AWhat changed
Combined averaged n-gram features with low-rank text classification and hierarchical softmax, and extended skip-gram vectors with hashed character n-gram composition for rare and unseen words.
Scientific scope
Combined averaged n-gram features with low-rank text classification and hierarchical softmax, and extended skip-gram vectors with hashed character n-gram composition for rare and unseen words. Two original papers with different first authors/order, retained as source-specific sets in one family. Inherits bag-of-words, hierarchical softmax, hashing and earlier character/morphological embeddings; not invention of them. Classification word n-grams and embedding character n-grams are different mechanisms. Original subword version includes word vectors and omits n-grams for selected frequent words.
Evidence
The linked original sources describe the stated contribution and its evidence limits. WRS has not independently rerun the experiments or certified a proof.
