This article is mainly to study the realization of travel recommendations for different users through deep learning under global information management. The personalized travel route recommendation is realized by establishing personalized travel dynamic interest (PTDR) algorithm and distributed lock manager (DLM) model. It is hoped that this model can provide more complete data information of tourist destinations on the basis of the past, and can also meet the needs of users. The innovation of this article is to compare and analyze with a large number of baseline algorithms, highlighting the superiority of this model in personalized travel recommendation. In addition, the model incorporates the topic factor features, geographic factor features, and user preference features to make the data more in line with user needs and improve the efficiency and applicability of the model. It is hoped that the plan proposed in this article can help users make choices of tourist destinations more conveniently.

Proper features matter for salient object detection. Existing methods mainly focus on designing a sophisticated structure to incorporate multi-level features and filter out cluttered features. We present the dual-branch feature fusion network (DBFFNet), a simple effective framework mainly composed of three modules: global information perception module, local information concatenation module and refinement fusion module. The local information of a salient object is extracted from the local information concatenation module. The global information perception module exploits the U-Net structure to transmit the global information layer by layer. By employing the refinement fusion module, our approach is able to refine features from two branches and detect salient objects with final details without any post-processing. Experiments on standard benchmarks demonstrate that our method outperforms almost all of the state-of-the-art methods in terms of accuracy, and achieves the best performance in terms of speed under fair settings. Moreover, we design a wide-field optical system and combine with DBFFNet to achieve salient object detection with large field of view.

Graph Neural Networks (GNNs) rely on the graph structure to define an aggregation strategy where each node updates its representation by combining information from its neighbours. A known limitation of GNNs is that, as the number of layers increases, information gets smoothed and squashed and node embeddings become indistinguishable, negatively affecting performance. Therefore, practical GNN models employ few layers and only leverage the graph structure in terms of limited, small neighbourhoods around each node. Inevitably, practical GNNs do not capture information depending on the global structure of the graph. While there have been several works studying the limitations and expressivity of GNNs, the question of whether practical applications on graph structured data require global structural knowledge or not remains unanswered. In this work, we empirically address this question by giving access to global information to several GNN models, and observing the impact it has on downstream performance. Our results show that global information can in fact provide significant benefits for common graph-related tasks. We further identify a novel regularization strategy that leads to an average accuracy improvement of more than 5% on all considered tasks.

Abstract This article rethinks the history of Chinese script reforms and proposes a new genealogy for the Chinese Latin Alphabet (CLA), invented in 1931 by Chinese and Russian revolutionaries in the Soviet Union. Situating script reforms within a global information age that emerged out of the nineteenth-century communications revolution, the article historicizes the CLA within a technologically and ideologically contrived Sino-Soviet space. In particular, it shows the intimate links between the CLA and the Unified New Turkic Alphabet (UNTA), which grew out of a latinization movement based in Baku, Azerbaijan. The primary purpose of the UNTA was to latinize the Arabic script of the Turkic people living in Soviet Central Asia, but it was immediately exported to the non-Turkic world as well in an effort to latinize languages across Eurasia and ignite revolutionary internationalism. This article investigates the forgotten figures involved in carrying the Latin alphabet from Baku to Shanghai and offers a new framework to scrutinize the history of language, scripts, and knowledge production across Eurasia.

This study proposed a medicine auxiliary diagnosis model based on neural network. The model combines a bidirectional long short-term memory(Bi-LSTM)network and bidirectional encoder representations from transformers (BERT), which can well complete the extraction of local features of Chinese medicine texts. BERT can learn the global information of the text, so use BERT to get the global representation of medical text and then use Bi-LSTM to extract local features. We conducted a large number of comparative experiments on datasets. The results show that the proposed model has significant advantages over the state-of-the-art baseline model. The accuracy of the proposed model is 0.75.

Bokeh effect is growing to be an important feature in photography, essentially to choose an object of interest to be in focus with the rest of the background being blurred. While naturally rendering this effect requires a DSLR with large diameter of aperture, with the current advancements in Deep Learning, this effect can also be produced in mobile cameras. Most of the existing methods use Convolutional Neural Networks while some relying on the depth map to render this effect. In this paper, we propose an end-to-end Vision Transformer model for Bokeh rendering of images from monocular camera. This architecture uses vision transformers as backbone, thus learning from the entire image rather than just the parts from the filters in a CNN. This property of retaining global information coupled with initial training of the model for image restoration before training to render the blur effect for the background, allows our method to produce clearer images and outperform the current state-of-the-art models on the EBB! Data set. The code to our proposed method can be found at: https://github.com/Soester10/ Bokeh-Rendering-with-Vision-Transformers.

Clinical practice guidelines are procedures, ideas, integrating records, multiple interventions, and decisions that are systematically developed to support professional and patient decisions about healthcare appropriate to specific clinical circumstances. The sudden pandemic that occurred in December 2019 that devastated the world forced reflection and globalized intervention. It was necessary, in a short time, to elaborate and disseminate a set of key rules in order to be able to control the coronavirus pandemic, global information, the protection and safety of people, and the treatment of patients and multiple and complex issues brought up in a communication crisis. In this chapter the author evaluates some of the moments of this global communication led by the World Health Organization and supported by the Centers for Disease Control and Prevention and other entities.

In this paper, we propose a new method for detecting abnormal human behavior based on skeleton features using self-attention augment graph convolution. The skeleton data have been proved to be robust to the complex background, illumination changes, and dynamic camera scenes and are naturally constructed as a graph in non-Euclidean space. Particularly, the establishment of spatial temporal graph convolutional networks (ST-GCN) can effectively learn the spatio-temporal relationships of Non-Euclidean Structure Data. However, it only operates on local neighborhood nodes and thereby lacks global information. We propose a novel spatial temporal self-attention augmented graph convolutional networks (SAA-Graph) by combining improved spatial graph convolution operator with a modified transformer self-attention operator to capture both local and global information of the joints. The spatial self-attention augmented module is used to understand the intra-frame relationships between human body parts. As far as we know, we are the first group to utilize self-attention for video anomaly detection tasks by enhancing spatial temporal graph convolution. Moreover, to validate the proposed model, we performed extensive experiments on two large-scale publicly standard datasets (i.e., ShanghaiTech Campus and CUHK Avenue datasets) which reveal the state-of-art performance for our proposed approach when compared to existing skeleton-based methods and graph convolution methods.
