We participate in the kaggle competition 'Grupo Bimbo Inventory Demand' (https://www.kaggle.com/competitions/grupo-bimbo-inventory-demand/data), which ended 9 years ago (better late than never). Given sales data from many vendors containing the products and amounts sold, the objective is to predict the future demand for each product sold by each vendor. A noteworthy aspect of this competition is the size of the training dataset, which has roughly 75 million entries.
