## Question

Compare analogy versus inductive learning.

## Short answer

Analogy transfers knowledge from one similar case to solve a new problem. Inductive learning generalizes from many specific examples to form a general rule. Analogy maps old solution; induction derives general concepts.

## Answer

**Learning by analogy** transfers knowledge from a known, similar situation (source) to solve a new problem (target). **Inductive learning** generalises from many specific examples to a general rule or concept.

| Point | Analogy | Inductive learning |
|---|---|---|
| Idea | Maps old solution to a similar new problem | Generalises from examples to a rule |
| Input | One or few similar past cases | Many training examples |
| Reasoning | Similarity matching, mapping | Generalisation, from specific to general |
| Output | Solution to a particular new problem | General concept or hypothesis |
| Example | Understanding the atom through the solar system | Learning "birds fly" from many bird examples; decision trees (ID3) |
| Risk | Wrong if the similarity is superficial | Over-generalisation, noisy data |

## Check yourself

The answer's key points as multiple-choice questions, with the correct option and why.

1. What does inductive learning do?
   A. Maps one old solution to a new similar problem
   B. Memorises each example
   C. Generalises from many specific examples to a general rule or concept
   D. Learns only from a single case
   Answer: C. Induction goes from specific to general. (Key point: Inductive definition)

2. What does learning by analogy rely on?
   A. Many training examples and generalisation
   B. Random trial and error
   C. Reward signals only
   D. One or few similar past cases mapped by similarity matching
   Answer: D. It transfers a source solution to a target problem. (Key point: Analogy input)

3. What is a risk of analogy learning?
   A. It fails if the similarity is only superficial
   B. Over-generalisation from noisy data
   C. Needing a huge dataset
   D. Producing no solution at all
   Answer: A. Over-generalisation is the induction risk. (Key point: Risk)
