The article argues that Retrieval-Augmented Generation (RAG) is only one tool in NLP, and many real-world problems—such as request classification, free‑text matching, table reading, and OCR noise cleaning—are better served by simpler, cheaper techniques. It emphasizes the importance of selecting the appropriate method for each task and highlights the engineering challenge of knowing which technique to apply.

Abstract: Word-level detectors identify unedited AI-generated text almost perfectly, but the literature documents their brittleness under rewording, and a word-l...

The article "From Words to Vectors: What Happens in Between?" explores the process of converting textual data into numerical representations, focusing on techniques such as TF-IDF and vector space models. It discusses how these representations enable text classification tasks and provides a practical overview of the underlying concepts. The piece serves as a guide for readers interested in the mechanics of text preprocessing and feature extraction for machine learning.
