Visual features representation. (a) Cosine distance of graphical digital objects between items grouped by collections and categories (coloured bands on the right), recognising aesthetical similarities and uniformity between and within these groups. For visualization purposes, we selected the largest 98 collections in our dataset. (b) The dimensionality reduction of AlexNet vectors by PCA and their visualization in the PC1, PC2 and PC3 space, broken down by NFT categories, demonstrate the presence of graphically uniform clusters. For visualization purposes, we downsampled the digital objects associated with the CryptoKitties and Sorare collections, which alone constitute the 61% of the whole dataset.
