Semantic guided level-category hybrid prediction network for hierarchical image classification 语义引导的分层图像分类层次-类别混合预测网络

Hierarchical classification (HC) assigns each object with multiple labels organized into a hierarchical structure. The existing deep learning-based HC methods usually predict an instance starting from the root node until a leaf node is reached. However, in the real world, images impaired by noise, occlusion, blur, or low resolution may not provide sufficient information for the classification at subordinate levels. To address this issue, we propose a novel Semantic Guided level-category Hybrid Prediction Network (SGHPN) that can jointly perform the level and category prediction in an end-to-end manner. SGHPN comprises two modules: a visual transformer that extracts feature vectors from the input images, and a semantic guided cross-attention module that uses categories word embeddings as queries to guide learning category-specific representations. In order to evaluate the proposed method, we construct two new datasets in which images are at a broad range of quality and thus are labeled to different levels (depths) in the hierarchy according to their individual quality. Experimental results demonstrate the effectiveness of our proposed HC method.
层次分类(HC)为每个对象分配多个标签,这些标签组织成层次结构。现有的基于深度学习的HC方法通常从根节点开始预测实例,直到到达叶节点。然而,在现实世界中,受噪声、遮挡、模糊或低分辨率影响的图像可能无法为下级分类提供足够的信息。为了解决这一问题,我们提出了一种新的语义引导水平-类别混合预测网络(SGHPN),该网络可以以端到端方式联合执行水平和类别预测。SGHPN包括两个模块:一个是从输入图像中提取特征向量的视觉转换器,以及一个语义引导的交叉注意模块,该模块使用类别词嵌入作为查询来指导学习特定类别的表示。为了评估所提出的方法,我们构建了两个新的数据集,其中图像的质量范围很广,因此根据它们的个人质量在层次结构中被标记为不同的层次(深度)。实验结果证明了该方法的有效性。

Aquila optimizer (AO) is an efficient meta-heuristic optimization method, which mimics the hunting style of Aquila in nature. However, the AO algorithm may suffer from immature convergence during the exploitation stage. In this paper, two strategies are elegantly employed into conventional AO, such as random opposition-based learning and nonlinear flexible jumping factor, which can efficiently enhance the performance of conventional AO. Experiments on [Formula: see text] benchmark functions and image segmentation demonstrate the effectiveness of the proposed algorithm. Comparison with several state-of-the-art meta-heuristic optimization techniques indicates the efficacy of the developed method.

. The null space property (NSP), which relies merely on the null space of the sensing matrix column space, has drawn numerous interests in sparse signal recovery. This article studies NSP of the weighted ℓ r − ℓ 1 minimization. Several versions of NSP of the weighted ℓ r − ℓ 1 minimization including the weighted ℓ r − ℓ 1 NSP, the weighted ℓ r − ℓ 1 stable NSP, the weighted ℓ r − ℓ 1 robust NSP, and the ℓ q weighted ℓ r − ℓ 1 NSP for 1 ≤ q ≤ 2, are proposed, as well as the associating considerable results are derived. Under these NSP, sufficient conditions for the recovery of (sparse) signals with the weighted ℓ r − ℓ 1 minimization are established. Furthermore, we show that to some extent, the weighted ℓ r − ℓ 1 stable NSP is weaker than the restricted isometric property (RIP). And the RIP condition we obtained is better than that of Zhou Z. (2022).
