    If the dataset is balanced, we can use accuracy which is TP + TN /(TP+FP+TN+FN)
    If the dataset is unbalanced, we can use precision, recall and F1 score
    Precision=TP/TP+FP
    Recall=TP/TP+FN
    F1score= 2*precision*recall/(precision+recall)

    Where TP=True Positive
    FP=False Positive
    TN=True Negative
    FN=False Negative
