Research Questions Could training on multiple tasks and transfer learning perform better than training on one task independently using the Amazon Product Catalog Dataset? What architecture choices and hyperparameters shall we use in both multi-task and transfer learning to obtain better performance? Can multi-task learning and transfer learning be useful in the ecommerce domain to enhance user-experience? Kickoff Master Thesis – Aamna Najmi © sebis
