ELMo: Deep contextualized word representations (2018) The main idea of the Embeddings from Language Models (ELMo) can be divided into two main tasks, first we train an LSTM-based language model on some corpus, and then we use the hidden states of the LSTM for each token to generate a vector representation of each word. Zhong et al. Our model consists of six parts, including (1) a hybrid representation layer that maps each word to a hybrid between character- and word-level embedding, (2) a contextualized representation layer that enhances the representation power of embeddings, (3) a matching layer that compares each token of one argument against all tokens of the other one and vice versa, (4) a fusion layer that assigns … Wen-Bin Han and Noriko Kando.

PEters ME, Neumann M, Iyyer M, Gardner M, Clark C, Lee K, and Zettlemoyer L (2018) Deep contextualized word representations. • Deep: The word representations combine all layers of a deep pre- trained neural network. Big changes are underway in the world of NLP. The long reign of word vectors as NLP's core representation technique has seen an exciting new line of challengers emerge. These approaches demonstrated that pretrained language models can achieve state-of-the-art results and herald a watershed moment. [4] Minmin Chen.

The 2018 NAACL Student Research Workshop (SRW) will be held in conjunction with NAACL HLT 2018 in New Orleans, Louisiana. • Character based: ELMo representations are purely character based, allowing the network to use morphological clues to form robust representations for out-of-vocabulary tokens unseen in training.

The integers themselves did not mean anything; the assignment might be arbitrary, alphabetical, or in the order word tokens were observed in a reference text corpus from which the vocabulary was derived (that is, the type of the first word token observed would get 0, the type of the second word token would get 1 if it was different from the first, and so on).

Matthew E. Peters, Mark Neumann, Mohit Iyyer, Matt Gardner, Christopher Clark, Kenton Lee and Luke Zettlemoyer. Unlike previous approaches for learning contextualized word vectors (Peters et al., 2017; McCann et al., 2017), ELMo representations are deep, in the sense that they are a function of all of the internal layers of the biLM. However, in many cases, the contextualized embedding of a word changes drastically when the context is paraphrased. [1] Learned in Translation: Contextualized Word Vectors; by McCann et al., NIPS 2017. Evaluation of pooling operations in convolutional architectures for object recognition. Besides the impressive empirical results, where it shines is the careful analysis section that teases out the impact of various factors and analyses the information captured in the representations.
