In natural language processing, a word embedding is a representation of a word. The embedding is used in text analysis.Typically, the representation is a real-valued vector that encodes the meaning of the word in such a way that the words that are closer in the vector space are expected to be similar in meaning. [1]
Arora et al. (2016) [25] explain word2vec and related algorithms as performing inference for a simple generative model for text, which involves a random walk generation process based upon loglinear topic model. They use this to explain some properties of word embeddings, including their use to solve analogies.
Unlike previous models, BERT is a deeply bidirectional, unsupervised language representation, pre-trained using only a plain text corpus. Context-free models such as word2vec or GloVe generate a single word embedding representation for each word in the vocabulary, whereas BERT takes into account the context for each occurrence of a given word ...
ELMo (embeddings from language model) is a word embedding method for representing a sequence of words as a corresponding sequence of vectors. [1] It was created by researchers at the Allen Institute for Artificial Intelligence , [ 2 ] and University of Washington and first released in February, 2018.
In practice however, BERT's sentence embedding with the [CLS] token achieves poor performance, often worse than simply averaging non-contextual word embeddings. SBERT later achieved superior sentence embedding performance [8] by fine tuning BERT's [CLS] token embeddings through the usage of a siamese neural network architecture on the SNLI dataset.
Object Linking and Embedding (OLE) is a proprietary technology developed by Microsoft that allows embedding and linking to documents and other objects. For developers, it brought OLE Control Extension (OCX), a way to develop and use custom user interface elements.
There are three Microsoft Office applications (Excel, PowerPoint, Word) not available through Imagine. However, Office Home & Student 2013 or Office 365 University offers those at a discounted price for students. Unlike the programs listed above, there is no way to access similar older and compatible versions (2010, 2007) of Office for Word ...
Table summary of the memory complexity and the link prediction accuracy of the knowledge graph embedding models according to Rossi et al. [5] in terms of Hits@10, MR, and MRR. Best results on each metric for each dataset are in bold. Model name Memory complexity FB15K (Hits@10) FB15K (MR) FB15K (MRR) FB15K - 237 (Hits@10) FB15K - 237 (MR)
