Merge branch 'pawel-czyz-additional-solvers-and-documentation' into devel
I have revised this PR (which was very nice, thanks). I have made some modifications including improvements in the normalization functions, documentation, and refactoring of qp.functional. I will leave this in devel until I find the time to "stress-test" the modifications. Thanks to Pawel Czyz for the nice contribution!

ensembles seem to be broken; they have an internal model selection which takes the parameters, but since quapy now
|
||||
works with protocols it would need to know the validation set in order to pass something like
|
||||
"protocol: APP(val, etc.)"
|
||||
sample_size should not be mandatory when qp.environ['SAMPLE_SIZE'] has been specified
|
||||
clean all the cumbersome methods that have to be implemented for new quantifiers (e.g., n_classes_ prop, etc.)
|
||||
make truly parallel the GridSearchQ
|
||||
make more examples in the "examples" directory
|
||||
merge with master, because I had to fix some problems with QuaNet due to an issue notified via GitHub!
|
||||
added cross_val_predict in qp.model_selection (i.e., a cross_val_predict for quantification) --would be nice to have
|
||||
it parallelized
|
||||
|
||||
check the OneVsAll module(s)
|
||||
|
||||
check the set_params de neural.py, because the separation of estimator__<param> is not implemented; see also
|
||||
__check_params_colision
|
||||
|
||||
HDy can be customized so that the number of bins is specified, instead of explored within the fit method
|
||||
|
||||
Packaging:
|
||||
==========================================
|
||||
Document methods with paper references
|
||||
unit-tests
|
||||
clean wiki_examples!
|
||||
|
||||
Refactor:
|
||||
==========================================
|
||||
Unify ThresholdOptimization methods, as an extension of PACC (and not ACC), the fit methods are almost identical and
|
||||
use a prob classifier (take into account that PACC uses pcc internally, whereas the threshold methods use cc
|
||||
instead). The fit method of ACC and PACC has a block for estimating the validation estimates that should be unified
|
||||
as well...
|
||||
Refactor protocols. APP and NPP related functionalities are duplicated in functional, LabelledCollection, and evaluation
|
||||
|
||||
|
||||
New features:
|
||||
==========================================
|
||||
Add "measures for evaluating ordinal"?
|
||||
Add datasets for topic.
|
||||
Do we want to cover cross-lingual quantification natively in QuaPy, or does it make more sense as an application on top?
|
||||
|
||||
Current issues:
|
||||
==========================================
|
||||
Revise the class structure of quantification methods and the methods they inherit... There is some confusion regarding
|
||||
methods isbinary, isprobabilistic, and the like. The attribute "learner_" in aggregative quantifiers is also
|
||||
confusing, since there is a getter and a setter.
|
||||
Remove the "deep" in get_params. There is no real compatibility with scikit-learn as for now.
|
||||
SVMperf-based learners do not remove temp files in __del__?
|
||||
In binary quantification (hp, kindle, imdb) we used F1 in the minority class (which in kindle and hp happens to be the
|
||||
negative class). This is not covered in this new implementation, in which the binary case is not treated as such, but as
|
||||
an instance of single-label with 2 labels. Check
|
||||
Add automatic reindex of class labels in LabelledCollection (currently, class indexes should be ordered and with no gaps)
|
||||
OVR I believe is currently tied to aggregative methods. We should provide a general interface also for general quantifiers
|
||||
Currently, being "binary" only adds one checker; we should figure out how to impose the check to be automatically performed
|
||||
Add random seed management to support replicability (see temp_seed in util.py).
|
||||
GridSearchQ is not trully parallelized. It only parallelizes on the predictions.
|
||||
In the context of a quantifier (e.g., QuaNet or CC), the parameters of the learner should be prefixed with "estimator__",
|
||||
in QuaNet this is resolved with a __check_params_colision, but this should be improved. It might be cumbersome to
|
||||
impose the "estimator__" prefix for, e.g., quantifiers like CC though... This should be changed everywhere...
|
||||
QuaNet needs refactoring. The base quantifiers ACC and PACC receive val_data with instances already transformed. This
|
||||
issue is due to a bad design.
|
||||
|
||||
Improvements:
|
||||
==========================================
|
||||
Explore the hyperparameter "number of bins" in HDy
|
||||
Rename EMQ to SLD ?
|
||||
Parallelize the kFCV in ACC and PACC?
|
||||
Parallelize model selection trainings
|
||||
We might want to think of (improving and) adding the class Tabular (it is defined and used on branch tweetsent). A more
|
||||
recent version is in the project ql4facct. This class is meant to generate latex tables from results (highligting
|
||||
best results, computing statistical tests, colouring cells, producing rankings, producing averages, etc.). Trying
|
||||
to generate tables is typically a bad idea, but in this specific case we do have pretty good control of what an
|
||||
experiment looks like. (Do we want to abstract experimental results? this could be useful not only for tables but
|
||||
also for plots).
|
||||
Add proper logging system. Currently we use print
|
||||
It might be good to simplify the number of methods that have to be implemented for any new Quantifier. At the moment,
|
||||
there are many functions like get_params, set_params, and, specially, @property classes_, which are cumbersome to
|
||||
implement for quick experiments. A possible solution is to impose get_params and set_params only in cases in which
|
||||
the model extends some "ModelSelectable" interface only. The classes_ should have a default implementation.
|
||||
|
||||
Checks:
|
||||
==========================================
|
||||
How many times is the system of equations for ACC and PACC not solved? How many times is it clipped? Do they sum up
|
||||
to one always?
|
||||
Re-check how hyperparameters from the quantifier and hyperparameters from the classifier (in aggregative quantifiers)
|
||||
is handled. In scikit-learn the hyperparameters from a wrapper method are indicated directly whereas the hyperparams
|
||||
from the internal learner are prefixed with "estimator__". In QuaPy, combinations having to do with the classifier
|
||||
can be computed at the begining, and then in an internal loop the hyperparams of the quantifier can be explored,
|
||||
passing fit_learner=False.
|
||||
Re-check Ensembles. As for now, they are strongly tied to aggregative quantifiers.
|
||||
Re-think the environment variables. Maybe add new ones (like, for example, parameters for the plots)
|
||||
Do we want to wrap prevalences (currently simple np.ndarray) as a class? This might be convenient for some interfaces
|
||||
(e.g., for specifying artificial prevalences in samplings, for printing them -- currently supported through
|
||||
F.strprev(), etc.). This might however add some overload, and prevent/difficult post processing with numpy.
|
||||
Would be nice to get a better integration with sklearn.

This example shows how to use Bayesian quantification (https://arxiv.org/abs/2302.09159),
|
||||
which is suitable for low-data situations and when the uncertainty of the prevalence estimate is of interest.
|
||||
|
||||
For this, we will need to install extra dependencies:
|
||||
|
||||
```
|
||||
$ pip install quapy[bayesian]
|
||||
```
|
||||
|
||||
Running the script via:
|
||||
|
||||
```
|
||||
$ python examples/bayesian_quantification.py
|
||||
```
|
||||
|
||||
will produce a plot `bayesian_quantification.pdf`.
|
||||
|
||||
Due to a low sample size and the fact that classes 2 and 3 are hard to distinguish,
|
||||
it is hard to estimate the proportions accurately, what is visible by looking at the posterior samples,
|
||||
showing large uncertainty.

:param str norm: the method to use for normalization.
|
||||
|
||||
* `clip`, the values are clipped to the range [0,1] and then L1-normalized.
|
||||
* `mapsimplex` projects vectors onto the probability simplex. This implementation relies on
|
||||
`Mathieu Blondel's projection_simplex_sort <https://gist.github.com/mblondel/6f3b7aaad90606b98f71>`_
|
||||
* `condsoftmax`, applies a softmax normalization only to prevalence vectors that lie outside the simplex
|
||||
|
||||
:param n_jobs: number of parallel workers
|
||||
:param solver: indicates the method to be used for obtaining the final estimates. The choice
|
||||
'exact' comes down to solving the system of linear equations :math:`Ax=B` where `A` is a
|
||||
matrix containing the class-conditional probabilities of the predictions (e.g., the tpr and fpr in
|
||||
binary) and `B` is the vector of prevalence values estimated via CC, as :math:`x=A^{-1}B`. This solution
|
||||
might not exist for degenerated classifiers, in which case the method defaults to classify and count
|
||||
(i.e., does not attempt any adjustment).
|
||||
Another option is to search for the prevalence vector that minimizes the L2 norm of :math:`|Ax-B|`. The latter
|
||||
is achieved by indicating solver='minimize'. This one generally works better, and is the default parameter.
|
||||
More details about this can be consulted in `Bunse, M. "On Multi-Class Extensions of Adjusted Classify and
|
||||
Count", on proceedings of the 2nd International Workshop on Learning to Quantify: Methods and Applications
