Project Abstract & Technical Scope

This project introduces an end-to-end, production-ready machine learning framework for Machine Learning For Customer Churn Prediction SaaS. Within real-world operational environments, systems face severe obstacles including team-level multi-tenant dynamics, contract seasonality, and silent executive disengagement. The objective of this work is to implement a robust, leak-free computational pipeline that translates raw inputs into deterministic, high-confidence decision metrics.

The system ingests and processes records sourced from daily active user (DAU/MAU) ratios, core feature event counts, API usage volume, and support ticket escalation trends. Raw attributes undergo automated data sanitization, multivariate imputation, distribution rebalancing, and outlier filtering. Continuous numerical features are scaled using robust statistical scaling techniques, while categorical, spatial, and temporal attributes receive cyclical encoding, high-cardinality target transforms, or dense embeddings.

Modeling evaluates diverse algorithmic paradigms: LightGBM Classifier, Random Forest, ElasticNet Logistic Regression, Multi-Layer Perceptron. Rigorous validation protocols employ stratified, temporal, or grouped cross-validation to prevent train-test contamination. Hyperparameter optimization is systematically executed via Bayesian search strategies (Optuna), targeting optimization of PR-AUC, F1-Score, Net Revenue Retention (NRR) Impact, Lead Time to Renewal Alert rather than uninformative global accuracy.

To ensure practical viability and regulatory transparency, global and local feature contributions are derived using TreeSHAP and Partial Dependence profiles. The winning configuration is serialized into portable ONNX format and served via an asynchronous FastAPI microservice equipped with telemetry logging for real-time concept drift detection.
