An alternative to the hierarchical softmax is Noise Contrastive According to the original description of the Skip-gram model, published as a conference paper titled Distributed Representations of Words and Phrases and their Compositionality, the objective of this model is to maximize the average log-probability of the context words occurring around the input word over the entire vocabulary: (1) Mnih, Andriy and Hinton, Geoffrey E.
