Defining diagnosis

Data and hypothesis spaces

Mapping data to hypotheses

Two views of diagnosis

Patient:
A: Normal
B: High
C: Low
D: Normal
E: Normal
F: Normal
G: Normal
H: Low
Illnesses:
ο Alphaitis: Elevated A, Reduced C, Elevated F
ο Betatosis: Elevated B, Reduced C, Elevated E, Reduced H
ο Gammanoma: Elevated D, Elevated E, Elevated F
ο Deltacol: Elevated B, Reduced C
ο Epsicusus: Reduced H
ο Zetad: Elevated B, Reduced C, Reduced E, Reduced F
ο Etaemia: Elevated A, Reduced D, Reduced H
ο Thetadesis: Elevated B, Reduced C, Reduced H
ο Iotalgia: Elevated A, Reduced E, Elevated F, Elevated G
ο Kappacide: Reduced A, Reduced F, Reduced G
ο Lambdacrite: Reduced A, Reduced E, Reduced F, Reduced G
ο Mutension: Elevated A, Elevated G
What illness (or set of illnesses) would you use to diagnose this patient?

Diagnosis: To determine what is wrong with a malfunctioning device.

Assignment

How would you use diagnosis to design an agent that could answer Raven’s progressive matrices?

To recap…

Defining diagnosis

Process of diagnosis

Diagnosis as classification

Diagnosis as abduction
