D801: Machine Learning for Computer Scientists

Machine Learning for Computer Scientists is genuinely industry-aligned — built to correspond with the AWS Certified Machine Learning Engineer — Associate certification, giving graduates a professional credential angle alongside their coursework.

What D801 covers

The course provides a comprehensive introduction to foundational machine learning algorithms and applications, aligned with the AWS Certified Machine Learning Engineer — Associate (MLA-C01) certification.

Coverage spans supervised learning (linear/logistic regression, decision trees, support vector machines) and unsupervised learning (clustering, dimensionality reduction), along with model evaluation, selection, and optimization — cross validation, hyperparameter tuning, ensemble methods — using Python.

The D801 performance assessment

Expect a performance assessment requiring you to build, evaluate, and optimize a machine learning model in Python for a given dataset, using proper cross-validation and hyperparameter tuning.

Key topics in D801

• Supervised learning algorithms
• Unsupervised learning methods
• Model evaluation and hyperparameter tuning
• AWS ML certification-aligned content

Writing tips for D801

Follow the task instructions and rubric line by line

WGU performance assessments for D801 are graded against a fixed rubric — every rubric line has to be visibly addressed, usually with a labeled heading that mirrors the rubric language. Skipping a rubric point because it seems minor is the single most common reason a competent submission comes back "Not Yet Competent" for revision.

Show your work: code, reasoning, and test results, not just a final answer

WGU evaluators are trained to distinguish genuine technical work from a paraphrased summary. Include your actual code, algorithmic reasoning, and test/benchmark results, not just a description of what you built — a rubric checking technical competency wants to see the artifact and the thinking behind it.

Because WGU is self-paced, don't let "no deadline pressure" become no submission

There's no weekly due date forcing progress, which means procrastination costs more at WGU than at a traditional term-based school — a stalled task can quietly eat weeks of a term. Treat your own target date for each D801 assessment as a real deadline.

Why students seek help with D801

Students sometimes build a model without proper cross-validation, leading to overfitting that isn't caught until deployment — the course specifically wants that validation methodology demonstrated, not skipped.

How GradeEssays helps with D801

Share your ML dataset/task and rubric, and your writer will build the model with proper cross-validation and hyperparameter tuning, avoiding overfitting.

Prerequisites and program context

D801 has no listed prerequisites and sets groundwork for Deep Learning and Natural Language Processing.
