面部检测是计算机愿景领域的长期挑战,最终目标是准确地将人类面临着不受约束的环境。由于与姿势,图像分辨率,照明,闭塞和观点相关的混淆因素,使这些系统具有重要的技术障碍。据说,随着最近的机器学习的发展,面部检测系统实现了非凡的准确性,主要是基于数据驱动的深度学习模型[70]。虽然鼓励,限制了部署系统的面部检测性能和社会责任的关键方面是人类外观的固有多样性。每个人类的外表都反映了一个人的东西,包括他们的遗产,身份,经验和自我表达的可见表现。但是,有关面部检测系统如何在面对不同的面部尺寸和形状,肤色,身体修改和身体装饰方面进行良好的表现问题。为了实现这一目标,我们收集了独特的人类外观数据集,这是一种图像集,表示具有低频率的外观,并且往往是面部数据集的缺点。然后,我们评估了当前最先进的脸部检测模型,其能够检测这些图像中的面部。评估结果表明,面部检测算法对这些不同的外观没有概括。评估和表征当前的面部检测模型的状态将加速研究和开发,以创造更公平和更准确的面部检测系统。

This work addresses an alternative approach for query expansion (QE) using a generative adversarial network (GAN) to enhance the effectiveness of information search in e-commerce. We propose a modified QE conditional GAN (mQE-CGAN) framework, which resolves keywords by expanding the query with a synthetically generated query that proposes semantic information from text input. We train a sequence-to-sequence transformer model as the generator to produce keywords and use a recurrent neural network model as the discriminator to classify an adversarial output with the generator. With the modified CGAN framework, various forms of semantic insights gathered from the query document corpus are introduced to the generation process. We leverage these insights as conditions for the generator model and discuss their effectiveness for the query expansion task. Our experiments demonstrate that the utilization of condition structures within the mQE-CGAN framework can increase the semantic similarity between generated sequences and reference documents up to nearly 10% compared to baseline models
