ReMoDetect: Reward Models Recognize Aligned LLM's Generations

2 code implementations27 May 2024 Hyunseok Lee, Jihoon Tack, Jinwoo Shin

Based on this finding, we propose two training schemes to further improve the detection ability of the reward model, namely (i) continual preference fine-tuning to make the reward model prefer aligned LGTs even further and (ii) reward modeling of Human/LLM mixed texts (a rephrased texts from human-written texts using aligned LLMs), which serves as a median preference text corpus between LGTs and human-written texts to learn the decision boundary better.

Competition on the edge of an expanding population

no code implementations18 Jan 2023 Daniel W. Swartz, Hyunseok Lee, Mehran Kardar, Kirill S. Korolev

In growing populations, the fate of mutations depends on their competitive ability against the ancestor and their ability to colonize new territory.

Slow expanders invade by forming dented fronts in microbial colonies

1 code implementation9 Aug 2021 Hyunseok Lee, Jeff Gore, Kirill S. Korolev

In particular, the theory predicted that a slower, but more competitive, mutant forms a dented V-shaped sector as it takes over the expansion front.

Representations of degenerate poly-Bernoulli polynomials

no code implementations11 Dec 2020 TaeKyun Kim, Dae San Kim, Jongkyum Kwon, Hyunseok Lee

Recently, as degenerate version of such functions and polynomials, degenerate polylogarithm functions were introduced and degenertae poly-Bernoulli polynomials were defined by means of the degenerate polylogarithm functions, and some their properties were investigated.

Representations of degenerate Hermite polynomials

no code implementations28 Oct 2020 TaeKyun Kim, Dae San Kim, Lee-Chae Jang, Hyunseok Lee, Hanyoung Kim

We introduce degenerate Hermite polynomials as a degenerate version of the ordinary Hermite polynomials.

Identities on poly-Dedekind sums

no code implementations10 Sep 2020 TaeKyun Kim, Dae San Kim, Hyunseok Lee, Lee-Chae Jang

Dedekind sums occur in the transformation behaviour of the logarithm of the Dedekind eta-function under substitutions from the modular group.
