Listener Model for the PhotoBook Referential Game with CLIPScores as Implicit Reference Chain (2023.acl-short)
Copied to clipboard
| Challenge: | PhotoBook is a collaborative dialogue game where two players receive private, partially-overlapping sets of images and resolve which images they have in common. |
| Approach: | They propose a reference chain-free listener model that directly addresses the game’s predictive task, i.e., deciding whether an image is shared with partner. |
| Outcome: | The proposed model outperforms baseline models by >17 points on unseen images/game themes. |

The PhotoBook Dataset: Building Common Ground through Visually-Grounded Dialogue (P19-1)
Copied to clipboard
| Challenge: | Using the PhotoBook dataset, we investigate shared dialogue history accumulating during conversation . human interlocutors are known to collaboratively establish a shared repository of mutual information during a conversation - this common ground is then used to optimise understanding and communication efficiency. |
| Approach: | They propose a data-collection task formulated as a collaborative game prompting two online participants to refer to images utilising both their visual context and previously established referring expressions. |
| Outcome: | The proposed model takes into account shared information accumulated in a reference chain and is important to resolve later descriptions. |

CLIPScore: A Reference-free Evaluation Metric for Image Captioning (2021.emnlp-main)
Copied to clipboard
| Challenge: | Image captioning relies on reference-based automatic evaluations, but references are expensive to collect and comparing against multiple human-authored captions is insufficient. |
| Approach: | They propose a reference-free metric that can be used for automatic caption evaluation without references. |
| Outcome: | The proposed model outperforms existing metrics on image-text compatibility and a reference-augmented version achieves even higher correlation with human judgements. |
Pragmatic Inference with a CLIP Listener for Contrastive Captioning (2023.findings-acl)
Copied to clipboard
| Challenge: | a new method for contrastive captioning generates discriminative captions that distinguish target images from very similar alternative distractor images. |
| Approach: | They propose a pragmatic inference procedure that formulates captioning as a reference game between a speaker and a listener. |
| Outcome: | The proposed method outperforms previous methods for discriminative captioning by 11% to 15% accuracy in human evaluations. |
Collecting Visually-Grounded Dialogue with A Game Of Sorts (2022.lrec-1)

| Challenge: | Using a structured referent grounding module, we can effectively ground and inform a partner's utterances to their own context. |
| Approach: | They propose a grounded neural dialogue model that works with people in a partially-observable reference game. |
| Outcome: | The proposed model outperforms state-of-the-art models on a spatial grounding dialogue task and achieves a 20% relative improvement in human evaluations. |
PhotoChat: A Human-Human Dialogue Dataset With Photo Sharing Behavior For Joint Image-Text Modeling (2021.acl-long)
Copied to clipboard
| Challenge: | PhotoChat contains 12k dialogues, each of which is paired with a user photo that is shared during the conversation. |
| Approach: | They propose to use PhotoChat to facilitate research on image-text modeling by combining a photo-sharing intent prediction task and a picture retrieval task to retrieve the most relevant photo according to the dialogue context. |
| Outcome: | The proposed tasks achieve 10.4% recall@1 and 58.1% F1 scores, indicating that the proposed dataset presents interesting yet challenging real-world problems. |
Know your audience: specializing grounded language models with listener subtraction (2023.eacl-main)
Copied to clipboard
| Challenge: | Effective communication requires adapting to the idiosyncrasies of each communicative context. |
| Approach: | They propose a method for specializing grounded language models without supervision . they fine-tune an attention-based adapter between a CLIP vision encoder and a large language model . |
| Outcome: | The proposed method allows a speaker to adapt to the idiosyncracies of the listeners without supervision. |
Learning to Relate from Captions and Bounding Boxes (P19-1)
Copied to clipboard
| Challenge: | Existing methods for classifying images without supervision are limited. |
| Approach: | They propose a top-down attention mechanism to align entities in captions to objects in the image and leverage the syntactic structure of captions for alignment. |
| Outcome: | The proposed model achieves a recall@50 of 15% and recall@100 of 25% on the relationships present in the image and predicts relations that are not present in captions. |
