Feedforward Neural Networks
Feedforward neural networks are the simplest form of neural networks, with data flowing in one direction from input to output layer. They are commonly used in classification and regression tasks.
Recurrent Neural Networks
Recurrent neural networks have connections that form cycles, allowing them to analyze sequential data like time series. They are useful in language processing and speech recognition.
Convolutional Neural Networks
Convolutional neural networks are designed for image processing tasks, with specialized layers for feature extraction. They are widely used in computer vision applications.
Heatmaps
Heatmaps can show the activation levels of neurons in each layer, highlighting areas of high activity. They help identify important features in the data and understand the network's decision-making process.
Network Graphs
Network graphs display the interconnections between neurons, showing the network's architecture in a clear visual format. They help visualize the relationships between different layers and nodes.
Layer-wise Diagrams
Layer-wise diagrams break down the neural network into individual layers, detailing the specific functions of each layer. They provide a step-by-step visualization of how data is processed through the network.
Common Evaluation Metrics
