Table 5. Multi-view clustering performance on handwritten digits.

The NMI and accuracy (ACC) values of multi-view clustering approaches, as they were presented by the authors in their corresponding articles, are depicted along the clustering performance of multi-SNE on a range of dimensions for the embeddings ( $d=2,3,5,10$). The performance of multi-SNE with PCA and multi-CCA are depicted in the table, with weight adjustments in both variations.
