摘要： Distributed multi-task learning (MTL) enables the joint training of multiple models by leveraging correlations between tasks, which can lead to better generalization performance. However, MTL in distributed settings faces significant communication bottlenecks, particularly in large-scale learning scenarios involving numerous tasks. This talk considers a distributed multi-task learning (MTL) system where distributed workers aim to learn different models orchestrated by a central server. To mitigate the communication bottlenecks in both the uplink and downlink, we propose a novel approach leveraging matrix multiplication. We have presented the results of achieving communication loads for both uplink and downlink under arbitrary layouts, which outperform known results and are close to the theoretical optimum. Specifically, when N = K, we achieve the optimal communication loads for both uplink and downlink as prescribed by information theory, marking a perfect attainment of the theoretical minimum.
