We're getting ready for Maustag 2025 www.mdsi.tum.de/en/mdsi/late... at the @tum.de Munich Data Science Institute, where we @daisybio.de plan to show children why AI and bioinformatics are important for studying the code of life. I dare say that our first practice session went quite well :-)

I enjoyed visiting the BC2 conference: cool talks,
great networking, beautiful location. Thanks to the organizers at @sib.swiss I appreciated especially today's session on startups in bioinformatics, that was insightful.

Our benchmark + guidelines for atlas-level differential gene expression of single cells is online:

Bottom line: Use pseudobulk + DESeq2 in simple and pseudobulk + DREAM in more complex settings.

🧬🖥️Drug response prediction is a machine learning challenge with immense potential for precision medicine. Our latest preprint introduces DrEval, a comprehensive benchmarking framework to evaluate state-of-the-art methods, uncover widespread issues, and guide the development of more robust models.
judith-bernett.bsky.social Judith Bernett @judith-bernett.bsky.social · Jun 3
🧬🖥️So excited to show you the outcome of @pascivers.bsky.social and my latest project: "From Hype to Health Check: Critical Evaluation of Drug Response Prediction Models with DrEval" doi.org/10.1101/2025.05.26.655288, published with M. Picciani, M. Wilhelm, K. Baum & @itisalist.bsky.social.
🧵1/10
Overview of the DrEval framework. Via input options, implemented state-of-the-art models can be compared against baselines of varying complexity. We address obstacles to progress in the field at each point in our pipeline: Our framework is available on PyPI and nf-core and we follow FAIReR standards for optimal reproducibility. DrEval is easily extendable as demonstrated here with a pseudocode implementation of a proteomics-based random forest. Custom viability data can be preprocessed with CurveCurator, leading to more consistent data and metrics. DrEval supports five widely used datasets with application-aware train/test splits that enable detecting weak generalization. Models are free to use provided or custom cell line– and drug features. The pipeline supports randomization-based ablation studies and performs robust hyperparameter tuning for all models. Evaluation is conducted using meaningful, bias-resistant metrics to avoid inflated results from artifacts such as Simpson’s paradox. All results are compiled into an interactive HTML report. Created in https://BioRender.com.

Traveling to Innsbruck by invitation of @francescafinotello.bsky.social to talk about data leakage, a widespread issue in biomedical machine learning applications. I'll talk about challenges in protein-protein interaction (doi.org/10.1093/bib/...) and drug response prediction (upcoming preprint!).
Colorful liquid flowing from one bottle into another, as an illustration for (data) leakage.

We followed up on our previous work, where we showed that predicting protein-protein interactions from sequence alone yields random performance when data leakage is accounted for. In this new preprint, we show that ESM2 embeddings raise the bar to 0.65 accuracy independent of the model architecture.

🧬🖥️ Proud to share our latest update on PPI predictions – "Deep learning models for unbiased sequence-based PPI prediction plateau at an accuracy of 0.65" doi.org/10.1101/2025... by T. Reim, published with @itisalist.bsky.social @dbblumenthal.bsky.social, A. Hartebrodt, and me. What did we do? 1/15 🧵
Graphical summary of the analyses done in the publication displayed on six panels a-f. (a) We computed ESM-2 embeddings of different sizes for the proteins of our data-leakage-free PPI dataset. The per-token embeddings have variable sizes depending on the protein length, while the per-protein embeddings have a fixed size by applying dimension-wise averaging. (b) We tested two models operating on the per-protein embeddings—a baseline random forest classifier and adaptions of the previously published Richoux model. Five models operated on the per-token embeddings: a 2d-baseline, the 2d-Selfattention and 2d-Crossattention models (which expanded the 2d-baseline through a Transformer encoder), and adaptations of the published models D-SCRIPT and TUnA. (c) Hyperparameter tuning gave us insight into the influence of each tunable parameter on the classification performance. (d) No model surpassed an accuracy of 0.65. The more advanced models had similar accuracies, leading us to believe that the information content of the ESM-2 embedding has more influence than the model architecture. Per-token models did not consistently outperform per-protein models. (e) We applied various modifications to test their influence: different embedding sizes, inserting a Transformer encoder into different positions, adding spectral normalization after the linear layers, self- vs. cross-attention, and removing the padding. (f) Finally, we compared the implicitly predicted distance maps of the 2d-baseline, 2d-Selfattention, 2dCrossattention, and D-SCRIPT-ESM-2 to real distance maps computed from PDB structures.
