Single-layer Perceptron
A single-layer perceptron is a type of neural network that consists of a single layer of output nodes that are connected to a set of input nodes, where each input node is connected to each output node with a weight. The single-layer perceptron is typically used for binary classification problems.
Here's an example of how to implement a single-layer perceptron in Python using the scikit-learn library:
from sklearn.linear_model import Perceptron
# Define the input features and target labels
X = [[0, 0], [0, 1], [1, 0], [1, 1]]
y = [0, 0, 0, 1]
# Create a Perceptron object and fit the model to the data
clf = Perceptron(random_state=0)
clf.fit(X, y)
# Predict the output for a new set of input features
new_X = [[0, 0], [0, 1], [1, 0], [1, 1]]
predictions = clf.predict(new_X)
# Print the predicted outputs
print(predictions) # Output: [0 0 0 1]
In this example, we first define the input features (X
) and target labels (y
) for a binary classification problem. We then create a Perceptron
object from the scikit-learn library and fit the model to the data using the fit
method.
After fitting the model, we can use it to predict the output for a new set of input features (new_X
) using the predict
method. Finally, we print the predicted outputs to the console.
Note that this is a basic example of how to implement a single-layer perceptron using scikit-learn, and there are many ways to improve the performance of the model, such as tuning hyperparameters, using more sophisticated activation functions, or adding additional layers to the network.
