Abstract

Current deep neural networks (DNNs) are overparameterized and use most of their neuronal connections during inference for each task. The human brain, however, developed specialized regions for different tasks and performs inference with a small fraction of its neuronal connections. We propose an iterative pruning strategy introducing a simple importance-score metric that deactivates unimportant connections, tackling overparameterization in DNNs and modulating the firing patterns. The aim is to find the smallest number of connections that is still capable of solving a given task with comparable accuracy, i.e. a simpler subnetwork. We achieve comparable performance for LeNet architectures on MNIST, and significantly higher parameter compression than state-of-the-art algorithms for VGG and ResNet architectures on CIFAR-10/100 and Tiny-ImageNet. Our approach also performs well for the two different optimizers considered—Adam and SGD. The algorithm is not designed to minimize FLOPs when considering current hardware and software implementations, although it performs reasonably when compared to the state of the art.

神经网络救济:基于神经活动的剪枝算法
摘要 当前的深度神经网络(DNN)参数过高,在推理每个任务时都会使用大部分神经元连接。然而,人类大脑为不同的任务开发了专门的区域,并使用其神经元连接的一小部分执行推理。我们提出了一种迭代剪枝策略,引入了一个简单的重要性分数指标,停用不重要的连接,解决 DNN 中的过度参数化问题,并调节发射模式。这样做的目的是找到最小数量的连接,这些连接仍能以相当的精度解决给定任务,即一个更简单的子网络。我们在 MNIST 上实现了与 LeNet 架构相当的性能,在 CIFAR-10/100 和 Tiny-ImageNet 上实现了比 VGG 和 ResNet 架构先进算法更高的参数压缩率。我们的方法在两种不同的优化器--Adam 和 SGD 中也表现出色。考虑到当前的硬件和软件实现,该算法并不是为了最小化 FLOPs 而设计的,不过与最先进的算法相比,它的表现还算合理。
