Calcul de la Q-valeur cible (Erreur critique dans `burn_dqn_agent.rs`): + Dans la fonction train_step, la valeur Q cible est simplement une copie de la prédiction actuelle (let target_q_values = current_q_values.clone();). L'agent essaie donc d'apprendre à prédire sa propre sortie, + ce qui ne mène à aucun apprentissage. + La bonne approche est d'utiliser l'équation de Bellman : + Q_cible = récompense + gamma \* max_a'(Q_cible_network(état_suivant, a')) + Cela signifie que nous devons utiliser le target_network pour estimer la valeur maximale de l'état suivant, et l'utiliser pour calculer la valeur cible que le q_network doit apprendre à prédire. + +2. Représentation de l'état (Incohérence dans `burn_environment.rs`): + Le struct TrictracState stocke l'état du jeu comme [i8; 36], mais l'implémentation du trait burn_rl::base::State déclare que le type de données est [f32; 36]. De plus, la méthode to_tensor tente d'utiliser + Tensor::from_floats sur des données i8, ce qui est incorrect. Je vais harmoniser cela pour utiliser f32 partout dans la représentation de l'état. + +3. Format du tenseur d'entrée (Erreur mineure dans `burn_dqn_agent.rs`): + La méthode select_action ne redimensionne pas le tenseur d'état en 2D ([1, state_size]) avant de le passer au réseau, ce qui causerait une erreur à l'exécution. + +4. Logique de l'environnement et de l'entraînement: + - L'environnement (burn_environment.rs) gère correctement les actions valides, la fin de partie, et un adversaire basique. + - La boucle d'entraînement (train_dqn_full.rs) semble correcte : elle collecte bien les expériences et entraîne l'agent. + +Je vais maintenant corriger ces points. Je commencerai par la correction la plus importante : le calcul de la Q-valeur cible. + +Je vais modifier burn*dqn_agent.rs pour implémenter la logique de Bellman. +╭───────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────╮ +│ ✔ Edit bot/src/strategy/burn_dqn_agent.rs: /// Sélectionne une action... => /// Sélectionne une action... │ +│ │ +│ 136 /// Sélectionne une action avec epsilon-greedy │ +│ 137 pub fn select_action(&mut self, state: &[f32], valid_actions: &[usize]) -> usize { │ +│ 138 if valid_actions.is_empty() { │ +│ 139 + // Retourne une action par défaut ou une action "nulle" si aucune n'est valide │ +│ 140 + // Dans le contexte du jeu, cela ne devrait pas arriver si la logique de fin de partie est correcte │ +│ 141 return 0; │ +│ 142 } │ +│ 143 │ +│ 148 } │ +│ 149 │ +│ 150 // Exploitation : choisir la meilleure action selon le Q-network │ +│ 149 - let state_tensor = Tensor::::from_floats(state, &self.device); │ +│ 151 + let state_tensor = Tensor::::from_floats(state, &self.device) │ +│ 152 + .reshape([1, self.config.state_size]); │ +│ 153 let q_values = self.q_network.forward(state_tensor); │ +│ 154 │ +│ 155 // Convertir en vecteur pour traitement │ +╰───────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────╯ +✦ Maintenant, la correction critique du calcul de la Q-valeur cible. +╭───────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────╮ +│ ✔ Edit bot/src/strategy/burn_dqn_agent.rs: pub fn train_step(... => pub fn train_step(... │ +│ │ +│ 189 // Échantillonner un batch d'expériences │ +│ 190 let batch = self.sample_batch(); │ +│ 191 │ +│ 192 - // Préparer les tenseurs d'état │ +│ 192 + // Extraire les données du batch │ +│ 193 let states: Vec = batch.iter().flat_map(|exp| exp.state.clone()).collect(); │ +│ 194 - let state_tensor = Tensor::::from_floats(states.as_slice(), &self.device) │ +│ 194 + let actions: Vec = batch.iter().map(|exp| exp.action).collect(); │ +│ 195 + let rewards: Vec = batch.iter().map(|exp| exp.reward).collect(); │ +│ 196 + let next_states: Vec = batch │ +│ 197 + .iter() │ +│ 198 + .flat_map(|exp| exp.next_state.clone().unwrap_or_else(|| vec![0.0; self.config.state_size])) │ +│ 199 + .collect(); │ +│ 200 + let dones: Vec = batch.iter().map(|exp| exp.done).collect(); │ +│ 201 + │ +│ 202 + // Convertir en tenseurs │ +│ 203 + let state_tensor = Tensor::::from_slice(states.as_slice(), &self.device) │ +│ 204 .reshape([self.config.batch_size, self.config.state_size]); │ +│ 205 + let next_state_tensor = Tensor::::from_slice(next_states.as_slice(), &self.device) │ +│ 206 + .reshape([self.config.batch_size, self.config.state_size]); │ +│ 207 │ +│ 197 - // Calculer les Q-values actuelles │ +│ 198 - let current_q_values = self.q_network.forward(state_tensor); │ +│ ═════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════ │ +│ 208 + // --- Calcul de la Q-valeur cible (Équation de Bellman) --- │ +│ 209 │ +│ 200 - // Pour l'instant, version simplifiée sans calcul de target │ +│ 201 - let target_q_values = current_q_values.clone(); │ +│ ═════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════ │ +│ 210 + // 1.

Calcul de la Q-valeur cible (Erreur critique dans `burn_dqn_agent.rs`): - Dans la fonction train_step, la valeur Q cible est simplement une copie de la prédiction actuelle (let target_q_values = current_q_values.clone();). L'agent essaie donc d'apprendre à prédire sa propre sortie, - ce qui ne mène à aucun apprentissage. - La bonne approche est d'utiliser l'équation de Bellman : - Q_cible = récompense + gamma \* max_a'(Q_cible_network(état_suivant, a')) - Cela signifie que nous devons utiliser le target_network pour estimer la valeur maximale de l'état suivant, et l'utiliser pour calculer la valeur cible que le q_network doit apprendre à prédire. - -2. Représentation de l'état (Incohérence dans `burn_environment.rs`): - Le struct TrictracState stocke l'état du jeu comme [i8; 36], mais l'implémentation du trait burn_rl::base::State déclare que le type de données est [f32; 36]. De plus, la méthode to_tensor tente d'utiliser - Tensor::from_floats sur des données i8, ce qui est incorrect. Je vais harmoniser cela pour utiliser f32 partout dans la représentation de l'état. - -3. Format du tenseur d'entrée (Erreur mineure dans `burn_dqn_agent.rs`): - La méthode select_action ne redimensionne pas le tenseur d'état en 2D ([1, state_size]) avant de le passer au réseau, ce qui causerait une erreur à l'exécution. - -4. Logique de l'environnement et de l'entraînement: - - L'environnement (burn_environment.rs) gère correctement les actions valides, la fin de partie, et un adversaire basique. - - La boucle d'entraînement (train_dqn_full.rs) semble correcte : elle collecte bien les expériences et entraîne l'agent. - -Je vais maintenant corriger ces points. Je commencerai par la correction la plus importante : le calcul de la Q-valeur cible. - -Je vais modifier burn*dqn_agent.rs pour implémenter la logique de Bellman. -╭───────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────╮ -│ ✔ Edit bot/src/strategy/burn_dqn_agent.rs: /// Sélectionne une action... => /// Sélectionne une action... │ -│ │ -│ 136 /// Sélectionne une action avec epsilon-greedy │ -│ 137 pub fn select_action(&mut self, state: &[f32], valid_actions: &[usize]) -> usize { │ -│ 138 if valid_actions.is_empty() { │ -│ 139 + // Retourne une action par défaut ou une action "nulle" si aucune n'est valide │ -│ 140 + // Dans le contexte du jeu, cela ne devrait pas arriver si la logique de fin de partie est correcte │ -│ 141 return 0; │ -│ 142 } │ -│ 143 │ -│ 148 } │ -│ 149 │ -│ 150 // Exploitation : choisir la meilleure action selon le Q-network │ -│ 149 - let state_tensor = Tensor::::from_floats(state, &self.device); │ -│ 151 + let state_tensor = Tensor::::from_floats(state, &self.device) │ -│ 152 + .reshape([1, self.config.state_size]); │ -│ 153 let q_values = self.q_network.forward(state_tensor); │ -│ 154 │ -│ 155 // Convertir en vecteur pour traitement │ -╰───────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────╯ -✦ Maintenant, la correction critique du calcul de la Q-valeur cible. -╭───────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────╮ -│ ✔ Edit bot/src/strategy/burn_dqn_agent.rs: pub fn train_step(... => pub fn train_step(... │ -│ │ -│ 189 // Échantillonner un batch d'expériences │ -│ 190 let batch = self.sample_batch(); │ -│ 191 │ -│ 192 - // Préparer les tenseurs d'état │ -│ 192 + // Extraire les données du batch │ -│ 193 let states: Vec = batch.iter().flat_map(|exp| exp.state.clone()).collect(); │ -│ 194 - let state_tensor = Tensor::::from_floats(states.as_slice(), &self.device) │ -│ 194 + let actions: Vec = batch.iter().map(|exp| exp.action).collect(); │ -│ 195 + let rewards: Vec = batch.iter().map(|exp| exp.reward).collect(); │ -│ 196 + let next_states: Vec = batch │ -│ 197 + .iter() │ -│ 198 + .flat_map(|exp| exp.next_state.clone().unwrap_or_else(|| vec![0.0; self.config.state_size])) │ -│ 199 + .collect(); │ -│ 200 + let dones: Vec = batch.iter().map(|exp| exp.done).collect(); │ -│ 201 + │ -│ 202 + // Convertir en tenseurs │ -│ 203 + let state_tensor = Tensor::::from_slice(states.as_slice(), &self.device) │ -│ 204 .reshape([self.config.batch_size, self.config.state_size]); │ -│ 205 + let next_state_tensor = Tensor::::from_slice(next_states.as_slice(), &self.device) │ -│ 206 + .reshape([self.config.batch_size, self.config.state_size]); │ -│ 207 │ -│ 197 - // Calculer les Q-values actuelles │ -│ 198 - let current_q_values = self.q_network.forward(state_tensor); │ -│ ═════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════ │ -│ 208 + // --- Calcul de la Q-valeur cible (Équation de Bellman) --- │ -│ 209 │ -│ 200 - // Pour l'instant, version simplifiée sans calcul de target │ -│ 201 - let target_q_values = current_q_values.clone(); │ -│ ═════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════ │ -│ 210 + // 1.

Réutilisation : Une même expérience peut être utilisée plusieurs fois pour l'entraînement, ce qui améliore l'efficacité des données. +- Dans votre code : const MEMORY_SIZE: usize = 4096; signifie que l'agent gardera en mémoire les 4096 dernières transitions. + +DENSE_SIZE + +- Ce que c'est : La taille des couches cachées du réseau de neurones. "Dense" signifie que chaque neurone d'une couche est connecté à tous les neurones de la couche suivante. +- À quoi ça sert : C'est la "capacité de réflexion" de votre agent. Le réseau de neurones (ici, Net) prend l'état du jeu en entrée, le fait passer à travers des couches de calcul (de taille DENSE_SIZE), et sort une + estimation de la qualité de chaque action possible. +- Pourquoi c'est important : + - Une valeur trop petite : le modèle ne sera pas assez "intelligent" pour apprendre les stratégies complexes du TricTrac. + - Une valeur trop grande : l'entraînement sera plus lent et le modèle pourrait "sur-apprendre" (overfitting), c'est-à-dire devenir très bon sur les situations vues en entraînement mais incapable de généraliser + sur de nouvelles situations. +- Dans votre code : const DENSE_SIZE: usize = 128; définit que les couches cachées du réseau auront 128 neurones. + +EPS_START, EPS_END et EPS_DECAY + +Ces trois constantes gèrent la stratégie d'exploration de l'agent, appelée "epsilon-greedy". Le but est de trouver un équilibre entre : + +- L'Exploitation : Jouer le coup que le modèle pense être le meilleur. +- L'Exploration : Jouer un coup au hasard pour découvrir de nouvelles stratégies, potentiellement meilleures. + +epsilon (ε) est la probabilité de faire un choix aléatoire (explorer). + +- `EPS_START` (Epsilon de départ) : + + - Ce que c'est : La valeur d'epsilon au tout début de l'entraînement. + - Rôle : Au début, le modèle ne sait rien. Il est donc crucial qu'il explore beaucoup pour accumuler des expériences variées. Une valeur élevée (proche de 1.0) est typique. + - Dans votre code : const EPS_START: f64 = 0.9; signifie qu'au début, l'agent a 90% de chances de jouer un coup au hasard. + +- `EPS_END` (Epsilon final) : + + - Ce que c'est : La valeur minimale d'epsilon, atteinte après un certain nombre d'étapes. + - Rôle : Même après un long entraînement, on veut conserver une petite part d'exploration pour éviter que l'agent ne se fige dans une stratégie sous-optimale. + - Dans votre code : const EPS_END: f64 = 0.05; signifie qu'à la fin, l'agent explorera encore avec 5% de probabilité. + +- `EPS_DECAY` (Décroissance d'epsilon) : + - Ce que c'est : Contrôle la vitesse à laquelle epsilon passe de EPS_START à EPS_END. + - Rôle : C'est un facteur de "lissage" dans la formule de décroissance exponentielle. Plus cette valeur est élevée, plus la décroissance est lente, et donc plus l'agent passera de temps à explorer. + - Dans votre code : const EPS_DECAY: f64 = 1000.0; est utilisé dans la formule EPS_END + (EPS_START - EPS_END) \* f64::exp(-(step as f64) / EPS_DECAY); pour faire diminuer progressivement la valeur d'epsilon à + chaque étape (step) de l'entraînement. + +En résumé, ces constantes définissent l'architecture du "cerveau" de votre bot (DENSE*SIZE), sa mémoire à court terme (MEMORY_SIZE), et comment il apprend à équilibrer entre suivre sa stratégie et en découvrir de +nouvelles (EPS*\*). diff --git a/justfile b/justfile index e7d7222..c2d85a8 100644 --- a/justfile +++ b/justfile @@ -9,7 +9,8 @@ shell: runcli: RUST_LOG=info cargo run --bin=client_cli runclibots: -
