Mathematical Modeling
- What is the mathematical model?
- Real world → observation → modeling → prediction
- Observe the real world?→ modeling?→ predict the real world
- Types of mathematical modeling
- Empirical modeling: modeling based on data alone.
- Theoretical modeling: modeling based more on theory than on data alone.
The Method of Least Squares
- Types of models
- Linear models
- Nonlinear models
- Linear models
- y = w_0 x_0+w_1 x_1+...+w_n x_n
- Nonlinear models
- Convert?the nonlinear models into
f(y) = w'_0 g(x_0)+w'_1 g(x_1)+...+w'_n g(x_n) - For example,
y=ae^x
\Rightarrow ln(y)=ln(a) + x - Then, approach the converted equation as a linear model.
