Web30 de mai. de 2024 · In Neural Network -Loss Function, We introduced loss functions, from concept to two main types – mean squared deviation function and cross-entropy loss function. However, deep neural networks (or DNNs) can use a variety of loss functions and activation functions. How to select these loss functions and activation functions? WebHowever, such activation functions are very hard to optimize due to large degeneracy in local minima [30], and the experimental results suggest that using sin as the activation function does not work well except for some very simple model, and that it can not compete against ReLU-based activation functions [34, 7, 25, 42] on standard tasks.

Web22 de jan. de 2024 · tf.keras.layers.Dense (1, activation="sigmoid") should be used for binary classification otherwise it is linear. Also, it might be better to choose an activation function here ( x = tf.keras.layers.Dense (100) (x) ) as well, i.e. activation = 'relu' . I suggest keeping it as default for now. Web14 de jun. de 2024 · Which would be the best pair of activation and loss function for these kinds of problems? The ones that I have considered are: Linear and L2 loss: L2 loss may lead to vanishing problems when the targets are small (like smaller than 0.1). Sigmoid and L1 loss: Should I use sigmoid for a regression problem?
