Background:

Brain tumors are a leading global cause of cancer mortality.
Early detection of brain tumors significantly increases patient survival rates.
Accurate classification of tumor types (pituitary, meningioma, glioma) is crucial for effective treatment.

Purpose of the Study:

To introduce a novel feature extraction method, reconstruction independent component analysis (RICA), for multi-class brain tumor detection.
To evaluate the efficacy of machine learning classifiers, specifically Support Vector Machine (SVM) and Linear Discriminant Analysis (LDA), in classifying brain tumor types using RICA features.
To assess the diagnostic performance of the proposed RICA-based methodology for differentiating between pituitary, meningioma, and glioma.

Main Methods:

Proposed a novel reconstruction independent component analysis (RICA) for feature extraction from brain tumor images.
Employed Support Vector Machine (SVM) with quadratic and linear kernels, and Linear Discriminant Analysis (LDA) for classification.
Utilized 10-fold cross-validation for robust training and testing data validation.

Main Results:

Achieved high accuracy in multi-class brain tumor classification: pituitary (99.34%), meningioma (96.96%), and glioma (95.88%).
Demonstrated excellent performance metrics, including sensitivity (97.78%), specificity (100%), and AUC (up to 0.9892 for pituitary).
The RICA feature extraction method proved effective in distinguishing between different brain tumor types.

Conclusions:

The proposed RICA feature-based methodology shows significant potential for improving the diagnostic efficiency of multi-class brain tumor detection.
This approach can enhance prediction accuracy, contributing to better clinical outcomes.
The study highlights the value of advanced feature extraction techniques combined with machine learning for brain tumor classification.
