To ensure that only the faces and not the use of a certain background or a certain set of clothes are biasing our results, we used the dlib library implemented in Python to locate and crop the face. In addition we used the Python OpenFace library22 to align the images such that faces ...

where λ is the regularization parameter that controls the overall strength of the regularization, α is the mixing parameter that controls the balance between L1 and L2 regularization with α values closer to zero to result in sparser models (lasso regression α = 1, ridge regression α ...
When deciding whether to use theRegressionSVM Predictblock in the Statistics and Machine Learning Toolbox™ library or a MATLAB Function block with thepredictfunction, consider the following: If you use the Statistics and Machine Learning Toolbox library block, you can use theFixed-Point Tool(Fix...
与R中同样使用Python的先前示例类似,我们将使用Keras作为创建神经网络的关键包。我们还需要安装tensorflow并reticulate运行我们的模型。Keras的使用允许在两种编码语言之间的编码中使用非常相似的样式。 library(keras)library(tensorflow)library(reticulate)library(kerasR) ...
