An Importance Aware Weighted Coding Theorem Using Message Importance Measure
Zheqi Zhu, Shanyun Liu, Rui She +3
There are numerous scenarios in source coding where not only the code length but the importance of each value should also be taken into account. Different from the traditional codi…
Storage Space Allocation Strategy for Digital Data with Message Importance
Shanyun Liu, Rui She, Zheqi Zhu +1
This paper mainly focuses on the problem of lossy compression storage from the perspective of message importance when the reconstructed data pursues the least distortion within lim…
Information Measure Similarity Theory: Message Importance Measure via Shannon Entropy
Rui She, Shanyun Liu, Pingyi Fan
Rare events attract more attention and interests in many scenarios of big data such as anomaly detection and security systems. To characterize the rare events importance from proba…
A Switch to the Concern of User: Importance Coefficient in Utility Distribution and Message Importance Measure
Shanyun Liu, Rui She, Shuo Wan +2
This paper mainly focuses on the utilization frequency in receiving end of communication systems, which shows the inclination of the user about different symbols. When the average…
How Many Samples Required in Big Data Collection: A Differential Message Importance Measure
Shanyun Liu, Rui She, Pingyi Fan
Information collection is a fundamental problem in big data, where the size of sampling sets plays a very important role. This work considers the information collection process by…
Non-parametric Message Important Measure: Storage Code Design and Transmission Planning for Big Data
Shanyun Liu, Rui She, Pingyi Fan +1
Storage and transmission in big data are discussed in this paper, where message importance is taken into account. Similar to Shannon Entropy and Renyi Entropy, we define non-parame…
