How to use the dataset

This dataset can be used to analyze the key factors that influence customer attrition. Analysts can use this dataset to understand customer demographics, spending patterns, and relationship with the credit card provider to better predict customer attrition.

Research Ideas

• Using the customer demographics, such as gender, marital status, education level and income category to determine which customer demographic is more likely to churn.
• Analyzing the customer’s spending behavior leading up to churning and using this data to better predict the likelihood of a customer of churning in the future.
• Creating a classifier that can predict potential customers who are more susceptible to attrition based on their credit score, credit limit, utilization ratio and other spending behavior metrics over time; this could be used as an early warning system for predicting potential attrition before it happens

Abstract

The BreastDCEDL_ISPY2 dataset is a curated, deep learning–ready resource that integrates pretreatment 3D Dynamic Contrast-Enhanced MRI (DCE-MRI) scans from 982 breast cancer patients enrolled in the I-SPY2 TRIAL, sourced from The Cancer Imaging Archive (TCIA). Imaging data has been standardized from raw DICOM to 3D NIfTI volumes, preserving signal integrity and spatial resolution. The dataset includes extensive non-imaging supporting data, such as tumor annotations, DICOM metadata, and demographics. To facilitate reproducible research, fixed benchmark train/validation/test splits are provided, stratified by biomarker subtypes and response outcomes. This dataset enables diverse research applications, including the development of deep learning models for predicting treatment response, radiomics-based analyses, and hormone receptor (HR) and HER2 status classification. It also facilitates benchmarking of advanced architectures such as Vision Transformers, and supports clinical translation efforts in the field of precision oncology

Introduction

Breast cancer remains one of the most prevalent causes of cancer-related mortality worldwide, and early detection coupled with accurate treatment response monitoring is essential for improving outcomes. Dynamic Contrast-Enhanced MRI (DCE-MRI) is a cornerstone modality for breast cancer imaging, offering unique insights into tumor vascularity, morphology, and treatment response. Despite its clinical importance, progress in computational and deep learning–based analysis of DCE-MRI has been hindered by the lack of large, standardized, and publicly available datasets. The BreastDCEDL_ISPY2 dataset was created to address this gap by consolidating and harmonizing imaging and clinical data from the I-SPY2 TRIAL. With 982 patients across more than 22 institutions, it represents one of the largest publicly accessible collections of pre-treatment DCE-MRI scans for breast cancer. Importantly, the dataset includes standardized 3D NIfTI volumes, tumor annotations, voxel-based tumor volumes, and harmonized clinicopathologic metadata such as hormone receptor status, HER2 status, and pathologic complete response outcomes. What makes BreastDCEDL_ISPY2 unique is its deep learning–ready structure and benchmark design. By providing consistent preprocessing, unified annotations, and predefined training/validation/test splits, the dataset enables reproducible research and direct comparison of computational methods. It lowers the technical barriers to working with heterogeneous MRI data, facilitates the development and validation of advanced machine learning models—including transformer-based architectures—and supports clinically relevant investigations into treatment response prediction and personalized therapy planning. The dataset includes extensive non-imaging supporting data:

• Tumor annotations include both segmentation masks and region-of-interest (ROI) delineations.
• Accompanying DICOM metadata encompasses voxel dimensions, signal enhancement ratio (SER) time points, and contrast agent injection timestamps.
• Clinical metadata provides comprehensive patient information, including demographic variables (age, race, menopausal status), hormone receptor (HR) and HER2 receptor status, as well as treatment outcomes, specifically pathologic complete response (pCR).

Methods

Subject Inclusion and Exclusion Criteria

The BreastDCEDL_ISPY2 dataset integrates patient data from the I-SPY2 TRIAL (2010–2016), yielding 985 patients with pretreatment DCE-MRI scans. Inclusion required at least three acquisitions (pre-contrast, early post-contrast, late post-contrast). Patients with incomplete imaging or missing essential metadata were excluded (3 cases), leaving 982 patients. The cohort reflects a clinically diverse population, with a mean age of ~50 years, racial composition (majority White, ~17% Black, others underrepresented), and tumor subtypes spanning HR+/HER2−, HER2+, and triple-negative cancers. pCR status is available for the majority of patients. Treatment histories reflect standardized neoadjuvant chemotherapy protocols. While the dataset includes multicenter acquisitions (22+ institutions), potential biases include predominance of U.S.-based populations, underrepresentation of some ethnic groups, and the trial setting, which may differ from community practice.

Data Acquisition

• MRI Acquisition: Pretreatment 3D DCE-MRI acquired on 1.5T and 3T scanners. Protocols varied across institutions but consistently included pre-contrast, early post-contrast, and late post-contrast acquisitions after gadolinium administration. Key technical parameters (TR, TE, slice thickness, voxel size, FOV) are preserved in metadata.
• Clinical Data: Captured through electronic trial databases. Variables include demographics (age, race, menopausal status), receptor status (HR, HER2), tumor volume, and treatment outcome (pCR).
• Other Data: Signal Enhancement Ratio (SER) maps and voxel-based tumor volumes are provided.
• Missing Data: 3 patients were excluded due to incomplete imaging or metadata.

Data Analysis

• File Format Conversions: Raw DICOM images were converted into standardized 3D NIfTI volumes using a custom pipeline. Conversion preserved 16-bit dynamic range by storing as 64-bit floating-point data.
• Manual Annotation and Segmentation Protocols: Tumor segmentations and ROI delineations provided by I-SPY2 radiologists; converted to binary 3D masks aligned to imaging volumes. Only the primary tumor was annotated if multiple tumors were present.
• Quality Control and Validation: Tumor annotations were reviewed for alignment with MRI volumes. Consistency checks ensured tumor masks aligned across temporal phases. Patients with fewer than three valid acquisitions were excluded.
• Scripts, Code, and Software Versions: Pipelines and Vision Transformer implementation are available on GitHub:https://github.com/naomifridman/BreastDCEDL" rel="nofollow"> https://github.com/naomifridman/BreastDCEDL

Usage Notes

Data Organization and Naming Conventions All imaging data are provided in standardized 3D NIfTI format, converted from original DICOM files while preserving full signal integrity. File names follow the structure:

• Training set: 784 patients (32.1% pCR rate).
• Validation set: 99 patients (32.3% pCR rate).
• Test set: 99 patients (32.3% pCR rate).

Partitioning was stratified by biomarker status (HR, HER2) and pCR outcomes to ensure balanced distributions across subsets. Users are encouraged to adopt these predefined splits when developing predictive models to enable fair comparisons across studies. Clinical Data Files Clinical and pathologic metadata are distributed in standardized TSV format. Variables include demographics (age, race, menopausal status), biomarker status (HR, HER2), tumor volume, and pCR outcomes. TSV files can be opened with standard spreadsheet software (e.g., Microsoft Excel, LibreOffice Calc) or programmatically accessed using Python (pandas) or R. Software Recommendations

• NIfTI images: Compatible with common medical imaging platforms such as 3D Slicer, ITK-SNAP, and FSL. Python users may rely on nibabel for loading and handling imaging volumes.
• Segmentation masks: Provided as binary 3D NIfTI volumes (1 = tumor, 0 = background), directly loadable in the same software.

Potential Sources of Error or Variability

• Inter-cohort heterogeneity: Imaging protocols (field strength, TR/TE, slice thickness) varied across centers, potentially introducing site effects.
• Only the largest lesion was annotated for multifocal disease.
• Population bias (predominantly U.S., underrepresentation of minorities).

This data collection consists of multiparametric MRI scans of 40 adult patients with histopathologically confirmed WHO grade 4 astrocytoma, who underwent surgery at the Río Hortega University Hospital in Valladolid, Spain, between January 2018 and December 2022. The dataset encompasses 600 MRI series, covering three time points: preoperative, early post-operative (less than 72 hours after surgery), and the follow-up scan, at which recurrence is diagnosed. Patients included in the sample underwent gross total resection (GTR) or near total resection (NTR), defined as having no residual tumor enhancement and an extent of resection of more than 95% of the initial enhancing volume, respectively. The modified Response Assessment in Neuro-Oncology criteria (RANO) were used to define tumor progression.

The dataset contains T1-weighted (T1w), T2-weighted (T2w), Fluid Attenuated Inversion Recovery (FLAIR), T1w contrast-enhanced (T1ce) sequences, and diffusion-weighted imaging-derived apparent diffusion coefficient (ADC) maps. It also includes clinical and demographic data, IDH status, treatment information, and volumetric assessment of the extent of the resection. Moreover, the dataset comprises expert-validated segmentations of tumor subregions (e.g., enhancing tumor, necrosis, peritumoral region), generated through computer-aided methods from preoperative, postoperative, and follow-up scans.

This dataset is unique in its inclusion of patients who underwent extensive resection of > 95% of the enhancing tumor. It also stands out from other publicly available datasets by providing early postoperative studies and segmentations, filling the gap in preoperative-focused datasets. By making these data publicly available, the scientific community can analyze recurrence patterns in patients who underwent total or near-total resection and develop new registration and segmentation algorithms focused on post-surgical and follow-up studies.

Food festivals have been a growing tourism sector in recent years due to their contributions to a region’s economic, marketing, brand, and social growth. This study analyses the demand for the Bahrain food festival. The stated objectives were: i) To identify the motivational dimensions of the demand for the food festival, (ii) To determine the segments of the demand for the food festival, and (iii) To establish the relationship between the demand segments and socio-demographic aspects. The food festival investigated was the Bahrain Food Festival held in Bahrain, located on the east coast of the Persian Gulf. The sample consisted of 380 valid questionnaires and was taken using social networks from those attending the event. The statistical techniques used were factorial analysis and the K-means grouping method. The results show five motivational dimensions: Local food, Art, Entertainment, Socialization, and Escape and novelty. In addition, two segments were found; the first, Entertainment and novelties, is related to attendees who seek to enjoy the festive atmosphere and discover new restaurants. The second is Multiple motives, formed by attendees with several motivations simultaneously. This segment has the highest income and expenses, making it the most important group for developing plans and strategies. The results will contribute to the academic literature and the organizers of food festivals.

BackgroundSegmentation of heterogeneous patient populations into parsimonious and relatively homogenous groups with similar healthcare needs can facilitate healthcare resource planning and development of effective integrated healthcare interventions for each segment. We aimed to apply a data-driven, healthcare utilization-based clustering analysis to segment a regional health system patient population and validate its discriminative ability on 4-year longitudinal healthcare utilization and mortality data.MethodsWe extracted data from the Singapore Health Services Electronic Health Intelligence System, an electronic medical record database that included healthcare utilization (inpatient admissions, specialist outpatient clinic visits, emergency department visits, and primary care clinic visits), mortality, diseases, and demographics for all adult Singapore residents who resided in and had a healthcare encounter with our regional health system in 2012. Hierarchical clustering analysis (Ward’s linkage) and K-means cluster analysis using age and healthcare utilization data in 2012 were applied to segment the selected population. These segments were compared using their demographics (other than age) and morbidities in 2012, and longitudinal healthcare utilization and mortality from 2013–2016.ResultsAmong 146,999 subjects, five distinct patient segments “Young, healthy”; “Middle age, healthy”; “Stable, chronic disease”; “Complicated chronic disease” and “Frequent admitters” were identified. Healthcare utilization patterns in 2012, morbidity patterns and demographics differed significantly across all segments. The “Frequent admitters” segment had the smallest number of patients (1.79% of the population) but consumed 69% of inpatient admissions, 77% of specialist outpatient visits, 54% of emergency department visits, and 23% of primary care clinic visits in 2012. 11.5% and 31.2% of this segment has end stage renal failure and malignancy respectively. The validity of cluster-analysis derived segments is supported by discriminative ability for longitudinal healthcare utilization and mortality from 2013–2016. Incident rate ratios for healthcare utilization and Cox hazards ratio for mortality increased as patient segments increased in complexity. Patients in the “Frequent admitters” segment accounted for a disproportionate healthcare utilization and 8.16 times higher mortality rate.ConclusionOur data-driven clustering analysis on a general patient population in Singapore identified five patient segments with distinct longitudinal healthcare utilization patterns and mortality risk to provide an evidence-based segmentation of a regional health system’s healthcare needs.

This dataset comprises a meticulously structured collection of customer-related information designed for efficient machine learning applications. It consists of three primary folders—offers, customers, and events—each containing valuable data that enable detailed analysis of customer behavior, response to promotional offers, and overall engagement over a 30-day period.

Offers The offers folder contains comprehensive details on various promotional offers that were sent to customers within the 30-day timeframe. Each offer is uniquely identified by an offer_id, which serves as the primary key. Offers are categorized into three distinct types:

BOGO (Buy One, Get One): A customer must purchase a specific product to receive another for free. Discount: A direct discount applied to purchases, incentivizing spending. Informational: Provides details about a promotion without requiring any spending or offering a direct reward. Each offer has specific requirements and rewards:

difficulty: The minimum amount a customer must spend to qualify for the offer. reward: The monetary reward (in USD) received upon successful completion of the offer. duration: The number of days a customer has to complete the offer after receiving it. channels: The marketing channels used to send the offer, which may include email, mobile app notifications, social media, or direct mail. By analyzing the offers dataset, businesses can assess the effectiveness of different promotional strategies and optimize future campaigns.

Customers The customers folder contains demographic information for each member in the dataset. Each customer is uniquely identified using customer_id, which acts as the primary key. The dataset includes the following attributes:

became_member_on: The date (formatted as YYYYMMDD) when the customer created their account. This information helps track customer loyalty and tenure. gender: The customer's gender, categorized as (M)ale, (F)emale, or (O)ther. This allows for demographic segmentation and targeted marketing analysis. age: The customer’s age, useful for analyzing purchasing patterns and offer preferences across different age groups. income: The estimated annual income of the customer (in USD), enabling insights into spending behavior based on economic status. With this dataset, machine learning models can predict customer preferences, segment users into meaningful groups, and tailor offers based on demographic factors.

Events The events folder logs customer activity throughout the 30-day period, capturing interactions with offers and transactions. Each record is associated with a specific customer_id, serving as a foreign key to link activities to individual users. The dataset includes:

event: A categorical description of the customer's interaction. The possible events include:

Transaction: A recorded purchase made by the customer. Offer Received: A notification that an offer was sent to the customer. Offer Viewed: The customer actively opened and engaged with the offer. Offer Completed: The customer fulfilled the necessary conditions to claim the offer's reward. value: A dictionary of values linked to the event, which varies depending on the type of activity:

For transactions, value represents the amount spent by the customer. For offers received, viewed, or completed, value contains the corresponding offer_id. time: A numerical indicator representing the number of hours passed in the 30-day observation window (starting from 0). This allows for tracking customer engagement over time and understanding behavioral trends.

By analyzing the events dataset, businesses can gain insights into customer interactions, measure the success of promotional offers, and identify patterns in spending behavior. Machine learning models can leverage this data to predict which offers will be most effective for different customer segments.
