| 摘 要： | 提出了一种小规模数据集下学习贝叶斯网络的有效算法—FCLBNo FCLBN利用bootstrap方法在给定的小样本数据集上进行重抽样，然后用在抽样后数据集上学到的贝叶斯网络来佑计原数据集上的贝叶斯网络的高置信度的特征，并用这些特征来指导在原数据集上的贝叶斯网络搜索。用标准的数据集验证了FCLBN的有效性，并将FCLBN应用于酵母菌细胞中蛋白质的定位预测。实验结果表明，FCLBN能够在小规模数据集上学到较好的网络模型。 |

| Abstract: | An efficient algorithm FCLBN for learning Bayesian network from small scale dataset was proposed. FCLBN uses the method of bootstrap to rcsample from the small scale dataset, and estimates the high confidence features of thesource small scale dataset from the Bayesian networks learned from the re-sampling small datasets. The high confidence features arc taken to guide the search of the best Baycsian network on the source dataset. After being evaluated on the standard benchmark dataset, FCLBN is applied to predict yeast protein localization. The result of the experiments indicafes that the FCLBN algorithm can learn relatively accurate network from small scale dataset. |
