Neural Networks are a fundamental building block of Deep Learning. These networks are inspired by the human brain’s functioning and consist of neuron connections capable of learning and modeling patterns in data. Here’s the theory behind neural networks:
Neural Networks:
Neurons: Neurons in neural networks are the basic computational units. Each neuron has weights that represent its importance in making decisions about input data and an activation function that determines the neuron’s output based on weights and input data.
Layers: Neural networks are usually organized into layers. The input layer receives input data, hidden layers (if present) perform computations, and the output layer generates results. Deeper networks have multiple hidden layers.
Weights: Weights are parameters that are learned during network training. They determine how input data is weighted and contribute to neuron decisions.
Activation Functions: Activation functions of neurons define their outputs based on weights and inputs. Some common activation functions include sigmoid (restricting output values between 0 and 1), ReLU (Rectified Linear Unit, a non-linear function allowing fast learning), and tanh (hyperbolic tangent).
Principle of Neural Network Operation:
Forward Pass: Input data goes through weight connections into network neurons.
Weighted Summation: For each neuron, a weighted sum of inputs is calculated.
Activation: This weighted sum undergoes an activation function, determining the neuron’s output. Activation functions help introduce non-linearity into the network.
Feedback: After computing the output, it’s compared to target values (in supervised learning), and the error is used to update weights.
Learning: Training a neural network involves iteratively adjusting weights to minimize the error between predicted and actual values.
Neural networks have a wide range of applications, including:
Image Recognition: Convolutional Neural Networks (CNNs) are used for object recognition, classification, and tasks like those in autonomous vehicles and medical diagnostics.
Speech Processing: Recurrent Neural Networks (RNNs) are employed in speech recognition, speech synthesis, language translation, and more.
Natural Language Processing (NLP): Deep neural networks are used for text analysis, chatbots, and information extraction from text.
Autonomous Vehicles: Neural networks assist vehicles in recognizing obstacles, navigating, and making decisions.
Biomedical Applications: They are used for disease diagnosis based on medical images, genetic data, and biological data analysis.
Financial Predictions: Neural networks are applied for market trend prediction, fraud detection, and investment portfolio optimization.
Generative Models: Deep networks can generate new content, such as artificial images, music, and text.
Deep neural networks are powerful tools for data analysis and solving various tasks, and their performance continues to improve with the increasing availability of data and technological advancements.
