The client is a global staffing solutions provider aiming to improve efficiency and decision-making in their talent acquisition and allocation processes. Their goal is to leverage data-driven tools to streamline operations and match candidates to roles with higher precision.
About the Client:
Our task was to develop a custom recommender system to optimize staffing processes. The system needed to integrate specific business rules and provide transparency in decision-making through explainable AI. It aimed to rank and recommend candidates efficiently while adapting to ongoing changes in business processes.
About the Project
Challenges & Objectives
Challenges:
Complex Business Rules: Incorporating unique rules and restrictions into the model while maintaining flexibility.
Data Drift: Adapting to frequent changes in candidate profiles and job requirements.
Explainability: Ensuring the system provided understandable reasons for each recommendation.
Objectives:
Build a scalable recommendation engine that ranks candidates effectively.
Integrate an explainability layer for transparency and user trust.
Develop mechanisms to detect and handle data drift dynamically.
Implementation
01
Data Flow and Preprocessing:
Designed data pipelines using AWS S3, Redshift, and Kinesis for real-time data ingestion.
Processed data with Pandas, Numpy, and Scikit-Learn to prepare tabular datasets for modeling.
02
Model Development:
Created a ranking algorithm centered on a Deep Neural Network (DNN) with a custom multi-headed loss function.
Incorporated penalties for feedback from various environmental factors to improve recommendation accuracy.
Designed explainability layers to provide insights into each recommendation using MLFlow.
03
Data Drift Management:
Implemented detection and handling mechanisms to identify and adapt to data changes.
Utilized tools like Optuna for hyperparameter optimization and enhanced model resilience.
04
System Deployment:
Containerized the solution using Docker and deployed it on AWS Sagemaker for scalability.
Integrated Redis for real-time model inference and Kafka for communication between services.
