"Identifying, Understanding, and Exploiting Semantics During Exact Inference in Discrete Bayesian Networks"

我的研究重点是贝叶斯网络，这是一个基于概率论的不确定性管理的正式框架。特别是对贝叶斯网络推理进行了研究。我们的研究计划可能会让我们更好地理解进化论。系统发育学领域提出了困难的统计和计算问题。在分子数据泛滥的情况下，为一些样本数据测试所有可能的进化树是不可行的。取而代之的是，只给可能的树的一部分打分。通过提供一种更有信息量和更有效的树木评分方法，我们的方法将在相同的时间内为更多的树木评分，可能包括更准确地反映物种进化的树木。因此，我们有理由预计，我们的系统，称为DataBayes，将提供比Mr Bayes更好的结果，无论是在精度还是效率方面，Mr Bayes是一个用于系统发育贝叶斯估计的标准程序。通过提供更好的进化树，我们的研究结果的影响可能是巨大的。

My research focuses on Bayesian networks, which are a formal framework for uncertainty management based on probability theory. In particular, I study Bayesian network inference. Our research program may lead to a better understanding of the theory of evolution. The field of phylogenetics presents difficult statistical and computational problems. Given the flood of molecular data, it is not feasible to test all possible evolutionary trees for some sample data. Instead, only a portion of possible trees are scored. By providing a more informative and efficient method for scoring trees, our approach will score more trees in the same amount of time, likely including trees that more accurately reflect the evolution of species. Hence, it is reasonable to expect that our system, called DataBayes, will provide better results, both in terms of accuracy and efficiency, than MrBayes, a standard program for the Bayesian estimation of phylogeny. By providing a better evolutionary tree, the impact of our research findings may be immense.
