Model, take the wheel! Part II: multi-fidelity, cost-aware active learning

We extend our previous active learning analysis to choose not just which compound to test, but which assay to run. Utilizing both primary screens and full dose-response measurements cuts the cost of finding actives by more than half, without costing the model any accuracy.

Blind Challenges

It’s the End of the PXR Challenge as We Know It (and I feel fine)

Announcing the results of the PXR Blind Challenge — and the public release of the largest high-quality PXR induction dataset ever made available, with over 11,000 compounds.

Not invited to the party? How to make proprietary ADMET insights more accessible

How do you train robust deep learning models when most of the high-quality data is proprietary? Discover how to enrich multitask ADMET predictions using a public proxy for proprietary learnings.

Cofolding? I hardly know her! - Cofolding Methods on ADMET Targets

Part 1 of a series on cofolding methods for ADMET targets: using structure prediction to model protein–ligand complexes for key Avoidome anti-targets like PXR and CYP3A4.

Blind Challenges

Woah, we’re halfway there…

We're halfway through the PXR Blind Challenge: unblinding the first data, freezing the leaderboard, and stepping into Phase 2 — plus a look at the response so far and what's next.

Data

Navigating PXR Chemical Space with High-Throughput Chemistry and Standard-Free Quantification

With Octant, we use direct-to-biology high-throughput chemistry and standard-free quantification to explore PXR chemical space far beyond commercial libraries, part of OpenADMET's effort to map the Avoidome.

Model, take the wheel: active learning with pEC50 data

Synthesizing and assaying compounds is slow and costly. Sean Colby explores whether active learning can use what a model already knows to guide which pEC50 data to acquire next.

Blind Challenges

Peak Performance or Just Noise?

Benchmarks are everywhere in ML — but when is a leaderboard gap real? Jon Swain on the statistics of comparing blind challenge entries and separating genuine performance from noise.
