An Exterior Method for Nonnegative Matrix Factorization
Qiujing Lu, Tonmoy Monsoor, Ehsan Ebrahimzadeh +2
Nonnegative matrix factorization (NMF) seeks a low-rank approximation with nonnegative factors and is commonly solved using interior methods that enforce feasibili…
Action-conditioned On-demand Motion Generation
Qiujing Lu, Yipeng Zhang, Mingjian Lu +1
We propose a novel framework, On-Demand MOtion Generation (ODMO), for generating realistic and diverse long-term 3D human motion sequences conditioned only on action types with an…
KEMP: Keyframe-Based Hierarchical End-to-End Deep Model for Long-Term Trajectory Prediction
Qiujing Lu, Weiqiao Han, Jeffrey Ling +4
Predicting future trajectories of road agents is a critical task for autonomous driving. Recent goal-based trajectory prediction methods, such as DenseTNT and PECNet, have shown go…
Diverse Imitation Learning via Self-Organizing Generative Models
Arash Vahabpour, Tianyi Wang, Qiujing Lu +2
Imitation learning is the task of replicating expert policy from demonstrations, without access to a reward function. This task becomes particularly challenging when the expert exh…
