Pricing a rental property on Airbnb is a challenging task for the owner as it determines the number of customers for the place. On the other hand, customers have to evaluate an offered price with minimal knowledge of an optimal value for the property. This paper aims to develop a reliable price prediction model using m…
Training machine learning (ML) models is expensive in terms of computational power, amounts of labeled data and human expertise.
