遗忘

In order to upgrade the prediction precision, a forgetting factor is led in, which contributes to the direct modifications of TVP and the indirect prediction results.

遗忘因子的作用是直接修正时变参数，从而间接修正预测结果，达到提高预测精度的目的。

Among the tweedle of hundreds of birds, a group of supernatural wood-fairies appears, far and near, fixating you as if stealing the long forgotten secrets from your eyes.

在清脆的百鸟鸣叫声中，神奇的树精灵受到召唤，隐约出现在森林的每个角落，聚精会神地注视着你，像是要从你的眼中窃取你遗忘已久的秘密。

The memory is sometimes so retentive, so serviceable, so obedient; at others, so bewildered and so weak; and at others again, so tyrannic, so beyond control!

我们人各方面都堪称奇妙——但记忆力和遗忘力尤为奇妙无比。四月是最残忍的一个月，荒地上

People living in tyranny need to know they are not forgotten.

生活在暴政下的人民需要知道他们没有被遗忘。

An una cc eptable love needs no sorrow but time- sometime for forgetting. A

一段不被接受的爱情，需要的不是伤心，而是时间，一段可以用来遗忘的时间。

He must have left it somewhere unawares.

他一定是不小心把它遗忘在什么地方了。

When love become unbearable pain, memory chooses to forget.

当爱变为无法承受的痛苦，记忆选择遗忘

To individual, they are often unbeknown, are lost, their work are nonsensical, meaningless, even are false.

就个人而言，他们常常不为人知，被人们遗忘，他们的工作在今天看来，也许是无意义、无功劳，甚至是错误的。

In order to make the new recursive method convergence fast, the RLS-like forgetting factor is introduced to construct the new data Hankel matrices. In the framework of subspace methods, the gradient type subspace tracking method is used to implement the update of the state subspace, which results the unbiased estimate. Different from traditional offline method, the system matrices are recursively computed using RLS method. The convergence analysis of the proposed method is given and finally, the efficiency of this method is illustrated with a simulation example.A new closed-loop identification method is proposed to implement consistency estimation of closed-loop subspace identification.

引入RLS-like遗忘因子机制构造新的数据矩阵，更好地跟踪系统时变信息，提高递推算法的收敛速度；在子空间辨识框架内，采用梯度型子空间跟踪算法实现对状态子空间的更新，避免了子空间近似带来的估计有偏性；与传统的离线算法不同，在得到系统状态子空间后，基于递推最小二乘方法提出新的算法，实现对系统矩阵的递推估计；并给出递推子空间辨识算法的收敛性分析；最后通过仿真实例验证算法的有效性。

The government badly wanted this last foot-soldier to be memorialised; but he preferred to be uncelebrated and ordinary, even in some sense forgotten, and thus the more symbolic of all the rest.

政府想要纪念这位最后的步兵；但是，蒙蒂塞利喜欢的是默默无闻，简简单单，甚至是被遗忘，这样才更像他的战友们。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
