More and more people prefer to buy a second-hand car rather than a new one due to the increasing cost of new cars and their fast devaluation in price. Consequently, there has also been an increase in online marketplaces for peerto- peer (P2P) second-hand cars trades. A robust price estimation is needed for both dealers, to have a good idea on how to price their cars, and buyers, to understand whether a listing is overpriced or not. Price estimation for second-hand cars has been, to my knowledge, so far only explored with numerical and categorical features such as mileage driven, brand or production year. An approach that also uses image data has yet to be developed. This work aims to investigate the use of a multi-input price estimation model for second-hand cars taking advantage of a convolutional neural network (CNN), to extract features from car images, combined with an artificial neural network (ANN), dealing with the categorical-numerical features, and assess whether this method improves accuracy in price estimation over more traditional single-input methods. To train and evaluate the model, a dataset of second-hand car images and textual features is scraped from a marketplace and curated such that more than 700 images can be used for the training.Castelli, MauroRUNFiorani, Matteo2022-03-11T14:01:52Z2022-01-272022-01-27T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfhttp://hdl.handle.net/10362/134276TID:202961125enginfo:eu-repo/semantics/openAccessreponame:Repositórios Científicos de Acesso Aberto de Portugal (RCAAP)instname:FCCN, serviços digitais da FCT – Fundação para a Ciência e a Tecnologiainstacron:RCAAP2024-05-22T18:00:05Zoai:run.unl.pt:10362/134276Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireinfo@rcaap.ptopendoar:https://opendoar.ac.uk/repository/71602025-05-28T17:30:59.361041Repositórios Científicos de Acesso Aberto de Portugal (RCAAP) - FCCN, serviços digitais da FCT – Fundação para a Ciência e a Tecnologiafalse
