Capstone: End-to-End Sentiment Analyzer
A capstone forces you to integrate preprocessing, features, models, and evaluation into one deliverable you can show and defend.
Learn it
You will pick a real dataset (e.g. product/movie reviews or disaster tweets), build a TF-IDF + logistic-regression baseline, then fine-tune a Hugging Face transformer on the same data. You will compare metrics, do error analysis, and package the best model behind a simple predict function or demo.
By the end you’ll be able to
- Ship a complete NLP pipeline from raw text to predictions
- Compare a classical baseline against a fine-tuned transformer
Free resources
Practice
Build both models on one dataset, produce a comparison table (accuracy/F1/latency), and write a short error analysis of 10 mistakes.
Build it — your output
A documented repo/notebook with a baseline, a fine-tuned transformer, a metrics comparison, error analysis, and a runnable predict() demo.
Prove it — check yourself
You’re ready to move on when you can honestly say yes to each:
- Justify which model you would deploy and why
- Explain two concrete failure modes from your error analysis
- Reproduce your pipeline end-to-end from raw text to a prediction
Do it with AI
Use a free AI tool as your tutor and pair-programmer. Copy a prompt below into Claude, ChatGPT, or Gemini (for building, try Cursor or Copilot).
The habit: Try it yourself first — a little struggle is where the learning actually happens. Then ask for a hint before the answer — never copy blindly.
- Understand itClaude / ChatGPT / Gemini
I'm a beginner learning "Capstone: End-to-End Sentiment Analyzer". Explain it in simple terms with a real-world analogy, then ask me ONE question to check my understanding — don't reveal the answer.
- PracticeClaude / ChatGPT / Gemini
Give me 3 short practice problems on "Capstone: End-to-End Sentiment Analyzer" (my goal: ship a complete nlp pipeline from raw text to predictions), from easy to hard. Don't include the solutions yet — I'll try them first, then ask you to check.
