$($b$)$ A neural network is employed for a classification task where the target variable

takes $3$ classes, A$,$ B$,$ and C$.$ The network is trained using a softmax activation

output function and a categorical cross$-$entropy loss function. The table below

reports the outputs produced by the network and the associated labels of the

target variable for a sample of $4$ observations.

Compute the average loss and the classification accuracy for this sample.
