## [Unreleased]
## [1.0.6] 2024-11-23
### Fixed
- Prevent existing edges to be added to the network in the `add_edge` method.
- Don't allow to add nodes or edges on already fiited networks.
- Number of threads spawned
- Network class tests
### Added
- Library logo generated with <https://openart.ai> to README.md
- Link to the coverage report in the README.md coverage label.
- *convergence_best* hyperparameter to the BoostAODE class, to control the way the prior accuracy is computed if convergence is set. Default value is *false*.
- SPnDE model.
- A2DE model.
- BoostA2DE model.
- A2DE & SPnDE tests.
- Add tests to reach 99% of coverage.
- Add tests to check the correct version of the mdlp, folding and json libraries.
- Library documentation generated with Doxygen.
- Link to documentation in the README.md.
- Three types of smoothing the Bayesian Network ORIGINAL, LAPLACE and CESTNIK.
### Internal
- Fixed doxygen optional dependency
- Add env parallel variable to Makefile
- Add CountingSemaphore class to manage the number of threads spawned.
- Ignore CUDA language in CMake CodeCoverage module.
- Update mdlp library as a git submodule.
- Create library ShuffleArffFile to limit the number of samples with a parameter and shuffle them.
- Refactor catch2 library location to test/lib
- Refactor loadDataset function in tests.
- Remove conditionalEdgeWeights method in BayesMetrics.
- Refactor Coverage Report generation.
- Add devcontainer to work on apple silicon.
- Change build cmake folder names to Debug & Release.
- Add a Makefile target (doc) to generate the documentation.
- Add a Makefile target (doc-install) to install the documentation.
### Libraries versions
- mdlp: 2.0.1
- Folding: 1.1.0
- json: 3.11
- ArffFiles: 1.1.0
## [1.0.5] 2024-04-20
### Added
- Install command and instructions in README.md
- Prefix to install command to install the package in the any location.
- The 'block_update' hyperparameter to the BoostAODE class, to control the way weights/significances are updated. Default value is false.
- Html report of coverage in the coverage folder. It is created with *make viewcoverage*
- Badges of coverage and code quality (codacy) in README.md. Coverage badge is updated with *make viewcoverage*
- Tests to reach 97% of coverage.
- Copyright header to source files.
- Diagrams to README.md: UML class diagram & dependency diagram
- Action to create diagrams to Makefile: *make diagrams*
### Changed
- Sample app now is a separate target in the Makefile and shows how to use the library with a sample dataset
- The worse model count in BoostAODE is reset to 0 every time a new model produces better accuracy, so the tolerance of the model is meant to be the number of **consecutive** models that produce worse accuracy.
- Default hyperparameter values in BoostAODE: bisection is true, maxTolerance is 3, convergence is true
### Removed
- The 'predict_single' hyperparameter from the BoostAODE class.
- The 'repeatSparent' hyperparameter from the BoostAODE class.
## [1.0.4] 2024-03-06
### Added
- Change *ascending* hyperparameter to *order* with these possible values *{"asc", "desc", "rand"}*, Default is *"desc"*.
- Add the *predict_single* hyperparameter to control if only the last model created is used to predict in boost training or the whole ensemble (all the models built so far). Default is true.
- sample app to show how to use the library (make sample)
### Changed
- Change the library structure adding folders for each group of classes (classifiers, ensembles, etc).
- The significances of the models generated under the feature selection algorithm are now computed after all the models have been generated and an &alpha;<sub>t</sub> value is computed and assigned to each model.
## [1.0.3] 2024-02-25
### Added
- Voting / probability aggregation in Ensemble classes

# BoostAODE Algorithm Operation
## Hyperparameters
The hyperparameters defined in the algorithm are:
- ***bisection*** (*boolean*): If set to true allows the algorithm to add *k* models at once (as specified in the algorithm) to the ensemble. Default value: *true*.
- ***bisection_best*** (*boolean*): If set to *true*, the algorithm will take as *priorAccuracy* the best accuracy computed. If set to *false⁺ it will take the last accuracy as *priorAccuracy*. Default value: *false*.
- ***order*** (*{"asc", "desc", "rand"}*): Sets the order (ascending/descending/random) in which dataset variables will be processed to choose the parents of the *SPODEs*. Default value: *"desc"*.
- ***block_update*** (*boolean*): Sets whether the algorithm will update the weights of the models in blocks. If set to false, the algorithm will update the weights of the models one by one. Default value: *false*.
- ***convergence*** (*boolean*): Sets whether the convergence of the result will be used as a termination condition. If this hyperparameter is set to true, the training dataset passed to the model is divided into two sets, one serving as training data and the other as a test set (so the original test partition will become a validation partition in this case). The partition is made by taking the first partition generated by a process of generating a 5 fold partition with stratification using a predetermined seed. The exit condition used in this *convergence* is that the difference between the accuracy obtained by the current model and that obtained by the previous model is greater than *1e-4*; otherwise, one will be added to the number of models that worsen the result (see next hyperparameter). Default value: *true*.
- ***maxTolerance*** (*int*): Sets the maximum number of models that can worsen the result without constituting a termination condition. if ***bisection*** is set to *true*, the value of this hyperparameter will be exponent of base 2 to compute the number of models to insert at once. Default value: *3*
- ***select_features*** (*{"IWSS", "FCBF", "CFS", ""}*): Selects the variable selection method to be used to build initial models for the ensemble that will be included without considering any of the other exit conditions. Once the models of the selected variables are built, the algorithm will update the weights using the ensemble and set the significance of all the models built with the same &alpha;<sub>t</sub>. Default value: *""*.
- ***threshold*** (*double*): Sets the necessary value for the IWSS and FCBF algorithms to function. Accepted values are:
- IWSS: $threshold \in [0, 0.5]$
- FCBF: $threshold \in [10^{-7}, 1]$
Default value is *-1* so every time any of those algorithms are called, the threshold has to be set to the desired value.
- ***predict_voting*** (*boolean*): Sets whether the algorithm will use *model voting* to predict the result. If set to false, the weighted average of the probabilities of each model's prediction will be used. Default value: *false*.

@brief a template for a bidirectional iterator for the @ref basic_json class
This class implements a both iterators (iterator and const_iterator) for the
@ref basic_json class.
@note An iterator is called *initialized* when a pointer to a JSON value has
been set (e.g., by a constructor or a copy assignment). If the iterator is
default-constructed, it is *uninitialized* and most methods are undefined.
**The library uses assertions to detect calls on uninitialized iterators.**
@requirement The class satisfies the following concept requirements:
-
[BidirectionalIterator](https://en.cppreference.com/w/cpp/named_req/BidirectionalIterator):
The iterator that can be moved can be moved in both directions (i.e.
incremented and decremented).
@since version 1.0.0, simplified in version 2.0.9, change to bidirectional
iterators in version 3.0.0 (see https://github.com/nlohmann/json/issues/593)

@brief internal implementation of the serialization function
This function is called by the public member function dump and organizes
the serialization internally. The indentation level is propagated as
additional parameter. In case of arrays and objects, the function is
called recursively.
- strings and object keys are escaped using `escape_string()`
- integer numbers are converted implicitly via `operator<<`
- floating-point numbers are converted to a string using `"%g"` format
- binary values are serialized as objects containing the subtype and the
byte array
@param[in] val value to serialize
@param[in] pretty_print whether the output shall be pretty-printed
@param[in] ensure_ascii If @a ensure_ascii is true, all non-ASCII characters
in the output are escaped with `\uXXXX` sequences, and the result consists
of ASCII characters only.
@param[in] indent_step the indent level
@param[in] current_indent the current indent level (only used internally)

@brief check whether a string is UTF-8 encoded
The function checks each byte of a string whether it is UTF-8 encoded. The
result of the check is stored in the @a state parameter. The function must
be called initially with state 0 (accept). State 1 means the string must
be rejected, because the current byte is not allowed. If the string is
completely processed, but the state is non-zero, the string ended
prematurely; that is, the last byte indicated more bytes should have
followed.
@param[in,out] state the state of the decoding
@param[in,out] codep codepoint (valid only if resulting state is UTF8_ACCEPT)
@param[in] byte next byte to decode
@return new state

@brief the JSON type enumeration
This enumeration collects the different JSON types. It is internally used to
distinguish the stored values, and the functions @ref basic_json::is_null(),
@ref basic_json::is_object(), @ref basic_json::is_array(),
@ref basic_json::is_string(), @ref basic_json::is_boolean(),
@ref basic_json::is_number() (with @ref basic_json::is_number_integer(),
@ref basic_json::is_number_unsigned(), and @ref basic_json::is_number_float()),
@ref basic_json::is_discarded(), @ref basic_json::is_primitive(), and
@ref basic_json::is_structured() rely on it.
@note There are three enumeration entries (number_integer, number_unsigned, and
number_float), because the library distinguishes these three types for numbers:
@ref basic_json::number_unsigned_t is used for unsigned integers,
@ref basic_json::number_integer_t is used for signed integers, and
@ref basic_json::number_float_t is used for floating-point numbers or to
approximate integers which do not fit in the limits of their respective type.
@sa see @ref basic_json::basic_json(const value_t value_type) -- create a JSON
value with the default value for a given type
@since version 1.0.0

@brief comparison operator for JSON types
Returns an ordering that is similar to Python:
- order: null < boolean < number < object < array < string < binary
- furthermore, each type is not smaller than itself
- discarded values are not comparable
- binary is represented as a b"" string in python and directly comparable to a
string; however, making a binary array directly comparable with a string would
be surprising behavior in a JSON file.
