Best Practices in Data Science & Machine Learning in Practice Training Course in Ghana
Classroom cohorts in Accra · live online · in-house anywhere in Ghana
Most models that look impressive in a notebook never reach production, and many that do quietly degrade because nobody planned for data quality, leakage, bias or monitoring. Ten days of hands-on labs give analysts and engineers the habits that separate a reliable, maintainable system from a one-off experiment.
The first week moves from problem framing and success metrics through data cleaning with pandas, exploratory analysis, feature engineering and baseline models in scikit-learn, with disciplined train, validation and test splitting. The second week goes deeper into cross-validation, hyperparameter tuning, gradient boosting, handling imbalanced data, model interpretability with SHAP, fairness checks, reproducible pipelines, Git, experiment tracking with MLflow, testing, containers, REST deployment and drift monitoring. A final project takes a business problem from raw data to a deployed, documented model. The programme is designed for data analysts, junior data scientists, software developers moving into machine learning, statisticians, researchers and technical leads in banks, telecoms, government, health and development organisations. Delegates attend in class, online or in-house and receive a CPD-accredited certificate. Afterwards you can plan, build, validate and hand over a model that colleagues can trust, rerun and maintain.
About this course
Organisations in every sector now invest in data science, yet many projects stall between proof of concept and daily use. The causes are rarely about algorithms. They come from vague problem definitions, inconsistent data preparation, models validated on the wrong data, undocumented code that only its author can run, and no process for noticing when performance falls. Applying sound engineering and statistical practice from the first day of a project is the most reliable way to avoid these failures.
The Best Practices in Data Science & Machine Learning in Practice Training Course follows the full lifecycle over ten days. Participants begin with framing business questions and choosing metrics, then work through data quality, exploratory analysis, feature engineering and baseline modelling in Python. Later days address rigorous evaluation, tuning, ensembles, interpretability and fairness, followed by version control, reproducible pipelines, automated tests, packaging, deployment as a service and ongoing monitoring. Responsible use of data, privacy and documentation run throughout.
Every topic is taught in a live coding lab on realistic datasets drawn from finance, health, agriculture and telecommunications. Participants build a project repository as they go, review one another's work using a shared checklist and conclude with an end-to-end capstone that is presented to a panel of facilitators.
Training Objectives
By the end of the course, participants will be able to:
- Translate a business question into a well-defined modelling task with measurable success criteria.
- Clean, validate and document datasets using reproducible pandas workflows.
- Engineer features and build baseline models before moving to complex methods.
- Evaluate models with appropriate splits, cross-validation and metrics, and avoid data leakage.
- Tune and compare algorithms including regularised regression, random forests and gradient boosting.
- Explain model behaviour with feature importance and SHAP, and test for bias across groups.
- Track experiments, version code and data, and structure projects for reuse.
- Deploy a model behind an API and monitor it for drift and performance decay.
