How LSTM Encodes Syntax: Exploring Context Vectors and Semi-Quantization on Natural Text (2020.coling-main)
Copied to clipboard
| Challenge: | LSTMs are widely used to capture informative long-term syntactic dependencies, but how they are reflected in their internal vectors for natural text has not been adequately investigated. |
| Approach: | They analyze how syntactic dependencies are reflected in LSTM's internal gates by learning a language model where syntaktic structures are implicitly given. |
| Outcome: | The proposed model can predict whether a word is inside a phrase structure or not from a small number of components of the context-update vector. |
