Q.11 Why should we avoid using the training data for evaluation?
Ans: This is because our model will simply remember the whole training set, and will therefore always predict the correct label for any point in the training set.
Q.12 What should be the value of F1 score if the model needs to have 100% accuracy?
Ans: The model will have an F1 score of 1 if it has to be 100% accurate.
Answer any 04 questions out of the given 06 questions (2X4=8)
Q.13 “Automatic summarization is used in NLP applications”. Is the given statement correct? Justify your answer with an example.
Ans: Yes, the given statement is correct. Automatic summarization is relevant not only for summarizing the meaning of documents and information, but also to understand the emotional meanings within the information, such as in collecting data from social media. Automatic summarization is especially relevant when used to provide an overview of a news item or blog post, while avoiding redundancy from multiple sources and maximizing the diversity of content obtained.
Q.14 Give an example of a situation wherein false positive would have a high cost associated with it.
Ans: Let us consider a model that predicts that a mail is spam or not. If the model always predicts that the mail is spam, people would not look at it and eventually might lose important information. Here False Positive condition (Predicting the mail as spam while the mail is not spam) would have a high cost.

Ans: The steps to implement bag of words algorithm are as follows:
Step 1: Text Normalisation: Collect data and pre-process it
Step 2: Create Dictionary: Make a list of all the unique words occurring in the corpus. (Vocabulary)
Step 3: Create document vectors: For each document in the corpus, find out how many times the word from the unique list of words has occurred.
Step 4: Create document vectors for all the documents.
Q.17 What is a confusion matrix? What is it used for?
Ans: The confusion matrix is used to store the results of comparison between the prediction and reality. From the confusion matrix, we can calculate parameters like recall, precision, F1 score which are used to evaluate the performance of an AI model.
Q.18 Explain from the given graph, how the value and occurrence of a word are related in a corpus?
SECTION C (2X4=8 marks) (COMPETENCY BASED QUESTIONS)
Answer any 02 questions out of the given 03 questions.
Q.19 Through a step-by-step process, calculate TFIDF for the given corpus.Document 1: Johny Johny, Yes Papa,Document 2: Eating sugar? No PapaDocument 3: Telling lies? No PapaDocument 4: Open your mouth, Ha! Ha! Ha!Ans:
Q.20 The world is competitive nowadays. People face competition in even the tiniest tasks and are expected to give their best at every point in time. When people are unable to meet these expectations, they get stressed and could even go into depression. We get to hear a lot of cases where people are depressed due to reasons like peer pressure, studies, family issues, relationships, etc. and they eventually get into something that is bad for them as well as for others. So, to overcome this, Cognitive Behavioural Therapy (CBT) is considered to be one of the best methods to address stress as it is easy to implement on people and also gives good results. This therapy includes understanding the behaviour and mindset of a person in their normal life. With the help of CBT, therapists help people overcome their stress and live a happy life.For the situation given above:1. Write the problem statement templateAns:
