This paper is focusing on research short-term based data Shanghai, China. Firstly, time series mining technology was studied also its disadvantages such as meteorological conditions were not taken into consideration pointed out. Secondly, we analyzed most competitive method existing methods that taking account,...

Querying both structured and unstructured data has become a new paradigm in analytics recommendation. With data, such as text videos, are converted to high-dimensional vectors queried with approximate nearest neighbor search (ANNS). State-of-the-art database systems implement vector plugin the relational query engine, which tries utilize ANN index enhance performance. After investigating broad range of hybrid queries, we find that designs may miss potential optimization opportunities achieve...

Outsourcing spatial databases to the cloud provides an economical and flexible way for data owners deliver users of location-based services. However, in database outsourcing paradigm, third-party service provider is not always trustworthy, therefore, ensuring query integrity critical. In this paper, we propose efficient road network k-nearest-neighbor verification technique which utilizes Voronoi diagram neighbors prove results. Unlike previous work that verifies results Euclidean space, our...

Aggregate nearest neighbor (ANN) query returns a common interesting data object that minimizes an aggregate distance for multiple points. In this paper, we propose novel approach to efficiently process ANN queries in road networks. This includes two processes: initializing and pruning process, which are both based on computing kNN of points network Voronoi diagram. Experimental results show our outperforms existing approaches response time page accesses.

In the environment of Mobile Ad-hoc Networks (MANETs), devices can collaborate under service-oriented architecture (SOA). However, as MANETs are infrastructure-less, may move randomly and join leave network at any time which leads to a permanently changing topology network. What adds unpredictability is limited resource nodes, including battery power, processing capacity memory limit common problems for mobile devices. All these features pose potential risk failure process service execution....

A Natural Language (NL) Interface to Databases (NLIDB) aims help end-users access databases. State-of-the-art approaches primarily construct language translation models convert NL queries SQL queries. While these exhibit good performance on NLIDB benchmarks, the accuracy seems have stalled at between 70%-75%, and most erroneous translations happen with complex that require an understanding of structure semantics specific a database. This paper proposes Generate-And-Rank approach called Gar....

Wireless broadcast provides a scalable and secure spatial data dissemination approach for geographical applications in wireless mobile environments. Among various location-based services, the shortest path query on road networks is one of most popular essential services our daily life. In this paper, we propose an energy-efficient scheme air processing networks, which leverages elaborate index called BagIndex based upon novel Hilbert-based heuristic tree decomposition networks. Experimental...

Indexing is a core technique for accelerating predicate evaluation in databases. After many years of effort, the indexing performance has reached its peak on existing hardware infrastructure. We propose to use ray tracing (RT) cores move and efficiency another level by addressing following technical challenges: (1) lack an efficient mapping job (2) poor heavy imbalanced load when processing skewed datasets. These challenges set obstacles effectively exploiting RT evaluation. In this paper,...

In a Network Function Virtualization (NFV) system, network functions (NFs) are implemented on general-purpose hardware, including CPU, GPU, and FPGA. Studies have shown that there is no one-size-fits-all processor, as each processor demonstrates performance advantages to implement certain types of NFs. With more processors such GPUs being deployed in data center servers, the best practice build high-performance NFV service chain should employ available heterogeneous processors. However,...

Approximate Nearest Neighbor Search (ANNS) is a fundamental and critical component in many applications, including recommendation systems large language model-based applications. With the advancement of multimodal neural models, which transform data from different modalities into shared high-dimensional space as feature vectors, cross-modal ANNS aims to use vector one modality (e.g., texts) query retrieve most similar items another images or videos). However, there an inherent distribution...

Lucene and relational database (RDB) are the two types of most popular back-end toolkits for Web applications nowadays, which mainly used to store query data. However, it is often difficult users developers make a decision choose or RDB as their data repository, since they have only conceptual understanding on difference between them. And detailed performance comparison absent yet. In this paper, we an empirical study by using experiments common test set. The experimental results show that...

IP traceback is one of the most effective techniques to defeat denial-of-service attacks and distributed attacks. And based on previous research, available probabilistic packet marking (PPM) schemes have more advantages than other techniques. But traditional too low packets utilization. In this paper, a new distributed-log-based scheme (DLS), which combines PPM logging techniques, proposed utilize sufficiently. And, theoretical analysis simulation results proven that can converge quickly...

Outsourcing spatial databases, including both road networks and points of interest, to a third party Cloud service provider has attracted much attention from individual business data owners. With popularity mobile devices, providing instant reliable location-based services smartphones tablets been major means delivering real-world users. Therefore, ensuring query integrity in database outsourcing paradigms is critical. In this paper, we propose novel network k-nearest-neighbor verification...

Service-oriented architecture is an important way for collaboration in mobile ad-hoc networks (MANETs). Yet, since MANETs are infrastructure-less, the traditional service discovery approaches will produces large amount of broadcast request packets which may cause a storm. In addition, due to dynamic network topology and limited energy devices, invocation services that discovered by has high possibility failure MANETs. this paper, we propose novel lightweight reliable approach based on...
