AI System on Native AWS - Part 8 - 即時串流 ML 與詐欺偵測
詐欺偵測是即時 ML 的極限測試:要在幾十毫秒內對每筆交易做出放行或攔截的決定,特徵要用『此刻及過去幾秒』的行為即時算出,對手還會主動規避你的規則。本篇用純 AWS 原生服務打造即時串流風控:Kinesis 收交易流、Managed Service for Apache Flink 做串流特徵、SageMaker/Fraud Detector 毫秒級評分、Neptune 圖資料庫抓詐欺團夥、DynamoDB 當線上特徵與決策存放,全部用 CDK(CloudFormation)描述,深入談串流特徵一致性、時間窗、圖偵測與規則+ML 混合決策。
AI System on Native AWS - Part 7 - 基礎模型客製化與模型治理
當通用模型不夠好、或你有大量專有資料想讓模型內化時,就得客製基礎模型。但企業真正的難題不是『怎麼 fine-tune』,而是『如何治理』——訓練資料哪來的、評估過了沒、誰核准上線、出問題能不能回溯。本篇用純 AWS 原生服務打造一條可治理的模型客製管線:RAG/Prompt/Fine-tune/蒸餾的決策框架、資料準備、Bedrock 客製模型與 SageMaker 微調、Model Registry、自動評估關卡、Model Cards 與審批工作流,全部用 CDK(CloudFormation)描述。
AI System on Native AWS - Part 5 - 生產化 MLOps 與可觀測性
前四篇蓋好了四個 AI 系統,但『能跑』跟『敢上線』之間隔著一整套 MLOps。本篇收束整個系列,講清楚 AWS 原生 AI 系統的生產化:SageMaker 的三種部署策略與藍綠/金絲雀更新、Bedrock 模型呼叫日誌與 CloudWatch/X-Ray 可觀測性、模型漂移偵測、成本治理與 tag 分帳、以及用 CDK Pipelines 做基礎設施 CI/CD。全部用 CDK(CloudFormation)描述,並附一張跨五篇的系統對照總表。
AI System on Native AWS - Part 3 - 即時個人化推薦系統
推薦系統是最經典、商業價值最直接的 AI 系統。本篇用純 AWS 原生服務打造一套即時個人化推薦:Kinesis 收即時行為、SageMaker Feature Store 管線上/離線特徵、SageMaker Endpoint 做低延遲推論、DynamoDB 當候選集與快取,並用 API Gateway + Lambda 對外服務。全部用 CDK(CloudFormation)描述,深入談 online/offline 特徵一致性、召回+排序兩階段、冷啟動與 A/B 測試。
