Parameters

Let us dive deep into these parameters and understand them in detail:

  • max_iter (int, default=100): The first parameter that we will understand is the max_iter parameter. Its main task is to specify the maximum number of iterations also known as epochs which the perceptron will go through during training. If we increase the value then the algorithm will train longer. There is a chance that this can improve the performance.
  • tol (float, default=1e-3): The tol stands for tolerance. This tolerance can be thought of as a level required for the stopping criterion for training. It is generally helpful for preventing the overfitting.
  • eta0 (float, default=1.0): The eta0 parameter acts as the learning rate. This means that it has ability to determine the size of weight updates during every iteration.
  • fit_intercept (bool, default=True): When the fit_intercept parameter is set True which is the default value, the model includes the bias term in the decision function.
  • shuffle (bool, default=True): This one is self understanding by its name. When the shuffle parameter is True then the training data is shuffled at the beginning.
  • random_state (int or RandomState instance, default=None): It is used for seed initialization. It is eligible to ensure that there random weight initialization and data shuffling.
  • verbose (int, default=0): The verbose parameter is mainly used to control the verbosity level for progress messages during training. If there is a value of 0 then it denotes that no progress messages are printed.
  • warm_start (bool, default=False): When the warm_start parameter is set to True, it allows us to reuse the solution from a previous call.

Perceptron class in Sklearn

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.

Concepts Related to the 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....

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....

For our implementation part of using the perceptron for binary classification, we will be using the the Iris flower dataset. Our goal over here is to classify the Iris flowers into two categories: Setosa and Versicolor. For this purpose we will be using Python as our programming language and Scikit-Learn to implement and train the perceptron....
