Toward Budgeted Online Kernel Ridge Regression on Streaming Data

open access: yesIEEE Access, 2019
“Concept drift”makes learning from streaming data fundamentally different from traditional batch learning. Focusing on the regression task on streaming data, this paper presents an efficient online learning algorithm, i.e., budgeted online ...

Evaluation of recommender systems in streaming environments [PDF]

open access: yes, 2015
Evaluation of recommender systems is typically done with finite datasets. This means that conventional evaluation methodologies are only applicable in offline experiments, where data and models are stationary.

Annotations in Data Streams [PDF]

open access: yesACM 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”

Research and Application of an Online Train ConditionMonitoring Method Based on Streaming Data

open access: yesKongzhi Yu Xinxi Jishu, 2021
In order to detect the online status of trains in real time, traditional threshold detection methods can only make judgments on the status of equipment or systems based on numerical performance, while ignoring the train health status changes reflected in

Streaming Data Classification Based on Hierarchical Concept Drift and Online Ensemble

open access: yesIEEE Access, 2023
In order to improve the performance of online learning in the real-time distribution of streaming data, a streaming data classification algorithm based on hierarchical concept drift and online ensemble(SCHCDOE) is proposed in this paper.
