Explainable Multimodal Models for Critical Infrastructure

1 minute read

Published:

Critical infrastructure operators increasingly rely on multimodal perception systems that fuse imagery, acoustic signatures, and telemetry feeds. Unfortunately, explainability research has lagged the architectural complexity of these systems. I propose a governance framework that blends modal-specific rationales with a global semantic narrative aligned to operator workflows. The pipeline begins with disentangled encoders whose latent spaces are regularised to preserve modality provenance. During inference, each encoder emits a sparse explanation graph that ties salient observations back to physical phenomena, for example corrosion cues in thermal imagery or harmonic anomalies in vibration spectra.

Sustainable AI Pipelines Through Carbon-Aware MLOps

Sustainable artificial intelligence cannot be reduced to marginal improvements in data center efficiency. The discipline demands lifecycle accountability across model design, training, deployment, and retirement. In our lab we instrumented a carbon-aware orchestration layer that tags every pipeline component with energy provenance metadata sourced from regional grid emission factors. This instrumentation revealed that model retraining schedules, rather than inference, dominated our carbon budget. Armed with granular telemetry, we shifted heavy retraining batches to windows with high renewable penetration and substituted dense hyperparameter sweeps with Bayesian optimisation constrained by energy quotas.

Operationalizing LLM Governance with Enterprise Knowledge Graphs

Large language models amplify institutional knowledge yet they also magnify the risk of hallucinated citations and policy drift. My current research integrates enterprise knowledge graphs as both a grounding substrate and a verifiable audit trail. Retrieval augmented generation pipelines typically treat knowledge stores as passive context providers. I invert this relationship by requiring the model to declare explicit graph traversals before composing a response. Each traversal is validated against schema rules and access control policies so that the model cannot fabricate entities or reference embargoed data.

Interpretable Foundations for Trustworthy Agentic AI

Agentic artificial intelligence systems promise autonomous adaptation and self-directed problem solving, yet their adoption in regulated domains hinges on verifiable transparency. In recent deployments I have observed that practitioners still rely on coarse attribution estimates derived from gradient saliency maps, even though these signals often collapse under distributional drift. I argue that an interpretable agentic stack must start with causal specification of decision objectives. Structural causal models provide a formal scaffold that distinguishes policy intent from the mutable patterns surfaced by data-driven planners. By encoding policy constraints as counterfactual queries, it becomes possible to debug agent trajectories with surgical precision.

Field Experiments in Human-in-the-Loop Machine Learning

Laboratory benchmarks rarely capture the socio-technical friction encountered when machine learning systems operate alongside frontline practitioners. To investigate this gap, I designed a series of field experiments across public health clinics that employ human-in-the-loop triage models. The studies revealed that data scientists often underestimate the latency introduced by manual override pathways. Clinicians needed interpretable uncertainty cues, not binary predictions, in order to calibrate their trust. We therefore redesigned the interface to surface calibrated risk intervals and provenance notes summarising the data regimes most responsible for each recommendation.
