How can GeoBFN's methodology be applied to other molecular tasks

GeoBFNの方法論は、他の分子タスクに適用することができます。例えば、タンパク質デザインや化合物設計などの分野で活用される可能性があります。GeoBFNは異なるモダリティからの変数を扱うため、さまざまな分子関連タスクに適応させることができます。また、条件つき生成や特定プロパティへの最適化など、幅広い分子関連課題にも応用可能です。

What are the potential limitations or drawbacks of using GeoBFN for 3D molecule generation

3D分子生成におけるGeoBFNの使用にはいくつかの潜在的な制限や欠点が考えられます。例えば、入力変数間の相互依存性を正確にモデル化する必要があるため、高度なモデリング技術と大規模なトレーニングデータセットが必要です。また、サンプリング手法やパラメータチューニングによって結果が大きく影響を受ける可能性もあります。さらに、一部の場合では生成された構造が化学的有効性を満たさず不安定であったり、多様性不足だったりすることも考えられます。
