Kernel

kernel_double

class dcgpy.kernel_double(callable_f, callable_s, name)

The function defining the generic CGP node

Constructs a kernel function from callables.

Parameters

• callable_f (callable - List[double] -> double) – a callable taking a list of double as inputs and returning a double (the value of the kernel function evaluated on the inputs)

• callable_s (callable - List[string] -> string) – a callable taking a list of string as inputs and returning a string (the symbolic representation of the kernel function evaluated on the input symbols)

• name (string) – name of the kernel

Examples:

>>> from dcgpy import *
>>> def my_sum(x):
...     return sum(x)
>>> def print_my_sum(x):
...     s = "+"
...     return "(" + s.join(x) + ") "
>>> my_kernel = kernel_double(my_sum, print_my_sum, "my_sum")

kernel_gdual_double

class dcgpy.kernel_gdual_double(callable_f, callable_s, name)

The function defining the generic CGP node

Constructs a kernel function from callables.

Parameters

• callable_f (callable - List[gdual_double] -> gdual_double) – a callable taking a list of gdual_double as inputs and returning a gdual_double (the value of the kernel function evaluated on the inputs)

• callable_s (callable - List[string] -> string) – a callable taking a list of string as inputs and returning a string (the symbolic representation of the kernel function evaluated on the input symbols)

• name (string) – name of the kernel

Examples:

>>> from dcgpy import *
>>> def my_sum(x):
...     return sum(x)
>>> def print_my_sum(x):
...     s = "+"
...     return "(" + s.join(x) + ") "
>>> my_kernel = kernel_gdual_double(my_sum, print_my_sum, "my_sum")

kernel_gdual_vdouble

class dcgpy.kernel_gdual_vdouble(callable_f, callable_s, name)

The function defining the generic CGP node

Constructs a kernel function from callables.

Parameters

• callable_f (callable - List[gdual_vdouble] -> gdual_vdouble) – a callable taking a list of gdual_vdouble as inputs and returning a gdual_vdouble (the value of the kernel function evaluated on the inputs)

• callable_s (callable - List[string] -> string) – a callable taking a list of string as inputs and returning a string (the symbolic representation of the kernel function evaluated on the input symbols)

• name (string) – name of the kernel

Examples:

>>> from dcgpy import *
>>> def my_sum(x):
...     return sum(x)
>>> def print_my_sum(x):
...     s = "+"
...     return "(" + s.join(x) + ") "
>>> my_kernel = kernel_gdual_vdouble(my_sum, print_my_sum, "my_sum")
