Agentic RAG Failure Modes: Retrieval Thrash, Tool Storms, and Context Bloat (and How you can Spot Them Early)

fails in predictable ways. Retrieval returns bad chunks; the model hallucinates. You fix your chunking and move on. The debugging surface is small since the architecture is straightforward: retrieve once, generate once, done. Agentic...

Understanding Context and Contextual Retrieval in RAG

In my latest post, I how hybrid search will be utilised to significantly improve the effectiveness of a RAG pipeline. RAG, in its basic version, using just semantic search on embeddings, will be...

Retrieval for Time-Series: How Looking Back Improves Forecasts

Helps in Time Series Forecasting All of us understand how it goes: Time-series data is hard. Traditional forecasting models are unprepared for incidents like sudden market crashes, black swan events, or rare weather patterns....

GraphRAG in Practice: The way to Construct Cost-Efficient, High-Recall Retrieval Systems

article, , I outlined the core principles of GraphRAG design and introduced an augmented retrieval-and-generation pipeline that mixes graph search with vector search. I also discussed why constructing a wonderfully complete graph—one which...

Construct an Over-Engineered Retrieval System

you’ll encounter when doing AI engineering work is that there’s no real blueprint to follow. Yes, for probably the most basic parts of retrieval (the “R” in RAG), you'll be able to chunk documents,...

The right way to Perform Agentic Information Retrieval

is a crucial task that's critical to attain, with the vast amount of content available today. An information retrieval task is, for instance, each time you Google something or ask ChatGPT for a...

Tips on how to Evaluate Retrieval Quality in RAG Pipelines (Part 3): DCG@k and NDCG@k

: 👉 👉 of my post series on retrieval evaluation measures for RAG pipelines, we took an in depth have a look at the binary retrieval evaluation metrics. More specifically, in Part 1, we went...

Is RAG Dead? The Rise of Context Engineering and Semantic Layers for Agentic AI

Introduction Retrieval-Augmented Generation (RAG) could have been obligatory for the primary wave of enterprise AI, but it surely’s quickly evolving into something much larger. Over the past two years, organizations have realized that simply retrieving...
