Researchers have adapted a deep neural network, specifically a convolutional neural network (CNN), for the morphological classification of galaxies using crowd-sourced annotations from the Galaxy Zoo 1 dataset. The study explored various training strategies, including fine-tuning the entire network versus just the final layer, incorporating hierarchical classification, and utilizing transfer learning through curriculum learning. Results indicated that training all network layers significantly improved accuracy by 10%, and transfer learning was particularly effective for limited data. The findings suggest that while training with crowd annotations presents unique challenges compared to hard annotations, high accuracy can be achieved with careful methodology. AI
