Understanding Perceptron

A perceptron is a kind of artificial neuron or node that is utilized in neural networks and machine learning. It is an essential component of more intricate models.

  • It is popular for being the initial point for supervised learning algorithms.
  • Considered to lay the foundation for complex neural networks.
  • It is very useful for binary classification.
  • It is inspired by the biological neuron. We can assume that it acts as a simplified version of the biological neuron.
  • One thing that must be known is that the real purpose behind using a perceptron is to collect the input features and then calculate a weighted sum of all these features. Finally, it makes a binary decision based on the result and hence it is useful in binary classification problems.

Machine learning is a prominent technology in this modern world and as years go by it is growing immensely. There are several components involved in Machine Learning that make it evolve and solve various problems and one such crucial component that exists is the Perceptron. In this article, we will be learning about what a perceptron is, the history of perceptron, and how one can use the same with the help of the Scikit-Learn, library which is arguably one of the most popular machine learning libraries in Python.

Frank Rosenblatt led the development of perceptron in the late 1950s. It is said that this was one of the earliest supervised learning algorithms that did exist. The primary reason behind developing a perceptron was to classify the given data into two categories. So we are confident enough to claim that a perceptron is a type of artificial neural network, that is actually based on real-life biological neurons which in turn makes it a binary classifier.

Mathematical Foundation

Binary Classification: Binary Classification is a supervised learning algorithm whose primary job is to classify the data into two separate classes. Perceptron has an important role to play in binary classification as it is used to classify the data into one of the two classes.Weights and Bias: The main function of the perceptron is to give weights to every input parameter present in the data and then adding them with a bias unit. In order to get the optimal results, the weights and bias are adjusted during the training part.Activation Function: The main role of the activation function is to determine whether a neuron should be activated or not based on certain conditions. The perceptron executes a simple activation function. Based on certain conditions such as if the weighted sum of inputs and the bias is more than or equal to zero, then one of the two classes is predicted else the other class. Learning Rate: Learning Rate has the ability to control the weights and it represents how quickly the neural network understands and updates the concepts that it has previously learned....
