Step patterns

BasePattern

class logio.dynamic_time_warping.BasePattern

Step pattern base class. A BasePattern object lists the transitions allowed while searching for the minimum-distance path.

Methods Plot

_normalize

_get_array

__repr__ prints a user-readable description of the recurrence equation defined by the given pattern.

__init__()

property is_normalizable

plot()

Visualize step pattern.

UserStepPattern

class logio.dynamic_time_warping.UserStepPattern(pattern_info, normalize_guide)

__init__(pattern_info, normalize_guide)

User defined step pattern.

Parameters

• pattern_info (list) –

  list contains pattern information. example: the case of symmetric2 pattern: pattern_info = [

  dict(

  indices=[(-1,0),(0,0)], weights=[1]

  ), dict(

  indices=[(-1,-1),(0,0)], weights=[2]

  ), dict(

  indices=[(0,-1),(0,0)], weights=[1]

  )

  ]

• normalize_guide (string ('N','M','N+M','none')) – Guide to compute normalized distance.

property is_normalizable

label = 'user defined step pattern'

plot()

Visualize step pattern.
