1 min read
ArXiv

Analysis

This paper addresses the computational challenges of optimizing nonlinear objectives using neural networks as surrogates, particularly for large models. It focuses on improving the efficiency of local search methods, which are crucial for finding good solutions within practical time limits. The core contribution lies in developing a gradient-based algorithm with reduced per-iteration cost and further optimizing it for ReLU networks. The paper's significance is highlighted by its competitive and eventually dominant performance compared to existing local search methods as model size increases.

Joint Data Selection for LLM Pre-training

Published:Dec 30, 2025 14:38
1 min read
ArXiv

Analysis

This paper addresses the challenge of efficiently selecting high-quality and diverse data for pre-training large language models (LLMs) at a massive scale. The authors propose DATAMASK, a policy gradient-based framework that jointly optimizes quality and diversity metrics, overcoming the computational limitations of existing methods. The significance lies in its ability to improve both training efficiency and model performance by selecting a more effective subset of data from extremely large datasets. The 98.9% reduction in selection time compared to greedy algorithms is a key contribution, enabling the application of joint learning to trillion-token datasets.
Reference

“DATAMASK achieves significant improvements of 3.2% on a 1.5B dense model and 1.9% on a 7B MoE model.”

Adversarial Examples from Attention Layers for LLM Evaluation

Published:Dec 29, 2025 19:59
1 min read
ArXiv

Analysis

This paper introduces a novel method for generating adversarial examples by exploiting the attention layers of large language models (LLMs). The approach leverages the internal token predictions within the model to create perturbations that are both plausible and consistent with the model's generation process. This is a significant contribution because it offers a new perspective on adversarial attacks, moving away from prompt-based or gradient-based methods. The focus on internal model representations could lead to more effective and robust adversarial examples, which are crucial for evaluating and improving the reliability of LLM-based systems. The evaluation on argument quality assessment using LLaMA-3.1-Instruct-8B is relevant and provides concrete results.
Reference

“The results show that attention-based adversarial examples lead to measurable drops in evaluation performance while remaining semantically similar to the original inputs.”

Reliable Adversarial Robustness Evaluation for Spiking Neural Networks

Published:Dec 27, 2025 08:43
1 min read
ArXiv

Analysis

This paper addresses the challenge of evaluating the adversarial robustness of Spiking Neural Networks (SNNs). The discontinuous nature of SNNs makes gradient-based adversarial attacks unreliable. The authors propose a new framework with an Adaptive Sharpness Surrogate Gradient (ASSG) and a Stable Adaptive Projected Gradient Descent (SA-PGD) attack to improve the accuracy and stability of adversarial robustness evaluation. The findings suggest that current SNN robustness is overestimated, highlighting the need for better training methods.
Reference

“The experimental results further reveal that the robustness of current SNNs has been significantly overestimated and highlighting the need for more dependable adversarial training methods.”

1 min read
ArXiv

Analysis

This paper introduces a novel application of Bidirectional Liquid Neural Networks (BiLNN) to solve the optical model in nuclear physics. The key contribution is a fully differentiable emulator that maps optical potential parameters to scattering wave functions. This allows for efficient uncertainty quantification and parameter optimization using gradient-based algorithms, which is crucial for modern nuclear data evaluation. The use of phase-space coordinates enables generalization across a wide range of projectile energies and target nuclei. The model's ability to extrapolate to unseen nuclei suggests it has learned the underlying physics, making it a significant advancement in the field.
