📊 Distributions
A distribution is just a map of where data tends to live.
🔔 The Normal (Gaussian) Distribution
The Bell Curve! Most people are average height, and very few are extremely short or tall. When initializing Neural Network weights, we usually pull numbers from a Normal distribution!
🐍 Python Implementation
We can generate and visualize these distributions using numpy and matplotlib.
import numpy as np
# Generate 1000 random weights from a Normal Distribution (mean=0, std=0.1)
weights = np.random.normal(loc=0.0, scale=0.1, size=1000)
print("First 5 weights:", weights[:5])
print("Mean of weights:", np.mean(weights)) # Should be close to 0
# If you wanted to plot this:
# import matplotlib.pyplot as plt
# plt.hist(weights, bins=50)
# plt.show()
