Harith Al-Sahaf,Ying Bi,Qi Chen,Andrew Lensen,Yi Mei,Yanan Sun,Binh Q. Tran,Bing Xue,Mengjie Zhang +8 more
TL;DR: This paper provides a review on evolutionary machine learning techniques for major machine learning tasks such as classification, regression and clustering, and emerging topics including combinatorial optimisation, computer vision, deep learning, transfer learning, and ensemble learning.
Journal ArticleDOI
Cross-Domain Reuse of Extracted Knowledge in Genetic Programming for Image Classification
TL;DR: A novel approach based on transfer learning and GP to solve complex image classification problems by extracting and reusing blocks of knowledge/information automatically discovered from similar as well as different image classification tasks during the evolutionary process achieves better classification performance than the state-of-the-art image classification algorithm.
Journal ArticleDOI
Automatically Evolving Rotation-Invariant Texture Image Descriptors by Genetic Programming
TL;DR: A novel genetic programming-based method that automatically synthesises a descriptor using only two training instances per class is proposed that is robust to rotation and has significantly outperformed, or achieved a comparable performance to, the baseline methods.
Journal ArticleDOI
Two-Tier genetic programming: towards raw pixel-based image classification
TL;DR: This method is compared with feature based image classification by GP and another GP method which also aims to automatically extract image features, and the results show that the highest accuracies are achieved by Two-Tier GP.
Journal ArticleDOI
Keypoints Detection and Feature Extraction: A Dynamic Genetic Programming Approach for Evolving Rotation-Invariant Texture Image Descriptors
TL;DR: Genetic programming is utilized to automatically construct a rotation-invariant image descriptor by synthesizing a set of formulas using simple arithmetic operators and first-order statistics, and determining the length of the feature vector simultaneously using only two instances per class.
