Compressing and Querying Integer Dictionaries Under Linearities and Repetitions
IEEE Access, 2022 We revisit the fundamental problem of compressing an integer dictionary that supports efficient ${\mathsf {rank}}$ and ${\mathsf {select}}$ operations by exploiting simultaneously two kinds of regularities arising in real data: repetitiveness and ...

Complexity of Cardiotocographic Signals as A Predictor of Labor
Entropy, 2020 Prediction of labor is of extreme importance in obstetric care to allow for preventive measures, assuring that both baby and mother have the best possible care. In this work, the authors studied how important nonlinear parameters (entropy and compression)

Parallel Data Compression Techniques [PDF]
arXiv, 2023 With endless amounts of data and very limited bandwidth, fast data compression is one solution for the growing datasharing problem. Compression helps lower transfer times and save memory, but if the compression takes too long, this no longer seems viable.

Application of data compression methods to hypothesis testing for ergodic and stationary processes [PDF]
Discrete Mathematics & Theoretical Computer Science, 2005 We show that data compression methods (or universal codes) can be applied for hypotheses testing in a framework of classical mathematical statistics. Namely, we describe tests, which are based on data compression methods, for the three following problems:

Performance analysis of compression algorithms for information security: A Review [PDF]
EAI Endorsed Transactions on Scalable Information Systems, 2020 Data compression is a vital part of information security, since compressed data is much more secure and convenient tohandle. Effective data compression technique creates an effective, secure, easy communicable & redundant data.

Anti-Compression Contrastive Facial Forgery Detection [PDF]
arXiv, 2023 Forgery facial images and videos have increased the concern of digital security. It leads to the significant development of detecting forgery data recently. However, the data, especially the videos published on the Internet, are usually compressed with lossy compression algorithms such as H.264.

The relative efficiency of data compression by LZW and LZSS
Data Science Journal, 2007 We explore the use of the LZW and LZSS data compression methods. These methods or some versions of them are very common in use of compressing different types of data.
