WebbThe softmax function is a function that turns a vector of K real values into a vector of K real values that sum to 1. The input values can be positive, negative, zero, or greater than one, but the softmax transforms them into values between 0 and 1, so that they can be interpreted as probabilities. If one of the inputs is small or negative, the ... Webb28 dec. 2024 · Sigmoid Function. The sigmoid function is one of the most used activation functions in machine learning and deep learning. It can be used in the hidden layers, … Webbrelu function. tf.keras.activations.relu(x, alpha=0.0, max_value=None, threshold=0.0) Applies the rectified linear unit activation function. With default values, this returns the standard ReLU activation: max (x, 0), the element-wise maximum of 0 and the input tensor. Modifying default parameters allows you to use non-zero thresholds, change ... can lithium cause kidney damage
