Closed-Form Steepest Descent Direction toward Flat Minima: Reducing Upper Bounds on the Loss Hessian Eigenspectrum in Neural Networks

Yuto Omae, Kazuki Sakai, Yohei Kakimoto, Makoto Sasaki +2 more

This paper derives the gradient of the Wolkowicz-Styan upper bound on the maximum eigenvalue of the cross-entropy loss Hessian in three-layer NNs to characterize directions leading to flat minima and…

Domain Adaptation and Reasoning Frameworks in Language Models: A Controlled Experiment with Historical Cosmology

Francesco De Bernardis

The study demonstrates that domain adaptation primarily reshapes the linguistic explanatory framework of language models, causing shifts in cosmological stance secondarily, rather than directly modify…

Perceived AGI: Believability as Dimensional Completeness, Not Capability

Sebastian Cochinescu

The authors propose a framework for enhancing the believability of large language models in one-to-one conversation by focusing on dimensional completeness and expressing first-person stances in the a…

Geometric Latent Reasoning Induces Shorter Generations in LLMs

Shashi Kumar, Yacouba Kaloga, Petr Motlicek, Ina Kodrasi +1 more

The paper introduces Geometric Latent Reasoning (GLR), a method that models reasoning as continuous paths in the embedding space, showing that this continuous approach allows LLMs to solve problems us…

Frequencies of Patterns in Smooth Sequences Over the Alphabet $\{1,3\}$

Damien Jamet, Irène Marcovici, Léo Poirier, Thierry de la Rue

This paper uses ergodic theory to study statistical properties of smooth sequences over the odd alphabet {1,3}, defining a notion of type for those sequences and proving unique ergodicity for subshift…

Conjectural Decidability of the Skolem Problem

Florian Luca, Joël Ouaknine, James Worrell

This paper introduces the concept of 'large' zeros in linear recurrence sequences and establishes that they either do not exist or are very sparse, which could lead to decidability of the Skolem Probl…

Perceive-to-Reason: Decoupling Perception and Reasoning for Fine-Grained Visual Reasoning

Hongxing Li, Xiufeng Huang, Dingming Li, Wenjing Jiang +10 more

This paper proposes Perceive-to-Reason (P2R), a framework for fine-grained visual reasoning that decouples perception from reasoning and introduces a new reinforcement learning strategy.
