Apply Basic Prompting

Use clear instructions, constraints, and iteration to improve outputs

AI Foundations

Understanding the core concepts behind artificial intelligence

Machine Learning Models

Learn patterns from data
Adjust behavior based on examples
Handle variations and uncertainty
Example: Image recognition, language translation

Rule-Based Programs

Follow explicit instructions
Work exactly as programmed
Predictable but inflexible
Example: Calculator, traffic light system

Pattern Recognition

AI excels at finding hidden patterns in large datasets that humans might miss

Data Dependency

Models learn from examples - quality and bias in data directly affects behavior

Probabilistic Output

AI provides likely answers based on patterns, not guaranteed truth

Types of Machine Learning

Three main approaches to teaching machines

Supervised Learning

Learning with a teacher - provided correct answers during training

Examples:
• Email spam detection
• Medical diagnosis
• Image labeling

Unsupervised Learning

Finding hidden patterns - discovers structure without labeled examples

Examples:
• Customer segmentation
• Recommendation systems
• Anomaly detection

Reinforcement Learning

Learning through trial and error - improves via reward feedback

Examples:
• Game playing (chess, Go)
• Robot navigation
• Trading algorithms

Generative AI Explained

How modern AI creates human-like text and content

Key Concepts

  • Tokens: Text broken into pieces (words, parts of words)
  • Context Window: How much text the model can "remember"
  • Prompts: Your instructions and input to the model
  • Temperature: Controls randomness vs. predictability
  • Training Data: Internet text used to teach the model patterns
  • Tokenization: Break input text into small pieces
  • Context Analysis: Understand meaning and relationships
  • Pattern Matching: Compare to learned patterns from training
  • Probability Calculation: Determine likely next tokens
  • Generation: Select and output the response
  • What Generative AI Does Well

    • Explains complex topics clearly
    • Writes in different styles and formats
    • Translates between languages
    • Summarizes long documents
    • Brainstorms creative ideas

    Current Limitations

    • May generate plausible but false information
    • Can't access real-time information
    • Reflects biases from training data
    • Sometimes overconfident or verbose
    • Limited reasoning about physical world

    Understanding Model Performance

    How to read and interpret AI accuracy metrics

    Accuracy

    85%

    Overall correct predictions

    Precision

    78%

    Correct positive predictions

    Recall

    92%

    Found actual positives

    False Positives

    Model says "yes" when answer is "no" (like spam filter blocking good email)

    False Negatives

    Model says "no" when answer is "yes" (like missing actual spam)

    Context Matters

    Different errors matter more in different applications (medical vs. entertainment)

    AI in Everyday Life

    Recognizing artificial intelligence around us

    Communication

    Smart keyboards, translation, email filtering

    Ethical Considerations:
    Privacy in message analysis, translation accuracy for important communications

    Entertainment

    Streaming recommendations, content moderation

    Ethical Considerations:
    Filter bubbles, addictive design, content bias

    Commerce

    Product recommendations, fraud detection, pricing

    Ethical Considerations:
    Price discrimination, data collection, manipulation

    Essential Questions to Ask

    • What data is being collected about me?
    • How transparent is the AI decision-making process?
    • Can I appeal or correct AI-driven decisions?
    • Who is responsible when the AI makes mistakes?
    • Does this AI system treat all groups fairly?

    Basic Prompting Skills

    Practical techniques for better AI interactions

    Vague Prompts

    "Help me with this document"
    • Too general
    • No context
    • Unclear goal

    Clear Prompts

    "Summarize this 5-page report into 3 key findings for my manager"
    • Specific task
    • Clear format
    • Defined audience

    Prompt Improvement Exercise

    Key Improvements:

    Your analysis will appear here...

    Be Specific

    Replace "make this better" with "reduce to 100 words while keeping main points"

    Set Context

    Explain the audience, purpose, and any important background information

    Request Format

    Ask for bullet points, numbered lists, or specific structures

    Include Constraints

    Specify length limits, tone requirements, or things to avoid

    Ask for Reasoning

    Request step-by-step thinking or sources for verification

    Iterate & Refine

    Build on responses by asking follow-up questions or adjustments
