Research on Adverse Drug Reaction Prediction Model Combining Knowledge Graph Embedding and Deep Learning
In response to the problems in previous studies that features are high-dimensional and sparse, independent prediction models need to be constructed for each adverse reaction of drugs, and the prediction accuracy is low, this paper develops an adverse drug reaction prediction model based on knowledge graph embedding and deep learning, which can predict experimental results.

Recommender systems are indispensable in the realm of online applications, and sequential recommendation has enjoyed considerable prevalence due to its capacity to encapsulate the dynamic shifts in user interests.
Emulating Reader Behaviors for Fake News Detection
To this end, we propose an approach of Emulating the behaviors of readers (Ember) for fake news detection on social media, incorporating readers' reading and verificating process to model news from the component perspective thoroughly.
Perfused and Nonperfused Microaneurysms Identified and Characterized by Structural and Angiographic OCT
Although not all MAs seen with FA were identified with OCT, some MAs seen with OCT were not visible with FA or FP.
Debiasing Recommendation by Learning Identifiable Latent Confounders
Confounding bias arises due to the presence of unmeasured variables (e. g., the socio-economic status of a user) that can affect both a user's exposure and feedback.
Efficient Bi-Level Optimization for Recommendation Denoising
To efficiently solve this bi-level optimization problem, we employ a weight generator to avoid the storage of weights and a one-step gradient-matching-based loss to significantly reduce computational time.

Path-Based Reasoning over Heterogeneous Networks for Recommendation via Bidirectional Modeling
Despite their effectiveness, these models are often confronted with the following limitations: (1) Most prior path-based reasoning models only consider the influence of the predecessors on the subsequent nodes when modeling the sequences, and ignore the reciprocity between the nodes in a path; (2) The weights of nodes in the same path instance are usually assumed to be constant, whereas varied weights of nodes can bring more flexibility and lead to expressive modeling; (3) User-item interactions are noisy, but they are often indiscriminately exploited.
