bounds_df['real_value'] = truth_uncertainty_plot_df['log_energy_consumption'] 尽管置信区间覆盖比例不理想,但贝叶斯LSTM在不确定性量化方面的尝试,为能耗预测等应用提供了更丰富的决策依据。例如在电力调度场景中,调度人员可结合预测值与置信区间,灵活安排发电计划,应对可能的能耗波动。
Notice that even though the number of characters is different between Real and Python, MATLAB is able to create the string array. On line 6 you are checking the size of the string array, which shows that there are 2 rows and 1 column, as expected....
Each plot, including the animated one (in yellow), can be panned and scaled in real-time with your cursor. If you’ve used Python GUI frameworks in the past, and in particular ones with free-form graphics, you would probably expect sluggish performance. This is not the case with ...
