Install Binary Distribution

Currently, only 64-bit binary distribution is provided. Run pip install ace_cream to install the binary distribution.

How to build

You need numpy and fortran compiler to build from source.

brew install gcc

sudo apt-get install gfortran

How to use

import numpy as np
from ace_cream import ace_cream
# discrete case, binary symmetric channel with crossover probability 0.1
x = np.random.choice([0,1], size=N_SIZE)
n = np.random.choice([0,1], size=N_SIZE, p=[0.9, 0.1])
y = np.mod(x + n, 2)
# set both x(cat=0) and y(cat=-1) as categorical type
tx, ty = ace_cream(x, y, cat=[-1,0])

# continuous case
x = np.random.uniform(0, np.pi, 200)
y = np.exp(np.sin(x)+np.random.normal(size=200)/2)
tx, ty = ace_cream(x, y)
