Developer Recounts ML Representation Potholes: 128 Unordered Atoms Per Image
pixlpa · x · 2026-07-30
A developer shared a retrospective on a 4-month machine learning experiment. The project initially set out to explore whether a Gabor Image Representation could be learned, leading to multiple approaches and dead ends.
The author highlighted a recent tricky modeling difficulty: each image contains 128 or 256 atoms, and each atom has 12 parameters. Crucially, there is no defined ordering among these atoms, making the data structure highly difficult for the model to process and represent effectively.
