Making clusterings fairer by post-processing: algorithms, complexity results and experiments

While existing fairness work typically focuses on fair-by-design algorithms, here we consider making a fairness-unaware algorithm’s output fairer. Specifically, we explore the area of fairness in clustering by...

Towards Description of Block Model on Graph

Existing block modeling methods can detect communities as blocks. However it remains a challenge to easily explain to a human why nodes belong to the same block. Such a description is very useful for answering wh...

Keyless dynamic optimal multi-bit image steganography using energetic pixels

Steganography plays an important role to hide data in apparently innocuous media (e.g., image, audio, video, text, etc.). Since most of the steganographic algorithms do not consider the image content while loc...
