Article Synopsis
  • - The study addresses the challenges in gene expression data analysis, particularly high dimensionality, limited sample sizes, and feature redundancy, by proposing a new algorithm called Clustering-Guided Unsupervised Feature Selection (CGUFS).
  • - CGUFS offers three key improvements: an adaptive strategy for assigning cluster pseudo-labels, a feature grouping method to handle redundancy, and an adaptive filtering strategy to retain the most relevant features.
  • - Experimental results demonstrate that CGUFS outperforms existing algorithms, achieving higher accuracy rates (74.37% for C4.5 and significantly improved results for the Adaboost classifier) in selecting optimal features.

Deep ensemble learning, where we combine knowledge learned from multiple individual neural networks, has been widely adopted to improve the performance of neural networks in deep learning. This field can be encompassed by committee learning, which includes the construction of neural network cascades. This study focuses on the high-dimensional low-sample-size (HDLS) domain and introduces multiple instance ensemble (MIE) as a novel stacking method for ensembles and cascades.

Artificial Intelligence (AI) technologies have been powerful solutions used to improve food yield, quality, and nutrition, increase safety and traceability while decreasing resource consumption, and eliminate food waste. Compared with several qualitative reviews on AI in food safety, we conducted an in-depth quantitative and systematic review based on the Core Collection database of WoS (Web of Science). To discover the historical trajectory and identify future trends, we analysed the literature concerning AI technologies in food safety from 2012 to 2022 by CiteSpace.

Deep learning has become a primary choice in medical image analysis due to its powerful representation capability. However, most existing deep learning models designed for medical image classification can only perform well on a specific disease. The performance drops dramatically when it comes to other diseases.
