Artificial Neural Networks (ANNs) are computational models inspired by the human brain. They consist of interconnected nodes called artificial neurons or units that are organized into layers. ANNs typically have an input layer, one or more hidden layers, and an output layer. The number of units in each layer depends on the specific task at hand.
Neurons in ANNs take input from the previous layer, perform computations, and produce an output. To introduce non-linearity and learn complex patterns, activation functions like sigmoid, tanh, or ReLU are applied to the output of each neuron. Additionally, each connection between neurons has an associated weight, which determines the strength of the connection. These weights are adjusted during the training phase to optimize the network’s performance.
During forward propagation, input data is fed into the network, and computations are performed layer by layer until the output layer is reached. Backpropagation is then carried out to train the network by adjusting the weights and biases. This process calculates the difference between the predicted output and the desired output and iteratively reduces the difference over multiple iterations.
Artificial Neural Networks have a wide range of applications across industries. They are used for tasks like image and speech recognition, natural language processing, financial analysis and prediction, medical diagnosis, and autonomous vehicles. ANNs can learn from data patterns and make informed predictions or decisions based on the learned information.
In conclusion, Artificial Neural Networks are powerful tools in machine learning, capable of learning and making predictions from complex data. Understanding their structure, principles, and various types allows us to leverage ANNs to solve a wide range of problems in different domains. As machine learning advances, the future of Artificial Neural Networks holds great potential for further advancements and applications.
