Performance Trade-offs of Community Detection Algorithms in Dense and Sparse Network Topologies

Community detection is commonly used to uncover latent group structure in complex networks, but its effectiveness is highly dependent on the topology of the graph being analyzed. An algorithm that performs well on a dense social network may not show the same behavior on a sparse collaboration network, making it difficu...

Resource-Efficient Semantic Retrieval Optimization for Retrieval-Augmented Generation Using FAISS, Milvus, HNSW, and Product Quantization

Retrieval-Augmented Generation (RAG) enhances large language models (LLMs) by integrating external knowledge, but its performance depends heavily on efficient semantic vector search. This paper presents a deployment-oriented empirical study that systematically compares established backends and ANN configurations under...
