A key component of deep convolutional neural network training is feature normalization, which aims to increase stability, reduce internal covariate shifts, and boost network performance. The development of several normalization approaches has resulted in the development of batch, group, layer, and instance normalization. Batch normalization is one of these that is frequently used, particularly in computer vision applications.
Convolution-BatchNorm (ConvBN) blocks are essential to many computer vision jobs and other fields. Train, Eval, and Deploy are the three different modes in which these blocks can function. The ConvBN block consists of a convolutional layer followed by a batch normalization layer. When mini-batch statistics are unavailable, running statistics are tracked for testing individual cases.
In train mode, mini-batch statistics are produced for feature normalization during training. Eval mode provides validation and model development efficiency by directly using running data for feature normalization. Deploy mode removes batch normalization for faster inference and streamlines computation by combining convolution, normalization, and affine transformations into a single convolutional operator. It is utilized during deployment when additional training is not required.
In a recent study, a team of researchers has explored the efficiency and stability trade-off that ConvBN blocks inevitably present. Although deploy mode is known for its effectiveness, training instability is a problem. The efficiency seen in the deployment mode is absent from the evaluation mode, which is preferred in transfer learning settings.
The team has theoretically explored the causes of the reduced training stability seen in the Deploy mode. To address them, they have presented a new mode called the Tune mode. Tune mode attempts to close the gap between deploy and eval modes. For transfer learning, the suggested Tune mode has been positioned as a reliable substitute for the Eval mode, and its computing efficiency is nearly identical to that of the Deploy mode.
The team has shared that while approaching the computational efficiency of the Deploy mode, the tune mode maintains functional equivalency with the eval mode in both forward and backward propagation. The team has shown a considerable decrease in memory footprint and wall-clock training time without sacrificing performance through thorough testing across a range of workloads, model topologies, and datasets.
In-depth tests have been carried out on a range of tasks, such as object detection and classification, using various datasets and model architectures in order to validate their methodology. The outcomes have demonstrated that the suggested Tune mode greatly minimizes GPU memory footprint and training time while preserving the original performance.
In conclusion, the suggested Tune mode achieves computational efficiency similar to the Deploy mode and stability similar to the Eval mode. Empirical data from trials conducted in a variety of circumstances highlights how well Tune mode works to improve the effectiveness of transfer learning using convolutional networks.
