Energy-Efficient Retrieval-Augmented Generation: A Systematic Review of Retrieval, Reranking, Caching, and Context-Management Strategies

Retrieval-Augmented Generation (RAG) has become a standard paradigm for grounding large language models (LLMs) in external knowledge, but typical deployments introduce substantial energy, latency, and cost overhead due to expensive retrieval and context-processing pipelines. Recent work in "Green AI" and sustainable ma...

Explainable Hybridized Machine Learning for Prediction of Compressive Strength of Fly-Ash based Geopolymer Concrete

This study utilizes robust machine learning (ML) techniques to predict compressive strength of fly-ash-based geopolymer concrete (GPC), a sustainable replacement for traditional concrete. Popular ensemble models, specifically Random Forest (RF) and Extreme Gradient Boosting (XGB), were taken as base models and were hyb...
