RIANet: Road Graph and Image Attention Network for Urban Autonomous Driving

IROS 2022poster

In this paper, we present a novel autonomous driving framework, called a road graph and image attention network (RIANet), which computes the attention scores of objects in the image using the road graph feature. The process of the proposed method is as follows: First, the feature encoder module enco…

Deep Predictive Autonomous Driving Using Multi-Agent Joint Trajectory Prediction and Traffic Rules

IROS 2019poster

Autonomous driving is a challenging problem because the autonomous vehicle must understand complex and dynamic environment. This understanding consists of predicting future behavior of nearby vehicles and recognizing predefined rules. It is observed that not all rules have equivalent values, and the…

Text2Action: Generative Adversarial Synthesis from Language to Action

ICRA 2018poster

In this paper, we propose a generative model which learns the relationship between language and human action in order to generate a human action sequence given a sentence describing human behavior. The proposed generative model is a generative adversarial network (GAN), which is based on the sequenc…
