Loss in Translation: Learning Bilingual Word Mapping with a Retrieval Criterion (D18-1)
Copied to clipboard
| Challenge: | Existing approaches to learn orthogonal matrix aligning bilingual lexicons are suboptimal . resulting models suffer from "hubness problem" because word vectors tend to be nearest neighbors of abnormally high number of other words. |
| Approach: | They propose a unified formulation that directly optimizes a retrieval criterion in an end-to-end fashion. |
| Outcome: | The proposed approach outperforms the state-of-the-art on word translation on standard benchmarks. |
Learning Word Vectors for 157 Languages (L18-1)

| Challenge: | Distributed word representations, or word vectors, have been used in natural language processing for many tasks. |
| Approach: | They propose to use the encyclopedia Wikipedia and the common crawl corpus to train distributed word representations on large corpora and use them in downstream tasks. |
| Outcome: | The proposed model performs very well on 10 languages for which evaluation dataset exists. |
Advances in Pre-Training Distributed Word Representations (L18-1)
Copied to clipboard
| Challenge: | Pre-trained word representations are a building block of many Natural Language Processing and Machine Learning applications. |
| Approach: | They propose to combine known tricks and a set of publicly available pre-trained word vector representations to train high-quality representations. |
| Outcome: | The proposed models outperform the current state of the art on a number of tasks while maintaining a high training speed to scale to massive amount of data. |
