Exported Tables

Exported Tables

The application can generate numerical tables after at least one epoch has been completed.

Use the Generate Table button in the sidebar.

The modal contains three tabs:

• Forward
• Backward
• Parameters

Each tab includes a Download CSV button.

Forward Table

The forward table records the values computed during the forward pass.

Typical columns for a 2,2,1 network:

epoch, x1, x2, y, z_h1, h1, z_h2, h2, z_y, y_hat, loss, class

Backward Table

The backward table records weight gradients by epoch.

Example columns:

epoch, grad_w1, grad_w2, grad_w3, grad_w4, grad_w5, grad_w6

The number of gradient columns depends on the number of connections in the network.

Parameter Evolution Table

The parameter table shows how weights, biases, activations, and average gradient magnitude evolve over time.

Example rows:

w1
w2
b1
h1
y_hat
grad_mean

Example columns:

Parameter, Initial, Epoch_1, Epoch_2, Epoch_3

File Names

The exported CSV files are:

• forward_pass.csv
• backward_gradients.csv
• parameter_evolution.csv
