Knowledge representation learning is commonly used to embed high-dimensional, sparse drug knowledge graphs into low-dimensional, dense vector spaces. Existing methods primarily rely on node features of drug knowledge graphs, which often neglect inherent biases introduced by network characteristics, such as noise, long-tail distribution, data sparsity, and complex relations (1-N, N-1, N-N). This oversight leads to incomplete semantic representation of knowledge graphs during the embedding process, thereby resulting in suboptimal DTI prediction performance. To address these challenges, we propose a novel model termed DAH-DTI, which comprises four components: knowledge graph denoising, high-quality negative sample generation, hyperellipsoid knowledge graph embedding based on Mahalanobis distance, and DTI link prediction. Specifically, the knowledge graph is first denoised to filter out noisy triples and obtain a high-quality gold dataset. Subsequently, adversarial negative sampling is incorporated during pre-training to moderately expand the number of triples. Next, the tail entities of the triples are embedded into a predefined hyperellipsoid for model training. Finally, the trained model is applied to all potential unknown drug-target pairs through link prediction to predict potential DTIs. Experimental results demonstrate that by effectively addressing challenges including data noise, long-tail distribution, data sparsity, and complex relations. The DAH-DTI achieves significant improvements in ACCU, REC, MRR, and Hit@10 on a multi-level phenotype-drug-molecular knowledge graph.

To overcome these limitations, we propose a novel Multi-view Graph Learning Framework with Spectral Encoding and Sparse Cross-Attention (MVGSCA) for predicting miRNA-drug associations. The model constructs node features based on miRNA sequence similarity and drug SMILES similarity. Then it builds two distinct graphs: a gene-mediated functional graph from miRNA-drug target interactions and an association-guided structural graph from known miRNA-drug associations. These two graphs are linearly combined to produce a collaborative feature representation. To capture both local and global topological features, the model applies local power filtering and global heat kernel diffusion, followed by spectral encoding via Poisson-Charlier polynomial approximation to enhance the feature representation. Furthermore, a sparse cross-attention mechanism is introduced to dynamically weight and integrate heterogeneous features from multiple sources. On a benchmark dataset with 8,720 associations, MVGSCA achieves an AUC of 96.32% and an AUPR of 95.69% under five-fold cross-validation, significantly outperforming six state-of-the-art methods.
