Embodiment 2
[0156] The excluded subjects are used to test the ability of the SVM classifier to reliably classify new cases. This process is repeated for each subject to obtain a relatively unbiased estimate of generalization ability. The performance of the algorithm can be measured by its sensitivity, Specificity, accuracy and AUC (area under receiver operating characteristic curve) are described.
[0157] Sensitivity is the proportion of all outcomes that the model correctly predicts with a true value of 1, and is calculated as:
[0158]
[0159] In contrast, specificity is the proportion of all outcomes where the model correctly predicts a true value of -1 (prediction is stable), and is calculated as:
[0160]
[0161] Among them, TP L represents the total number of experts predicted as experts, TN L Indicates the total number of normal controls predicted to be normal controls, FN L represents the total number of normal controls predicted to be experts, FP L Indicates the tota...
Embodiment 3
[0177] An embodiment of the present invention proposes a resting-state functional magnetic resonance data classification system for fused multi-scale information, including: a memory for storing instructions executable by a processor; and a processor for executing the instructions to achieve the above A method for classifying resting-state functional magnetic resonance data of the brain that fuses multi-scale information as described in Embodiment 1.
[0178] A brain resting state fMRI data classification system incorporating multi-scale information may include an internal communication bus, a processor, a read only memory (ROM), a random access memory (RAM), a communication port, and a hard disk. The internal communication bus can realize data communication between components of a brain resting-state fMRI data classification system that integrates multi-scale information. The processor can make judgments and issue prompts. In some embodiments, a processor may consist of one ...
