This project seeks to develop computationally efficient and scalable Bayesian algorithms to estimate the parameters of complex models and ensure inferences drawn from the models can be trusted. Bayesian parameter estimation and model validation procedures are currently computationally intractable for many complex models of interest in science and technology. These include biological processes such as the efficacy of heart disease, wound healing and skin cancer treatments. Potential outcomes of the project include new algorithms to significantly economise computations and improved understanding of the mechanisms of experimental data generation. Improved models of wound healing, skin cancer growth and heart physiology supported by these algorithms could improve population health.

该项目旨在开发计算高效且可扩展的贝叶斯算法来估计复杂模型的参数，并确保从模型中得出的推论是可信的。贝叶斯参数估计和模型验证程序目前对于许多科学和技术感兴趣的复杂模型来说在计算上是困难的。这些包括生物过程，如心脏病的疗效，伤口愈合和皮肤癌治疗。该项目的潜在成果包括显著节省计算的新算法，以及对实验数据生成机制的更好理解。由这些算法支持的伤口愈合、皮肤癌生长和心脏生理学的改进模型可以改善人口健康。
