## Abstract
The blood-brain barrier (BBB) restricts most compounds from entering the brain, making BBB permeability prediction crucial for drug discovery. Experimental assays are costly and limited, motivating computational approaches. While machine learning has shown promise, combining chemical descriptors with deep learning embeddings remains underexplored. Here, we introduce TITAN-BBB, a multi-modal architecture that combines tabular, image, and text-based features via attention mechanism. To evaluate, we aggregated multiple literature sources to create the largest BBB permeability dataset to date, enabling robust training for both classification and regression tasks. Our results demonstrate that TITAN-BBB achieves 86.5% of balanced accuracy on classification tasks and 0.436 of mean absolute error for regression. Our approach also outperforms state-of-the-art models in both classification and regression performance, demonstrating the benefits of combining deep and domain-specific representations.
## Dataset Details
This dataset is an aggregation of different literature sources (please see the paper to check the references).
### Classification Task
The number of samples for BBB- and BBB+ is presented below (corresponding to TABLE I in the paper).
| Set Name | BBB+ | BBB- |
| :--------- | -----: | -----: |
| Training | 4,564 | 3,029 |
| Validation | 434 | 293 |
| Test | 638 | 304 |
| **Total** | **5,636** | **3,626** |
### Regression Task
For the regression task, based on the classification dataset, only compounds with logBB values were utilized. This resulted in a subset with 963 samples for training, 84 samples for validation, and 100 samples for testing.
## Dataset Usage
