Prompt-Injection Probes Learn the Conversation, Not Just the Injection
Kaan Kale, Sriram Vishwanath
Linear probes on a model's hidden states are used as cheap monitors for indirect prompt injection: they screen the tool outputs an agent reads and send suspicious ones to a slower…
WaveCommitments: Private and Verifiable Speech-Agent Marketplaces
Oguzhan Baser, Kaan Kale, Sriram Vishwanath +1
Modern speech systems are evolving into ecosystems of autonomous speech agents that interact, negotiate, and trade assets such as embeddings, spectrograms, or raw data. In such mar…
ModalFidelity: Routing Modalities for Deepfake Detection on a Budget
Oguzhan Baser, Kaan Kale, Sriram Vishwanath +1
Deepfakes no longer need to fake a whole video. Generators that read the transcript now alter only the few seconds in which a video's meaning turns, so a forgery hides in a small,…
The Key Handoff: Retrieval in Hybrid Language Models
Kaan Kale, Oguzhan Baser, Sriram Vishwanath
A two-hop question makes a language model retrieve twice: once to produce a bridge entity, and once to retrieve with it. Transformers resolve that entity in their early layers. Hyb…
RoboShape: Information-Theoretic Point Cloud Representations for Privacy-Aware Robot Perception
Oguzhan Baser, Mirac Sozen, Kaan Kale +2
With the increased adoption of robotic agents operating in human environments by scanning and sharing 3D representations (e.g., for fleet learning, cloud-based planning, or collabo…
VeryTrace: Verifying Reasoning Traces through Compilable Formalism and Structured Verification
Ninghan Zhong, Ahmet Ege Tanriverdi, Kaan Kale +1
Multi-step reasoning with Chain-of-Thought (CoT) prompting remains fragile: logical errors or hallucinations in early steps silently propagate, producing confident but incorrect co…
