This article explains Pair Plots (Scatter Matrices) in Python for exploratory data analysis, showing pairwise relationships between numerical variables using scatter plots and distribution plots.
The article provides the following Python code using `seaborn` and `matplotlib` to create a pair plot:
```python
import seaborn as sns
import matplotlib.pyplot as plt
import pandas as pd
import numpy as np
# Create some random data
data = np.random.rand(100, 4)
df = pd.DataFrame(data, columns= 'A', 'B', 'C', 'D' » )
# Create the pair plot
sns.pairplot(df)
# Show the plot
plt.show()
```
The author discusses a shift in approach to clustering mixed data, advocating for starting with the simpler Gower distance metric before resorting to more complex embedding techniques like UMAP. They introduce 'Gower Express', an optimized and accelerated implementation of Gower.
This article introduces interpretable clustering, a field that aims to provide insights into the characteristics of clusters formed by clustering algorithms. It discusses the limitations of traditional clustering methods and highlights the benefits of interpretable clustering in understanding data patterns.
