autoencoder is then tested for association with survival using univariate Cox-PH models. The features significantly associated with survival are then subject to clustering (Gaussian clustering by default). Upon determining the optimal cluster, the top features in each omic input data type are selected...
Thus, the image representation in the distorted feature space will hurt the clustering performance. To overcome the problems of DAC, we present an image clustering representation learning method based on autoencoder (AE) [21] and deep adaptive image clustering (DAC) [20]. Specifically, to obtain...
