Helpful examples of using Neural Network (multilayer perceptron) machine learning algorithms in scikit-learn.
The Neural Network algorithm is a versatile and powerful machine learning technique inspired by the structure and function of the human brain. It is used for a wide range of tasks, including classification, regression, and pattern recognition. A neural network consists of layers of interconnected nodes (neurons), where each connection has an associated weight. These layers include an input layer, one or more hidden layers, and an output layer.
Each neuron receives input, applies a linear transformation using the weights, adds a bias, and then passes the result through a non-linear activation function. This process allows the network to learn complex patterns and representations from the data. During training, the network adjusts the weights and biases through a process called backpropagation, which minimizes the difference between the predicted and actual outputs by propagating the error backward through the network and updating the weights using an optimization algorithm like gradient descent.
Neural networks can model complex and non-linear relationships, making them suitable for tasks such as image and speech recognition, natural language processing, and time series forecasting. While neural networks are powerful, they require large amounts of data and computational resources, and they can be prone to overfitting if not properly regularized.
