Week 01: LLM Review

Introduction to Large Language Models and their applications in data analysis

Learning Objectives

By the end of this session, students will:

Understand core concepts of large language models (LLMs)
Distinguish between “Cyborg” and “Centaur” approaches to AI collaboration
Experience the “jagged frontier” of LLM capabilities through hands-on practice
Critically assess capabilities and limitations of AI tools in academic contexts

Preparation / Before Class

📚 No Required Reading

This is Week 1 - come ready to explore and discuss!

Reflection Preparation:

Think about your current experience with AI tools (if any)
Consider examples where you’ve encountered AI in your work/studies
Identify one data analysis task you find time-consuming or repetitive

Optional Background:

Ethan Mollick: “Co-Intelligence: Living and Working with AI” (Chapters 1-2)

Class Material

📊 Core LLM Concepts (60 min)

Slideshow: LLM Concepts and Applications

Key Topics Covered:

What are LLMs? Statistical models predicting next tokens from massive training data
The Transformer Revolution: How 2017’s “Attention is All You Need” changed everything
Context Windows: why this matters for data analysis
Training Process: Resources and human feedback
Collaborative Frameworks: How to integrate human and AI work

🔧 Hands-on: Data search (15 min)

Example

Try this in a chat

Get me an income dataset by planning regions (county) in Connecticut for 2023. Present the results as a table I can copy and edit..

Now try find the actual data and compare.
Try multiple times in different models
Try modifying the prompt to be more specific or different

Discussion Questions

End of Week Reflection:

Personal AI Experience: How have you already incorporated AI into your routine? Which model feels most natural to you?
Error Management: How do you currently deal with AI hallucinations or imperfect answers? What strategies emerged during the FT graph exercise?
The Jagged Frontier: What tasks do you expect AI to excel at? Where do you think it will struggle? Did the visualization exercise match your expectations?

Assignment

Assignment 1: Reproduce the FT Graph

Due: Sunday 23.55 before Week 2 (on moodle)

AI Model Selection Guide

Academic Integrity and AI use

Course Philosophy:

AI as Assistant: Use AI to enhance your capabilities, not replace your thinking
Maintain Authority: You remain responsible for all outputs and interpretations
Verify Everything: Always validate AI suggestions, especially statistical claims
Document Usage: Keep track of how AI helped – to learn (and for transparency)

Red Lines:

Never submit unverified AI output as your own work
Always understand the analysis you’re presenting
Avoid over-reliance on AI for critical thinking or interpretation (you be you)

The Goal:

Become a more capable data analyst who can leverage AI tools effectively while maintaining scientific rigor.

Next Week:

Week 2 - Data Discovery and Documentation where we’ll use AI to understand and document complex datasets.

Some personal comments on AI and this class

I needed to rewrite, edit the slideshow frequently. Bloody hell, this course material is tricky. (While Gosset’s t-test has been around since 1908…)
It was an AI (Claude Sonnet 4.0) that suggest to include the last bit on Academic Integrity and red lines. Hahh.
