    PVLR: Prompt-driven Visual-Linguistic Representation Learning for Multi-Label Image Recognition

    Multi-label image recognition is a fundamental task in computer vision. Recently, vision-language models have made notable advancements in this area. However, previous methods often failed to effectively leverage the rich knowledge within language models and instead incorporated label semantics into visual features in a unidirectional manner. In this paper, we propose a Prompt-driven Visual-Linguistic Representation Learning (PVLR) framework to better leverage the capabilities of the linguistic modality. In PVLR, we first introduce a dual-prompting strategy comprising Knowledge-Aware Prompting (KAP) and Context-Aware Prompting (CAP). KAP utilizes fixed prompts to capture the intrinsic semantic knowledge and relationships across all labels, while CAP employs learnable prompts to capture context-aware label semantics and relationships. Later, we propose an Interaction and Fusion Module (IFM) to interact and fuse the representations obtained from KAP and CAP. In contrast to the unidirectional fusion in previous works, we introduce a Dual-Modal Attention (DMA) that enables bidirectional interaction between textual and visual features, yielding context-aware label representations and semantic-related visual representations, which are subsequently used to calculate similarities and generate final predictions for all labels. Extensive experiments on three popular datasets including MS-COCO, Pascal VOC 2007, and NUS-WIDE demonstrate the superiority of PVLR.Comment: 15 pages, 8 figure

    精神病专科医院生存状况不容乐观。以“大专科、大综合”模式发展精神病专科医院能提高医院管理水平,改善财政状况,改变设备不全、人才缺乏等现状,提高危急重症病人救治能力及科研教学水平,促进医院发展。The contemporary performance of mental hospitals goes below our best expectation. Developing mental hospital with the mode of “combined psychiatry and comprehensive medical” would increase the ability of management, improve financial state, change the present circumstance of incomplete equipment and personnel lack, enhance endangered patients’ treatment as well as scientific research and teaching and, finally, promote the development of hospital

    In the title compound, [Ni(C6H6NO3S)2(C3H7NO)2(H2O)2]·2H2O, the NiII ion (site symmetry ) is coordinated by two –NH2 groups from two 4-amino­benzene­sulfonate anions, two O atoms from two dimethyl­formamide mol­ecules and two water mol­ecules, forming a slightly distorted trans-NiN2O4 octa­hedral geometry. In the crystal structure, inter­molecular O—H⋯O, O—H⋯(O,O) and N—H⋯O hydrogen bonds link the components into a three-dimensional network. The O atoms of the sulfonate group are disordered over two sets of sites in a 0.833 (4):0.167 (4) ratio and the O atom of the uncoordinated water mol­ecule is disordered over two sites in a 0.637 (18):0.363 (18) ratio
