Convolutional Layer 2D

This function block is used to create a 2D convolutional layer in a neural network. It allows users to configure settings for various convolution parameters, making it adaptable for different use cases.

📥 Inputs

This function block does not have any direct inputs.

📤 Outputs

This function block does not produce any outputs.

🕹️ Controls

Filter Size The number of filters to use in the convolution layer, which determines how many feature maps will be produced.

Kernel Size The dimensions of the convolution kernel, which should always be an odd number (e.g., 1, 3, 5).

Dilation Size The dilation rate for the convolutional layer. A dilation of -1 indicates default behavior. Dilation size can help reduce the parameter size of convolutional layers.

Activation Function A dropdown menu allowing you to choose an activation function to apply to the layer's output, with options like ReLU, sigmoid, and softmax among others.

🎨 Features

Flexible Configuration Users can adjust filter size, kernel size, dilation size, and activate functions according to specific model requirements.

Validation Checks The function block checks for valid parameters (e.g., kernel size must be odd) and provides error logging for invalid inputs.

📝 Usage Instructions

1. Configure Filter Size: Set the desired number of filters using the Filter Size input.

2. Set Kernel Size: Enter the kernel size using the Kernel Size input, ensuring it is an odd number.

3. Adjust Dilation Size: Specify the dilation rate if necessary or leave it as the default setting by entering -1.

4. Select Activation Function: Choose the desired activation function from the dropdown menu.

5. Integrate into Model: Use this block as part of a larger neural network configuration.

📊 Evaluation

Upon evaluation, this function block generates a configuration for a 2D convolutional layer according to the supplied parameters.

💡 Tips and Tricks

Choosing Kernel Size

Ensure that the kernel size is not only odd but moderate according to your input data dimensions. Larger kernels may lead to higher computation and loss of spatial resolution.

Using Different Activations

Experiment with different activation functions to find the one that best fits your model's performance and convergence speed.

Dilation Rate Effects

Using a dilation rate greater than 1 can help in expanding the receptive field of the convolutional filters without increasing the number of parameters.

🛠️ Troubleshooting

Kernel Size Error

If you encounter an error regarding kernel size, double-check that you are using an odd number as defined. Adjust the value as necessary.

Dilation Value Warning

If a negative dilation value is entered, an error will be logged. Ensure that dilation is set correctly to avoid misconfigurations.
