Annotations in Data Streams [PDF]
ACM Transactions on Algorithms, 2014 The central goal of data stream algorithms is to process massive streams of data using sublinear storage space. Motivated by work in the database community on outsourcing database and data stream processing, we ask whether the space usage of such algorithms can be further reduced by enlisting a more powerful “helper”

Proceedings of the 9th International Conference on Cloud Computing and Services Science, 2019 Nowadays many applications require to analyse the continuous flow of data produced by different data sources before the data is stored. Data streaming engines emerged as a solution for processing data on the fly. At the same time, computer architectures have evolved to systems with several interconnected CPUs and Non Uniform Memory Access (NUMA), where

Dynamic Data Streaming for an Appliance [PDF]
Proceedings of the 8th International Conference on Data Science, Technology and Applications, 2019 Many applications require to analyse large amounts of continuous flows of data produced by different data sources before the data is stored. Data streaming engines emerged as a solution for processing data on the fly. At the same time, computer architectures have evolved to systems with several interconnected CPUs and Non Uniform Memory Access (NUMA ...

Incident Retrieval and Recognition in Video Stream Using Wi-Fi Signal
IEEE Access, 2021 Retrieving incidents from video stream plays an important role in many computer vision applications. However, most video surveillance system can neither recognize incidents nor support content-based retrieval before the video stream is saved into files ...

Variability in Data Streams [PDF]
Proceedings of the 35th ACM SIGMOD-SIGACT-SIGAI Symposium on Principles of Database Systems, 2016 We consider the problem of tracking with small relative error an integer function $f(n)$ defined by a distributed update stream $f'(n)$. Existing streaming algorithms with worst-case guarantees for this problem assume $f(n)$ to be monotone; there are very large lower bounds on the space requirements for summarizing a distributed non-monotonic stream ...

FlexSketch: Estimation of Probability Density for Stationary and Non-Stationary Data Streams
Sensors, 2021 Efficient and accurate estimation of the probability distribution of a data stream is an important problem in many sensor systems. It is especially challenging when the data stream is non-stationary, i.e., its probability distribution changes over time ...
