在Residual and Plain Convolutional Neural Networks for 3D Brain MRI Classification中,批量归一化在训练过程中起到了非常重要的作用,但是批量归一化的过程也会对网络的收敛速度和精度产生影响。因此,我们可以尝试修改批量迭代过程,以提高网络的性能。
一种可能的修改方法是使用动态批量大小,即在训练过程中逐渐增加批量大小。这种方法可以使网络逐渐适应更大的批量大小,从而提高网络的性能。具体实现时,可以在每个epoch开始时,将批量大小逐渐增加一定比例,直到达到最大值。
另外,我们还可以使用自适应批量大小,即根据训练数据的分布情况来动态调整批量大小。具体实现时,可以在每个epoch开始时,对训练数据进行分析,然后根据数据分布情况来调整批量大小。例如,如果某些类别的样本数量比较少,可以适当增加批量大小,以增加这些类别的样本在训练中的影响力。
总之,修改批量迭代过程是一种有效的提高网络性能的方法,但是需要根据具体问题进行调整和实验。

R3D residual network
R3D (Residual 3D) network is a type of 3D convolutional neural network (CNN) architecture that is designed for video classification tasks. It builds upon the idea of residual connections in the ResNet architecture to improve the training and performance of 3D CNNs.
In the R3D architecture, residual connections are added between convolutional layers, which allows the network to learn the residual information between feature maps and avoid the vanishing gradient problem. Additionally, the R3D network uses 3D convolutional filters to capture spatiotemporal features in videos, allowing it to better model the motion information in video frames.
R3D networks have been used successfully in various video classification tasks, such as action recognition, gesture recognition, and video captioning.
