- Use the StandardScaler() module from scikit-learn to normalize the data from the CSV file.
- Create a DataFrame with the scaled data and set the "coin_id" index from the original DataFrame as the index for the new DataFrame.
- Create a list with the number of k values from 1 to 11.
- Create an empty list to store the inertia values.
- Create a for loop to compute the inertia with each possible value of k.
- Create a dictionary with the data to plot the elbow curve.
- Plot a line chart with all the inertia values computed with the different values of k to visually identify the optimal value for k.
- Initialize the K-means model with the best value for k.
- Fit the K-means model using the original scaled DataFrame.
- Predict the clusters to group the cryptocurrencies using the original scaled DataFrame.
- Create a copy of the original data and add a new column with the predicted clusters.
- Create a scatter plot using hvPlot
- Using the original scaled DataFrame, perform a PCA and reduce the features to three principal components.
- Retrieve the explained variance to determine how much information can be attributed to each principal component
- Create a new DataFrame with the PCA data and set the "coin_id" index from the original DataFrame as the index for the new DataFrame.
- Create a list with the number of k-values from 1 to 11.
- Create an empty list to store the inertia values.
- Create a for loop to compute the inertia with each possible value of k.
- Create a dictionary with the data to plot the Elbow curve.
- Plot a line chart with all the inertia values computed with the different values of k to visually identify the optimal value for k.
- Initialize the K-means model with the best value for k.
- Fit the K-means model using the PCA data.
- Predict the clusters to group the cryptocurrencies using the PCA data.
- Create a copy of the DataFrame with the PCA data and add a new column to store the predicted clusters.
- Create a scatter plot using hvPlot as follows:
- Set the x-axis as "price_change_percentage_24h" and the y-axis as "price_change_percentage_7d".
- Color the graph points with the labels found using K-means.
- Add the "coin_id" column in the hover_cols parameter to identify the cryptocurrency represented by each data point.
