Large-batch Optimization for Dense Visual Predictions: Training Faster R-CNN in 4.2 Minutes
Training a large-scale deep neural network in a large-scale dataset is challenging and time-consuming. The recent breakthrough of large-batch optimization is a promising way to tackle this challenge. However, although the current advanced algorithms such as LARS and LAMB succeed in classification models, the complicated pipelines of dense visual predictions such as object detection and segmentation still suffer from the heavy performance drop in the large-batch training regime. To address this challenge, we propose a simple yet effective algorithm, named Adaptive Gradient Variance Modulator (AGVM), which can train dense visual predictors with very large batch size, enabling several benefits more appealing than prior arts. Firstly, AGVM can align the gradient variances between different modules in the dense visual predictors, such as backbone, feature pyramid network (FPN), detection, and segmentation heads.

Training Faster R-CNN Using TensorFlow's Object Detection API with a Custom Dataset
Recently, object detection has continued to evolve from its current state, and due to its technology, it can be found across almost every technological platform. Whether it is through image classification, recognition, or localization, these are all based on object detection. Convolutional neural networks (CNNs) can bring together many object recognition and classification techniques together by incorporating deep learning and computer vision methods. In computer vision, convolutional neural networks, as the name suggests, apply a convolution layer in each pixel image in a dataset. Due to computer vision and deep learning fundamentals in its primary structure, CNNs obtain a different output layer step-by-step by moving the filter we specify onto an image.
