![]() Neural networks have the ability to learn accurately with an example.To update the weight w i j Loss function ĭuring the 2000s it fell out of favour, but returned in the 2010s, benefitting from cheap, powerful GPU-based computing systems. In this method, neural networks are trained from errors generated to become self-sufficient and handle complex situations. In this article, the concept of Backpropagation of neural networks is explained using simple language for a reader to understand. The activation function of a neural network decides if the neuron should be activated/triggered or not based on the total sum. What is the activation function in a neural network? Neural networks are a series of learning algorithms or rules designed to identify the patterns.ĥ). It refers to the speed at which a neural network can learn new data by overriding the old data. The learning rate is defined in the context of optimization and minimizing the loss function of a neural network. What is the learning rate in neural networks? The objective of this algorithm is to create a training mechanism for neural networks to ensure that the network is trained to map the inputs to their appropriate outputs.ģ). What is the objective of the backpropagation algorithm? This is a mechanism used to train the neural network relating to the particular datasetĢ). Why do we need backpropagation in neural networks?
