Train a k-Means model on the data

This case-study examines the patterns, symmetries, associations and causality in a rare but devastating disease, amyotrophic lateral sclerosis (ALS). A major clinically relevant question in this biomedical study is: What patient phenotypes can be automatically and reliably identified and used to predict the change of the ALSFRS slope over time?. This problem aims to explore the data set by unsupervised learning (you only need to work on K mean in this assignment).

Load and prepare the data.
Perform summary and preliminary visualization (i.e. show the clustering with selected features).
Train a k-Means model on the data with selected features (3 or more), experiment at least two different k values, and explain which k value is a better choice.
Evaluating the model performance by report the center of clusters.
Visualize the final clustering result.
