Parameters
----------
fg_model_comps_dict: dict
dictionary with keys that are tuples of tuples of 2-tuples (thats right, 3 levels)
in the first level, each tuple represents a 'modeling group' visibilities in each
modeling group are represented by a set of basis vectors that span all baselines in that
group with elements raveled by baseline and then frequency. Each tuple in the modeling group is a
'redundant group' representing visibilities that we will represent with identical component coefficients
each element of each 'redundant group' is a 2-tuple antenna pair. Our formalism easily accomodates modeling
visibilities as redundant or non redundant (one simply needs to make each redundant group length 1).
use_redundancy: bool, optional
If False, break fitting groups with the same number of baselines in each redundant
sub_group into different fitting groups with no redundancy in each
redundant subgroup. This is to prevent fitting groups with single
redundant groups of varying lengths from being lumped into different chunks
increasing the number of chunks has a more significant impact on run-time
then increasing the number of baselines in each chunk.
default is False.
Returns:

Parameters
----------
fg_model_comps_dict: dict
dictionary where each key is a 2-tuple (nbl, nvecs) referring to the number
of baselines in each vector and the number of vectors. Each 2-tuple points to
a dictionary where each key is the fitting group in fg_comps_dict that includes
nbl baselines. Each key in the referenced dict points to an (nred_grps * nfreqs x nvecs)
numpy.ndarray describing the modeling components for each fitting group in the chunk.
ants_map: dict mapping integers to integers
map between each antenna number to a unique index between 0 and Nants_data
(typically the index of each antenna in ants_map)
nfreqs: int, optional
number of frequency channels
dtype: numpy.dtype
tensor data types
default is np.float32
Returns
-------
fg_model_comps: list
list of tf.Tensor objects where each tensor has shape (nvecs, ngrps, nbls, nfreqs)
where nbls varies from tensor to tensor. Fitting groups with vectors that span nbls are lumped into the same
modeling tensor along the ngrps axis. nvecs is chosen in chunk_fg_comp_dict_by_nbls
to be the maximum number of vectors representing any of the ngrps baseline grps
which means that many rows in nvecs will be zero. For example, if we are modeling with
vectors that all span nbls=1 baseline and using delay-modes to model our data
then nvecs will equal the largest number of delay modes necessary to model the wedge
on all baselines even though the short baselines are described by far fewer modes
on short baselines, most of the rows along the vector dimension will therefor be zero.
This is wasteful of memory but it allows us to take advantage of the fast
dense matrix operations on a GPU.

Parameters
----------
uvdata: UVData object
uvdata objet of data to be calibrated.
fg_model_comps_dict: dictionary
dictionary with keys that are tuples of tuples of 2-tuples (thats right, 3 levels)
in the first level, each tuple represents a 'modeling group' visibilities in each
modeling group are represented by a set of basis vectors that span all baselines in that
group with elements raveled by baseline and then frequency. Each tuple in the modeling group is a
'redundant group' representing visibilities that we will represent with identical component coefficients
each element of each 'redundant group' is a 2-tuple antenna pair. Our formalism easily accomodates modeling
visibilities as redundant or non redundant (one simply needs to make each redundant group length 1).
values are real numpy arrays with size (Ngrp * Nfreqs) * Ncomponents
gains: UVCal object
UVCal with initial gain estimates.
There many smart ways to obtain initial gain estimates
but this is beyond the scope of calamity (for example, firstcal, logcal, sky-based cal).
Users can determine initial gains with their favorite established cal algorithm.
default is None -> start with unity gains.
WARNING: At the present, the flags in gains are not propagated/used! Make sure flags in uvdata object!
freeze_model: bool, optional
Only optimize loss function wrt gain variables. This is effectively traditional model-based calibration
with sky_model as the model (but projected onto the foreground basis vectors).
default is False.
optimizer: string
Name of optimizer. See OPTIMIZERS dictionary which contains optimizers described in
https://www.tensorflow.org/api_docs/python/tf/keras/optimizers
default is 'Adamax'
tol: float, optional
halting condition for optimizer loop. Stop loop when the change in the cost function falls
below tol.
default is 1e-14
maxsteps: int, optional
maximum number of opt.minimize calls before halting.
default is 10000
include_autos: bool, optional
include autocorrelations in fitting.
default is False.
verbose: bool, optional
generate lots of text.
default is False.
sky_model: UVData object, optional
a sky-model to use for initial estimates of foreground coeffs and
to set overall flux scale and phases.
Note that this model is not used to obtain initial gain estimates.
These must be provided through the gains argument.
dtype: numpy dtype, optional
the float precision to be used in tensorflow gradient descent.
runtime scales roughly inversely linear with precision.
default is np.float32
use_min: bool, optional
If True, use the set of parameters that determine minimum as the ML params
If False, use the last set of parameters visited by the optimization loop.
use_redundancy: bool, optional
if true, solve for one set of foreground coeffs per redundant baseline group
instead of per baseline.
notebook_progressbar: bool, optional
use progress bar optimized for notebook output.
default is False.
red_tol: float, optional
tolerance for determining baselines redundant (meters)
default is 1.0
correct_resid: bool, optional
if True, gain correct residual.
default is False
correct_model: bool, optional
if True, gain correct model.
default is False
weights: UVFlag object, optional.
UVFlag weights object containing weights to use for data fitting.
default is None -> use nsamples * ~flags if nsamples_in_weights
or ~flags if not nsamples_in_weights
nsamples_in_weights: bool, optional
If True and weights is None, generate weights proportional to nsamples.
default is True.
graph_mode: bool, optional
if True, compile gradient update step in graph mode to speed up
runtime by ~2-3x. I've found that this helps on CPUs but on GPUs
it actually increases runtime by a similar factor.
n_profile_steps: bool, optional
number of steps to run profiling on
default is 0.
profile_log_dir: str, optional
directory to save profile logs to
default is './logdir'
model_regularization: str, optional
option to regularize model
supported 'post_hoc', 'sum'
default is 'post_hoc'
which sets sum of amps equal and sum of phases equal.
init_guesses_from_previous_time_step: bool, optional
if True, then use foreground coeffs and gains from previous time-step to
initialize gains for next time step.
skip_threshold: float, optional
if less then this fraction of data is unflagged on a particular poltime,
flag the entire poltime.
opt_kwargs: kwarg_dict
kwargs for tf.optimizers
Returns
-------
model: UVData object
uvdata object containing model of the foregrounds
resid: UVData object
uvdata object containing resids which are the data minus
the model with gains multiplied and then with the gains divided out.
gains: UVCal object
uvcal object containing estimates of the gain solutions. These solutions
are not referenced to any sky model and are likely orders of
fit_history:
dictionary containing fit history with fields:
