Adversarial and bit-level fault attacks on multimodal and speech models, RLHF training-signal integrity, trust under corrupted majorities, and harm amplification in multi-agent LLM systems.
Topology-aware world models for electricity-grid reconfiguration — ranking line-switching candidates via learned imagined rollouts, verified by exact AC power-flow simulation.
Whether token-level logits, probabilities and generation-time signals from autoregressive LLMs give reliable evidence of incorrect or unsupported outputs.
Semantically targeted sparse parameter bit flips in speech-recognition models, with robustness and failure analysis.
Anchor-calibrated trusted/corrupted cohort recovery when corrupted sources form the majority.
Local-to-system harm amplification in multi-agent LLM systems — how compromised agents propagate failures.
Sparse bit-level fault analysis and semantic steering in quantized vision-language models.
Consensus-based reward mitigating malicious human-in-the-loop feedback during RLHF training of LLMs.
Meta-attack framework composing existing attack primitives to synthesize effective and stealthy adversarial examples.
