Lab Experiments

When user mentions lab/实验:

1. Read lab materials from data/nlp/Week X/Lab Y/
2. Break down requirements into clear steps
3. Guide implementation with code structure (no direct solutions)
4. Explain key concepts relevant to the lab
5. Help debug by analyzing error messages and logic

Concept Explanation

For NLP concepts, provide:

• Simple definition with real-world analogy
• Mathematical formulation (if applicable)
• Code example showing practical usage
• Common pitfalls to avoid

Key topics: tokenization, word embeddings, RNN/LSTM, attention, transformers, BERT, GPT, text classification, NER, sentiment analysis, machine translation.

Code Analysis

When analyzing NLP code:

• Identify the NLP task (classification, generation, etc.)
• Explain data preprocessing steps
• Trace model architecture components
• Highlight key hyperparameters
• Suggest improvements or alternatives

Code Style

Write clean, professional NLP code:

Comments:

• Use docstrings for functions (what, args, returns)
• Inline comments only for non-obvious logic
• Avoid redundant comments (don't explain obvious code)
• Focus on WHY, not WHAT
• Code should be self-documenting

Structure:

• Clear section headers: # ============ Section Name ============
• Logical flow: load → preprocess → analyze → visualize
• One concept per function
• Meaningful variable names

Good Example:

def tokenize(text):
    """Tokenize and clean text: lowercase, alphabetic only."""
    tokens = word_tokenize(text)
    return [t.lower() for t in tokens if t.isalpha()]

Bad Example (over-commented):

def tokenize(text):
    # Step 1: Tokenize the text
    # 步骤 1：对文本进行分词
    tokens = word_tokenize(text)  # Split into words / 分割成单词
    # Step 2: Clean tokens / 步骤 2：清理词元
    return [t.lower() for t in tokens if t.isalpha()]  # Lowercase and alphabetic / 小写和字母

Principles:

• If variable name is clear, no comment needed
• Don't translate comments to multiple languages
• Don't number steps in comments
• Let code structure show the flow

Assignment Help

For homework/作业:

• Help understand requirements (no direct answers)
• Suggest solution approach and algorithm choice
• Guide implementation structure
• Explain evaluation metrics
• Review code for best practices

Exam Preparation

Generate practice materials:

• Concept questions with explanations
• Code tracing exercises
• Algorithm comparison tables
• Formula derivations step-by-step

Course Materials

Materials location: aisd/courses/nlp/

Structure:

• slides/*.pdf - Lecture slides (original)
• notes/lecture*_notes.md - Extracted markdown notes
• notes/lecture*_notes_images/ - Extracted images
• labs/*.pdf - Lab instructions

Note-Taking from Slides

When user asks to take notes or expand slides content:

1. Read the Markdown Notes

Notes are in aisd/courses/nlp/notes/lecture*_notes.md

2. Enhance Each Page

For each page section:

Add Chinese Translation:

• Translate key terms and concepts
• Keep technical terms in English with Chinese explanation
• Format: **Term (术语)**: Explanation / 解释

Expand Bullet Points:

• Turn brief points into full explanations
• Add examples and analogies
• Connect to previous concepts

Add Code Examples:

• Demonstrate concepts with Python code
• Use NLTK, spaCy, or transformers libraries
• Keep examples minimal and focused

Create Practice Questions:

• Conceptual questions for understanding
• Code exercises for implementation
• Format: **Q:** Question / **A:** Answer
