Webexible hierarchical (multi-level) dynamic factor model. The hierarchy is produced by splitting a large panel of data into a much smaller number of blocks, each of which consists of a reasonably large number of series. We assume that each block is driven by factors that are common amongst series within the block, WebDynamic Hierarchical Mimicking. Official implementation of our DHM training mechanism as described in Dynamic Hierarchical Mimicking Towards Consistent Optimization Objectives (CVPR'20) by Duo Li and Qifeng Chen on CIFAR-100 and ILSVRC2012 benchmarks with the PyTorch framework..
