adaptive.IntegratorLearner#
- class adaptive.IntegratorLearner(function: Callable, bounds: tuple[int, int], tol: float)[source]#
Bases:
BaseLearner
- ask(n: int, tell_pending: bool = True) tuple[list[float], list[float]] [source]#
Choose points for learners.
- load_dataframe(df: DataFrame, with_default_function_args: bool = True, function_prefix: str = 'function.', x_name: str = 'x', y_name: str = 'y') None [source]#
Load data from a
pandas.DataFrame
.If
with_default_function_args
is True, thenlearner.function
’s default arguments are set (usingfunctools.partial
) from the values in thepandas.DataFrame
.- Parameters:
with_default_function_args (bool, optional) – Include the
learner.function
’s default arguments as a column, by default Truefunction_prefix (str, optional) – Prefix to the
learner.function
’s default arguments’ names, by default “function.”x_name (str, optional) – Name of the input value, by default “x”
y_name (str, optional) – Name of the output value, by default “y”
- loss(real=True)[source]#
Return the loss for the current state of the learner.
- Parameters:
real (bool, default: True) – If False, return the “expected” loss, i.e. the loss including the as-yet unevaluated points (possibly by interpolation).
- new() IntegratorLearner [source]#
Create a copy of
Learner2D
without the data.
- tell(point: float, value: float) None [source]#
Tell the learner about a single value.
- Parameters:
x (A value from the function domain) –
y (A value from the function image) –
- tell_pending()[source]#
Tell the learner that ‘x’ has been requested such that it’s not suggested again.
- to_dataframe(with_default_function_args: bool = True, function_prefix: str = 'function.', x_name: str = 'x', y_name: str = 'y') DataFrame [source]#
Return the data as a
pandas.DataFrame
.- Parameters:
with_default_function_args (bool, optional) – Include the
learner.function
’s default arguments as a column, by default Truefunction_prefix (str, optional) – Prefix to the
learner.function
’s default arguments’ names, by default “function.”x_name (str, optional) – Name of the input value, by default “x”
y_name (str, optional) – Name of the output value, by default “y”
- Return type:
pandas.DataFrame
- Raises:
ImportError – If
pandas
is not installed.
