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 dissects Claude Code's memory system, explains why unstructured memory degrades performance, introduces four distinct memory types with concrete examples and schema, shows how to handle expiration and retrieval strategies, and provides step‑by‑step implementation code to improve agent reliability.
The article analyzes why memory extraction in LLM‑driven agents incurs cost, compares four frameworks—Claude Code, Generative Agents, MemGPT, and Mem0—detailing their trigger mechanisms, concurrency handling, and trade‑offs, and offers practical guidance for choosing the right strategy in real‑time, social, or batch‑processing scenarios.
The article debunks the myth that Java developers only need a bit of AI knowledge to succeed in LLM application roles, explaining the full engineering stack—from retrieval and prompt design to deployment and performance tuning—through real‑world examples, metrics, and interview‑ready advice.
Standard QA datasets fall short for deep research tasks because they lack the multi‑step, dynamic reasoning required; this article explains why, outlines four data‑construction techniques—SailorFog‑QA, WebFrontier, WebShaper, E2HQA—details trajectory sampling, filtering, scale considerations, and interview‑ready explanations.
This article dissects Claude Code’s Memory subsystem, explaining the distinction between Session logs and persistent Memory, the SHA‑256‑based storage layout, file indexing, four memory types, prompt injection steps, two write pathways, the ExtractionCoordinator’s coalescing strategy, and how to explain the design in interviews.
This article explains why interviewers use seemingly rote questions to probe a candidate's true grasp of concepts, contrasts memorization with genuine understanding using PPO vs GRPO, and provides a practical three‑question framework and dialogue examples to help candidates answer technical principle questions confidently.
This article explains why many candidates fail to convey their RAG projects in interviews, contrasts tool‑list versus problem‑driven presentations, and provides a four‑question framework with concrete metrics, decision‑making examples, and actionable steps to rebuild a persuasive project narrative.
This article explains how to turn simple API calls into robust, noise‑filtering tools—Search, Visit, Scholar, and Python—by adding domain blacklists, relevance scoring, query‑driven extraction, safety sandboxes, and a unified registry, ultimately boosting the success rate of LLM‑driven research agents.
This article explains how to upgrade a ReAct agent from a proof‑of‑concept to a production‑ready system by classifying tool failures, detecting repeated search loops, managing token budgets, and adding structured logging, complete with Python implementations and practical interview guidance.
This article provides a comprehensive guide to designing, implementing, and evaluating an Agent Memory module for large‑language‑model assistants, covering memory types, short‑ and long‑term storage, conflict resolution, hybrid retrieval, compliance, and practical interview answers.
