What session 1 is for

The mathematics

  • Separate a scenario from a forecast, and say why only one carries a probability
  • State the prediction / inference split and say which one a question needs
  • Recognise where, in a published study, the evidence stops and the construction begins

The Python

  • {‘Run a local analytical workstation’: ‘VS Codium, a virtual environment, a locally hosted model’}
  • Load the course data with one line, qmib.load(...), and know where the file actually is
  • Read a traceback as information rather than as failure

The international business

  • Say what a number about the past is entitled to claim about the future
  • Name the decision your project’s estimate is supposed to inform
  • Judge whether a strategic question wants an effect or a forecast

Your Python so far

Everything you need to type is on one sheet — how to start Python in VS Codium on your platform, how to make a file and run it, and the four DataFrame moves you will use every week from now on.

A conversation

Europe 2031, and what AI actually is

This is a conversation with an evidence standard

Europe 2031 is useful precisely because it mixes four different kinds of statement — and moves between them without announcing it.

Evidence A claim tied to a source and an observed time period
Scenario A coherent imagined future — not a forecast by default
Prediction A dated, testable statement about an outcome
AI A computational system producing outputs from inputs and learned parameters

Telling these apart, in a text that does not label them, is the skill. It is also the whole of the final paper.

The ninety minutes

00–10 Opening One sentence each: the claim that stayed with you
10–25 Evidence Locate sources, dates, and the boundary of what is observed
25–45 Scenario Identify assumptions; make one claim measurable
45–50 Pause
50–70 AI Use the local model to question one passage — then verify what it says
70–85 Conversation Compare groups; name absent evidence and alternative futures
85–90 Close One claim, one uncertainty, one question

Mark the seams

The scenario has three parts, and they do different work:

  • an observed prologue
  • a speculative 2031
  • a reflective epilogue
Observed Which statements have dated sources?
Constructed Where do assumptions begin doing the work?
Rhetorical Which framing makes one future feel inevitable?

The seam between the first two is rarely marked in the text. Find it.

Four stops, before you debate

Source stop. What is the source, the date, the unit, and the observed period?

Measurement stop. What variable would make this claim testable?

Alternative stop. What mechanism, or what future, is missing?

Reversal stop. What evidence would change your mind? If nothing would, you are not holding a claim — you are holding a position.

What a language model actually does

\[\text{prompt tokens} \;\rightarrow\; \text{learned parameters} \;\rightarrow\; \text{next-token scores} \;\rightarrow\; \text{generated text}\]

What it can do. Propose questions, transformations, code, summaries, alternative phrasing.

What it cannot guarantee. Truth. Valid sources. Causal identification. Reproducibility. Responsibility.

Everything in this course that looks like a rule about AI use follows from that second list.

Try it, and check it

Take one passage from Europe 2031. Ask your local model to state the strongest objection to it. Then verify the objection — is the source real, is the number right, does the mechanism hold?

Whatever you find is the first entry in the habit this course grades: an LLM output you identified as wrong, unverifiable, or misleading, and how you established that.

Closing round

Ninety seconds per group. Everyone speaks.

One claim The narrowest claim the evidence supports
One uncertainty The assumption, or the missing evidence
One question Carry it into Session 02

Listen for traceable evidence, not confidence of delivery.

Before Session 02

Read the-supervised-learning-problem.md if you would like a head start — optional, and not examinable. Session 02 introduces everything it needs.
