# FreshRetailNet-LT
## Dataset Overview
FreshRetailNet-LT is the first large-scale benchmark for censored demand estimation in the fresh retail domain, **incorporating approximately 20% organically occurring stockout data**. It comprises more than 20K store-product time series of detailed hourly sales data from 1057 stores in 18 major cities, encompassing 576 perishable SKUs with meticulous stockout event annotations. The hourly stock status records unique to this dataset, combined with rich contextual covariates including promotional discounts, precipitation, and other temporal features, enable innovative research beyond existing solutions.

- [Github Repo](It will be posted later.) - Access the complete pipeline used to train and evaluate.
This dataset is ready for commercial/non-commercial use.
