fca-algorithms 0.1.0

FCA basic algorithms

FCA utils

Module for FCA basics such as retrieving concepts, drawing a hasse diagram, etc

Getting formal concepts

from fca.api_models import Context

c = Context(O, A, I)
concepts = c.get_concepts(c)

Getting association rules

from fca.api_models import Context

c = Context(O, A, I)
c.solver.get_association_rules(c, min_support=0.4, min_confidence=1)

Drawing hasse diagram

from fca.plot.plot import plot_from_hasse
from fca.api_models import Context


c = Context(O, A, I)
hasse_lattice, concepts = c.get_lattice(c)
plot_from_hasse(hasse_lattice, concepts)

CLI

To plot a hasse diagram from a context

fca_cli -c input.csv --show_hasse

The context is expected to be a csv with the following format

name	attr1	attr2
obj1	x
obj2		x
obj3	x	x
obj4

TODO

• Make algorithms to be able to work with streams (big files)
