WebSep 27, 2024 · The single layer Perceptron is the most basic neural network. It’s typically used for binary classification problems (1 or 0, “yes” or “no”). Some simple uses might be sentiment analysis (positive or negative response) or loan default prediction (“will default”, “will not default”). For both cases, the decision boundary would need to be linear. WebFeb 19, 2015 · Also, we calculate the sum of squared errors for a complete pass over the entire training dataset (in the batch learning mode) in contrast to the classic perceptron rule which updates the weights as new training samples arrive (analog to stochastic gradient descent -- online learning).
