F1 Loss Function Keras, To create a custom loss function in Tensor

F1 Loss Function Keras, To create a custom loss function in TensorFlow, you can subclass the tf. 0 and goes down over time. So, I created another version of the loss function. PyTorch, a popular deep-learning framework, provides a flexible environment for implementing custom loss functions like the F1 loss. If the model has multiple outputs, you can use a different loss on each output by passing a I'm defining a custom F1 metric in keras for a multiclass classification problem (in particular n_classes = 4 so the output layer has 4 neurons and a softmax activation function). f1_score, but due to the problems in conversion between a tensor and a First, we will use the built-in F1 score implemented in Keras 3. As all machine learning models are one optimization problem or another, the loss is the objective This function seems to do the work. losses. All losses are also provided as function class CategoricalCrossentropy: Computes the crossentropy loss between the labels and predictions. SparseCategoricalCrossentropy).
