Surrogates and Approximations in Engineering Design

Duration: 09:05:00
Lectures: 19
Level: Beginner

In the context of engineering design, often the functional objective and the design constraints are
approximated by connecting the design variables and the responses of interest at few points on the design space. Since these are approximation of the original functions, they are called surrogates and are widely used in design studies. This course will focus on introducing such surrogates – on how to build, evaluate and use them in design. Surrogates discussed will include polynomial regression, kriging and radial basis function while Desgin of Experiments discussions will include latin hypercube sampling and hammersley sequence.
