A Probabilistic Model for Joint Learning of Word Embeddings from Texts and Images (D18-1)
Copied to clipboard
| Challenge: | Existing approaches combine language and perception to infer word embeddings . however, the embeddables produced by such models do not reflect the actual word representations. |
| Approach: | They propose a probabilistic model that integrates linguistic and perceptual inputs to explain observed word-context pairs in a text corpus. |
| Outcome: | The proposed model achieves competitive or stronger results on tasks of assessing pairwise word similarity and image/caption retrieval compared to other state-of-the-art models. |

Deep Generative Model for Joint Alignment and Word Representation (N18-1)

| Challenge: | EmbedAlign model embeds words in their complete observed context and learns by marginalisation of latent lexical alignments. |
| Approach: | They exploit translation as a distributional context and embed words as posterior probability densities, rather than point estimates, which allows them to compare words in context using a measure of overlap between distributions. |
| Outcome: | The proposed model performs on a range of lexical semantics tasks and achieves competitive results on benchmarks including natural language inference, paraphrasing, and text similarity. |

Improving Pre-trained Vision-and-Language Embeddings for Phrase Grounding (2021.emnlp-main)
Copied to clipboard
| Challenge: | Existing studies have focused on the phrase grounding ability of pretrained vision-and-language models, but it is unclear how they can be used for phrase ground. |
| Approach: | They propose to extract phrase-region pairs from pre-trained vision-and-language embeddings and propose four fine-tuning objectives to improve model phrase grounding ability using image-caption data without any supervised grounding signals. |
| Outcome: | The proposed model outperforms baseline models in weakly-supervised and supervised phrase grounding settings on two representative datasets and shows that it is possible to achieve better phrase groundability without sacrificing representation generality. |
