- Simulation-free Structure Learning for Stochastic Population Dynamics
Noah El Rimawi-Fine, Adam Stecklov, Lucas Nelson, Mathieu Blanchette, Alexander Tong, Stephen Y. Zhang, Lazar Atanackovic · 23 septembre 2026
Modeling dynamical systems and unraveling their underlying structural dependencies is central to many domains in the natural sciences. Various physical systems, such as those arising in cell biology, are inherently high-dimensional and stochastic in nature, and admit only partial, noisy state measur…
- A Learning Algorithm for Threshold Boolean Networks with Prescribed Fixed Points
Gonzalo A. Ruz · 18 septembre 2026
We present a learning algorithm for inferring threshold Boolean networks (TBNs) with a prescribed set of fixed points. The proposed method employs a custom differentiable loss function that jointly enforces fixed point preservation, penalizes spurious attractors, encourages binary outputs, and promo…
- Fundamental Dynamical Units for Physics-Informed Structural Inference from Perturbation Time-Series in Networked Systems
Nima Nouri · 14 septembre 2026
In networked dynamical systems, the parameter of primary mechanistic interest is signed interaction structure. Recovering this structure from perturbation time-series data is a fundamental identification problem, compounded by three coupled obstacles: the combinatorial complexity of interaction arch…
- Testing when adaptive data acquisition can replace fixed measurement plans
Jia Bi, Samuel Pinilla, Chenyang Zhu · 12 août 2026
Learned rules select samples for follow-up measurements in high-throughput experiments. Predicted value does not justify replacing a fixed plan. We introduce the opportunity-aware protocol for authorizing learned measurement rules (Opal), which learns a rule from labelled data, fixes it before outco…
- Continuous surrogates versus threshold Boolean networks for modeling Arabidopsis ISR gene regulation
Gonzalo A. Ruz · 28 juillet 2026
Gene regulatory network modeling often requires balancing predictive accuracy and mechanistic interpretability. In this work, we compare continuous surrogate models and a discrete mechanistic model on the same \textit{Arabidopsis thaliana} induced systemic resistance (ISR) dataset, using both the ra…
- BRIDGE: Bottleneck-Aware Regulator-Set Inference and Diagnosis for Cooperative Gene Regulatory Recovery
Maryam Rahimimovassagh, Clayton Thomas Barham, Ivan Garibay, Niloofar Yousefi · 22 juillet 2026
Cooperative gene regulation often depends on groups of regulators acting jointly, but most gene regulatory network (GRN) inference methods output pairwise regulator-target rankings. We introduce Bottleneck-Aware Regulator-Set Inference and Diagnosis (BRIDGE), a framework for complete regulator-set r…
- Deep and Probabilistic Models for Gene Regulatory Network Inference
Claudia Skok Gibbs · 20 juillet 2026
Gene regulatory networks (GRNs) link transcription factor (TF) proteins to their target genes, yet reconstructing these networks from genome-wide data remains challenging under practical and methodological constraints. Many methods couple modeling assumptions to a specific inference procedure and re…
- A Self-Evolving Agentic System for Automated Generation and Execution of Biological Protocols

Autonomous wet-lab experimentation requires more than plausible protocol text: biological intent, quantitative procedures, device constraints and experimental feedback must remain aligned from protocol and SOP design to code and physical execution. We developed ProtoPilot, a self-evolving multi-agen…
- Reduction of Probabilistic Chemical Reaction Networks
Mauricio Montes, Gregoire Sergeant-Perthuis · 29 juin 2026
Programming adaptive behaviors at the cellular level is a long-standing goal that raises the question of how probabilistic computation can be implemented in biochemical systems. Chemical reaction networks (CRNs) provide such a substrate and have been shown to realize probabilistic models, including …
- Belief Acquisition as Stochastic Filtering
Dawei Chen, John Lloyd, Samuel Yang-Zhao, Kee Siong Ng · 10 juin 2026
This paper studies how belief acquisition can be accomplished using stochastic filtering. First, a theoretical foundation for empirical beliefs is outlined. Then stochastic filtering in this context is studied. The paper introduces factored conditional filters, new filtering algorithms for simultane…
- When Should an AI Scientist Stop? Verifiable Experiment Steering and Refusal for Autonomous Discovery
Neel Tushar Shah, Manglam Kartik · 9 juin 2026
We present CARTOGRAPH, a verification layer for AI scientists that couples unresolved-subspace experiment steering (select), explicit ambiguity closure (resolve), and residual-based library inadequacy detection (refuse). Under a local linear-Gaussian bridge, raw unresolved projection is the isotropi…
- A comprehensive evaluation of pretraining strategies for channel-agnostic contrastive self-supervision of biosignals
Thea Br\"usch, Mikkel N. Schmidt, Tommy S. Alstr{\o}m · 25 mai 2026
Contrastive learning yields impressive results for self-supervision in computer vision. The approach relies on the creation of positive pairs, something which is often achieved through augmentations. However, for multivariate time series effective augmentations can be difficult to design. Additional…
- Reading the Cell, Designing the Cure: Perturbation-Conditioned Molecular Diffusion for Function-Oriented Drug Design
Ziyu Xu, Zijian Zhang, Liang Wang, Zhiyuan Liu, Qiang Liu, Shu Wu, Liang Wang · 18 mai 2026
When reliable target structures are unavailable at scale or phenotypes arise from dysregulated pathways, transcriptomic perturbations provide a system-level functional readout for drug action. In this work, we formalize \emph{Transcriptome-based Drug Design (TBDD)} as a generative inverse problem: d…
- GenCircuit-RL: Reinforcement Learning from Hierarchical Verification for Genetic Circuit Design
Noah Flynn · 15 mai 2026
Genetic circuit design remains a laborious, expert-driven process despite decades of progress in synthetic biology. We study this problem through code generation: models produce Python code in pysbol3 to construct genetic circuits in the Synthetic Biology Open Language (SBOL), a formal representatio…
- CellScientist: Dual-Space Hierarchical Orchestration for Closed-Loop Refinement of Virtual Cell Models
Mengran Li, Bo Li, Jiaying Wang, Wenbin Xing, Yixuan Dong, Chengyang Zhang, Hongliang Zhang, Yuzhong Peng, Jinlin Wu, Bob Zhang, Bingo Wing-Kuen Ling, Fuji Yang, Zhen Lei, Jiebo Luo, Zelin Zang · 11 mai 2026
Virtual Cell Modeling (VCM) requires models that not only predict perturbation responses, but also support targeted revision when predictions fail. Current LLM-assisted modeling workflows face a refinement-routing problem: prediction discrepancies are observed through executable implementations, but…
- Sequential Design of Genetic Circuits Under Uncertainty With Reinforcement Learning
Michal Kobiela, Diego A. Oyarz\'un, Michael U. Gutmann · 8 mai 2026
The design of biological systems is hindered by uncertainty arising from both intrinsic stochasticity of biomolecular reactions and variability across laboratory or experimental conditions. In this work, we present a sequential framework to optimize genetic circuits under both forms of uncertainty. …
- BAss: Symbolic Reasoning in Abstract Dialectical Frameworks

- Quantifying Ranking Instability Across Evaluation Protocol Axes in Gene Regulatory Network Benchmarking
Ihor Kendiukhov · 5 mars 2026
Benchmark rankings are routinely used to justify scientific claims about method quality in gene regulatory network (GRN) inference, yet the stability of these rankings under plausible evaluation protocol choices is rarely examined. We present a systematic diagnostic framework for measuring ranking i…
- Exact Discrete Stochastic Simulation with Deep-Learning-Scale Gradient Optimization
Jose M. G. Vilar, Leonor Saiz · 24 février 2026
Exact stochastic simulation of continuous-time Markov chains (CTMCs) is essential when discreteness and noise drive system behavior, but the hard categorical event selection in Gillespie-type algorithms blocks gradient-based learning. We eliminate this constraint by decoupling forward simulation fro…
