We continuously share large‑model know‑how, helping you master core skills—LLM, RAG, fine‑tuning, deployment—from zero to job offer, tailored for career‑switchers, autumn recruiters, and those seeking stable large‑model positions.
This article explains the role of embedding models in Retrieval‑Augmented Generation, compares the most popular 2024‑2025 open‑source embeddings and rerankers, offers concrete selection rules, shows how to read the MTEB leaderboard, and provides a structured answer framework for interviewers.
This guide shows how to translate concrete RAG project work—mixing retrieval, embedding fine‑tuning, and reranking—into concise, quantified resume bullet points that instantly signal depth to interviewers and prepare you for the detailed follow‑up questions they will ask.
The article explains how diverse user queries in a RAG‑based insurance system require intent classification, entity extraction, and multi‑path routing to choose between vector search, calculation, database lookup, or chit‑chat, and outlines practical rule‑ML‑LLM hybrid solutions with safety safeguards.
This article explains the role of memory modules in Retrieval‑Augmented Generation systems, compares short‑term and long‑term memory techniques, outlines storage and retrieval methods, discusses management strategies like forgetting and deduplication, and compares LangChain and LlamaIndex implementations for practical deployment.
This article breaks down the final‑mile challenges of Retrieval‑Augmented Generation—hallucinations, broken multi‑turn dialogue, prompt design, citation, and feedback loops—and provides concrete, layered solutions ranging from hard‑coded prompts and few‑shot examples to query rewriting, history management, post‑processing filters, and self‑check mechanisms.
This article explains why Reciprocal Rank Fusion often outperforms weighted‑sum fusion in Retrieval‑Augmented Generation, presents a three‑layer approach to keep knowledge bases timely, discusses HyDE’s cost‑benefit trade‑offs, and offers concrete interview‑ready answers for common RAG follow‑up questions.
This article provides a comprehensive guide to offline document parsing for Retrieval‑Augmented Generation, covering multi‑format extraction, layout analysis, OCR pitfalls, chunking strategies, hierarchical metadata tagging, and how these steps directly affect retrieval accuracy and overall RAG performance.
The article explains that premature tool calls in LLM agents stem from a data‑distribution bias in fine‑tuning, and it presents practical fixes such as adding non‑tool samples, enforcing a Thought chain, and using negative sampling to teach the model when to think before acting.
The article explains how loss masking in supervised fine‑tuning of large language models prevents the model from learning irrelevant tokens such as user inputs, system prompts, tool outputs, and padding, thereby focusing training on the assistant’s responses and improving performance and generalization.
The article explains how Text2SQL should be treated as a read‑only tool within an AI Agent, covering its role in function calls, dynamic schema pruning, ambiguity handling, SQL safety checks, result validation, semantic caching, and logging to build a production‑grade system.
