- [1902.05196v1] Categorical Metadata Representation for Customized Text Classification (2019)
*(About)*

> We observe that current representation methods for categorical metadata... are not as effective as claimed in popular classification methods, outperformed even by simple concatenation of categorical features in the final layer of the sentence encoder. We conjecture that categorical features are harder to represent for machine use, as available context only indirectly describes the category

2019-02-18 - Entity Embeddings of Categorical Variables (2016)
*(About)*

> We map categorical variables in a function approximation problem into Euclidean spaces, which are the entity embeddings of the categorical variables. The mapping is learned by a neural network during the standard supervised training process. Entity embedding not only reduces memory usage and speeds up neural networks compared with one-hot encoding, but more importantly by mapping similar values close to each other in the embedding space it reveals the intrinsic properties of the categorical variables
