Therefore, there are only three parameters left for the BO agent to optimize. 1 and high-5 accuracy achieved by different methods when pruning 50% for ResNet56. The rollback scheme additional improves the accuracy by 0.9%. Notice that in (He et al. Our proposed layer clustering technique improves BO’s performance with 1.4% larger in high-1 accuracy. 2018), the writer claimed that AMC can obtain a 90.2% top1 accuracy in four hundred epochs. The desk additionally reveals that the BO agent outperforms RL in effectivity by a large margin. For comparability, the most effective top1 accuracy of our proposed rollback method is as much as 93.14 %, which is significantly higher than the result in (He et al.

Our experiments present that our rollback algorithm will further enhance the pruning accuracy, resulting in extra promising pruning insurance policies which won’t be found within the naive BO and the clustering-based mostly BO. The accuracy is estimated primarily based on a random subset of the training set, whose sizes are 5000 and 3000 for Cifar10 ILSVRC2012, respectively. To make a good comparison, we undertake the identical channel pruning scheme with the RL counterpart. In our experiments, we use GpyOpt (SheffieldML 2016) as the essential BO agent and implement the proposed strategies base on it. RL agent in (He et al. 2018) can also be carried out as a baseline. We conduct our experiments on several representative CNN mannequin architectures, together with ResNet56 (He et al.
Moreover, our technique achieves lower variance and shorter time than the RL-primarily based counterpart. There is a growing pattern to use CNNs in different scenarios (mouse click the next web page) corresponding to object detection, speech recognition, and so forth. However, the excessive performance of CNNs is at the expense of their massive model dimension and high computing complexity, which have prevented it from having a broader usage. Convolutional neural networks (CNN (www.pipihosa.com/2018/11/26/4224367-general-electric-bankruptcy-talk/)) have gotten fashionable as a consequence of their excessive performance and universality.
RL agent is far higher than our proposed layer clustering and the rollback algorithm. After its convergence, the rollback scheme turns the design house again right into a excessive-dimensional house and can additional improve the accuracy of the pruned network. Thus, our method is also way more efficient from the angle of wall clock time. In Fig. 3(a), we show the effectiveness of the proposed methods intimately. Observe that all strategies take around 2300 seconds to finish 200 epochs, which signifies the time spent for each trial in BO and RL is close and the time overhead of rollback is ignorable. Clearly, the layer clustering method can significantly enhance the convergence of the BO agent.
