Many applications generate data streams where online analysis needs are essential. In this context, pattern mining is a complex task because it requires access to all data observations. To overcome this problem, the state-of-the-art methods maintain a data sample or a compact data structure ...
In order to evaluate the efficiency of the proposed approach, we carried out experiments on real electric power consumption data streams provided by EDF (Électricité de France).论文关键词:Clustering, Data streams, Sampling, Sensor network
Modern telecommunication networks work on the transmission method of common data streams in which data bursts consisting of packets that further consist of particular bits are multiplexed from various traffic sources. The larger amount of data is transmi
We consider SRS on continuously arriving data streams and statically stored data sets. We present a tight lower bound showing that any streaming algorithm for SRS over the entire stream must have, in the worst case, a variance that is \\(\\varOmega (r)\\) factor away from the optimal, ...
sampling in some applications—queries with relatively low selectivity,outlier detection in large multidimensional data sets,and clustering over data streams with skewed Zipf distribution,the importance of need for using biased sampling methods in these scenarios is fully dissertated.In addition to ...
In time series databases, streaming refers to the computation and processing of real-time data streams, allowing for immediate calculation results as data arrives. Through streaming, we can process data in real time, performing operations such as downsampling, aggregation, filtering, etc., thereby ...
igneous image downsample gs://my-lab/data --mip 0 --queue ./my-queue igneous execute ./my-queue igneous --help For those that have been using Igneous a long time, igneous execute can replace python igneous/task_execution.py. Capabilities You can find the following tasks in igneous/tasks...
Zoned Storage and ZNS SSDs are set to revolutionize storage and system architectures for next generation heterogeneous computing systems. The new architectures will expand the value of SSDs and include sequential data streams in applications such as persistent key-value storage for data, metadata, an...
