X-LXMERT: Paint, Caption and Answer Questions with Multi-Modal Transformers (2020.emnlp-main)
Copied to clipboard
| Challenge: | Recent work has adapted vision-and-language models to generative tasks like image captioning. |
| Approach: | They propose an extension to LXMERT with training refinements to generate images from text. |
| Outcome: | The proposed model can generate images from pieces of text while still being comparable to existing models. |

| Challenge: | Communicating with humans is challenging for AIs because of its complexity and multimodality. |
| Approach: | They propose to use a game of drawing and guessing based on Pictionary to test AIs' understanding of the world and multi-modal gestures. |
| Outcome: | The proposed game is a test for mixing language and visual/symbolic communication in AI. |
PIGLeT: Language Grounding Through Neuro-Symbolic Interaction in a 3D World (2021.acl-long)

| Challenge: | PIGLeT model learns physical commonsense knowledge through interaction, then uses this knowledge to ground language. |
| Approach: | They propose a model that learns physical commonsense knowledge through interaction . they factorize PIGLeT into a physical dynamics model and a separate language model . |
| Outcome: | The proposed model outperforms a 100x larger, text-to-text approach in forecasting language . it can read a sentence, simulate neurally what might happen next, and communicate that result through a literal symbolic representation, or natural language. |
Scaling Text-Rich Image Understanding via Code-Guided Synthetic Multimodal Data Generation (2025.acl-long)

Yue Yang, Ajay Patel, Matt Deitke, Tanmay Gupta, Luca Weihs, Andrew Head, Mark Yatskar, Chris Callison-Burch, Ranjay Krishna, Aniruddha Kembhavi, Christopher Clark
| Challenge: | Vision-language models struggle to understand text-rich images due to the scarcity of diverse text-only large language data. |
| Approach: | They propose a framework that leverages the coding capabilities of text-only large language models to create synthetic text-rich multimodal data. |
| Outcome: | The proposed framework can generate high-quality instruction-tuning data using Python, HTML, LaTeX and other languages. |
