sample path

the model admits an efficient calculation of the sample path gradient of the network revenue function. the gradient is then used to construct a stochastic steepest ascent algorithm.

该模型对网络收益函数的样本梯度进行了有效的计算，并将梯度应用于构建随机最陡上升算法。

Based on the separation work of continuous sample path variance and discrete jump variance, heterogeneous autoregressive ( HAR) model is used here for volatility modeling and forecasting.

在将波动率当中的连续样本路径方差和离散跳跃方差有效地分离开后，文章选用异质自回归类（HAR）模型来对波动率建模预测。

Different from the traditional computation-based approaches, this algorithm could estimate the gradients of performance with respect to the policy parameters by simulating a single sample path, and look for an optimal ( or suboptimal) randomized stationary policy.

不同于传统的基于计算的方法，文中的算法是根据单个样本轨道的仿真来估计性能指标关于策略参数的梯度，以寻找最优（或次优）随机平稳策略。

In financial mathematics, a series of stock prices is regarded as a sample path of stochastic process. Thus the realization of these stock prices is only an event with zero probability.

在金融数学里，股价只被看成是一个随机过程的一根样本轨道，这样一只股票的一组股价的实现只是一个零概率事件，分析起来当然也就毫无意义。
