Learned Compression of SAR Phase-History Data: A Rate-Honest Feasibility Study on GOTCHA
Alizishaan Khatri
On-board compression of synthetic aperture radar (SAR) phase history is bandwidth-critical, and block-adaptive quantization (BAQ) remains the operational standard. We test whether…
Same Probe, Different Numbers: Are Activation Probes Robust to Inference-Time Numerical Non-Determinism?
Alizishaan Khatri
Activation probes are increasingly used to monitor LLMs in deployment. A probe is typically trained under one inference configuration, then used under whatever batch size and numer…
Safety Beyond the Interface: Detecting Harm via Latent States in Large Language Models
Alizishaan Khatri, Chiquita Prabhu, Omkar Neogi
Autonomous systems increasingly rely on Large Language Models (LLMs) yet the safety infrastructure surrounding these models introduces latency and compute overhead. This limits uti…
Probing the Prefill: Detecting Code Vulnerabilities via Latent Activations
Alizishaan Khatri
LLM-based code generation is now embedded in mission-critical pipelines, but defenses against vulnerable output remain post-hoc -- static analyzers, fine-tuned classifiers, or an L…
Do All LLMs Know When They're Being Harmful? A Reproducibility Study of Latent-Space Safety Probes Across Model Families
Alizishaan Khatri, Dun Li Chan
Khatri et al. (2026) [DOI: 10.1109/DSN-W70714.2026.00027] show that lightweight MLP probes on final-layer activations of a single 8B model (LLaMA-3.1-8B) detect harmful prompts at…
Latent Space Probing for Adult Content Detection in Video Generative Models
Alizishaan Khatri, Chiquita Prabhu
The rapid proliferation of AI-powered video generation systems has introduced significant challenges in content moderation, particularly with respect to adult and sexually explicit…
Preventing overfitting in deep learning using differential privacy
Alizishaan Anwar Hussein Khatri
The use of Deep Neural Network based systems in the real world is growing. They have achieved state-of-the-art performance on many image, speech and text datasets. They have been s…
