Recent innovations in Reinforcement Learning from Human Feedback (RLHF) are revolutionising how large language models are aligned with human values, blending scalability with safety to create more responsible AI systems, despite persistent challenges like bias and hallucinations. Reinforcement Learning from Human Feedback (RLHF) has emerged as a pivotal technique in training large language models (LLMs), addressing critical shortcomings of models solely reliant on next-token prediction. While pre-training equips LLMs with linguistic fluency, it does not inherently align their outputs with human values, preferences, or nuanced contextual understanding. Consequently, such models may produce harmful content, hallucinate facts, or fail to accurately…

Enterprise AI in 2026 is shifting focus from massive models to specialised, autonomous systems that enhance operational efficiency, despite adoption challenges and scepticism about business value. In 2026, the generative artificial intelligence (AI) landscape is witnessing a profound shift away from the pursuit of ever-larger models towards more specialised, right-sized…
A novel hybrid metaheuristic, AQSCA, integrates sine-cosine dynamics, Levy flights, and chaotic sequences to enhance exploration and exploitation, outperforming conventional algorithms in high-dimensional and real-world engineering problems. The Sine Cosine Algorithm (SCA), initially proposed by Mirjalili, represents a novel, population-based metaheuristic optimizer designed to solve complex real-world optimization problems through…
Shoppers and engineers are turning to advanced RAG techniques to make LLMs actually useful for real work, not just demos. This guide explains who benefits, what to change in your pipeline, and where to start so your retrieval-augmented generation setup becomes more accurate, faster, and explainable. RAG basics: Combines retrieval…
Shoppers are discovering hybrid search is the missing piece when PostgreSQL meets embeddings, and it matters because combining sparse keyword signals with dense vectors gives much better precision for exact terms, codes or dates. This guide walks through the what, why and how of hybrid sparse‑dense search with pgvector, reciprocal…
