`salvus.opt.data_normalizations.l2_energy_per_measurement`

L2 energy per measurement data normalization and its jacobian.

Functions

`forward_data_normalization_l2_energy_per_measurement()`

def forward_data_normalization_l2_energy_per_measurement(
    data_synthetic: numpy.ndarray,
    data_observed: numpy.ndarray,
    sampling_rate_in_hertz: float,
) -> builtins.tuple: ...

Normalize a data trace by its L2 energy norm.

Parameters

data_synthetic numpy.ndarray — The synthetic data trace without normalization.
data_observed numpy.ndarray — The observed data trace without normalization.
sampling_rate_in_hertz float — The sampling rate of both data traces in Hz.

Returns builtins.tuple
