题目介绍：

In the preceding segment of this practice, you coded multi-class logistic regression to identify handwritten digits. However, due to its inherent linearity, logistic regression is restricted in forming more intricate hypotheses.

Within this section of the assignment, you will code a neural network model designed to classify handwritten digits using the established training dataset. The model's architecture enables it to capture complex patterns through non-li
