Q Set A
Let's consider a use case where PCA is applied to a dataset containing various features related to customer behavior in an ecommerce setting. The dataset includes variables such as purchase frequency, average order value, time spent on the website, and number of products viewed. Following are the loading vectors generated for PC and PC respectively. marks
V
V
purchase frequency
average order value
time spent on the website
number of products
Interpret the loading vectors with respect to PC and PC Comment on what does a datapoint with high PC and a datapoint with high PC indicate regarding the customer segment it belongs to

Q Set A
Which activation function can be used in the output layers of two different Artificial Neural Network designed for the following two use cases. Explain how the corresponding activation functions work and why are they suitable for their corresponding use cases. Marks
A healthcare organization wants to develop a system to diagnose diseases based on a set of medical symptoms provided by patients. The goal is to classify the diseases into mutually exclusive categories, such as "Common Cold," "Influenza," and "Strep Throat," based on the symptoms reported by the patients.
A movie streaming platform wants to classify movies into multiple genres based on their plot summaries and metadata. The goal is to categorize each movie into multiple nonexclusive genres, such as "Action," "Comedy," "Drama," "Romance," and "Thriller," to improve movie recommendations and user experience.
