Accurate identification of subtypes is of great importance for revealing the molecular mechanisms underlying complex diseases. Designing computational methods for cell type identification has been a hot topic recently, and various computational algorithms have been designed to estimate cell type composition. However, owing to the high sparseness, noise, and dimensionality of the obtainable scRNA-seq data, boosting prediction performance remains a challenge. In this work, a new cell type identification method is developed by integrating low rank representation (LRR) and symmetric orthogonal decomposition, named LRRS. Different from the spectral embedding algorithm in which the number of clusters is predefined, LRRS introduces a new orthogonal symmetric decomposition strategy and adaptively characterizes the local properties by measuring the weighted distance under the orthogonal space. To optimize the graph model, an efficient iterative approach is proposed to optimize each variable alternatively utilizing the alternating direction method of multipliers (ADMM). Based on the resulting similarity matrix, the spectral algorithm is adopted to group the individual cells. To evaluate the performance of LRRS, we implemented it on the eleven benchmark datasets and compared it with fourteen other cutting-edge methods in terms of prediction accuracy and normalized mutual information.

Currently, artificial intelligence (AI) technology combined with optical coherence tomography (OCT) and visual field testing is widely used for glaucoma progression prediction. However, the lack of labeled patient data and the ambiguity of structural differences in glaucoma remain major research bottlenecks. To address this, this paper proposes a glaucoma progression prediction method based on a semi-supervised reinforcement learning (SSRL) framework. In the SSRL framework, we design a key experience filtering strategy (KEFS) that prioritizes high-value training samples to enhance the model's generalization ability and optimize the quality of pseudo-labels. Additionally, an entropy regularization technique is introduced to encourage high-entropy distributions, preventing the model from prematurely converging to specific decisions and improving its ability to explore unlabeled data. To adapt the classifier and the pseudo-label generator within the SSRL framework, we innovatively propose the IncepMambaNet multi-scale network. This network integrates the visual state space (VSS) module from the VMamba model with traditional CNN structures, designing a four-branch IncepMamba module that leverages the strengths of both approaches. Experimental results demonstrate that compared to traditional supervised learning methods, our SSRL model effectively improves the performance of various state-of-the-art (SOTA) supervised classification networks. Furthermore, compared to various SOTA classification networks, IncepMambaNet achieves leading performance in three key metrics-macro-F1, F2-score, and AUC-by 0.8%, 8.8%, and 0.9%, respectively, showcasing outstanding feature capture capability and generalization performance.

Functional Magnetic Resonance Imaging (fMRI), measuring brain blood-oxygen level changes over time, is a powerful AD-diagnosis tool. However, current fMRI-based AD diagnosis methods rely on noise-susceptible time-domain features and focus only on synchronous brain-region interactions in the same time phase, neglecting asynchronous ones. To overcome these issues, we propose Frequency-Time Fusion Graph Neural Network (FTF-GNN). It integrates frequency- and time-domain features for robust AD classification, considering both asynchronous and synchronous brain-region interactions. First, we construct a fully connected hypervariate graph, where nodes represent brain regions and their Blood Oxygen Level-Dependent (BOLD) values at a time series point. A Discrete Fourier Transform (DFT) transforms these BOLD values from the spatial to the frequency domain for frequency-component analysis. Second, a Fourier-based Graph Neural Network (FourierGNN) processes the frequency features to capture asynchronous brain region connectivity patterns. Third, these features are converted back to the time domain and reshaped into a matrix where rows represent brain regions and columns represent their frequency-domain features at each time point. Each brain region then fuses its frequency-domain features with position encoding along the time series, preserving temporal and spatial information. Next, we build a brain-region network based on synchronous BOLD value associations and input the brain-region network and the fused features into a Graph Convolutional Network (GCN) to capture synchronous brain region connectivity patterns. Finally, a fully connected network classifies the brain-region features. Experiments on the Alzheimer's Disease Neuroimaging Initiative (ADNI) dataset demonstrate the method's effectiveness: Our model achieves 91.26% accuracy and 96.79% AUC in AD versus Normal Control (NC) classification, showing promising performance. For early-stage detection, it attains state-of-the-art performance in distinguishing NC from Late Mild Cognitive Impairment (LMCI) with 87.16% accuracy and 93.22% AUC. Notably, in the challenging task of differentiating LMCI from AD, FTF-GNN achieves optimal performance (85.30% accuracy, 94.56% AUC), while also delivering competitive results (77.40% accuracy, 91.17% AUC) in distinguishing Early MCI (EMCI) from LMCI-the most clinically complex subtype classification.

Additionally, the final similarity matrix is obtained by applying the angular alignment strategy on the similarity matrix.

This results in increased data sparsity and compromises the accuracy of subsequent analyses. Thus, a novel method, MoDET (Dual-level Momentum Distillation Method with Extreme Thresholding), has been proposed. MoDET employs a label-guided model and an extreme threshold mechanism to enhance cellular representation learning. Experiments demonstrate that MoDET significantly improves clustering performance of the gene expression matrix, with enhancements ranging from 3% to 20% across seven real-world datasets. Cross-batch training and evaluation experiments demonstrated that MoDET effectively mitigates batch effects, achieving an average performance improvement of 5%-7%. Concurrently, it exhibits superior accuracy in identifying rare cell types, outperforming other methods by 3%-20%. Ablation studies confirm that the dual-level momentum distillation boosts performance by 4%-20%, and the extreme threshold mechanism adds an additional 2%-15% improvement. Interpretability analysis shows that the extreme threshold makes the model's decision-making process more transparent.
