This curriculum spans the full lifecycle of a production binary classification system, equivalent to a multi-workshop technical advisory engagement for deploying and maintaining high-stakes models in regulated environments.

Module 1: Problem Framing and Business Alignment

Define classification thresholds based on business cost matrices (e.g., false positive vs. false negative costs in fraud detection).
Select target variables that are measurable, stable over time, and aligned with operational decision points.
Determine whether binary classification is appropriate versus multi-class or regression alternatives given business outcomes.
Negotiate label definitions with domain stakeholders to ensure consistency (e.g., what constitutes a "churned" customer).
Assess feasibility of model deployment by evaluating downstream system integration requirements early in the project lifecycle.
Document data lineage and decision logic for auditability in regulated environments (e.g., credit scoring).
Establish feedback loops to capture post-deployment outcome data when ground truth is delayed (e.g., loan defaults).
Conduct feasibility analysis to determine if sufficient historical labeled data exists or must be actively collected.

Module 2: Data Acquisition and Quality Assurance

Implement data validation rules to detect schema drift in production data pipelines (e.g., missing features or type mismatches).
Design sampling strategies to handle class imbalance during training while preserving real-world prevalence for evaluation.
Quantify missing data patterns and choose imputation methods based on mechanism (MCAR, MAR, MNAR) and feature importance.
Integrate data from disparate sources with inconsistent identifiers using probabilistic matching techniques.
Monitor feature staleness and latency in real-time data feeds to prevent model degradation.
Apply data profiling to detect outliers and validate feature distributions against domain expectations.
Enforce data retention policies that comply with privacy regulations while preserving model retraining capability.
Version raw datasets and track changes to support reproducibility across model iterations.

Module 3: Feature Engineering and Transformation

Encode categorical variables using target encoding with smoothing to prevent overfitting on rare categories.
Apply log or Box-Cox transformations to skewed numerical features to improve model assumptions.
Construct time-based features (e.g., recency, frequency, time since last event) from transactional data.
Generate interaction terms based on domain knowledge or statistical significance testing.
Bin continuous variables only when interpretability is required and performance loss is acceptable.
Implement feature scaling methods (e.g., standardization, robust scaling) consistently across training and inference.
Design rolling window aggregations for time-series features with appropriate lag and decay parameters.
Validate feature leakage by ensuring all transformations use only information available at prediction time.

Module 4: Model Selection and Training Strategy

Compare logistic regression, random forest, gradient boosting, and SVM based on data size, dimensionality, and interpretability needs.
Select evaluation metrics (e.g., AUC-ROC, precision-recall, F1) based on class imbalance and business priorities.
Configure early stopping in iterative models using a held-out validation set to prevent overfitting.
Perform nested cross-validation to obtain unbiased performance estimates during hyperparameter tuning.
Train multiple candidate models in parallel using automated pipelines to reduce time-to-deployment.

Module 5: Model Evaluation and Validation

Construct confusion matrices on a holdout test set and interpret results in context of business cost structure.
Analyze precision-recall curves when class imbalance renders ROC curves misleading.
