Overview This project involves analyzing and reducing the dimensionality of gene expression datasets in cancer using the K-means clustering algorithm. The dataset contains expression data for 20,531 genes across various cancer samples, each tagged with a label representing the cancer type (e.g., BRCA for breast cancer). Key steps include: Scaling features using MinMaxScaler. Reducing dimensionality with Principal Component Analysis (PCA). These techniques enhance the K-means algorithm's ability to identify patterns and cluster the data effectively.
