natural-agi
2023—presentPhD research on explainable image classification via structural graph analysis — no backpropagation, no neural networks. Raster images are skeletonised with Growing Neural Gas plus Ramer-Douglas-Peucker, then iterative structural reduction composes stable "concept" attractors per class. Classification runs on Graph Edit Distance between input and concepts under Winner-Take-All. Hits ~82% accuracy on few-shot MNIST with 5-6 samples per class and concepts that are explicit, visualisable graphs.
