What does "GSD" mean?

Table of Contents

Graph Signal Denoising (GSD) is a method used to clean up data that is organized in the form of a graph. In many cases, this data can be affected by noise, making it difficult to analyze or use effectively.

The main idea behind GSD is to improve the quality of the data by reducing this noise. It does this by adjusting the structure of the graph, which helps in making the data clearer. The process involves two steps: first, making some changes to the graph to improve the signal, and then minimizing any remaining issues to get the best possible outcome.

GSD plays a significant role in ensuring that data represented in graphs is reliable and useful for various applications.
