  • Beyond generative models: superfast traversal ...

    perform interpolation and exploration in the chemical space, comparable to deep generative models. STONED bypasses the need for large amounts of data and training times by using string modifiions in the SELFIES molecular representation. First, we achieve nontrivial performance on typical benchmarks for generative models without any training. Additionally, we .
