Create a table to store the weights and biases for each connection:
Suppose we want to build a neural network that predicts the output of a simple XOR (exclusive OR) function. The XOR function takes two binary inputs and produces an output of 1 if the inputs are different and 0 if they are the same. build neural network with ms excel full
| Input 1 | Input 2 | Output | | --- | --- | --- | | 0 | 0 | 0 | | 0 | 1 | 1 | | 1 | 0 | 1 | | 1 | 1 | 0 | Create a table to store the weights and
Calculate the error between the predicted output and the actual output: While MS Excel is not the most efficient
| Connection | Weight | Bias | | --- | --- | --- | | Input 1 -> Hidden 1 | 0.5 | 0.2 | | Input 1 -> Hidden 2 | 0.3 | 0.1 | | Input 2 -> Hidden 1 | 0.2 | 0.4 | | Input 2 -> Hidden 2 | 0.6 | 0.3 | | Hidden 1 -> Output | 0.8 | 0.5 | | Hidden 2 -> Output | 0.4 | 0.6 |
Building a neural network with MS Excel is a feasible and educational project that can help beginners understand the basics of neural networks. While MS Excel is not the most efficient tool for large-scale neural network training, it can be used for rapid prototyping and testing of neural network architectures.
Update the weights and biases using the gradients and a learning rate:
