How do you handle uncertainties and limitations in theoretical models?

Sample interview questions: How do you handle uncertainties and limitations in theoretical models?

Sample answer:

1. Embrace Uncertainty: Recognize that uncertainty is an inherent part of theoretical modeling and accept it rather than trying to eliminate it completely.

2. Rigorous Assumptions and Approximations: Clearly outline the assumptions and approximations used in the model. This enables you to identify potential sources of uncertainty and limit their impact on the model’s predictions.

3. Sensitivity Analysis: Conduct sensitivity analysis to assess how variations in input parameters or assumptions affect the model’s outcomes. This helps understand the robustness of the model and the sensitivity of its predictions to changes in specific parameters.

4. Uncertainty Quantification: Employ mathematical techniques such as Bayesian inference, fuzzy logic, or statistical methods to quantify uncertainties in the model. This provides a framework for incorporating experimental data and observations to refine the model and reduce uncertainties.

5. Error Analysis: Evaluate the accuracy and precision of the model by comparing its predictions with experimental data or other reliable sources of information. Identify systematic and random errors and work towards minimizing their impac… Read full answer
