 2024 Yujin Potter, Shiyang Lai, Junsol Kim, James Evans, Dawn Song

Through a voting simulation, we first demonstrate 18 open- and closed-weight LLMs' political preference for a Democratic nominee over a Republican nominee.

China's Rising Leadership in Global Science

no code implementations9 Jun 2024 Renli Wu, Christopher Esposito, James Evans

Major shifts in the global system of science and technology are destabilizing the global status order and demonstrating the capacity for emerging countries like China and India to exert greater influence.

Modularity, Higher-Order Recombination, and New Venture Success

no code implementations23 May 2024 Likun Cao, Ziwen Chen, James Evans

Modularity is critical for the emergence and evolution of complex social, natural, and technological systems robust to exploratory failure.

Can Large Language Model Agents Simulate Human Trust Behavior?

1 code implementation7 Feb 2024 Chengxing Xie, Canyu Chen, Feiran Jia, Ziyu Ye, Shiyang Lai, Kai Shu, Jindong Gu, Adel Bibi, Ziniu Hu, David Jurgens, James Evans, Philip Torr, Bernard Ghanem, Guohao Li

In this paper, we focus on one critical and elemental behavior in human interactions, trust, and investigate whether LLM agents can simulate human trust behavior.

Accelerating science with human-aware artificial intelligence

no code implementations2 Jun 2023 Jamshid Sourati, James Evans

Artificial intelligence (AI) models trained on published scientific findings have been used to invent valuable materials and targeted therapies, but they typically ignore the human scientists who continually alter the landscape of discovery.

Complementary artificial intelligence designed to augment human discovery

no code implementations2 Jul 2022 Jamshid Sourati, James Evans

When we evaluate the promise of our predictions with first-principles equations, we demonstrate that increased complementarity of our predictions does not decrease and in some cases increases the probability that the predictions possess the targeted properties.

Semantic maps and metrics for science Semantic maps and metrics for science using deep transformer encoders

no code implementations13 Apr 2021 Brendan Chambers, James Evans

Finally, with the goal of leveraging contextual representations from deep encoders, we present a range of measurements for understanding and forecasting research communities in science.

Accelerating science with human versus alien artificial intelligences

no code implementations12 Apr 2021 Jamshid Sourati, James Evans

These AI approaches typically ignore the distribution of human prediction engines -- scientists and inventor -- who continuously alter the landscape of discovery and invention.

Information Lattice Learning

no code implementations1 Jan 2021 Haizi Yu, James Evans, Lav R. Varshney

ILL focuses on explainability and generalizability from "small data", and aims for rules akin to those humans distill from experience (rather than a representation optimized for a specific task like classification).

Long-range Event-level Prediction and Response Simulation for Urban Crime and Global Terrorism with Granger Networks

no code implementations4 Nov 2019 Timmy Li, Yi Huang, James Evans, Ishanu Chattopadhyay

Large-scale trends in urban crime and global terrorism are well-predicted by socio-economic drivers, but focused, event-level predictions have had limited success.

Science and Technology Advance through Surprise

no code implementations18 Oct 2019 Feng Shi, James Evans

Breakthrough discoveries and inventions involve unexpected combinations of contents including problems, methods, and natural entities, and also diverse contexts such as journals, subfields, and conferences.

Wasserstein Soft Label Propagation on Hypergraphs: Algorithm and Generalization Error Bounds

no code implementations6 Sep 2018 Tingran Gao, Shahab Asoodeh, Yi Huang, James Evans

Inspired by recent interests of developing machine learning and data mining algorithms on hypergraphs, we investigate in this paper the semi-supervised learning algorithm of propagating "soft labels" (e. g. probability distributions, class membership scores) over hypergraphs, by means of optimal transportation.

Curvature of Hypergraphs via Multi-Marginal Optimal Transport

no code implementations22 Mar 2018 Shahab Asoodeh, Tingran Gao, James Evans

We introduce a novel definition of curvature for hypergraphs, a natural generalization of graphs, by introducing a multi-marginal optimal transport problem for a naturally defined random walk on the hypergraph.

Adaptive Sampling for Coarse Ranking

1 code implementation20 Feb 2018 Sumeet Katariya, Lalit Jain, Nandana Sengupta, James Evans, Robert Nowak

We consider the problem of active coarse ranking, where the goal is to sort items according to their means into clusters of pre-specified sizes, by adaptively sampling from their reward distributions.

The Wisdom of Polarized Crowds

no code implementations29 Nov 2017 Feng Shi, Misha Teplitskiy, Eamon Duede, James Evans

Our analysis then reveals that polarized teams---those consisting of a balanced set of politically diverse editors---create articles of higher quality than politically homogeneous teams.
