3D Deformable Protein Shapes Classification based on Triangles-Stars and Composite Deep Neural Networks
Bibliographic record
Abstract
In this paper, the problem of 3D protein deformable shape classification is addressed. Proteins are macromolecules with deformable shapes, their classification based only on their molecular surfaces is challenging problem. In addition, the protein shapes are related to their functions which makes their classification an important task. Triangular meshes (graphs) my be considered to represent the protein molecular surfaces. In this paper, we propose a new deep learning-based approach for 3D protein deformable shape classification. We propose a 3D deformable shape descriptor and a composite deep neural network. The shape descriptor is based on a set of global and local features resulting from the decomposition of protein 3D shapes into triangles-stars, following the different neighborhood order considered. The classification is performed by a composite deep neural network, each branch corresponding to a neighborhood order. The proposed approach is evaluated against 3D protein benchmark repositories and state-of-the-art methods. Our experimental results show and demonstrate the high performances and the effectiveness of our approach.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
