[SNIPPET] I want dynamic learning rate adjustment based on validation loss improvement<|end|> <|assistant|>To implement dynamic learning rate adjustment based on validation loss improvement, we need to modify your `fit` method to include validation logic and adjust `alpha` accordingly. Here's how you can do it: python def fit(self,X,y,n_latent=5,n_epoch=20,lamda=0.1,val_split=0.1): """训练模型""" n_row,n_col = X.shape # Splitting data into training and validation sets val_size = int(n_row * val_split) X_train, X_val = X[val_size:], X[:val_size] y_train, y_val = y[val_size:], y[:val_size] self.U = np.random.normal(size=[n_col,n_latent]) self.V = np.random.normal(size=[n_latent,len(np.unique(y))]) opt_v = np.zeros_like(self.V) opt_u = np.zeros_like(self.U) sigma = .9 alpha_initial = .1 alpha_decay_factor = .9 best_val_loss = float('inf') patience_counter = 0 patience_threshold = n_epoch // 10 for epoch in range(n_epoch): # Training step here... # Update U, V using your preferred optimization method # Calculate validation loss after each epoch (simplified example) val_loss = self._calculate_loss(X_val, y_val) if val_loss < best_val_loss: best_val_loss = val_loss patience_counter = 0 else: patience_counter += 1 if patience_counter > patience_threshold: alpha_initial *= alpha_decay_factor print(f"Epoch {epoch+1}, Validation Loss {val_loss}, Learning Rate {alpha_initial}") You'll also need to implement `_calculate_loss` method if it doesn't exist yet. <|user|>@ calculate loss but not just mse i want cross entropy loss<|end|> <|assistant|>@ Sure! Here’s how you can modify your `_calculate_loss` method to use cross-entropy loss instead: python import numpy as np def _calculate_loss(self,X,y): """计算交叉熵损失""" predictions = np.dot(X @ self.U, self.V.T) probabilities = softmax(predictions.T).T # Cross-entropy loss calculation assuming y is one-hot encoded or converted appropriately log_likelihoods = -np.log(probabilities[np.arange(len(y)), y]) cross_entropy_loss = np.mean(log_likelihoods) return cross_entropy_loss def softmax(x): e_x = np.exp(x - np.max(x)) return e_x / e_x.sum(axis=1, keepdims=True) Make sure your labels `y` are one-hot encoded before using this loss function. <|user|>@ what if i want batch training with gradient clipping<|end|> <|assistant|>@ Sure! To implement batch training with gradient clipping, you’ll need to modify your `fit` method accordingly: python def fit(self,X,y,n_latent=5,n_epoch=20,lamda=0.1,val_split=0.1,batch_size=32,clip_value=5): """训练模型""" n_row,n_col = X.shape val_size = int(n_row * val_split) X_train, X_val = X[val_size:], X[:val_size] y_train, y_val = y[val_size:], y[:val_size] self.U = np.random.normal(size=[n_col,n_latent]) self.V = np.random.normal(size=[n_latent,len(np.unique(y))]) opt_v = np.zeros_like(self.V) opt_u = np.zeros_like(self.U) sigma = .9 alpha_initial = .1 best_val_loss = float('inf') patience_counter = 0 patience_threshold = n_epoch // 10 num_batches_per_epoch=len(X_train)//batch_size + int(len(X_train)%batch_size!=0) for epoch in range(n_epoch): indices=np.arange(len(X_train)) np.random.shuffle(indices) for batch_idx in range(num_batches_per_epoch): batch_indices=indices[batch_idx*batch_size:(batch_idx+1)*batch_size] X_batch=X_train[batch_indices] y_batch=y_train[batch_indices] # Forward pass (compute gradients here)... grad_U_batch, grad_V_batch=self._compute_gradients(X_batch,y_batch) # Gradient Clipping grad_U_batch=np.clip(grad_U_batch,-clip_value,clip_value) grad_V_batch=np.clip(grad_V_batch,-clip_value,clip_value) # Update parameters using gradients clipped values... self.U -= alpha_initial * grad_U_batch + lamda * self.U self
