Q1. How do you train semi supervised machine learning models?
Ans. 
Train semi supervised machine learning models by using a combination of labeled and unlabeled data.
• Start by training a model on a small amount of labeled data

• Use the trained model to make predictions on the unlabeled data

• Incorporate the predictions into the training set and retrain the model

• Repeat the process until the model reaches a satisfactory level of performance

Q13. How do you calculate precision & recall for n x n confusion matrix?
Ans. 
Precision and recall can be calculated using values from a confusion matrix.
• Precision = TP / (TP + FP)

• Recall = TP / (TP + FN)

• Where TP = True Positive, FP = False Positive, FN = False Negative

• For an n x n confusion matrix, sum the values in each row and column to get TP, FP, and FN for each class
