Paper 4 MultiObjective

Question 1

Pareto optimality

Answer 1

Not pareto dominated by anything

Question 2

Pareto dominating

Answer 2

Better at at least something and not worst at the rest

Question 3

Naive approaches for MOHPO

Answer 3

Scalarization, transform into single objective (e.g. weighted sum)
Random/grid search

Question 4

Evolutionary approach

Answer 4

Selection using Pareto dominance

Question 5

MO-BO

Answer 5

Multi objective bayesian optimization
Use scalarization or use multiple surrogates

Question 6

ParEGO

Answer 6

Scalarization based MO-BO
First needs weights for all objectives

Question 7

EHI

Answer 7

Surrogate model per objective
