摘要:

在本文中,我们测试了几个稀疏优化算法的基础上的DREAM5基因调控网络推理挑战赛的公共数据集。研究发现,引入20%的调控网络作为先验已知数据,可以为推理算法的参数选择提供依据,从而提高预测效率和精度。除了测试常见的稀疏优化方法外,我们还通过将它们装袋来开发投票算法。在DREAM5数据集上的实验表明,基于稀疏优化的适度关系推理效果良好,在三个数据集上取得了比官方DREAM5结果更好的结果。然而,传统的独立算法的性能在面对不同的数据集时差异很大,而我们的投票算法在四个数据集中的三个上取得了最好的结果。

英文摘要:

In this paper, we tested several sparse optimization algorithms based on the public dataset of the DREAM5 Gene Regulatory Network Inference Challenge. And we find that introducing 20% of the regulatory network as a priori known data can provide a basis for parameter selection of inference algorithms, thus improving prediction efficiency and accuracy. In addition to testing common sparse optimization methods, we also developed voting algorithms by bagging them. Experiments on the DREAM5 dataset show that the sparse optimization-based inference of the moderation relation works well, achieving better results than the official DREAM5 results on three datasets. However, the performance of traditional independent algorithms varies greatly in the face of different datasets, while our voting algorithm achieves the best results on three of the four datasets.
