ArXiv

Analysis

This paper addresses a critical issue in Retrieval-Augmented Generation (RAG): the inefficiency of standard top-k retrieval, which often includes redundant information. AdaGReS offers a novel solution by introducing a redundancy-aware context selection framework. This framework optimizes a set-level objective that balances relevance and redundancy, employing a greedy selection strategy under a token budget. The key innovation is the instance-adaptive calibration of the relevance-redundancy trade-off parameter, eliminating manual tuning. The paper's theoretical analysis provides guarantees for near-optimality, and experimental results demonstrate improved answer quality and robustness. This work is significant because it directly tackles the problem of token budget waste and improves the performance of RAG systems.

Key Takeaways

•Addresses the problem of redundant context in RAG.
•Proposes AdaGReS, a redundancy-aware context selection framework.
•Employs a greedy selection strategy with a token budget.
•Features instance-adaptive calibration to eliminate manual tuning.
•Demonstrates improved answer quality and robustness in experiments.

RepetitionCurse: DoS Attacks on MoE LLMs

Published:Dec 30, 2025 05:24

•

1 min read

•

ArXiv

Analysis

This paper highlights a critical vulnerability in Mixture-of-Experts (MoE) large language models (LLMs). It demonstrates how adversarial inputs can exploit the routing mechanism, leading to severe load imbalance and denial-of-service (DoS) conditions. The research is significant because it reveals a practical attack vector that can significantly degrade the performance and availability of deployed MoE models, impacting service-level agreements. The proposed RepetitionCurse method offers a simple, black-box approach to trigger this vulnerability, making it a concerning threat.

Key Takeaways

•MoE LLMs are vulnerable to DoS attacks due to routing imbalances.
•Adversarial prompts can force all tokens to be routed to a small subset of experts.
•RepetitionCurse is a simple, black-box method to exploit this vulnerability.
•The attack significantly increases inference latency and degrades service availability.

Balancing Diversity and Precision in LLM Next Token Prediction

•

1 min read

•

ArXiv

Analysis

This paper investigates how to improve the exploration space for Reinforcement Learning (RL) in Large Language Models (LLMs) by reshaping the pre-trained token-output distribution. It challenges the common belief that higher entropy (diversity) is always beneficial for exploration, arguing instead that a precision-oriented prior can lead to better RL performance. The core contribution is a reward-shaping strategy that balances diversity and precision, using a positive reward scaling factor and a rank-aware mechanism.

Key Takeaways

•Proposes a method to reshape the pre-trained token-output distribution for better RL exploration.
•Introduces a reward-shaping strategy that balances diversity and precision.
•Finds that a precision-oriented prior can be more beneficial for RL than a diversity-focused one.

Reference

“Contrary to the intuition that higher distribution entropy facilitates effective exploration, we find that imposing a precision-oriented prior yields a superior exploration space for RL.”

ArXiv NLP

Analysis

This paper introduces a novel method using sparse autoencoders (SAEs) to identify competency gaps in large language models (LLMs) and imbalances in their benchmarks. The approach extracts SAE concept activations and computes saliency-weighted performance scores, grounding evaluation in the model's internal representations. The study reveals that LLMs often underperform on concepts contrasting sycophancy and related to safety, aligning with existing research. Furthermore, it highlights benchmark gaps, where obedience-related concepts are over-represented, while other relevant concepts are missing. This automated, unsupervised method offers a valuable tool for improving LLM evaluation and development by identifying areas needing improvement in both models and benchmarks, ultimately leading to more robust and reliable AI systems.

Key Takeaways

•Sparse autoencoders can effectively identify competency gaps in LLMs.
•LLMs often struggle with concepts related to safety and resisting sycophancy.
•Benchmarks may have imbalanced coverage, over-representing certain concepts.

Reference

“We found that these models consistently underperformed on concepts that stand in contrast to sycophantic behaviors (e.g., politely refusing a request or asserting boundaries) and concepts connected to safety discussions.”
