In studying the interrelationship between sectors,forward linkage and backward linkage of Input-output analysis are generally used,while the result is the direct or complete relationship between one section and another,and the production chains linkage of multiple sectors are not highlighted.
利用投入产出技术的前向关联和后向关联方法可以分析某一部门与其它部门的直接或完全联系(或影响),却没有突出多个部门间的生产链联系。
The improved promoter prediction method is based on the forward algorithm of the Hidden Markov Model.
本文实现了基于马尔可夫模型的启动子预测算法,结合隐马尔可夫模型中的前向算法,改进了基于马尔可夫理论的启动子预测方法,具体改进了碱基转移概率的算法和序列所在模型的概率。
Prediction algorithm of biological genes was developed combining the forward algorithm with hidden Markov model(HMM) to identify protein coding regions from DNA sequences and improving calculation efficiency.
为更好地从DNA序列中识别蛋白质编码区,提高计算效率,将隐马尔科夫模型与前向算法相结合,提出一种生物基因的预测算法。
