查询词典 expectation

However, via intensive numerical computation, the author finds that actually some characteristic of this confidence intervals, for example, confidence coefficient, expectation width and coverage efficiency fluctuate intensely when the sample size varies given the parameter, or when the parameter varies given the sample size.

In this paper, the computation of original likelihood function is transformed into the optimal problem of its low bound through the conjugate representation of the convex function, and a additional parameter is introduced to control the smoothing degree of low bound, and so the performance of local optimal solution can be improved.

我们利用凸泛函的对偶性，将原似然函数的复杂计算问题转化为对其下界函数的优化问题，从而降低学习算法的复杂性；并通过引入一个参数来控制下界函数的光滑程度来改善局部最优解的性能；指出了传统的期望最大化算法(Expectation Maximization Algorithm)是变分学习算法的特殊情况。

To satisfy such social needs, English grammar teaching should shift from tradition, which regards grammar as an isolated, context-free and sentence-based language system, to present-day grammar teaching, which matches form with meaning and function in context, with the expectation of helping learners to achieve their ultimate goal, i.e. to use language appropriately, accurately and fluently in real communication.

为培养这样的人才，英语专业的语法教学应摆脱传统教学法的束缚，把语法与意义和功能结合起来，在一定的语境中去探讨学习语法，以期培养学生的交际能力，达到最终的目标，利用语言在实际的语境下自由、恰当、准确地表达思想，而语境语法教学可能成为实现这一目标的有意尝试。
