    A differentiable Gillespie algorithm for simulating chemical kinetics, parameter estimation, and designing synthetic biological circuits

    Krishna Rijal, Pankaj Mehta
    A differentiable variant of the Gillespie algorithm enables gradient-based optimization for stochastic chemical kinetics, facilitating efficient parameter estimation and the design of biochemical networks with desired input–output relationships.

    Flexible and efficient simulation-based inference for models of decision-making

    Jan Boelts, Jan-Matthis Lueckmann ... Jakob H Macke
    A new machine learning method makes it possible to efficiently identify the parameters of cognitive models using Bayesian inference, even when only model simulations are available.

    Quantifying how post-transcriptional noise and gene copy number variation bias transcriptional parameter inference from mRNA distributions

    Xiaoming Fu, Heta P Patel ... Ramon Grima
    A combined experimental and modeling approach provides insight into potential biases when inferring transcription rates from static mRNA distributions, and shows that correcting for cell-cycle phase and post-transcriptional noise provides rates that agree with live-cell transcription measurements.

    Likelihood approximation networks (LANs) for fast inference of simulation models in cognitive neuroscience

    Alexander Fengler, Lakshmi N Govindarajan ... Michael J Frank
    A novel method and software provides researchers with the capability to rapidly, flexibly, and robustly perform Bayesian parameter estimation of theoretically meaningful models in cognitive neuroscience that were heretofore intractable.

    Leave-One-Trial-Out, LOTO, a general approach to link single-trial parameters of cognitive models to neural data

    Sebastian Gluth, Nachshon Meiran
    Leave-One-Trial-Out (LOTO) is a general, efficient and easily implementable approach for inferring trial-by-trial measures of computational model parameters in order to link these measures to neural mechanisms.

    Introducing µGUIDE for quantitative imaging via generalized uncertainty-driven inference using deep learning

    Maëliss Jallais, Marco Palombo
    µGUIDE is a Bayesian framework that leverages simulation-based inference to efficiently estimate posterior distributions of any forward model parameters, allowing for uncertainty quantification and degeneracy detection.

    Robust and Efficient Assessment of Potency (REAP) as a quantitative tool for dose-response curve estimation

    Shouhao Zhou, Xinyi Liu ... J Jack Lee
    A novel approach together with a user-friendly web-based analytic tool, coined 'REAP', was proposed to improve the quantitative assessment of dose-response relationship and drug potency.

    The Mutationathon highlights the importance of reaching standardization in estimates of pedigree-based germline mutation rates

    Lucie A Bergeron, Søren Besenbacher ... Mikkel H Schierup
    This first comparison of different methodologies to estimate germline mutation rate from pedigrees resulted in almost a 2-fold variation in the estimated rates, discrepancies mainly caused by different filtering methods.

    Cortical state transitions and stimulus response evolve along stiff and sloppy parameter dimensions, respectively

    Adrian Ponce-Alvarez, Gabriela Mochol ... Gustavo Deco
    Neurons differ in their impact on collective cortical activity, with sensitive neurons forming a stable topological core, implicated in cortical-state transitions, while peripheral insensitive neurons are more responsive to stimuli.
