We’re very excited to share BoltzGen — a biomolecular binder design model that matches state-of-the-art folding and turns that capability into generalizable binder design!

Unlike prior tools, BoltzGen spans nanobodies, miniproteins, peptides, and cyclic scaffolds and designs binders for proteins, nucleic acids, small molecules, and more. A declarative specification language (binding sites, covalents, structure groups, secondary structure, design masks) lets you steer generation toward precise objectives. With multiple wet-lab partners, we validated across diverse targets. On 9 novel protein targets (no similar bound complexes in PDB), testing ≤15 designs/target yielded nanomolar binders on 6/9 for nanobodies (67%), mirrored by protein designs. We also show functional peptide designs (including disordered regions) and support for challenging modalities like disulfide-stabilized peptides and small-molecule binders.

The entire stack is open-source (MIT): weights, training & inference, and a full design pipeline.

@PetarV_93 Great explanation @PetarV_93 That paper is interesting but IMO the situation considered is a bit constrained. In practice, good features are all you need for message passing GNNs to solve DP etc

[Keyulu Xu @KeyuluXu]

@aoaXBT Thank you in advance 🥺

Our paper shows neural networks can learn surprisingly good representations with noisy labels. Pre-training and fine tuning with a good architecture structure is the key #Neurips2021

3/3 GNNs are vulnerable to information leakage attacks on social networks etc. We propose GAL with minimax games to protect the sensitive information.

2/3 We evaluate and understand what normalization methods work the best for GNNs. Our GraphNorm consistently improves the training and generalization of GNNs.

1/3 GNNs are implicitly accelerated by skip connections and more depth. We also show gradient descent training linearized GNNs converge to global minima.

[Keyulu Xu @KeyuluXu]

How do neural networks extrapolate, i.e., predict outside the training distribution? We study MLPs and Graph Neural Networks trained by gradient descent, and show how a good representation and architecture can help extrapolation.

ICLR's h5-index is 203 and ranks 17 among all scientific publication venues (ahead of NeurIPS, ICCV, ICML).

203 ICLR papers of the last 5 years have gathered more than 203 citations.

Pretty amazing for a conference that started in 2013.

学習したNNが学習分布外データの予測（外挿）をできるか。MLPは分布外では原点からの方向毎に線形になり、学習目標が非線形な場合は外挿できない。GNNは対象問題が動的計画法の形で解け、適切な非線形がアーキテクチャもしくは特徴に組み込まれている場合、外挿に成功する。https://t.co/6MjgX4YpVm
