Understanding Neural Networks
A neural network is a computational model inspired by the human brain. It consists of layers of interconnected nodes (neurons) that process input data and generate predictions. Neural networks are a fundamental component of modern , machine learning models ,Model architecture in tensorFlow inspired by the structure and function of the human brain. They consist of interconnected layers of nodes (neurons), where each connection has an associated weight that adjusts as the model learns. Neural networks excel at recognizing patterns and relationships in data, making them ideal for tasks such as image visualisation classification, Deep learning with tensorFlow, natural language processing, and speech recognition. Key types include feedforward networks, convolutional neural networks (CNNs), and recurrent neural networks (RNNs), each suited for different types of data and applications.Neural networks are computing systems inspired by the human brain’s structure and function. They consist of layers of interconnected nodes called neurons, where each connection carries a weight that adjusts during learning. Input data passes through these layers, with each neuron applying a mathematical transformation and activation function to detect patterns. Neural networks excel at solving complex problems like image recognition, natural language processing, and speech analysis by learning from data. Common types include feedforward networks, convolutional neural networks (CNNs) for images, and recurrent neural networks (RNNs) for sequential data. Their ability to model non-linear relationships makes them powerful tools in machine learning.
Model Architecture in TensorFlow
- Input Layer: Defines the shape and format of input data for the model.
- Hidden Layers: One or more layers of neurons that process inputs using activation functions (e.g., ReLU, sigmoid).
- Output Layer: Produces the final predictions; its size and activation depend on the task (e.g., softmax for classification).
- Sequential API: A linear stack of layers, ideal for simple feedforward models.
- Functional API: Allows for building complex models with shared layers, multiple inputs/outputs, and non-linear topologies.
- Custom Models with Subclassing: Enables full control by subclassing tf.keras.Model for advanced architectures.
- Layer Configuration: Each layer can be customized with parameters like number of units, Keras , activation functions, and initializers.
