| Challenge: | InstaMap is a non-parametric model that learns a global linear projection by iterating between finding an optimal rotation of the source embedding space and moving each point along an instance-specific translation vector. |
| Approach: | They propose a non-parametric model that learns a global linear projection by iteratively finding an optimal rotation of the source embedding space and moving each point along an instance-specific translation vector. |
| Outcome: | The proposed model performs better than previous models on bilingual lexicon induction across a set of 28 diverse language pairs. |
