 ## [Unreleased]

-## [1.1.1] - 2025-05-20
-
-### Internal
-
- Fix the vcpkg configuration in building the library.
- Fix the sample app to use the vcpkg configuration.
- Add predict_proba method to all Ld classifiers.
- Refactor the computeCPT method in the Node class with libtorch vectorized operations.
- Refactor the sample to use local discretization models.
-
-## [1.1.0] - 2025-04-27
-
-### Internal
-
- Add changes to .clang-format to adjust to vscode format style thanks to <https://clang-format-configurator.site/>
- Remove all the dependencies as git submodules and add them as vcpkg dependencies.
- Fix the dependencies versions for this specific BayesNet version.
-
-## [1.0.7] 2025-03-16
-
-### Added
-
- A new hyperparameter to the BoostAODE class, *alphablock*, to control the way &alpha; is computed, with the last model or with the ensmble built so far. Default value is *false*.
- A new hyperparameter to the SPODE class, *parent*, to set the root node of the model. If no value is set the root parameter of the constructor is used.
- A new hyperparameter to the TAN class, *parent*, to set the root node of the model. If not set the first feature is used as root.
- A new model named XSPODE, an optimized for speed averaged one dependence estimator.
- A new model named XSP2DE, an optimized for speed averaged two dependence estimator.
- A new model named XBAODE, an optimized for speed BoostAODE model.
- A new model named XBA2DE, an optimized for speed BoostA2DE model.
-
-### Internal
-
- Optimize ComputeCPT method in the Node class.
- Add methods getCount and getMaxCount to the CountingSemaphore class, returning the current count and the maximum count of threads respectively.
-
-### Changed
-
- Hyperparameter *maxTolerance* in the BoostAODE class is now in [1, 6] range (it was in [1, 4] range before).
-
-## [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

- 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.

-Bayesian Network Classifiers library
+Bayesian Network Classifiers using libtorch from scratch

-## Setup
+## Dependencies

-### Using the vcpkg library
-
-You can use the library with the vcpkg library manager. In your project you have to add the following files:
-
-#### vcpkg.json
-
-```json
-{
-  "name": "sample-project",
-  "version-string": "0.1.0",
-  "dependencies": [
-    "bayesnet"
-  ]
-}
-```
-
-#### vcpkg-configuration.json
-
-```json
-{
-  "registries": [
-    {
-      "kind": "git",
-      "repository": "https://github.com/rmontanana/vcpkg-stash",
-      "baseline": "393efa4e74e053b6f02c4ab03738c8fe796b28e5",
-      "packages": [
-        "folding",
-        "bayesnet",
-        "arff-files",
-        "fimdlp",
-        "libtorch-bin"
-      ]
-    }
-  ],
-  "default-registry": {
-    "kind": "git",
-    "repository": "https://github.com/microsoft/vcpkg",
-    "baseline": "760bfd0c8d7c89ec640aec4df89418b7c2745605"
-  }
-}
-```
-
-#### CMakeLists.txt
-
-You have to include the following lines in your `CMakeLists.txt` file:
-
-```cmake
-find_package(bayesnet CONFIG REQUIRED)
-
-add_executable(myapp main.cpp)
-
-target_link_libraries(myapp PRIVATE bayesnet::bayesnet)
-```
-
-After that, you can use the `vcpkg` command to install the dependencies:
+The only external dependency is [libtorch](https://pytorch.org/cppdocs/installing.html) which can be installed with the following commands:

 ```bash
-vcpkg install
+wget https://download.pytorch.org/libtorch/nightly/cpu/libtorch-shared-with-deps-latest.zip
+unzip libtorch-shared-with-deps-latest.zips
 ```

-**Note: In the `sample` folder you can find a sample application that uses the library. You can use it as a reference to create your own application.**
-
-## Playing with the library
-
-The dependencies are managed with [vcpkg](https://vcpkg.io/) and supported by a private vcpkg repository in [https://github.com/rmontanana/vcpkg-stash](https://github.com/rmontanana/vcpkg-stash).
+## Setup

 ### Getting the code

 ```bash
-git clone https://github.com/doctorado-ml/bayesnet
+git clone --recurse-submodules https://github.com/doctorado-ml/bayesnet
 ```

-Once you have the code, you can use the `make` command to build the project. The `Makefile` is used to manage the build process and it will automatically download and install the dependencies.
-
 ### Release

 ```bash
-make init # Install dependencies
-make release # Build the release version
-make buildr # compile and link the release version
+make release

+@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)
