mapykoB 0.0.3

Package for sequence modeling with Andrei Markov's models

Description

Mapykob is a Python application that provides an easy way to experiment with Markov models. While built for educational purposes, it can both be used for educational or commercial purposes.PyPI hosting

Installation

To install mapykoB simply run the following command in a terminal window:

$  pip install mapykoB

If you would rather install from source, run the following commands in a terminal window:

$  git clone https://github.com/octoandzl/mapykoB.git
$  cd mapykob
$  python setup.py install

Usage

An example would be:

$  sample_data = np.array([
$    [1, 1, 1, 0, 0, 0, 0, 0],
$    [0, 1, 0, 0, 0, 1, 0, 0],
$    [0, 0, 0, 0, 0, 1, 0, 1],
$    [0, 0, 1, 0, 1, 1, 1, 1],
$    [0, 0, 0, 0, 1, 0, 1, 0],
$    [0, 1, 0, 0, 1, 1, 0, 1],
$    [0, 0, 0, 1, 1, 1, 0, 0]])

$  possible_observations = Counter(sample_data[i][j] for i in range(len(sample_data)) for j in range(len(sample_data[i])))
$  M = 2
$  V = len(possible_observations)
$  hmm_discreet = hmm_discreet(M,sample_data,V)
$  hmm_discreet.pi = np.array([0.5, 0.5])
$  hmm_discreet.A = np.array([[0.7, 0.3], [0.4, 0.6]])
$  hmm_discreet.B = np.array([[0.6, 0.4], [0.3, 0.7]])
$  hmm_discreet.compute_alpha(0)
$  p = hmm_discreet.compute_p_from_alpha(0)
