Dataset Generalizability

The gap

Consensus across the literature

Supporting evidence — 6 representative gaps

• Google Play Store Apps Analysis using NLP (2026) · doi

  The analysis is limited to a single dataset (9,146 apps from Kaggle) without cross-validation on other app store datasets or different domains to assess generalizability.

  Keywords: limited single dataset apps kaggle without cross validation store datasets different domains assess generalizability
• Artificial intelligence for traumatic brain injury imaging: a translational review from algorithm development to clinical implementation (2026) · doi

  Dataset homogeneity introduces systematic bias; publicly available datasets predominantly originate from specialized centers and may underrepresent certain demographic groups, injury types, or imaging protocols, risking inequitable performance when deployed in underserved or diverse populations.

• Multi-Class Sewer Defect Detection with Vision-Language Models (2026) · doi

  Two strategies could be pursued for dataset design: (i) targeted datasets that compensate for low-performing classes, or (ii) robustly sampled datasets that reflect field distributions.

• Ensuring Accuracy and Stability of Multidimensional Data Clustering Using Kohonen Self-Organizing Maps Based on Automatic Data Reduction (2026) · doi

  The method was tested on a single dataset of 1000 observations; validation on diverse datasets with different sizes and characteristics is needed.

  Keywords: tested single dataset observations validation diverse datasets different sizes characteristics needed
• Personalized Recommendation System for E-Commerce Platform (2026) · doi

  Although the system performs efficiently with the available dataset, it needs real-time user data and larger datasets for improved accuracy.
