Perceptron Model
A Perceptron is a simple binary classifier used for linear regression. It is a linear model that predicts a single output based on a single input. The model takes the form of a hyperplane separating the input space into two regions: the positive class and the negative class.
Working Principle:
The Perceptron receives an input vector.
The input vector is transformed into a weighted sum of the input features.
The weighted sum is passed through a bias term to give the output.
The output is then applied to a activation function to determine the class of the input.
Assumptions:
Linearity: The data is linearly separable into two classes.
Linearity: The output function is linear.
Separability: There is a clear boundary between the two classes.
Advantages:
Simple and easy to implement.
Can be used for both classification and regression tasks.
Disadvantages:
Limited accuracy for complex non-linear problems.
Sensitive to noise and outliers.
Difficult to interpret the model's decision-making process.
Examples:
Imagine a hyperplane separating apples and oranges in a dataset.
A perceptron model can be used to classify emails as spam or not spam based on the presence of specific keywords.
A perceptron can be used to predict whether a customer will buy a product based on their demographics and purchase history
