Model documentation & parameters
Algorithm Version: Which model checkpoint to use (trained on different datasets).
Scaffolds: One or multiple scaffolds (or seed molecules), provided as '.'-separated SMILES. If empty, no scaffolds are used.
Number of samples: How many samples should be generated (between 1 and 50).
Beam size: Beam size used in beam search decoding (the higher the slower but better).
Seed: The random seed used for initialization.
Model card
Model Details: MoLeR is a graph-based molecular generative model that can be conditioned (primed) on scaffolds. The model decorates scaffolds with realistic structural motifs.
Developers: Krzysztof Maziarz and co-authors from Microsoft Research and Novartis (full reference at bottom).
Distributors: Developer's code wrapped and distributed by GT4SD Team (2023) from IBM Research.
Model date: Released around March 2022.
Model version: Model provided by original authors, see their GitHub repo.
Model type: An encoder-decoder-based GNN for molecular generation.
Information about training algorithms, parameters, fairness constraints or other applied approaches, and features: Trained by the original authors with the default parameters provided on GitHub.
Paper or other resource for more information: Learning to Extend Molecular Scaffolds with Structural Motifs (ICLR 2022).

Where to send questions or comments about the model: Open an issue on original author's GitHub repository.
Intended Use. Use cases that were envisioned during development: Chemical research, in particular drug discovery.
Primary intended uses/users: Researchers and computational chemists using the model for model comparison or research exploration purposes.
Out-of-scope use cases: Production-level inference, producing molecules with harmful properties.
Factors: Not applicable.
Metrics: Validation loss on decoding correct molecules. Evaluated on several downstream tasks.
Datasets: 1.5M drug-like molecules from GuacaMol benchmark. Finetuning on 20 molecular optimization tasks from GuacaMol.
Ethical Considerations: Unclear, please consult with original authors in case of questions.
Caveats and Recommendations: Unclear, please consult with original authors in case of questions.
