About the Scikit-learn Test
You’ll be evaluated across four key areas:
Preprocessing & Feature Engineering
Demonstrate proficiency with transformers likeStandardScaler,OneHotEncoder, andLabelEncoder. Apply imputation, normalization, and feature selection techniques to prepare data effectively for model training.Supervised Learning: Regression & Classification
Implement models such as Linear Regression, Logistic Regression, Decision Trees, Random Forests, SVMs, and Gradient Boosting. Understand their use cases, hyperparameters, and performance trade-offs.Unsupervised Learning & Model Evaluation
Apply clustering (K-Means, DBSCAN) and dimensionality reduction (PCA) techniques. Evaluate model performance using metrics like accuracy, precision, recall, F1-score, ROC-AUC, silhouette score, and cross-validation.Pipelines, Model Selection & Tuning
Build reproducible workflows withPipelineandColumnTransformer, and optimize models usingGridSearchCV,RandomizedSearchCV, and cross-validation strategies for best-fit hyperparameter tuning.
This is where machine learning meets practicality — proving you can turn data into insights and models into production-ready tools.
