Outlier detection algorithm based on k-nearest neighbors-local outlier factor
The main task of outlier detection is to detect data objects which have a different mechanism from the conventional data set. The existing outlier detection methods are mainly divided into two directions: local outliers and global outliers. Aiming at the

Maintenance efficient routing in wireless sensor networks [PDF]
Communication patterns define the energy depletion profile of a wireless sensor network. In particular, routing defines which areas of the sensor field are subject to a higher traffic load. In these areas, sensor nodes deplete faster than in areas with a

Reliability of Wireless Sensor Networks [PDF]
Wireless Sensor Networks (WSNs) consist of hundreds or thousands of sensor nodes with limited processing, storage, and battery capabilities. There are several strategies to reduce the power consumption of WSN nodes (by increasing the network lifetime) and increase the reliability of the network (by improving the WSN Quality of Service).

A Keyword Detection and Context Filtering Method for Document Level Relation Extraction
Relation extraction (RE) is the core link of downstream tasks, such as information retrieval, question answering systems, and knowledge graphs. Most of the current mainstream RE technologies focus on the sentence-level corpus, which has great limitations
