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 how Deep Research extends traditional Retrieval‑Augmented Generation by adding autonomous planning, multi‑step search, self‑correction, and long‑context synthesis to enable AI agents that can generate comprehensive industry analysis reports.
This article examines MinerU’s strengths and nine critical shortcomings—such as reading order errors, split tables, merged cells, OCR misrecognition, formula handling, heading hierarchy loss, output inconsistency, hardware limits, and licensing issues—and provides concrete improvement strategies and interview‑ready talking points for engineers.
This article breaks down the end‑to‑end retrieval function used in a RAG system, detailing each of the five stages—from request construction, hybrid vector + BM25 search, RRF fusion, cross‑encoder reranking, to threshold filtering—and provides concrete Python code, parameter choices, and performance insights.
This article examines MinerU's strengths and nine critical shortcomings—such as layout order errors, cross‑page table splits, merged‑cell failures, OCR misrecognition, and licensing issues—and provides concrete improvement strategies, interview‑ready resume bullets, and practical response frameworks for engineers.
This article explains why simple prompt‑based citation is insufficient for Retrieval‑Augmented Generation, introduces a sentence‑level attribution pipeline, combines semantic similarity with NLI verification, and presents practical hallucination detection and structured JSON output to ensure answer reliability.
Chunk splitting, a critical yet often overlooked step in RAG pipelines, dramatically impacts retrieval recall and LLM output quality; this guide walks through three evolution stages—from naive fixed‑length splits to sentence‑aware overlaps and finally semantic, structure‑driven segmentation—complete with code, experiments, and practical pitfalls.
This article outlines a full‑stack RAG architecture—offline parsing, query understanding, online retrieval, and context generation—explains six critical module interactions, and provides a concise interview framework for presenting the design from start to finish.
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.
