| Medium | GrooveSquid.com (original content) | Medium Difficulty Summary A novel anomaly detection method called MEATRD is proposed to detect anomalous tissue regions (ATRs) in clinical diagnosis and pathological studies. The approach integrates histology images and spatial transcriptomics (ST) data, which provides a molecular perspective for detecting ATRs. MEATRD reconstructs image patches and gene expression profiles of normal tissue spots from multimodal embeddings and learns a one-class classification AD model based on latent multimodal reconstruction errors. This strategy combines the strengths of reconstruction-based and one-class classification approaches. The method utilizes an innovative masked graph dual-attention transformer (MGDAT) network, which facilitates cross-modality and cross-node information sharing while addressing over-generalization issues. MEATRD is evaluated across eight real ST datasets, demonstrating superior performance in ATR detection compared to various state-of-the-art AD methods. |
| Low | GrooveSquid.com (original content) | Low Difficulty Summary A new way to find abnormal tissue regions has been developed using a combination of image analysis and gene expression data. This method, called MEATRD, looks at both images and genetic information to identify areas that are different from normal tissue. It uses a special type of computer network to combine this information and make predictions about which areas are abnormal. The results show that MEATRD is better than other methods at finding these abnormal areas. |
