Movie Recommendations via Item-Item Collaborative Filtering. You are providedwith real-data (Movie-Lens dataset) of user ratings for different movies. There is a readmefile that describes the data format. In this project, you will implement the item-item collab-orative filtering algorithm that we discussed in the class. The high-level steps are as follows: a) Construct the profile of each item (i.e., movie). At the minimum, you should use theratings given by each user for a given item (i.e., movie). Optionally, you can use other in-formation (e.g., genre information for each movie and tag information given by user for eachmovie) creatively. If you use this additional information, you should explain your method-ology in the submitted report. b) Compute similarity score for all item-item (i.e., movie-movie) pairs. You will employ thecentered cosine similarity metric that we discussed in class. c) Compute the neighborhood set Nfor each item (i.e. movie). You will select the moviesthat…

Embedded in Matlab is a .csv file called “Exam2_Q1.csv”; this file can be opened in Matlab. This file provides the (x, y, z) triples data you must use in this question. Load the file into a table via the built-in command. Plot this data in three dimensions using black dots or small black circles. On the same figure, plot the following equation as a surface: ?=((x+2y)/3). In a new figure, plot the same data and surface, but use the view command to display the surface edge-on to emphasize the scatter of the data around the surface. The csv file contains:
Implement a blog server in C 1. Implement get of all posts (GET /posts), and individual post (GET /post/1) 2. Implement creation of post (POST /posts). Allow the user to enter their name, but check that they are a valid user in db. Do error checking! The user should not specify the post id; that should come from the database. 3. Write three html files to test this; serve them with the blog server: index.html shows the list of posts with a link to each. post.html shows a post. publish.html allows the creation of a new post. Link these together as a user would expect!
g. Include a delete() function in LinearProbingHashST that deletes a key-value pair by changing the value to null (while leaving the key in place) and then deleting the pair from the table in resize(). The most difficult decision you must make is when to use resize(). Note: If a future put() action associates a new value with the key, you should replace the null value. Make sure that while deciding whether to enlarge or shrink the table, your programme takes into consideration both the number of such tombstone items and the number of vacant places.
