Reviving the Generalized Louvain Method: From Theory to Scalable Open Source

Fifteen years ago, we explored a different way to detect communities in large networks. At the time, most community detection methods focused almost exclusively on modularity maximization. Louvain-based approaches were fast, elegant, and widely adopted — but they were also structurally limited. They optimized density. Networks, however, are richer than density alone. Today, I’ve revived…

Social approval prompts more online hate!

Our lab’s latest work titled “Social Approval and Network Homophily as Motivators of Online Toxicity” was featured on The Conversation! The article discusses the phenomenon where the act of posting toxic messages on social media is driven by the attention and social approval that the poster receives from like-minded individuals. It suggests that receiving ‘likes’…

The Intricacies and Ethical Challenges of Bias in Generative Language Models

My latest work titled “Should ChatGPT be biased? Challenges and risks of bias in large language models” has been published on First Monday. In the current era of rapidly advancing artificial intelligence (AI) and machine learning (ML), generative language models like ChatGPT have become increasingly prevalent. These models, which can generate human-like text, have significant…
