To apply normalization, you will import StandardScaler module from the sklearn library and select only the features from the breast_dataset you created in the Data Exploration step. Once you have the features, you will then apply scaling by doing fit_transform on the feature data. While applying...

Machine learning methods excel in identifying patterns and regularities from large datasets. For example, Jiang et al. [29] demonstrated the effective application of SVM in predicting the MDA. Chen et al. [30] proposed the DRMDA model, which combines SVM and autoencoder (AE) for association p...
Consider that timestep to be the conclusion of the action for that body part t. Take the smallest of the preceding step’s action starts. Subtract 250 timesteps, which marks the activity as a whole beginning. Assume this; take the maximum value from the action endpoints identified in the ...

Different countries have parts of their higher education systems in which they excel, and there is an opportunity for international exchange in education to play a more significant role in the current development of higher education. Educators from different countries can understand and learn from each...
\small \begin{cases} X_{正指标}=\frac{X_{ij}-\min X_j }{\max X_j-\min X_j}\\ X_{负指标}=\frac{\max X_j-X_{ij}}{\max X_j-\min X_j} \end{cases}\in\{0,1\}\\然后就是根据信息熵的定义确定权重(论文《A mathematical theory of communication》)[2]。
