Perceptron — Deep Learning BasicsAn upgrade to McCulloch-Pitts Neuron.Perceptron is a fundamental unit of the neural network which takes weighted inputs, process it and capable of performing binary classifications. In this post, we will discuss the working of the Perceptron Model. This is a follow-up blog post to my previous post on McCulloch-Pitts Neuron.In 1958 Frank Rosenblatt proposed the perceptron, a more generalized computational model than the McCulloch-Pitts Neuron. The important feature in the Rosenblatt proposed perceptron was the introduction of weights for the inputs. Later in 1960s Rosenblatt’s Model was refined and perfected by Minsky and Papert. Rosenblatt’s model is called as classical perceptron and the model analyzed by Minsky and Papert is called perceptron.Disclaimer: (...)

McCulloch Pitts Neuron — Deep Learning Building BlockThe fundamental block of deep learning is artificial neuron i.e.. it takes a weighted aggregate of inputs, applies a function and gives an output. The very first step towards the artificial neuron was taken by Warren McCulloch and Walter Pitts in 1943 inspired by neurobiology, created a model known as McCulloch-Pitts Neuron.Disclaimer: The content and the structure of this article is based on the deep learning lectures from One-Fourth Labs — Padhai.Motivation — Biological NeuronThe inspiration for the creation of an artificial neuron comes from the biological neuron.Fig — 1 Biological Neuron — Padhai Deep LearningIn a simplistic view, #neurons receive signals and produce a response. The general structure of a neuron is shown in the Fig-1. Dendrites (...)
