新方法为深度神经网络稀疏性提供自适应控制

研究人员开发了一种自适应正则化方法,以更好地控制深度神经网络中的稀疏性,解决了传统 $\ell_1$ 惩罚会间接影响稀疏率的挑战。该新方案根据模型当前稀疏率与目标稀疏率之间的差异动态调整正则化参数。在说话人验证任务上的实验表明,与密集模型相比,自适应方法能够可靠地实现 75% 到 99% 之间的稀疏性目标,在早期训练中收敛更快,并保持了更好的分布外鲁棒性。 AI

影响 通过对网络稀疏性进行精确控制,能够实现更高效的深度学习模型,有望降低计算成本并提高性能。

    Bregman优化器中用于稀疏性控制的自适应正则化

    Sparse training reduces the memory and computational costs of deep neural networks. However, sparse optimization methods, e.g., those adding an $\ell_1$ penalty, often control sparsity only indirectly through a regularization parameter $λ$, whose mapping to the final sparsity rat…
