Multiscale Visual-Attribute Co-Attention for Zero-Shot Image Recognition.
IEEE Trans Neural Netw Learn Syst
September 2023
Article Synopsis
- Zero-shot image recognition seeks to classify images from classes that the system has never seen before by linking visual features with their semantic meanings.
- Existing methods typically create a single-layer embedding space for visual and semantic features, overlooking how different scales of visual data carry different meanings.
- The proposed multi-scale visual-attribute co-attention (mVACA) model incorporates a hybrid attention mechanism to enhance both the understanding of attributes and the discrimination of visuals across multiple scales, demonstrating high performance on standard benchmarks for zero-shot learning tasks.
Emergence of exchange bias field in FeS superconductor with cobalt-doping.
J Phys Condens Matter
June 2021
Among all the iron-based superconductors, the 11 series has the simplest layered structure but exhibits rich physical phenomenon. In this work, we have synthesized FeCoS single crystals with tetragonal structure and studied their structure and magnetic properties. Magnetic susceptibility measurements indicate that the cobalt doping would suppress superconductivity and even introduce weak ferromagnetism besides antiferromagnetism.

ERG plays a vital role in early seed development in . However, the mechanism that regulates seed development remains unclear.

Our results showed that SYT2 was expressed mainly in the pollen of Arabidopsis thaliana. The pollen of syt2 T-DNA and RNA interference mutant lines exhibited reduced total germination and impeded pollen tube growth.
