Computational models Flashcards
1
Q
What are the three computational phases?
A
From a theory, evaluating and finding discrepancies
2
Q
what is descriptive adequacy?
A
Accuracy of a model in predicting a data set, both at the qualitative level and at the quantitative level (goodness of fit).
3
Q
How do you assess descriptive adequacy
A
factorial method and regression
4
Q
Goals in developing a computational model
A
completeness and sufficiency
5
Q
How to adjudicate between competing theories?
A
- PHASE 1: compare the descriptive adequacy of the different models
- PHASE 2: two models are very similar with respect to descriptive adequacy (all effects simulated by model A are also simulated by model B, and vice versa). If the data do not discriminate between models, how can we choose?
- A. Simplicity criterion:choose the simpler model
- B. Falsificationism (strong inference testing)
