AI/ML-Driven Omni-Channel CVM Transformation

The process begins with AWS Glue, which orchestrates crawler jobs to extract data and store it in Amazon S3, forming the foundational data lake. This data is subsequently utilized by the Amazon SageMaker Feature Store, a centralized hub that maintains curated data for ML development.

Within the S3 buckets, the data undergoes preprocessing tailored to the needs of XGBoost and TabNet models. This step is crucial for optimizing the performance of the machine learning algorithms and is part of the MLOps pipelines that ensure operational efficiency. Following preprocessing, the data is channeled into the training phase for distinct models, each one specific to a particular brand. Post-training, these models are registered in the SageMaker Model Registry. This registration is a governance mechanism that tracks versions and maintains the lineage of models.

Once registered, the models' artifacts are deployed to create inference endpoints. These endpoints serve as scalable and secure channels for real-time predictions.

Concurrently, for inference purposes, a Linear Model runs on AWS Lambda. This serverless component is responsible for invoking the aforementioned endpoints to retrieve individual inferences. It performs a linear weighted computation that integrates two distinct scores: Customer Value and Business Value. The latter is retrieved from a DynamoDB table, ensuring low-latency access to this pivotal business metric. For augmented decision-making, additional information such as promotional data can be incorporated to refine the inference outputs.

At the forefront of this architecture lies Amazon API Gateway, which acts as the interface for external inference requests. By channeling these requests to the AWS Lambda function, it facilitates a seamless and managed entry point, thereby completing this robust machine learning ecosystem.
