Hi, My name is Dong Won. My advisors and friends usually call me “Don" :) I’m a PhD Student at MIT working on the foundations of multimodal social agents, where I focus on developing machine learning methods and evaluation for social intelligence. I am extremely grateful to be co-advised by Professor Cynthia Breazeal in the Personal Robots Group at the Media Lab and Professor Louis-Philippe Morency at the Language Technologies Institute at CMU. Prior to MIT, I graduated with a Master's in Machine Learning and Bachelor's in Statistics and Machine Learning from Carnegie Mellon University.

08/2023: I'll be TA'ing and mentoring students for MIT MAS.630 Affective Computing and Ethics taught by Rosalind Picard at the MIT Media Lab, where I'll be giving lectures on advancements in Machine Learning for Affective Computing and Social Intelligence in LLMs. We encourage interested MIT/Harvard students to sign up for our class to learn about the future of Socio-Emotional AI! 07/2023: Our paper on Lecture Presentations Multimodal Dataset: Towards Understanding Multimodality in Educational Videos is accepted at ICCV 2023! 07/2023: Our paper on HIINT: Historical, Intra-and Inter-personal Dynamics Modeling with Cross-person Memory Transformer is accepted at ICMI 2023! 04/2023: Our paper on Multipar-T: Multiparty-Transformer for Capturing Contingent Behaviors in Group Conversations is accepted at IJCAI 2023! 03/2023: Our proposal for the 1st Workshop on Social and Affective Intelligence (SAI) has been accepted at ACII 2023! Please consider submitting your work! 03/2022: Our paper on Low-resource Adaptation for Personalized Co-Speech Gesture Generation is accepted at CVPR 2022. 07/2021: Our paper on Crossmodal clustered contrastive learning: Grounding of spoken language to gestures is accepted to GENEA Workshop @ ICMI 2021. 05/2021: We are organizing the First Workshop on Crossmodal Social Animation at ICCV 2021. 09/2020: Our paper on No Gestures Left Behind: Learning Relationships between Spoken Language and Freeform Gestures is accepted at Findings at EMNLP 2020. 07/2020: Our paper on Style Transfer for Co-Speech Gesture Animation is accepted at ECCV 2020 |

Dong Won Lee, Chaitanya Ahuja, Paul Pu Liang, Sanika Natu, Louis-Philippe Morency ICCV, 2023 paper / code We introduce the Multimodal Lecture Presentations dataset and PolyViLT a multimodal transformer trained with a multi-instance learning loss. We propose a large-scale benchmark testing the capabilities of machine learning models in multimodal understanding of educational content. |

Yubin Kim, Dong Won Lee, Paul Pu Liang, Sharifa Algohwinem, Cynthia Breazeal, Hae Won Park ICMI, 2023 paper We model the Historical, Intra-and Inter-personal (HIINT) Dynamics in conversation by incorporating memory modules in the Cross-person Memory Transformer to address temporal coherence and better represent the context of conversational behaviors. |

Chaitanya Ahuja, Dong Won Lee, Louis-Philippe Morency CVPR, 2022 paper / We propose a new approach in crossmodal generative modeling in low-resource settings in the hopes to to create a personalized gesture generation model (e.g. as part of a personalized avatar) with limited data from a new speaker. |

I have been blessed to meet amazing mentors who have guided me to become a better researcher (and more importantly, a good person). I believe that I can only repay what they've done for me by assisting others in their journey in any way I can. Please don't hesitate to reach out! Mentors and Advisors: (in Alphabetical Order)
