Whole Time Series Data Streams Clustering: Dynamic Profiling of the Electricity Consumption

Krzysztof Gajowniczek, Marcin Bator, Tomasz Ząbkowski
2020 Entropy  
Despite the proposal of many clustering techniques applicable for grouping the observations of a single data stream, only a few of them are focused on splitting the whole data streams into the clusters  ...  Time series data streams have their own specifics in terms of the data processing and data analysis because, usually, it is not possible to process the whole data in memory as the large data volumes are  ...  Due to that in this article we focus on multiple time series data streams clustering, as this is one of the most important challenge in data stream mining.  ...

Incremental and Adaptive Feature Exploration over Time Series Stream

Jingwei Zuo, Karine Zeitouni, Yehia Taher
2019 2019 IEEE International Conference on Big Data (Big Data)  
Processing such type of data requires combining techniques in both communities of Time Series (TS) and Data Streams.  ...  Classical data stream analysis are biased towards vector or row data, where each attribute is independent to train an adaptive learning model, but rarely considers Time Series as a stream instance.  ...  To fill the gap between Time Series Classification and data streams processing, in this paper, we propose a TS stream learning algorithm, where TS features and models can be updated with consideration  ...
