Aspect-based sentiment analysis (ABSA) aims to detect the targets (which are composed by continuous words), aspects and polarities in text. Published datasets from SemEval-2015 SemEval-2016 reveal that a polarity depends on both target aspect. However, most of existing methods consider predicting either or but not both, thus they easily make wrong predictions polarities. In particular, where is implicit, i.e., it does appear given text, do work. To tackle these limitations ABSA, this paper...

This paper presents a novel pothole detection approach based on single-modal semantic segmentation. It first extracts visual features from input images using convolutional neural network. A channel attention module then reweighs the to enhance consistency of different feature maps. Subsequently, we employ an atrous spatial pyramid pooling (comprising convolutions in series, with progressive rates dilation) integrate context information. helps better distinguish between potholes and undamaged...

Abstract Few studies have addressed radiomics based differentiation of Glioblastoma (GBM) and intracranial metastatic disease (IMD). However, the effect different tumor masks, comparison single versus multiparametric MRI (mp-MRI) or select combination sequences remains undefined. We cross-compared multiple machine learning (ML) models using mp-MRI to determine optimized configurations. Our retrospective study included 60 GBM IMD patients. Forty-five combinations ML feature reduction...

Prior radiomics studies have focused on two-class brain tumor classification, which limits generalizability. The performance of in differentiating the three most common malignant tumors (glioblastoma (GBM), primary central nervous system lymphoma (PCNSL), and metastatic disease) is assessed; factors affecting model usefulness a single sequence versus multiparametric MRI (MP-MRI) remain largely unaddressed. This retrospective study included 253 patients (120 (lung brain), 40 PCNSL, 93 GBM)....

Contextual information propagation is useful for both intra- inter-shot correlations. However, traditional concatenated vector representation videos weakens power compensation among multiple modalities. In this paper, we introduce a higher-order tensor framework...

This paper presents a monocular vision based proximity estimation system using abstract features, such as corner points, blobs and edges, inputs to neural network. An experimental vehicle was built integrating the SCAMP-5 chip, micro-controller, an RC model car. The chip includes image sensor with embedded 256×256 processor SIMD array. pixel array programmed capture images run feature algorithms directly on focal plane, then digest them so that only sparse description data were read-out in...

In this study, we examine the relationship between job satisfaction and firm leverage using a sample of Chinese listed firms. We find that in "China's 100 Best Employers Award" winners during 2011–2017, is negatively associated with leverage. The effect more pronounced firms higher distress risk operating human capital intensive industries. confirm validity main findings matched series robustness checks. Overall, our results indicate can credibly demonstrate their commitment to stakeholders...

A variety of deep learning approaches have been applied to region interest (ROI) extraction, which is a fundamental task in the field remote sensing image (RSI) processing. However, unbalanced distribution positive and negative samples most RSIs greatly restricts performance these learning-based methods. In this study, data augmentation method based on variational autoencoder-multiscale generative adversarial network (VAE-MSGAN) with spatial channelwise attention (SCA) proposed balance...

China has made great efforts to fight environmental contamination along with rapid development and industrialization over the past few decades. However, effects of these nationwide measures, such as energy restructuring, on pollutant residuals in soil have not been well quantified. Polycyclic aromatic hydrocarbon (PAH) pollution is a major concern around world, PAH emissions are associated structure. Therefore, we speculated that adjustment structure may reduce content PAHs soil. To test...

Stereo vision technique has been widely used in robotic systems to acquire 3-D information. In recent years, many researchers have applied bilateral filtering stereo adaptively aggregate the matching costs. This greatly improved accuracy of estimated disparity maps. However, process whole cost volume is very time consuming and therefore resort some powerful hardware for real-time purpose. paper presents implementation fast on a state-of-the-art GPU. By highly exploiting parallel computing...
