6. Building a Recommendation System with Collaborative Filtering 

Collaborative filtering is a recommendation system that uses the preferences of other users to recommend items to a given user. It is commonly used in e-commerce and streaming platform applications, such as Netflix and Amazon, to suggest items that the user may find interesting based on what other users with similar interests have liked or watched

• Collect user data about items they have liked or interacted with.
• Create a user-item matrix, a table containing information about each user and what items they have interacted with.
• Generate item-to-item similarity scores by calculating how similar the items are to each other based on the preferences of users who have interacted with both items.
• Use these similarity scores to generate recommendations for each user by matching them with items in the user-item matrix similar to those with whom they have already interacted.

8. Face Recognition using CNN

Convolutional Neural Networks (CNNs) can be used for facial recognition by taking pictures of faces and then learning the features of each face. CNN will learn each face’s features and then recognize a face when it is presented.

• Gather a dataset of labeled images. This dataset should contain images of people’s faces with labels for each image indicating which person is in the image.

• Pre-process the pictures by resizing, converting them to grayscale, and normalizing the pixel values.

• Split the dataset into training, validation, and testing sets.

• Design a Convolutional Neural Network (CNN) architecture. This may involve choosing the number of layers, the size of the kernels, the type of activation functions, and other hyperparameters.
