Artificial Neural Networks (ANNs)
Issue #69 | Dec 07, 2024
Hello!!
Welcome to the new edition of Business Analytics Review!
Today, we’re exploring a fascinating concept in machine learning: Artificial Neural Networks (ANNs). These are a subset of machine learning inspired by the structure and function of the human brain. They are composed of interconnected nodes, or neurons, organized into layers. These networks are designed to learn and make decisions based on input data.
By mimicking the human brain's learning mechanisms, ANNs can uncover patterns, make predictions, and adapt to new data with remarkable accuracy. Their versatility and scalability make them essential tools in areas like healthcare, finance, robotics, and more. As advancements in computing power, data availability, and algorithmic innovation continue, ANNs will undoubtedly play a pivotal role in shaping the future of technology and transforming industries worldwide.
Basic Structure of an ANN
Input Layer: Receives input data and passes it to the hidden layers
Hidden Layers: Process the input data and extract features
Output Layer: Produces the final output, which can be a classification, regression, or other prediction
How ANNs Work:
Input: Data is fed into the input layer
Forward Propagation: Data flows through the network from the input layer to the output layer, producing predictions
Loss Calculation: The loss function calculates the error in the predictions
Backward Propagation: Using techniques like backpropagation, the model adjusts weights and biases based on the error to improve predictions
Iterative Learning: Through multiple iterations (epochs), the model refines its parameters to improve accuracy
Output: The final output is generated by the output layer
Applications of ANNs:
Image and Speech Recognition: Identifying objects and understanding spoken language
Natural Language Processing: Analyzing and generating human language
Medical Diagnosis: Assisting in disease diagnosis and treatment planning
Financial Forecasting: Predicting stock prices and market trends
Autonomous Vehicles: Enabling self-driving cars to perceive and navigate the environment
