 This dataset is designed to assist in predicting a customer's propensity to purchase various products within a month following the reporting date. The dataset includes anonymized historical data on transaction activity, dialog embeddings, and geo-activity for some bank clients over 12 months.
 
 Reduced dataset version is avaliable as [MBD-mini](https://huggingface.co/datasets/ai-lab/MBD-mini). The mini MBD dataset contains a reduced subset of the data, making it easier and faster to work with during the development and testing phases. It includes a smaller number of clients and a shorter time span but maintains the same structure and features as the full dataset. MBD-mini has data based on 10% of unique clients listed in MBD.
+To get a balanced version of the dataset, you can use the field is_balanced == 1
