新的BROT方法在机器学习中实现最优传输图估计

研究人员推出了一种新颖的两步法BROT(Barycentric Regression for OT,用于OT的重心回归),用于估计最优传输(OT)图,这对于在机器学习中对齐概率分布至关重要。该方法首先计算无正则化的OT计划,然后采用通过最小二乘回归训练的深度神经网络来近似重心目标。理论证明,在地面真实OT图的Lipschitz连续性条件下,BROT可以实现minimax最优收敛速率。在合成和图像数据集上的实证评估表明,BROT在图估计、分布匹配和传输成本方面具有准确性,优于现有方法,并在单细胞扰动预测和无监督域适应等下游任务中显示出潜力。 AI

影响 引入了一种统计最优的概率分布对齐方法,有望提高各种机器学习应用的性能。
