Cardiverse: Harnessing LLMs for Novel Card Game Prototyping

EMNLP 2025

The prototyping of computer games, particularly card games, requires extensive human effort in creative ideation and gameplay evaluation. Recent advances in Large Language Models (LLMs) offer opportunities to automate and streamline these processes. However, it remains challenging for LLMs to design

Learning from Synthetic Human Group Activities

CVPR 2024poster

The study of complex human interactions and group activities has become a focal point in human-centric computer vision. However progress in related tasks is often hindered by the challenges of obtaining large-scale labeled datasets from real-world scenarios. To address the limitation we introduce M3…

Harnessing Neighborhood Modeling and Asymmetry Preservation for Digraph Representation Learning

IJCAI 2023poster

Digraph Representation Learning aims to learn representations for directed homogeneous graphs (digraphs). Prior work is largely constrained or has poor generalizability across tasks. Most Graph Neural Networks exhibit poor performance on digraphs due to the neglect of modeling neighborhoods and pres…

MSI: Maximize Support-Set Information for Few-Shot Segmentation

ICCV 2023poster

FSS (Few-shot segmentation) aims to segment a target class using a small number of labeled images (support set). To extract the information relevant to target class, a dominant approach in best performing FSS methods removes background features using a support mask. We observe that this feature exci…

HM: Hybrid Masking for Few-Shot Segmentation

ECCV 2022poster

"We study few-shot semantic segmentation that aims to segment a target object from a query image when provided with a few annotated support images of the target class. Several recent methods resort to a feature masking (FM) technique to discard irrelevant feature activations which eventually facilit…

Harnessing Fourier Isovists and Geodesic Interaction for Long-Term Crowd Flow Prediction

IJCAI 2022poster

With the rise in popularity of short-term Human Trajectory Prediction (HTP), Long-Term Crowd Flow Prediction (LTCFP) has been proposed to forecast crowd movement in large and complex environments. However, the input representations, models, and datasets for LTCFP are currently limited. To this end,…

MUSE-VAE: Multi-Scale VAE for Environment-Aware Long Term Trajectory Prediction

CVPR 2022poster

Accurate long-term trajectory prediction in complex scenes, where multiple agents (e.g., pedestrians or vehicles) interact with each other and the environment while attempting to accomplish diverse and often unknown goals, is a challenging stochastic forecasting problem. In this work, we propose MUS…

SEAN 2.0: Formalizing and Generating Social Situations for Robot Navigation

RA-L 2022

We present SEAN 2.0, an open-source system designed to advance social navigation via the training and benchmarking of navigation policies in varied social contexts. A key limitation of current social navigation research is that policies are often trained and evaluated considering only a few social c

Laying the Foundations of Deep Long-Term Crowd Flow Prediction

ECCV 2020poster

Predicting the crowd behavior in complex environments is a key requirement for crowd and disaster management, architectural design, and urban planning. Given a crowd's immediate state, current approaches must be successively repeated over multiple time-steps for long-term predictions, leading to com…
