Cross-City Building Age Classification
Predict the majority construction-age class of buildings inside 30 m Landsat pixels from decades of spectral reflectance, trained on Madrid and transferred to Amsterdam. Class-conditional CORAL lifts zero-shot macro-F1 from 0.36 to 0.65 with no Amsterdam labels.
Does AI Actually Know Itself?
A capability-controlled test of whether LLM self-prediction reflects privileged self-access, or is just stylometry in disguise. Asked which of two replies it would produce, Hermes-3 discriminated its own output above chance. A one-feature 'pick the longer reply' rule beat it anyway.
AfriGuard
A multilingual AI safety benchmark evaluating how well frontier LLMs maintain safety guardrails across South African languages. We red-teamed four models in seven languages, measuring Attack Success Rate across regionally relevant harms. Safety alignment catastrophically degrades outside of English.
Discipline over intensity.
Consistency over bursts.
I grew up with early access to technology, getting my first computer at age five, and watching my father build his career at the heart of South African data. That environment shaped how I think. I'm not in a hurry. I'm building a foundation that lasts.
