Efficient Preference Poisoning Attacks on Offline RLHF
This paper begins by pointing out that Human Feedback-based Offline Reinforcement Learning (RLHF) pipelines, such as those using DPO, are vulnerable to 'poisoning' of preference datasets. The researchers discovered a core property—that a single label flip moves the DPO gradient independently of parameters—and converted this into a structured discrete sparse approximation problem. To address this, two novel attack methods, 'Binary-Aware Lattice Attack (BAL-A)' and 'Binary Matching Pursuit Attack (BMP-A)', are proposed to systematically analyze the vulnerabilities of offline RLHF models and prove their recoverability.
Key takeaways
Offline RLHF (e.g., DPO) is highly susceptible to poisoning attacks on pre-collected preference datasets.
Label flip attacks possess a core property: they move the DPO gradient in a parameter-independent manner.
This vulnerability was converted into a structured discrete sparse approximation problem for analysis.
BAL-A solves the flip selection problem by utilizing Lattice Theory and reduction methods.

StreamIndex: Streaming Top-k for Memory-Constrained CSA
This technical brief introduces StreamIndex, a streaming Top-k mechanism designed for memory-constrained Compressed Sparse Attention (CSA).

StreamIndex solves this by providing a chunk-based driver to process and merge Top-k without materializing all intermediate values, enabling efficient operation over much longer sequence lengths.
Key takeaways
StreamIndex is a Triton implementation for CSA pipelines that are memory constrained.
Previous methods caused OOM issues on long sequences (S >= 65,536) due to the materialization of the entire intermediate score tensor.
