We study the forces behind Google’s large web-search market share. We develop a demand model with switching costs, quality beliefs, and inattention, and estimate it using a field experiment. We find ...

Abstract: Many existing surrogate-assisted optimization algorithms are limited to designing antennas with continuous variables only. However, numerous challenges emerge when tackling antenna ...

Abstract: Feature selection is one of the major challenges in machine learning problems. It reduces the number of features and improves performance by removing the irrelevant and unnecessary ones.
