Receiver Operating Characteristic Plot

Receiver Operating Characteristic Plot

A ROC (Receiver Operating Characteristic) plot is a graphical tool used to assess the performance of a binary classification model by illustrating the trade-off between sensitivity (true positive rate) and specificity (false positive rate). By plotting sensitivity against 1 - specificity across various threshold settings, the ROC curve shows how well the model distinguishes between classes, with a curve closer to the top-left corner indicating a more accurate model. The area under the ROC curve...

Classification of Illness

Classification of Illness

The meaning of illness is individualized to each person who experiences an alteration in health. In contrast, disease is a medical term indicating a pathological change in the structure and function of the body or mind. It is a condition that has specific symptoms and boundaries.
An illness is a response to a disease in which the person's level of functioning is changed compared with a previous level. The general classification of illness includes acute and chronic.
Acute illness is severe and...

Background:

Gene expression data are vital for disease diagnosis.
Current methods using Convolutional Neural Networks (CNNs) for gene expression data face challenges in capturing complex spatial gene relationships and optimizing image representations.
Existing spatial arrangements in gene expression images are often fixed and suboptimal, limiting learning of spatial dependencies.

Purpose of the Study:

To propose a novel method, Feature Transformation Network based on Correlation Distribution Graph (FTNCDG), for converting high-dimensional gene expression data into image-like representations.
To enhance CNN-based classification accuracy for disease diagnosis by addressing limitations in existing gene-to-image transformation methods.
To integrate biological context into spatial encoding for improved diagnostic performance.

Main Methods:

Developed FTNCDG to convert gene expression data into image representations suitable for CNNs.
Integrated gene screening and relation extraction to identify disease-relevant gene sets with shared biological functions.
Employed a graph attention network-based coordinate search algorithm for optimal gene assignment to 2D image coordinates with minimal overlap.

Main Results:

Evaluated FTNCDG on four datasets (TCGA-BRCA, TCGA-LUAD, GSE96058, GSE25066) demonstrating high diagnostic accuracies.
Achieved superior performance compared to state-of-the-art methods across accuracy, AUC, F1-score, and recall metrics.
FTNCDG-CNN achieved accuracies ranging from 0.845 to 0.965 and AUC values from 0.814 to 0.954.

Conclusions:

FTNCDG-CNN significantly outperforms existing methods in disease diagnosis using gene expression data.
Incorporating biological context and optimizing spatial encoding are crucial for effective gene-to-image modeling.
The proposed method establishes a new benchmark for intelligent gene-to-image transformation in medical research.
