You need to debug your Stochastic Gradient Descent update for a classification of three bridge types.
Manually compute the model output for the feature vector $x=(1, 0, 0, 0, 0)$ and $W$ contains only zeros. The model is logistic regression, \textit{i.e.}, $\textrm{softmax}(Wx)$.
Remember:
\begin{equation}
\textrm{softmax}_i(s) = \frac{e^{s_i}}{\sum_k e^{s_k}}
\end{equation}
