SAFE_20M

SAFE_20M is a transformer-based model designed for molecular generation tasks. This model was trained from scratch on the MOSES dataset, which has been converted from SMILES to the SAFE (SMILES Augmented For Encoding) format to enhance molecular representation for machine learning applications.

Evaluation Results

On the evaluation set, SAFE_20M achieved the following result:

Loss: 0.4024

Model Description

SAFE_20M leverages the SAFE framework to generate valid and diverse molecular structures. By converting the MOSES dataset from SMILES to SAFE format, the model benefits from improved molecular encoding, facilitating better performance in various applications such as:

Drug Discovery: Identifying potential drug candidates with desirable properties.
Materials Science: Designing new materials with specific characteristics.
Chemical Engineering: Innovating chemical processes and compounds.

SAFE Framework

The SAFE framework, integral to SAFE_20M, was introduced in the following paper:

Intended Uses & Limitations

Intended Uses

SAFE_20M is primarily intended for:

Generating Molecular Structures: Creating novel molecules with desired properties.
Exploring Chemical Space: Navigating the vast landscape of possible chemical compounds for research and development.
Assisting in Material Design: Facilitating the creation of new materials with specific functionalities.

Limitations

Validation Required: Outputs should be validated by domain experts before practical application.
Synthetic Feasibility: Generated molecules may not always be synthetically feasible.
Dataset Scope: The model's knowledge is limited to the chemical space represented in the MOSES dataset.

Training and Evaluation Data

The model was trained on the MOSES (MOlecular SEtS) dataset, a benchmark dataset for molecular generation. The dataset was converted from SMILES to the SAFE format to enhance molecular representation for machine learning tasks.
