arXiv:2606.02221v1 Announce Type: cross Abstract: Multi-task learning (MTL) aims to construct a joint model for multiple tasks by sharing a common representation across domains. To achieve this goal, existing optimization-centric methods either balance task gradients or modify the shared architecture. However, as these approaches remain agnostic to the content of the shared representation, they fail to disentangle task-relevant structure from spurious context, leading to negative transfer and poor generalization. To overcome this limitation, we propose Causal Orthogonal Representations for Mul
The paper addresses a core limitation in multi-task learning (MTL), a foundational AI technique, suggesting a new path forward in a field rapidly iterating on efficiency and effectiveness.
Improved multi-task learning through better representation disentanglement could lead to more robust, efficient, and generalizable AI models, impacting a wide range of applications from computer vision to agentic systems.
Current gradient balancing and architectural approaches in MTL may be superseded or significantly augmented by methods focusing on causal orthogonal representations, leading to less negative transfer and improved generalization.
