Logistic Regression using Single Layer Perceptron Neural Network (SLPNN) ... which is also called the logistic function. Neural Network Input. The input to the Neural network is the weighted sum of the inputs Xi: Activation function. The input is transformed using the activation function which generates values as probabilities from 0 to 1: The mathematical equation that describes. We will help you become good at Deep Learning. In five courses, you will learn the foundations of Deep Learning, understand how to build neural networks, and learn how to lead successful machine learning projects. You will learn about Convolutional networks, RNNs, LSTM, Adam, Dropout, BatchNorm, Xavier/He initialization, and more.
