The precision of the conventional user identification algorithm is not satisfactory because it ignores role user-generated data in identity matching. In this paper, we propose a frequent pattern mining-based cross-social network that analyzes personalized manner. We adopt posterior probability-based information entropy weight allocation method improves rate and recall compared to empirical method. extensive simulations are provided demonstrate proposed can enhance rate, as well F-Measure (F1).

Agile Earth Observing Satellite (AEOS) scheduling problem consists of selecting a subset tasks and developing observation plans for set agile satellite resources with the purpose maximizing total reward arranged mission observations. This has attracted much attention in recent years since AEOS is new generation being developed all over world. Due to its NP-hardness, heuristic methods are widely adopted when solving (AEOSSP). In this paper, we propose temporal conflict network-based algorithm...

Social networking is an interactive Internet of Things. The symmetry the network can reflect similar friendships users on different social networks.

Across identification (ASNUI) can help perfect information, personalized service recommendation, mining, as well provide support scientific research. This paper first...

This paper considers a multi-depot heterogeneous vehicle routing problem (MDHVRP) with time windows, which is very crucial for hazardous materials transportation. For this reason, we formalize as multi-objective MDHVRP optimization model, where the actual load dependent risk of transportation considered.

Distant supervision relation extraction is an effective method to extract the real between entities from unstructured corpus. However, affected by hypothesis of distant mechanism, model often faces disturbance mislabeled data and noise samples. In order alleviate above problems improve performance, we propose a framework based on Bert-based pre-trained models, Bert for Relation Extraction (BRE). BRE uses BERT as feature extractor loads parameters fine-tuning. It integrates external semantic...

Due low precision user identification many-to-many mechanism identification, random forest confirmation algorithm based on stable marriage matching...

In this paper, we propose an adaptive single differential coherent detection (SDCD) scheme for the binary phase shift keying (BPSK) signals in IEEE 802.15.4 Wireless Sensor Networks (WSNs). particular, residual carrier frequency offset effect (CFOE) is adaptively estimated, with only linear operation, according to changing channel conditions. It was found that (CFO) and chip signal-to-noise ratio (SNR) conditions do not need a priori knowledge. This partly benefits from combination of...
