Special Issue Information

Dear Colleagues,

Machine learning (ML) has transformed various industries, including healthcare, finance, cybersecurity, and autonomous systems. However, despite its success, ML still faces critical data-related challenges that impact its reliability, scalability, and fairness. This Special Issue, “Data-Related Challenges in Machine Learning: Theory and Application”, aims to explore fundamental issues, theoretical advancements, and innovative solutions addressing data quality, bias, privacy, efficiency, and interpretability in ML. 

The special issue will focus on, but not be limited to, the following key challenges: 

- Data Quality and Preprocessing: Handling noisy, missing, and inconsistent data remains a fundamental issue. Research on automated data cleaning, robust feature engineering, and data augmentation techniques is essential for improving ML model performance. 

- Bias and Fairness in ML: Many ML systems inherit biases from their training data, leading to unfair outcomes. Ensuring fairness through bias detection, fairness-aware learning, and ethical AI development is crucial. 

- Data Scarcity and Efficiency: In many real-world applications, collecting large, high-quality datasets is impractical. Methods such as few-shot learning, transfer learning, and self-supervised learning provide potential solutions. 

- Privacy and Security in ML: As ML models handle sensitive information, privacy-preserving techniques like federated learning, differential privacy, and encrypted machine learning are gaining attention. 

- Data Interpretability and Robustness: Understanding how ML models make decisions is essential for trust and adoption. Explainable AI (XAI) and adversarial robustness research contribute to making ML systems more transparent and reliable.

Maize is a vital global crop, serving as a fundamental component of global food security. To support sustainable maize production, the accurate classification of maize seeds—particularly distinguishing haploid from diploid types—is essential for enhancing breeding efficiency. Conventional methods relying on manual inspection or simple machine learning are prone to errors and unsuitable for large-scale data. To overcome these limitations, we propose Slot-Maize, a novel deep learning architecture that integrates Convolutional Neural Networks (CNN), Slot Attention, Gated Recurrent Units (GRU), and Long Short-Term Memory (LSTM) layers. The Slot-Maize model was evaluated using two datasets: the Maize Seed Dataset and the Maize Variety Dataset. The Slot Attention module improves feature representation by focusing on object-centric regions within seed images. The GRU captures short-term sequential patterns in extracted features, while the LSTM models long-range dependencies, enhancing temporal understanding. Furthermore, Grad-CAM was utilized as an explainable AI technique to enhance the interpretability of the model’s decisions. The model demonstrated an accuracy of 96.97% on the Maize Seed Dataset and 92.30% on the Maize Variety Dataset, outperforming existing methods in both cases. These results demonstrate the model’s robustness, generalizability, and potential to accelerate automated maize breeding workflows. In conclusion, the Slot-Maize model provides a robust and interpretable solution for automated maize seed classification, representing a significant advancement in agricultural technology. By combining accuracy with explainability, Slot-Maize provides a reliable tool for precision agriculture. Full article
