Model Overview

StableProt is a structure-aware deep learning framework for predicting protein melting temperature ($T_m$) and host organism optimal growth temperature (OGT).

By coupling SaProt 650M Foldseek 3Di structural tokens with parameter-isolated dual neural projection heads and observation-level uncertainty estimation, StableProt delivers continuous point estimates alongside calibrated 95% predictive intervals.

Repository Contents

This repository hosts the weights for the 5-seed production ensemble:

• seed1/ to seed5/: PyTorch state dicts (model_tm.pt and model_ogt.pt).
• config.json: Architecture specifications and projection head hyperparameters.
• normalization_stats.json: Ground-truth z-score normalization parameters (tm_mean, tm_std, ogt_mean, ogt_std).

Loading Model Weights

import torch
import json

# 1. Load normalization parameters
with open("normalization_stats.json", "r") as f:
    norm_stats = json.load(f)

# 2. Load trained weights for a specific seed (e.g. seed 1)
tm_state = torch.load("seed1/model_tm.pt", map_location="cpu", weights_only=False)
ogt_state = torch.load("seed1/model_ogt.pt", map_location="cpu", weights_only=False)

print("StableProt model weights loaded successfully!")
