D803: Natural Language Processing

Natural Language Processing takes deep learning into the specific domain of human language — from basic text preprocessing through the transformer architectures that power modern language AI.

What D803 covers

The course offers in-depth exploration of modern data-driven NLP techniques, progressing from basic text preprocessing to advanced ML models tailored for NLP tasks.

Topics include sentiment analysis, named entity recognition, machine translation, and advanced neural network architectures — RNNs, LSTM, and transformers — with industry-standard tools and project-based learning.

The D803 performance assessment

Expect a performance assessment requiring you to build an NLP solution (such as sentiment analysis or named entity recognition) using an appropriate neural network architecture, with project-based documentation.

Key topics in D803

• Text preprocessing methods
• Sentiment analysis and named entity recognition
• Machine translation
• RNN, LSTM, and transformer architectures

Writing tips for D803

Follow the task instructions and rubric line by line

WGU performance assessments for D803 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 D803 assessment as a real deadline.

Why students seek help with D803

Students sometimes choose an architecture (like a simple RNN) that's outdated for the specific NLP task when transformers would perform better — matching the architecture to the task's actual requirements matters for the rubric.

How GradeEssays helps with D803

Share your NLP task and rubric, and your writer will build the solution using an architecture genuinely well-matched to the task's requirements, with proper documentation.

Prerequisites and program context

D803 recommends completing AI and ML Foundations, Machine Learning for Computer Scientists, and Deep Learning before this course.
