Using a dataset of modernist artworks auctioned by Christie’s (2007-2024), the study employs hedonic regression, advanced ML, and Convolutional Neural Networks. Results show ML models outperform traditional methods, revealing biases in auction house estimates. Visual features are relevant predictors of price and improve predictions modestly. Auction house valuation biases when combined with ML modes can be interpreted and subsequently mitigated. These findings highlight the promise of data-driven, scalable art valuation frameworks, advancing both academic research and industry practice.engAlternative financeArt valuationModern artMachine learningForecastingRegressionConvolutional neural networkmaster thesis203961803
