Self-supervised learning methods, including contrastive learning based on Heterogeneous graph neural networks (HGNNs), have achieved great success in learning the representations of heterogeneous information networks (HINs). However, the existing self-supervised methods usually neglect the entanglement of the latent factors behind HINs, which decreases the performance of downstream tasks. In this paper, we propose Multi-level Disentangled Heterogeneous Graph Contrastive learning method and learning disentangled HIN node representations in a self-supervised way. Specifically, we first design a tailored encoder to capture the latent factors and semantics of nodes in input HIN and learn their factorized representations. Then we propose a novel contrastive learning discrimination objective designed for disentangled HIN node representation learning. Extensive experiments conducted on various real-world datasets demonstrate the superiority of our method against state-of-the-art baselines.

Acquiring the 3D structure of plants is a critical task in the agricultural industry. Existing methods of generating 3D point clouds for multiple plants require a long processing time. In this paper, a 3D reconstruction method for numerous plants is proposed. Firstly, camera parameters in different viewpoints are obtained from the aerial image of plants by incremental structure from motion. Subsequently, the learning-based multi-view stereo takes images and the corresponding camera parameters as inputs to acquire initial depth maps. Finally, the depth maps are filtered and fused to produce a complete and dense 3D point cloud. We conducted experiments on an agricultural orchard dataset to compare with other methods. Experimental results demonstrate that our method reconstructs point clouds of plants with good quality while having a lower running time.

Handling imbalanced datasets remains a critical challenge in financial machine-learning applications such as loan approval, credit scoring, and fraud detection. We present Imbalanced Financial Diffusion (Imb-FinDiff), a novel denoising diffusion framework designed to address class imbalance in financial tabular data. Our framework leverages embedding encodings for categorical and numerical attributes, effectively managing the complexities of mixed-type financial datasets. By incorporating a dual learning objective, (i) diffusion timestep noise and (ii) class label prediction, we synthesize minority class samples. Extensive experiments on diverse and real-world financial datasets demonstrate that Imb-FinDiff maintains the statistical properties of the original data while reducing bias caused by class imbalance. The minority class samples generated by Imb-FinDiff enhance the utility and fidelity of downstream machinelearning classifiers.
