Efficient Sentence Embedding using Discrete Cosine Transform (D19-1)
Copied to clipboard
| Challenge: | Modern NLP systems rely on word embeddings as input units to encode statistical semantic and syntactic properties of words. |
| Approach: | They propose to use discrete cosine transform to compress word sequences in order-preserving manner. |
| Outcome: | The proposed model preserves syntactic information in semantic probing tasks . it is comparable to vector averaging but mediocre in performance. |
