You’ll explore vector graphics and sound frequency analysis, but complex numbers can also help in drawing fractals, such as the Mandelbrot set.In this tutorial, you’ll learn how to:Define complex numbers with
NumPy 的Generator类上的exponential方法需要一个scale参数,这是1/λ,其中λ是速率。我们选择速率为 4,并创建 50 个样本到达时间间隔: 代码语言:javascript 代码运行次数:0 运行 复制 rate = 4.0 inter_arrival_times = rng.exponential(scale=1./rate, size=50) 接下来,我们使用 NumPy 的add通用函数的accumulate...
我们的第一个任务是通过从指数分布中抽样数据来创建样本到达时间间隔。NumPy 的Generator类上的exponential方法需要一个scale参数,这是1/λ,其中λ是速率。我们选择速率为 4,并创建 50 个样本到达时间间隔: rate =4.0inter_arrival_times = rng.exponential(scale=1./rate, size=50) 接下来,我们使用 NumPy 的add...

在前面的章节中,我们学习了强化学习(RL)的基本概念和几种 RL 算法,以及如何将 RL 问题建模为马尔可夫决策过程(MDP)。 我们还看到了用于解决 MDP 的不同的基于模型和无模型的算法。 在本章中,我们将看到 RL 中的经典问题之一,称为多臂老虎机(MAB)问题。 我们将看到什么是 MAB 问题,以及如何使用不同的算法解...

We could solve this with dependency injection, as we had before—the caller would be responsible for setting up theTurtleobject. But what if our function sometimes needs to make many turtles for different drawing purposes, or if perhaps it wants to kick off four threads, each with its own ...
With the External Axes Method creating charts is more or less similar to what we have done so far. Mplfinance takes care of drawing the OHLC or candlesticks charts. We can then pass an Axes object with our indicator as a separate subplot. 使用“ 外部轴方法”创建图表与我们到目前为止所做的...
The above drawing is the 6 coordinate points that are combined using X and Y matrices. The above two-dimensional arrays of X and Y are manually input. If there are a large number of points on the coordinates, manual input is definitely not advisable. ...
