Usage

from linear_segment import segment
import numpy as np

# Create data
np.random.seed(10)
x = np.random.random(300000)
x[10000:20000] = x[10000:20000] + 0.1
x[25000:27000] = x[25000:27000] - 1
labels = np.repeat('a', len(x))

# Calculate segments
segments = segment(x, labels, method="online_both")
segments
segments = segment(x, labels, method="cbs")
