# Dataset summary
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.

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](https://huggingface.co/datasets/ai-lab/MBD). MBD-mini has data based on 10% of unique clients listed in MBD.

# Data
The dataset consists of anonymized historical data, which contains the following information for some of the Bank's clients over 12 months:
- transaction activity (transactions) Details about past transactions including amounts, types, and dates;
- dialog embeddings (dialogs) Embeddings from customer interactions, which capture semantic information from dialogues;
- geo-activity (geostream) Location-based data representing clients' geographic activity patterns.

Objective: To predict for each user the taking/not taking of each of the four products within a month after the reporting date, historical data for them is in targets

The dataset is divided into 5 folds based on client_split (which consist of an equal number of unique clients) for cross-validation purposes.
