Identifying Visible Actions in Lifestyle Vlogs (P19-1)
Copied to clipboard
| Challenge: | Existing methods for identifying human actions in videos are limited by the number of visual depictions in the videos. |
| Approach: | They propose a multimodal algorithm that leverages visual and linguistic clues to automatically infer which actions are visible in a video. |
| Outcome: | The proposed algorithm can identify actions visible in video while verbally describing them. |
Analyzing the Surprising Variability in Word Embedding Stability Across Languages (2021.emnlp-main)
Copied to clipboard
| Challenge: | Word embeddings are powerful representations that form the foundation of many natural language processing architectures. |
| Approach: | They explore word embedding stability in a wide range of languages to gain insight into their stability. |
| Outcome: | The proposed results provide insights into word embedding stability in English and other languages. |
Using Paraphrases to Study Properties of Contextual Embeddings (2022.naacl-main)
Copied to clipboard
| Challenge: | Previously, paraphrases have been used to probe whether compositionality is accurately captured by BERT, but we believe they can be used to explore many other questions. |
| Approach: | They propose to use paraphrases as a unique source of data to analyze contextualized embeddings, with a particular focus on BERT. |
| Outcome: | The proposed analysis of paraphrases and paraphrase representations using the Paraphrase Database shows that BERT handles polysemous words, but different representations in many cases. |
