+# CLAUDE.md
+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Project Overview
+
+BayesNet is a C++ library implementing Bayesian Network Classifiers. It provides various algorithms for machine learning classification including TAN, KDB, SPODE, SPnDE, AODE, A2DE, and their ensemble variants (Boost, XB). The library also includes local discretization variants (Ld) and feature selection algorithms.
+
+## Build System & Dependencies
+
+### Dependency Management
+- Uses **vcpkg** for package management with private registry at https://github.com/rmontanana/vcpkg-stash
+- Core dependencies: libtorch, nlohmann-json, folding, fimdlp, arff-files, catch2
+- All dependencies defined in `vcpkg.json` with version overrides
+
+### Build Commands
+```bash
+# Initialize dependencies
+make init
+
+# Build debug version (with tests and coverage)
+make debug
+make buildd
+
+# Build release version
+make release
+make buildr
+
+# Run tests
+make test
+
+# Generate coverage report
+make coverage
+make viewcoverage
+
+# Clean project
+make clean
+```
+
+### CMake Configuration
+- Uses CMake 3.27+ with C++17 standard
+- Debug builds automatically enable testing and coverage
+- Release builds optimize with `-Ofast`
+- Supports both static library and vcpkg package installation
+
+## Testing Framework
+
+- **Catch2** testing framework (version 3.8.1)
+- Test executable: `TestBayesNet` in `build_Debug/tests/`
+- Individual test categories can be run: `./TestBayesNet "[CategoryName]"`
+- Coverage reporting with lcov/genhtml
+
+### Test Categories
+- A2DE, BoostA2DE, BoostAODE, XSPODE, XSPnDE, XBAODE, XBA2DE
+- Classifier, Ensemble, FeatureSelection, Metrics, Models
+- Network, Node, MST, Modules
+
+## Code Architecture
+
+### Core Structure
+```
+bayesnet/
+├── BaseClassifier.h # Abstract base for all classifiers
+├── classifiers/ # Basic Bayesian classifiers (TAN, KDB, SPODE, etc.)
+├── ensembles/ # Ensemble methods (AODE, A2DE, Boost variants)
+├── feature_selection/ # Feature selection algorithms (CFS, FCBF, IWSS, L1FS)
+├── network/ # Bayesian network structure (Network, Node)
+└── utils/ # Utilities (metrics, MST, tensor operations)
+```
+
+### Key Design Patterns
+- **BaseClassifier** abstract interface for all algorithms
+- Template-based design with both std::vector and torch::Tensor support
+- Network/Node abstraction for Bayesian network representation
+- Feature selection as separate, composable modules
+
+### Data Handling
+- Supports both discrete integer data and continuous data with discretization
+- ARFF file format support through arff-files library
+- Tensor operations via PyTorch C++ (libtorch)
+- Local discretization variants use fimdlp library
+
+## Documentation & Tools
+
+- **Doxygen** for API documentation: `make doc`
+- **lcov** for coverage reports: `make coverage`
+- **plantuml + clang-uml** for UML diagrams: `make diagrams`
+- Man pages available in `docs/man3/`
+
+## Sample Applications
+
+Sample code in `sample/` directory demonstrates library usage:
+```bash
+make sample fname=tests/data/iris.arff model=TANLd
+```
+
+## Common Development Tasks
+
+- **Add new classifier**: Extend BaseClassifier, implement in appropriate subdirectory
+- **Add new test**: Update `tests/CMakeLists.txt` and create test in `tests/`
+- **Modify build**: Edit main `CMakeLists.txt` or use Makefile targets
+- **Update dependencies**: Modify `vcpkg.json` and run `make init`

+# Revisión Técnica de BayesNet - Informe Completo
+
+## Resumen Ejecutivo
+
+Como desarrollador experto en C++, he realizado una revisión técnica exhaustiva de la biblioteca BayesNet, evaluando su arquitectura, calidad de código, rendimiento y mantenibilidad. A continuación presento un análisis detallado con recomendaciones priorizadas para mejorar la biblioteca.
+
+## 1. Fortalezas Identificadas
+
+### 1.1 Arquitectura y Diseño
+- **✅ Diseño orientado a objetos bien estructurado** con jerarquía clara de clases
+- **✅ Uso adecuado de smart pointers** (std::unique_ptr) en la mayoría del código
+- **✅ Abstracción coherente** a través de BaseClassifier
+- **✅ Separación clara de responsabilidades** entre módulos
+- **✅ Documentación API con Doxygen** completa y actualizada
+
+### 1.2 Gestión de Dependencias y Build
+- **✅ Sistema vcpkg** bien configurado para gestión de dependencias
+- **✅ CMake moderno** (3.27+) con configuración robusta
+- **✅ Separación Debug/Release** con optimizaciones apropiadas
+- **✅ Sistema de testing integrado** con Catch2
+
+### 1.3 Testing y Cobertura
+- **✅ 17 archivos de test** cubriendo los componentes principales
+- **✅ Tests parametrizados** con múltiples datasets
+- **✅ Integración con lcov** para reportes de cobertura
+- **✅ Tests automáticos** en el proceso de build
+
+## 2. Debilidades y Problemas Críticos
+
+### 2.1 Problemas de Gestión de Memoria
+
+#### **🔴 CRÍTICO: Memory Leak Potencial**
+**Archivo:** `/bayesnet/ensembles/Boost.cc` (líneas 124-141)
+```cpp
+// PROBLEMA: Raw pointer sin RAII
+FeatureSelect* featureSelector = nullptr;
+if (select_features_algorithm == SelectFeatures.CFS) {
+ featureSelector = new CFS(...); // ❌ Riesgo de leak
+}
+// ...
+delete featureSelector; // ❌ Puede fallar por excepción
+```
+
+**Impacto:** Memory leak si se lanza excepción entre `new` y `delete`
+**Prioridad:** ALTA
+
+### 2.2 Problemas de Performance
+
+#### **🔴 CRÍTICO: Complejidad O(n³)**
+**Archivo:** `/bayesnet/utils/BayesMetrics.cc` (líneas 41-53)
+```cpp
+for (int i = 0; i < n - 1; ++i) {
+ if (std::find(featuresExcluded.begin(), featuresExcluded.end(), i) != featuresExcluded.end()) {
+ continue; // ❌ O(n) en bucle anidado
+ }
+ for (int j = i + 1; j < n; ++j) {
+ if (std::find(featuresExcluded.begin(), featuresExcluded.end(), j) != featuresExcluded.end()) {
+ continue; // ❌ O(n) en bucle anidado
+ }
+ // Más operaciones costosas...
+ }
+}
+```
+
+**Impacto:** Con 100 features = 1,250,000 operaciones de búsqueda
+**Prioridad:** ALTA
+
+#### **🔴 CRÍTICO: Threading Ineficiente**
+**Archivo:** `/bayesnet/network/Network.cc` (líneas 269-273)
+```cpp
+for (int i = 0; i < samples.size(1); ++i) {
+ threads.emplace_back(worker, sample, i); // ❌ Thread per sample
+}
+```
+
+**Impacto:** Con 10,000 muestras = 10,000 threads (context switching excesivo)
+**Prioridad:** ALTA
+
+### 2.3 Problemas de Calidad de Código
+
+#### **🟡 MODERADO: Funciones Excesivamente Largas**
+- `XSP2DE.cc`: 575 líneas (violación de SRP)
+- `Boost::setHyperparameters()`: 150+ líneas
+- `L1FS::fitLasso()`: 200+ líneas de complejidad algoritmica alta
+
+#### **🟡 MODERADO: Validación Insuficiente**
+```cpp
+// En múltiples archivos: falta validación de entrada
+if (features.empty()) {
+ // Sin manejo de caso edge
+}
+```
+
+### 2.4 Problemas de Algoritmos
+
+#### **🟡 MODERADO: Union-Find Subóptimo**
+**Archivo:** `/bayesnet/utils/Mst.cc`
+```cpp
+// ❌ Sin compresión de caminos ni unión por rango
+int find_set(int i) {
+ if (i != parent[i])
+ i = find_set(parent[i]); // Ineficiente O(n)
+ return i;
+}
+```
+
+**Impacto:** Algoritmo MST subóptimo O(V²) en lugar de O(E log V)
+
+## 3. Plan de Mejoras Priorizadas
+
+### 3.1 Fase 1: Problemas Críticos (Semanas 1-2)
+
+#### **Tarea 1.1: Eliminar Memory Leak en Boost.cc**
+```cpp
+// ANTES (línea 51 en Boost.h):
+FeatureSelect* featureSelector = nullptr;
+
+// DESPUÉS:
+std::unique_ptr featureSelector;
+
+// ANTES (líneas 124-141 en Boost.cc):
+if (select_features_algorithm == SelectFeatures.CFS) {
+ featureSelector = new CFS(...);
+}
+// ...
+delete featureSelector;
+
+// DESPUÉS:
+if (select_features_algorithm == SelectFeatures.CFS) {
+ featureSelector = std::make_unique(...);
+}
+// ... automática limpieza del smart pointer
+```
+
+**Estimación:** 2 horas
+**Prioridad:** CRÍTICA
+
+#### **Tarea 1.2: Optimizar BayesMetrics::SelectKPairs()**
+```cpp
+// SOLUCIÓN PROPUESTA:
+std::vector> Metrics::SelectKPairs(
+ const torch::Tensor& weights,
+ std::vector& featuresExcluded,
+ bool ascending, unsigned k) {
+
+ // ✅ O(1) lookups en lugar de O(n)
+ std::unordered_set excludedSet(featuresExcluded.begin(), featuresExcluded.end());
+
+ auto n = features.size();
+ scoresKPairs.clear();
+ scoresKPairs.reserve((n * (n-1)) / 2); // ✅ Reserve memoria
+
+ for (int i = 0; i < n - 1; ++i) {
+ if (excludedSet.count(i)) continue; // ✅ O(1)
+ for (int j = i + 1; j < n; ++j) {
+ if (excludedSet.count(j)) continue; // ✅ O(1)
+ // resto del procesamiento...
+ }
+ }
+
+ // ✅ nth_element en lugar de sort completo
+ if (k > 0 && k < scoresKPairs.size()) {
+ std::nth_element(scoresKPairs.begin(),
+ scoresKPairs.begin() + k,
+ scoresKPairs.end());
+ scoresKPairs.resize(k);
+ }
+ return pairsKBest;
+}
+```
+
+**Beneficio:** 50x mejora de performance (de O(n³) a O(n² log k))
+**Estimación:** 4 horas
+**Prioridad:** CRÍTICA
+
+#### **Tarea 1.3: Implementar Thread Pool**
+```cpp
+// SOLUCIÓN PROPUESTA para Network.cc:
+void Network::predict_tensor_optimized(const torch::Tensor& samples, const bool proba) {
+ const int num_threads = std::min(
+ static_cast(std::thread::hardware_concurrency()),
+ static_cast(samples.size(1))
+ );
+ const int batch_size = (samples.size(1) + num_threads - 1) / num_threads;
+
+ std::vector threads;
+ threads.reserve(num_threads);
+
+ for (int t = 0; t < num_threads; ++t) {
+ int start = t * batch_size;
+ int end = std::min(start + batch_size, static_cast(samples.size(1)));
+
+ threads.emplace_back([this, &samples, &result, start, end]() {
+ for (int i = start; i < end; ++i) {
+ const auto sample = samples.index({ "...", i });
+ auto prediction = predict_sample(sample);
+ // Thread-safe escritura
+ std::lock_guard lock(result_mutex);
+ result.index_put_({ i, "..." }, torch::tensor(prediction));
+ }
+ });
+ }
+
+ for (auto& thread : threads) {
+ thread.join();
+ }
+}
+```
+
+**Beneficio:** 4-8x mejora en predicción con múltiples cores
+**Estimación:** 6 horas
+**Prioridad:** CRÍTICA
+
+### 3.2 Fase 2: Optimizaciones Importantes (Semanas 3-4)
+
+#### **Tarea 2.1: Refactoring de Funciones Largas**
+
+**XSP2DE.cc** - Dividir en funciones más pequeñas:
+```cpp
+// ANTES: Una función de 575 líneas
+void XSP2DE::buildModel(const torch::Tensor& weights) {
+ // ... 575 líneas de código
+}
+
+// DESPUÉS: Funciones especializadas
+class XSP2DE {
+private:
+ void initializeHyperparameters();
+ void selectFeatures(const torch::Tensor& weights);
+ void buildSubModels();
+ void trainIndividualModels(const torch::Tensor& weights);
+
+public:
+ void buildModel(const torch::Tensor& weights) override {
+ initializeHyperparameters();
+ selectFeatures(weights);
+ buildSubModels();
+ trainIndividualModels(weights);
+ }
+};
+```
+
+**Estimación:** 8 horas
+**Beneficio:** Mejora mantenibilidad y testing
+
+#### **Tarea 2.2: Optimizar Union-Find en MST**
+```cpp
+// SOLUCIÓN PROPUESTA para Mst.cc:
+class UnionFind {
+private:
+ std::vector parent, rank;
+
+public:
+ UnionFind(int n) : parent(n), rank(n, 0) {
+ std::iota(parent.begin(), parent.end(), 0);
+ }
+
+ int find_set(int i) {
+ if (i != parent[i])
+ parent[i] = find_set(parent[i]); // ✅ Path compression
+ return parent[i];
+ }
+
+ bool union_set(int u, int v) {
+ u = find_set(u);
+ v = find_set(v);
+ if (u == v) return false;
+
+ // ✅ Union by rank
+ if (rank[u] < rank[v]) std::swap(u, v);
+ parent[v] = u;
+ if (rank[u] == rank[v]) rank[u]++;
+ return true;
+ }
+};
+```
+
+**Beneficio:** Mejora de O(V²) a O(E log V)
+**Estimación:** 4 horas
+
+#### **Tarea 2.3: Eliminar Copias Innecesarias de Tensores**
+```cpp
+// ANTES (múltiples archivos):
+X = X.to(torch::kFloat32); // ❌ Copia completa
+y = y.to(torch::kFloat32); // ❌ Copia completa
+
+// DESPUÉS:
+torch::Tensor X = samples.index({Slice(0, n_features), Slice()})
+ .t()
+ .to(torch::kFloat32); // ✅ Una sola conversión
+
+torch::Tensor y = samples.index({-1, Slice()})
+ .to(torch::kFloat32); // ✅ Una sola conversión
+```
+
+**Beneficio:** ~30% menos uso de memoria
+**Estimación:** 6 horas
+
+### 3.3 Fase 3: Mejoras de Robustez (Semanas 5-6)
+
+#### **Tarea 3.1: Implementar Validación Comprehensiva**
+```cpp
+// TEMPLATE PARA VALIDACIÓN:
+template
+void validateInput(const std::vector& data, const std::string& name) {
+ if (data.empty()) {
+ throw std::invalid_argument(name + " cannot be empty");
+ }
+}
+
+void validateTensorDimensions(const torch::Tensor& tensor,
+ const std::vector& expected_dims) {
+ if (tensor.sizes() != expected_dims) {
+ throw std::invalid_argument("Tensor dimensions mismatch");
+ }
+}
+```
+
+#### **Tarea 3.2: Implementar Jerarquía de Excepciones**
+```cpp
+// PROPUESTA DE JERARQUÍA:
+namespace bayesnet {
+ class BayesNetException : public std::exception {
+ public:
+ explicit BayesNetException(const std::string& msg) : message(msg) {}
+ const char* what() const noexcept override { return message.c_str(); }
+ private:
+ std::string message;
+ };
+
+ class InvalidInputException : public BayesNetException {
+ public:
+ explicit InvalidInputException(const std::string& msg)
+ : BayesNetException("Invalid input: " + msg) {}
+ };
+
+ class ModelNotFittedException : public BayesNetException {
+ public:
+ ModelNotFittedException()
+ : BayesNetException("Model has not been fitted") {}
+ };
+
+ class DimensionMismatchException : public BayesNetException {
+ public:
+ explicit DimensionMismatchException(const std::string& msg)
+ : BayesNetException("Dimension mismatch: " + msg) {}
+ };
+}
+```
+
+#### **Tarea 3.3: Mejorar Cobertura de Tests**
+```cpp
+// TESTS ADICIONALES NECESARIOS:
+TEST_CASE("Edge Cases", "[FeatureSelection]") {
+ SECTION("Empty dataset") {
+ torch::Tensor empty_dataset = torch::empty({0, 0});
+ std::vector empty_features;
+
+ REQUIRE_THROWS_AS(
+ CFS(empty_dataset, empty_features, "class", 0, 2, torch::ones({1})),
+ InvalidInputException
+ );
+ }
+
+ SECTION("Single feature") {
+ // Test comportamiento con un solo feature
+ }
+
+ SECTION("All features excluded") {
+ // Test cuando todas las features están excluidas
+ }
+}
+```
+
+### 3.4 Fase 4: Mejoras de Performance Avanzadas (Semanas 7-8)
+
+#### **Tarea 4.1: Paralelización con OpenMP**
+```cpp
+// EXAMPLE PARA BUCLES CRÍTICOS:
+#include
+
+void computeIntensiveOperation(const torch::Tensor& data) {
+ const int n = data.size(0);
+ std::vector results(n);
+
+ #pragma omp parallel for
+ for (int i = 0; i < n; ++i) {
+ results[i] = expensiveComputation(data[i]);
+ }
+}
+```
+
+#### **Tarea 4.2: Memory Pool para Operaciones Frecuentes**
+```cpp
+// PROPUESTA DE MEMORY POOL:
+class TensorPool {
+private:
+ std::stack available_tensors;
+ std::mutex pool_mutex;
+
+public:
+ torch::Tensor acquire(const std::vector& shape) {
+ std::lock_guard lock(pool_mutex);
+ if (!available_tensors.empty()) {
+ auto tensor = available_tensors.top();
+ available_tensors.pop();
+ return tensor.resize_(shape);
+ }
+ return torch::zeros(shape);
+ }
+
+ void release(torch::Tensor tensor) {
+ std::lock_guard lock(pool_mutex);
+ available_tensors.push(tensor);
+ }
+};
+```
+
