Explanation
Supervised Learning in Neural Networks
Supervised learning is a training method where the network is provided with labeled input-output pairs. Among the given options, only the Multilayer Perceptron (MLP) uses supervised learning.
Multilayer Perceptron (MLP)
MLPs are feedforward neural networks that use supervised learning, typically trained with the backpropagation algorithm. They consist of an input layer, one or more hidden layers, and an output layer. During training, the network compares its output to the desired output and adjusts its weights to minimize the error.
Self-Organizing Feature Map (SOFM)
SOFMs, also known as Kohonen networks, use unsupervised learning. They are designed to discover patterns and relationships in input data without being provided with correct outputs. SOFMs organize similar data points together in a low-dimensional grid, typically 2D, preserving the topological structure of the input space.
Hopfield Network
Hopfield networks are a type of recurrent neural network that use unsupervised learning. They function as auto-associative memory for storage and recall of patterns. Hopfield networks are trained to converge to stable states, which represent stored patterns, and can be used for tasks like pattern completion and noise reduction.
Why Other Options Are Incorrect
Option B is incorrect because Self-organizing feature maps use unsupervised learning.
Option C is incorrect because Hopfield networks use unsupervised learning.
Option D is incorrect because it includes Self-organizing feature maps, which use unsupervised learning.
In conclusion, among the given options, only the Multilayer Perceptron (MLP) uses supervised learning, making A. (A) only the correct answer.
