In recent years, question answering (QA) and reading comprehension (RC) has attracted much attention, most research on QA focused multi-hop task which requires connecting multiple pieces of evidence scattered in a long context to answer the question. The key is semantic feature interaction between documents questions, widely processed by Bi-directional Attention Flow (Bi-DAF), but Bi-DAF genera...

In this paper, we focus on fine-grained recognition of vehicles mainly in traffic surveillance applications. We propose an approach orthogonal to recent advancement in fine-grained recognition (automatic part discovery, bilinear pooling). Also, in contrast to other methods focused on fine-grained recognition of vehicles, we do not limit ourselves to frontal/rear viewpoint but allow the vehicles...

In fine-grained action (object manipulation) recognition, it is important to encode object semantic (contextual) information, i.e., which object is being manipulated and how it is being operated. However, previous methods for action recognition often represent the semantic information in a global and coarse way and therefore cannot cope with fine-grained actions. In this work, we propose a repr...

Structural transformations caused by coarse-grained powdering and fine-grained mechanochemical milling in a dry mode were probed in high-temperature modification of tetra-arsenic tetra-sulfide known as β-As4S4. In respect to X-ray diffraction analysis, the characteristic sizes of β-As4S4 crystallites in these coarse- and fine-grained powdered pellets were 90 and 40 nm, respectively. Positron an...
