Predicting categorical sales in different stores accurately brings advantages in terms of operational efficiency and tracking the performances of stores or operational processes. Currently, the analytics team is building models based on product categories and stores, resulting in a huge number of models. Our objective is to decrease the computational requirements as well as increasing the performance of the predictions.
DataThe challenge has the following sample datasets available for download
Currently the sales are predicted with 5-7% accuracy (in total and in terms of mean absolute percentage error) by using models for each store and product category. Our objective is to increase the overall accuracy as well as the accuracy of store-category-based individual forecasts.
We also welcome any approaches that can allow us to reduce the number of models to be trained by keeping the accuracy roughly the same. We aim to reduce the number of models by 50%.
- Exceeding 5% accuracy.
- Increasing the accuracy of store-category-based predictions by 10%.
- Decreasing the number of models by 50%.
