论文摘要

流行人群计数数据集中的数据分布通常是沉重的尾巴和不连续的。这偏斜会影响深人群计数方法的管道中的所有阶段。具体而言,这些方法表现出令人难以置信的大型标准偏差WRT统计措施(MSE,MAE)。为了整体解决此类问题,我们做出了两个基本贡献。首先,我们修改培训管道以适应数据集偏斜的知识。为了启用原则性和平衡的Minibatch采样,我们提出了一种新颖的平滑贝叶斯式binning方法。更具体地说,我们提出了一种新颖的成本功能,可以很容易地将其纳入现有的人群中,以鼓励bin Aware-Aware优化。作为第二个贡献,我们引入了更具包容性的其他绩效指标,并阐明了深网的各种比较性能方面。我们还表明,我们的基于binning的修改保留了新提出的绩效指标的优势。总体而言,我们的贡献使实际上有用且面向细节的性能表征人群计数方法。

The data distribution in popular crowd counting datasets is typically heavy tailed and discontinuous. This skew affects all stages within the pipelines of deep crowd counting approaches. Specifically, the approaches exhibit unacceptably large standard deviation wrt statistical measures (MSE, MAE). To address such concerns in a holistic manner, we make two fundamental contributions. Firstly, we modify the training pipeline to accommodate the knowledge of dataset skew. To enable principled and balanced minibatch sampling, we propose a novel smoothed Bayesian binning approach. More specifically, we propose a novel cost function which can be readily incorporated into existing crowd counting deep networks to encourage bin-aware optimization. As the second contribution, we introduce additional performance measures which are more inclusive and throw light on various comparative performance aspects of the deep networks. We also show that our binning-based modifications retain their superiority wrt the newly proposed performance measures. Overall, our contributions enable a practically useful and detail-oriented characterization of performance for crowd counting approaches.
