The document describes a mini project on building a movie recommendation system. It includes an abstract that discusses different recommendation approaches like demographic, content-based, and collaborative filtering. It also outlines the problem statement, proposed solution, workflow, dataset description, algorithm details, GUI design, result analysis, and applications. The system uses a user-based collaborative filtering model to recommend movies to users based on their preferences and ratings of similar users. Evaluation shows it has good prediction performance.
We have built an online Movie Recommender System which is based on the analysis of users' ratings history to several movies and their demographic information. We used data from Movielens website. Collaborative filtering and matrix factorization techniques have been used for the implementation. The end result is a web application where a user is recommended with top 20 movies.

Demo Video: http://goo.gl/VgZ2uI
The goal of a recommender system is to predict the degree to which a user will like or dislike a set of items, such as movies or TV shows.
Most recommender systems use a combination of different approaches, but broadly speaking there are three different methods that can be used: Content analysis, Social recommendations and Collaborative filtering.
• Performed memory-based collaborative filtering techniques like Cosine similarities, Pearson’s r & model-based Matrix Factorization techniques like Alternating Least Squares (ALS) method
• Studied the scalability of these methods on local machines & on Hadoop clusters

In recent years, a huge amount of information is available on the internet and it is very difficult for the user to collect the relevant information. While purchasing any product also a lot of choices available and the user is confused about what to choose. This will be a time-consuming process as well. The search engine will solve this problem to some extent by but it will fail in giving a personalized recommendation. In this presentation, I will describe the different types and working of the recommender system how they gather the data, build recommender, generate recommendations from it, evaluate the performance and effectiveness of the recommender system. The further part of the presentation will describe how to build a movie recommender system using python.

Recommendation system is categorized in three classes: Collaborative Filtering, Content based and hybrid based Approach. This paper classifies collaborative filtering in two types: Memory based and Model based Recommendation .The paper elaborates these approaches and their techniques with their limitations. The result of our system provides much better recommendations to users because it enables the users to understand the relation between their emotional states and the recommended movies.
FIND MY VENUE: Content & Review Based Location Recommendation SystemIJTET Journal
Abstract—Recommender system is a software application agent that presents the culls, interest and predilections of individual persons/ users and makes recommendation accordingly. During the online search they provide more facile method for users to make decisions predicated on their recommendations. Collaborative filtering (CF) technique is utilized, which is predicated on past group community opinions for utilizer and item and correlates them to provide results to the utilizer queries. Here the LARS is a location cognizant recommender system to engender location recommendation by utilizing location predicated ratings within a single framework. The system suggests k items personalized for a querying utilizer u. For traditional system which could not fortify spatial properties of users, community opinion can be expressed through triple explicit ratings that are (utilizer, rating, item) which represents a utilizer providing numeric ratings for an item. LARS engenders recommendation through taxonomy of three types of location predicated ratings. Namely spatial ratings for non-spatial items, non-spatial ratings for spatial items, spatial ratings for spatial items. Through this LARS can apply with the Content & Review Predicated Location Recommendation System. Which gives a culled utilizer a group of venues or ads by giving thought to each personal interest and native predilection. This system deals with offline modeling and on-line recommendation. To get the instant results, a ascendable question process technique is developed by elongating each the edge rule with Threshold Algorithm.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Movies Recommendation system 2
3. Abstract
● A recommendation engine filters the data using different algorithms and
recommends the most relevant items to users. It first captures the past
behavior of a customer and based on that, recommends products which the
users might be likely to buy. If a completely new user visits an e-commerce
site, that site will not have any past history of that user. So how does the site
go about recommending products to the user in such a scenario? One
possible solution could be to recommend the best selling products, i.e. the
products which are high in demand. Another possible solution could be to
recommend the products which would bring the maximum profit to the business.

4. Abstract cont...
● Three main approaches are used for our recommender systems. One is Demographic
Filtering i.e They offer generalized recommendations to every user, based on movie
popularity and/or genre. The System recommends the same movies to users with
similar demographic features. Since each user is different , this approach is
considered to be too simple. The basic idea behind this system is that movies that are
more popular and critically acclaimed will have a higher probability of being liked by
the average audience. Second is content-based filtering, where we try to profile the
users interests using information collected, and recommend items based on that
profile. The other is collaborative filtering, where we try to group similar users
together and use information about the group to make recommendations to the user.
Movies Recommendation system 4
5. Introduction
● A recommendation system is a type of information filtering system which attempts to
predict the preferences of a user, and make suggestions based on these preferences.
There are a wide variety of applications for recommendation systems.
● These have become increasingly popular over the last few years and are now utilized
in most online platforms that we use.
● The content of such platforms varies from movies, music, books and video, to friends
and stories on social media platforms, to products on e-commerce websites, to people
on professional and dating websites, to search results returned on Google.

6. Introduction
● Often, these systems are able to collect information about a user’s choices, and can
use this information to improve their suggestions in the future.
● For example, if Amazon observes that a large number of customers who buy the
latest Apple MacBook also buy a USB-C-to USB Adapter, they can recommend the
Adapter to a new user who has just added a MacBook to his cart.

The movie recommendation system will be built using artificial algorithms that
analyze user's favorite genres and recommend movies according to their liking. The
response will be based on the liking of the user. The User will submit queries
depending on their liking of their movies. The System analyses the liking and then
recommends the user movies. Providing related content out of relevant and irrelevant

10. Dataset Description
Movies Recommendation system
The dataset used was from MovieLens, and is publicly available
at http://grouplens.org/datasets/movielens/latest. In order to keep the recommender
simple, I used the smallest dataset available (ml-latest-small.zip), which at the time of
download contained 105339 ratings and 6138 tag applications across 10329 movies.
These data were created by 668 users between April 03, 1996 and January 09, 2016. This
dataset was generated on January 11, 2016.
The data are contained in four files: links.csv, movies.csv, ratings.csv and tags.csv. I only
use the files movies.csv and ratings.csv to build a recommendation system.
A summary of movies is given below, together with several first rows of a data frame:
10
11. ● Both usersId and movieId are presented as integers and should be changed to factors.
Genres of the movies are not easily usable because of their format, I will deal with
this in the next step. 11
12. Data Pre-processing
Some pre-processing of the data available is required before creating the
recommendation system. First of all, I will re-organize the information of movie
genres in such a way that allows future users to search for
the movies they like within specific genres. From the design perspective, this is
much easier for the user compared to selecting a movie from a single very long list
of all the available movies.

13. Extract a list of genres
I use a one-hot encoding to create a matrix of corresponding genres for each movie.

Movies Recommendation system
USER-based Collaborative Filtering Model
According to this approach, given a new user, its similar users are first identified. Then, the top-rated
items rated by similar users are recommended.
For each new user, these are the steps:
• Measure how similar each user is to the new one. Like IBCF, popular similarity measures are
correlation and cosine.
• Identify the most similar users. The options are:
Take account of the top k users (k-nearest_neighbors)
Take account of the users whose similarity is above a defined threshold
• Rate the movies rated by the most similar users. The rating is the average rating among similar users
and the approaches are:
Average rating
Weighted average rating, using the similarities as weights
• Pick the top-rated movies.

16Movies Recommendation system
17. ● A good performance index is the area under the curve (AUC), that is, the area under the ROC curve. Even
without computing it, the chart shows that the highest is UBCF with cosine distance, so it’s the best-
performing technique.
● The UBCF with cosine distance is still the top model. Depending on what is the main purpose of the system,
an appropriate number of items to recommend should be defined. 17

20. Conclusion
Movies Recommendation system
In our project, a collaborative filtering algorithm is used to predict a user's movie rating. The
MovieLens dataset, which has 10 million ratings, is selected in our project and divided into
training set and test set. The RMSE method is used for algorithm evaluation. According to
evaluation as a result, our movie recommender system has pretty good prediction
performance.
A hybrid approach is taken between context based filtering and collaborative filtering to
implement the system. This approach overcomes drawbacks of each individual algorithm and
improves the performance of the system. Techniques like Clustering, Similarity and
Classification are used to get better recommendations thus reducing MAE and increasing
precision and accuracy. In future we can work on hybrid recommender using clustering and
similarity for better performance. Our approach can be further extended to other domains to
recommend songs, video, venue, news, books, tourism and e-commerce sites, etc.
