首先,我们使用模型对测试集进行预测,得到预测结果y_pred。 然后,我们定义了一个名为plot_cm的函数,用于绘制混淆矩阵的可视化图像。该函数接受真实标签y_true、预测标签y_pred和类别名称class_names作为输入,利用Seaborn库中的heatmap函数绘制混淆矩阵,并通过调整图表的细节使其更加易于理解。 最后,我们调用plot_cm函数,...

This article introduces the use of matplotlib to draw different two-dimensional graphics. Basic drawing process:-Create the canvas-Add title, add X axis and Y axis name, modify the scale and range of X axis and Y axis-Draw graphics and adjust the graphic style-Add legend-Display picture af...

Easy to use Python API wrapper to plot charts with matplotlib, plotly, bokeh and more:chartpy creates a simple easy to use API to plot in a number of great Python chart libraries like plotly (via cufflinks), bokeh and matplotlib, with a unified interface. You simply need to change a sin...
The aim above is to be fulfilled by developing three different computer modelsin MATLAB or/and Simulink, one by each group member, and presenting and analysing thesimulation results. The final simulation results (intermediate ones may be used tostrengthen the quality of the essay, where deemed ap...
We use two scaling functions, scale_down and scale_up. The scale_down function subtracts a mean value and scales the input signal to be between -1 and 1. The scale_up function reverts the vector back to it’s original values so that calculations can be carried out normally on the ...
