A Self-adaptive Classifier for Efficient Text-stream Processing

Naoki Yoshinaga, Masaru Kitsuregawa
2014 International Conference on Computational Linguistics  
A self-adaptive classifier for efficient text-stream processing is proposed.  ...  The proposed classifier adaptively speeds up its classification while processing a given text stream for various NLP tasks.  ...  Conclusion Aiming to efficiently process a real-world text stream (such as a Twitter stream) in real-time, a selfadaptive classifier that becomes faster for a given text stream is proposed.  ...

Self-Learning Camera: Autonomous Adaptation of Object Detectors to Unlabeled Video Streams [article]

Adrien Gaidon, Gloria Zen, Jose A. Rodriguez-Serrano (Xerox Research Center Europe, France)
2014 arXiv   pre-print
(i) detectors continuously updating themselves to efficiently adapt to streaming data sources (contrary to transductive algorithms), (ii) without any labeled data strongly related to the target data stream  ...  To that end, we propose an unsupervised, on-line, and self-tuning learning algorithm to optimize a multi-task learning convex objective.  ...  These approaches can only be applied in stationary transductive settings, and do not allow for efficient model adaptation along a particular video stream.  ...

Text Classification Techniques: A Literature Review

2018 Interdisciplinary Journal of Information, Knowledge, and Management  
The role of streaming data processing is still rarely explored when it comes to text classification.  ...  It supports state-of-the-art decision making, for example, predicting an event before it actually occurs, classifying a transaction as 'Fraudulent' etc.  ...  Self-training along with semisupervised classifier is recommended for multi-label hierarchical classification. It has also proven a better way to achieve automatic label attribution.  ...
