forward inference meaning in English
前向推理 [向前推理
Examples
- Relationship between forward inference versus backward inference and predict in chinese text comprehension
中文故事阅读中预期与前后向推理的关系 - The forward inference algorithm starts from existing facts while the backward inference starts from result fact
基于ann的知识库，论文提出了两种不同的推理算法。 - Based on an analysis about the construction of soccer game , a decision making expert system with forward inference is proposed , which the inference is in layers and the knowledge is in classes
在分析了机器人足球系统结构的基础上，利用专家系统的正向链接推理机制，提出了一个具有推理分层、知识分类的决策专家子系统。 - Secondly , this paper discuss basic conception and general structure of expert system mainly , analyzes merits and faults of some algorithm deeply , on the basis of that , presents a fan fault diagnosis expert system based on rough sets theory by field reality . with the relation of fan ’ s symptom and fault , structures symptom - fault parallel table which is simple and clear . reduces knowledge base by rough sets , establishes inference rules through forward inference , overcomes the “ bottle neck ” problem of knowledge acquisition of expert system by combining fuzzy theory with rough sets
然后着重论述了专家系统的基本概念和一般结构,介绍了粗糙集理论的研究基础以及在故障诊断中的应用,深入分析了几种算法的优缺点,在此基础上结合现场实际构建了基于粗糙集的风机故障诊断专家系统的体系结构。利用风机征兆和故障之间的关系构造了征兆故障对照表,关系简单明了。 - Procreant knowledge expression and forward inference engine are adopted in the method of fault diagnosis based on expert system theory . in the fault diagnosis applying neural network theory , six kinds of improved arithmetic of back - propagation arithmetic , including gradient descent with momentum , variable learning rate back - propagation , resilient back - propagation , quasi - newton , levenberg - marquardt and conjugate gradient , are applied to diagnose the faults of electric load manage center and solid state power controller . different diagnostic results gotten by simulation are compared at last
在基于专家系统的故障诊断方法中，采用了产生式知识表达和正向推理机制；在基于神经网络的故障诊断方法中，则分别采用了bp神经网络的附加动量法、自适应学习速率、弹性bp算法、拟牛顿法、共轭梯度法和levenberg - marquardt法对电气负载管理中心和固态功率控制器的故障进行诊断，并对由仿真得到的不同诊断结果进行比较。
