Decoupled Training: Return of Frustratingly Easy Multi-Domain Learning

AAAI 2024technical

Multi-domain learning (MDL) aims to train a model with minimal average risk across multiple overlapping but non-identical domains. To tackle the challenges of dataset bias and domain domination, numerous MDL approaches have been proposed from the perspectives of seeking commonalities by aligning dis…

ForkMerge: Mitigating Negative Transfer in Auxiliary-Task Learning

NeurIPS 2023poster

Auxiliary-Task Learning (ATL) aims to improve the performance of the target task by leveraging the knowledge obtained from related tasks. Occasionally, learning multiple tasks simultaneously results in lower accuracy than learning only the target task, which is known as negative transfer. This probl…

Cross-Task Knowledge Distillation in Multi-Task Recommendation

AAAI 2022technical

Multi-task learning (MTL) has been widely used in recommender systems, wherein predicting each type of user feedback on items (e.g, click, purchase) are treated as individual tasks and jointly trained with a unified model. Our key observation is that the prediction results of each task may contain t…

Decision Making for Autonomous Driving via Augmented Adversarial Inverse Reinforcement Learning

ICRA 2021poster

Making decisions in complex driving environments is a challenging task for autonomous agents. Imitation learning methods have great potentials for achieving such a goal. Adversarial Inverse Reinforcement Learning (AIRL) is one of the state-of-art imitation learning methods that can learn both a beha…
