As an essential approach in many Internet of Things (IoT) applications, multiview learning synthesizes multiple features to achieve more comprehensive descriptions data items. Most the previous studies on have been dedicated increasing prediction accuracy, while ignoring reliability decision. This would limit their deployment high-risk IoT and industrial applications such as automated vehicle. Although a trusted classification model has proposed recently, it cannot well deal with highly...

Product reviews are valuable for upcoming buyers in helping them make decisions. To this end, different opinion mining techniques have been proposed, where judging a review sentence's orientation (e.g., positive or negative) is one of their key challenges. Recently, deep learning has emerged as an effective means solving sentiment classification problems. A neural network intrinsically learns useful representation automatically without human efforts. However, the success highly relies on...

Multi-view clustering aims to leverage information from multiple views improve clustering. Most previous works assumed that each view has complete data. However, in real-world datasets, it is often the case a may contain some missing data, resulting incomplete multi-view problem. Previous methods for this problem have at least one of following drawbacks: (1) employing shallow models, which cannot well handle dependence and discrepancy among different views; (2) ignoring hidden data; (3)...

With the application requirement, technique for change detection based on heterogeneous remote sensing images is paid more attention. However, detecting changes between two challenging as they cannot be compared in low-dimensional space. In this paper, we construct an approximately symmetric deep neural network with sides containing same number of coupled layers to transform into feature The are connected and transformed space, which their features discriminative difference image can...

Graph Convolutional Network (GCN) has achieved extraordinary success in learning effective task-specific representations of nodes graphs. However, regarding Heterogeneous Information (HIN), existing HIN-oriented GCN methods still suffer from two deficiencies: (1) they cannot flexibly explore all possible meta-paths and extract the most useful ones for a target object, which hinders both effectiveness interpretability; (2) often need to generate intermediate meta-path based dense graphs,...

Bidding optimization is one of the most critical problems in online advertising. Sponsored search (SS) auction, due to randomness user query behavior and platform nature, usually adopts keyword-level bidding strategies. In contrast, display advertising (DA), as a relatively simpler scenario for has taken advantage real-time (RTB) boost performance advertisers. this paper, we consider RTB problem sponsored named SS-RTB. SS-RTB much more complex dynamic environment, stochastic policies based...

Multiview representation learning (MVRL) leverages information from multiple views to obtain a common summarizing the consistency and complementarity in multiview data. Most previous matrix factorization-based MVRL methods are shallow models that neglect complex hierarchical information. The recently proposed deep factorization cannot explicitly capture We present concept (DMCL) method, which hierarchically factorizes data, tries model consistent complementary semantic structures at highest...

Nowadays, a lot of people possess accounts on multiple online social networks, e.g., Facebook and Twitter. These networks are overlapped, but the correspondences between their users not explicitly given. Mapping common across these will be beneficial for applications such as cross-network recommendation. In recent years, mapping algorithms have been proposed which exploited and/or profile relations from different networks. However, there is still lack unified framework can well exploit...

Graph Convolutional Networks (GCNs) suffer from performance degradation when models go deeper. However, earlier works only attributed the degeneration to over-smoothing. In this paper, we conduct theoretical and experimental analysis explore fundamental causes of in deep GCNs: over-smoothing gradient vanishing have a mutually reinforcing effect that deteriorate more quickly GCNs. On other hand, existing anti-over-smoothing methods all perform full convolutions up model depth. They could not...

Multi-layer networks provide an effective and efficient tool to model characterize complex systems with multiple types of interactions, which differ greatly from the traditional single-layer networks. Graph clustering in multi-layer is highly non-trivial since it difficult balance connectivity clusters connection various layers. The current algorithms for layer-specific are criticized low accuracy sensitivity perturbation To overcome these issues, a novel algorithm module based on...

Background: Management of patients with non-obstructive coronary artery disease (CAD) identified by CT angiography (CCTA) remains challenging due to the lacks clear guidelines. Traditional anatomical evaluation techniques might not reliably pinpoint those at an increased risk for cardiovascular events, creating a critical gap in patient care. Although derived fractional flow reserve (CT-FFR) provides non-invasive functional assessment and is increasingly recognized as crucial tool deciding...

Recently, several spatial-temporal memory-based methods have verified that storing intermediate frames with masks as memory helps segment target objects in videos. However, they mainly focus on better matching between the current frame and without paying attention to quality of memory. Consequently, poor segmentation may be memorized, leading error accumulation problems. Besides, linear increase growth numbers limits ability models handle long To this end, we propose a Quality-aware Dynamic...
