The process of designing a neural network architecture. Building an effective neural network involves a series of steps, including defining the network structure, selecting activation functions, deciding on the number of layers, and more. Let’s break down the process:

1. Define the Problem: Clearly understand the problem you’re trying to solve. Is it a classification task, regression task, or something else? This understanding will guide the design of your network.

2. Choose an Architecture Type: Based on your problem, choose a suitable architecture type. For example:

  • Feedforward Neural Network (FNN): A basic architecture with input, hidden, and output layers.
  • Convolutional Neural Network (CNN): Suitable for image-based tasks.
  • Recurrent Neural Network (RNN): Used for sequential data like time series or text.
  • Transformer: Effective for sequence-to-sequence tasks like language translation.

3. Determine Input and Output Sizes: Define the size of your input data (e.g., image dimensions) and the number of output classes or regression targets.

4. Choose Activation Functions: Select appropriate activation functions for hidden layers. Common choices include ReLU (Rectified Linear Unit), sigmoid, and tanh. ReLU is often preferred due to its effectiveness in avoiding the vanishing gradient problem.

5. Decide on Layer Architecture: Determine the number of layers, units in each layer, and their connectivity. Deep networks with more layers tend to capture complex patterns, but be cautious of overfitting.

6. Include Regularization: Incorporate techniques like dropout or batch normalization to prevent overfitting and stabilize training.
