Pen'n'paper
Pen'n'paper is a package to easily collect the data about (noisy) processes and plot them for comparison. This package is not aiming at feature completeness. Instead it should give you an easy start during the phase of the project when you want to just concentrate on an experimental idea.
Installation:
pip install pennpaper
By example:
# We have a mysterious function that we would like to better understand on the interval [0.1, 5.].
# Unfortunately the function is noisy.
import numpy as np
X = np.arange(0.1, 5, step=0.01)
import random
def noisy_mapping(mapping):
def _(x):
y = mapping(x)
y += random.gauss(0, 1)
return y
return _
pow2 = noisy_mapping(lambda x: x ** 2)
# lets record the pairs (x, f(x)) in a metric and make a plot:
from pennpaper import Metric, plot_group, plot
m1 = Metric("pow2")
for x in X:
m1.add_record(x, pow2(x))
plot(m1)
# try again - see in how far it repeats itself.
m2 = Metric("pow2_second_try")
for x in X:
m2.add_record(x, pow2(x))
# lets plot two metrics side-by-side
plot_group([m1, m2])
# Actually, m1 and m2 are metrics of the same process.
# What if we create a new metric tracking the mean and stddev of this process?
m3 = m1 + m2
plot(m3)
# the plot is too noisy to understand. We can smoothen it!
plot(m3, smoothen=True)
