0Machine Learning in Medical Imaging: A Comparative Review of Agglomerative and K-Means Clustering Techniques
Layman's Abstract: This study looks at two popular ways to help computers identify brain tumors in MRI scans. The two methods used are called agglomerative clustering and K-means clustering. These techniques are both types of "unsupervised learning," meaning they don't require prior knowledge about the tumors. The MRI images were processed to remove noise and improve clarity before being analyzed by these algorithms.
Agglomerative clustering worked well for identifying irregularly shaped tumors, while K-means clustering was faster and better at detecting more uniformly shaped tumors. The results showed that each method had its own strengths. For instance, K-means is quicker and better for tumors that are round and similar in size, but agglomerative clustering is better for tumors with odd shapes. Experts in the field reviewed the results and confirmed the findings. This study could help improve the accuracy of tumor detection, supporting doctors in making better decisions for patient care. Future research could combine these methods with newer technologies, like deep learning, to make detection even more accurate.

------------
In this video, we explore two key machine learning techniques β Agglomerative Clustering and K-Means Clustering β used for detecting brain tumors in MRI scans. Both techniques fall under unsupervised learning, which means they donβt require pre-labeled data to identify tumors. The comparison highlights how Agglomerative Clustering is better suited for irregularly shaped tumors, while K-Means excels at detecting round, uniform tumors quickly. Experts reviewed these findings, supporting their potential for improving tumor detection accuracy. Stay tuned for insights into how these methods could be combined with newer technologies like deep learning for even more precise medical diagnoses.
