STRIDE: Training Data Attribution via Sparse Recovery from Subset Perturbations
STRIDE addresses a fundamental bottleneck in training data attribution for LLMs by shifting from parameter-space gradient tracking to activation-space modeling. Rather than repeatedly retraining models to measure causal influence, the framework uses sparse recovery to estimate how training examples shape model outputs. This matters because attribution remains critical for auditing, debugging, and defending against data poisoning, yet existing methods don't scale to billion-parameter models. The activation-space approach sidesteps both computational expense and the brittleness of local approximations, potentially unlocking interpretability at production scale.62
Beyond Text Following: Repairable Arbitration Reversals in Audio-Language Models
Researchers have identified a critical failure mode in audio-language models: when text and audio conflict, these systems systematically prefer text despite clear audio evidence. Using counterfactual analysis across five ALMs, the team found that 64% of conflict cases flip their preference when conflicting text is removed, indicating the audio signal is encoded but loses an internal arbitration process. Activation patching traces this reversal to answer-generation layers. This finding exposes a fundamental alignment problem in multimodal systems and suggests that training procedures may inadvertently teach models to weight text over sensory input, with implications for reliability in real-world deployment.62
Streaming Communication in Multi-Agent Reasoning
StreamMA challenges the conventional serial pipeline in multi-agent reasoning by enabling agents to consume partial outputs from upstream peers in real time rather than waiting for complete chains.
