Question 1 · 1 mark · Difficulty 1/3

Which term describes the world changing after training, so that learned patterns stop matching reality?

  1. Overfitting
  2. Generalisation
  3. Inference
  4. Concept drift
Show answer & explanation
✓ Answer: D — Concept drift
Award 1 mark. Performance decays although nothing inside the model has changed, which is why deployed systems are monitored and retrained rather than treated as finished.
Question 2 · 1 mark · Difficulty 1/3

What is the goal that machine learning is actually aiming at?

  1. Performing well on data the model was never trained on
  2. Using as much training data as possible
  3. Reaching a perfect score on the training examples
  4. Running as quickly as possible on ordinary hardware
Show answer & explanation
✓ Answer: A — Performing well on data the model was never trained on
Award 1 mark. This is called generalisation, and it is the only kind of performance that matters once a system is in use.

Kramizo AI Literacy: How machine learning learns from data FAQ

Is Kramizo free for Kramizo students preparing for AI Literacy?
Yes — completely free. Every student gets 45 questions a day on the free plan, with no card required and no trial countdown. That free quota works across every subject and every topic in our bank, so you can mix How machine learning learns from data practice with other AI Literacy topics or even switch to a totally different Kramizo subject without paying anything. Kramizo's optional Pro plan removes the daily cap and adds detailed progress analytics, but the free tier is the real product — used by thousands of GCSE, IGCSE and CSEC students.
Are the How machine learning learns from data questions aligned to the official Kramizo AI Literacy syllabus?
Every question is written against the published Kramizo AI Literacy specification, including the exact command words (state, describe, explain, calculate, evaluate, etc.), mark allocations, and difficulty tier you'd see on a real Kramizo paper. Explanations are written in the style of official examiner mark schemes — they tell you what is being awarded marks and why distractors are wrong, not just whether you got it right. The bank is continually refined to match the latest syllabus updates from Kramizo.
How is How machine learning learns from data typically tested on Kramizo AI Literacy papers?
How machine learning learns from data appears across multiple question types on real Kramizo AI Literacy papers — most commonly as multiple-choice questions in the objective section, structured short-answer questions in the main paper, and occasionally as part of an extended response.
