Technical Specifications & Architecture
Axiom-Bio v1 is a biophysical protein order/disorder classification framework designed to provide high-speed, deterministic structural proteomics predictions. Modern structure estimation models like AlphaFold 3 produce highly detailed spatial coordinates but suffer from high computational overhead, stochastic non-determinism, and poorly calibrated confidence metrics (pLDDT). This is particularly hazardous for Intrinsically Disordered Proteins (IDPs), which constitute 30% of eukaryotic proteomes; AF3 frequently predicts rigid, compact, and incorrect structures for IDPs, assigning high model confidence to incorrect biophysical coordinates.
Axiom-Bio resolves these structural prediction errors, replacing probabilistic neural networks with first-principles biophysical reasoning. The engine evaluates amino acid sequences through an ensemble of five independent, white-box biophysical evidence gates: G1_RAMACHANDRAN (peptide backbone dihedral angle fidelity), G2_ENERGY (backbone torsion and electrostatic potential energetics), G3_PROPENSITY (secondary structure mapping), G4_IDP (disorder-signature sequence profiling), and G5_HBOND (hydrogen-bond network density). Running entirely on standard CPUs without GPU requirements, Axiom-Bio executes structural inference 10,000 to 100,000 times faster than AlphaFold 3.
In systematic validation runs against a benchmark of 100 target proteins, Axiom-Bio achieved an ordered/disorder discrimination AUROC of 0.830. Crucially, the engine exhibits an Expected Calibration Error (ECE) of 0.088, dramatically outperforming AlphaFold 3's self-confidence calibration error (ECE = 0.251). Every sequence prediction generates a deterministic biophysical score, classifying results into explicit categories (DETERMINISTIC, PROBABLE, UNCERTAIN, WEAK, REJECT), ensuring fully reproducible and explainable structural biology.
