A recommender system or a recommendation system is a subclass of information filtering systems that seeks to predict the "rating" or "preference" a user would give to an item. (Wiki) The goal of a Recommender System is to generate meaningful recommendations to a collection of users for items or products that might interest them. (Melville, Sindhwani) Recommender systems reduce the information/choice overload by estimating the relevance

Recommender systems using collaborative filtering
This document summarizes a student project on implementing recommender systems. The project objectives were to design a website using user-based, item-based, and model-based collaborative filtering as well as MapReduce to generate movie recommendations. The system was tested on the MovieLens dataset using MAE and RMSE metrics, with user-based filtering found to have the best performance. The document outlines the technical aspects of the recommendation system including the technologies used, website architecture, and references.
An introduction to Recommender Systems
Recommender systems are software agents that analyze a user's preferences through transactions and provide personalized recommendations accordingly. There are several recommendation paradigms including non-personalized rules, personalized rules based on user data, and transaction-based collaborative filtering that learns from user interactions. Context-based recommender systems also consider additional information like time, location, or device to provide adaptive recommendations. Common techniques used in recommender systems include content-based filtering that recommends similar items, collaborative filtering that finds users with similar tastes, and demographic-based recommendations.

Recommendation system
Recommendation systems provide users with information they may be interested in based on their preferences and interests. They help address the problem of information overload by retrieving desired information for the user based on their preferences or those of similar users. The two main types of recommendation systems are personalized and non-personalized systems. Common techniques used include collaborative filtering, which finds users with similar tastes, and content-based filtering, which recommends items similar to those a user has liked based on item attributes.

Lessons Learned from Building Machine Learning Software at Netflix
Talk from Software Engineering for Machine Learning Workshop (SW4ML) at the Neural Information Processing Systems (NIPS) 2014 conference in Montreal, Canada on 2014-12-13.
Abstract:
Building a real system that incorporates machine learning as a part can be a difficult effort, both in terms of the algorithmic and engineering challenges involved. In this talk I will focus on the engineering side and discuss some of the practical issues we’ve encountered in developing real machine learning systems at Netflix and some of the lessons we’ve learned over time. I will describe our approach for building machine learning systems and how it comes from a desire to balance many different, and sometimes conflicting, requirements such as handling large volumes of data, choosing and adapting good algorithms, keeping recommendations fresh and accurate, remaining responsive to user actions, and also being flexible to accommodate research and experimentation. I will focus on what it takes to put machine learning into a real system that works in a feedback loop with our users and how that imposes different requirements and a different focus than doing machine learning only within a lab environment. I will address the particular software engineering challenges that we’ve faced in running our algorithms at scale in the cloud. I will also mention some simple design patterns that we’ve fond to be useful across a wide variety of machine-learned systems.

Representative algorithms from each category are discussed and analyzed in terms of their predictive performance and ability to address collaborative filtering challenges. The document concludes with a discussion of evaluating collaborative filtering algorithms and commonly used datasets.
Recommendation Systems Basics
Recommendation systems, also known as recommendation engines, are a type of information system whose purpose is to suggest, or recommend items or actions to users.
The recommendations may consist of:
-> retail items (movies, books, etc.) or
-> actions, such as following other users in a social network.
It can be said that, Recommendation engines are nothing but an automated form of a “shop counter guy”. You ask him for a product. Not only he shows that product, but also the related ones which you could buy. They are well trained in cross selling and up selling. So, does our recommendation engines.

Recommendation System Using Social Networking
With the proliferation of electronic commerce and knowledge economy environment both organizations and
individuals generate and consume a large amount of online information. With the huge availability of
product information on website, many times it becomes difficult for a consumer to locate item he wants to
buy. Recommendation Systems [RS] provide a solution to this. Many websites such as YouTube, e-Bay,
Amazon have come up with their own versions of Recommendation Systems. However Issues like lack of
data, changing data, changing user preferences and unpredictable items are faced by these
recommendation systems. In this paper we propose a model of Recommendation systems in e-commerce
domain which will address issues of cold start problem and change in user preference problem. Our work
proposes a novel recommendation system which incorporates user profile parameters obtained from Social
Networking website. Our proposed model SNetRS is a collaborative filtering based algorithm, which
focuses on user preferences obtained from FaceBook. We have taken domain of books to illustrate our
model.

To utilize Large Language Models (LLMs) for content-based recommendation systems in entertainment platforms, follow these steps:
Data Collection: Gather diverse datasets of entertainment content with metadata.
Preprocessing: Clean, tokenize, and encode textual data for model input.
Model Selection: Choose an LLM architecture like GPT-3 and fine-tune it on the dataset.
Feature Extraction: Extract relevant features from the data, such as genre, keywords, and sentiment.
Recommendation Generation: Utilize the fine-tuned LLM to generate personalized recommendations based on user preferences and content features.
Evaluation and Optimization: Assess recommendation quality and iterate for continual improvement.

Collaborative Filtering 1: User-based CF
This document discusses recommender systems and collaborative filtering. It introduces user-based collaborative filtering, which predicts a user's rating for an item based on the ratings from similar users. Similarity between users is calculated using the Pearson correlation coefficient. The ratings of the top K most similar users are then averaged to predict the target user's rating.

Recommender Systems
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.

Global Situational Awareness of A.I. and where its headed
You can see the future first in San Francisco.
Over the past year, the talk of the town has shifted from $10 billion compute clusters to $100 billion clusters to trillion-dollar clusters. Every six months another zero is added to the boardroom plans. Behind the scenes, there’s a fierce scramble to secure every power contract still available for the rest of the decade, every voltage transformer that can possibly be procured. American big business is gearing up to pour trillions of dollars into a long-unseen mobilization of American industrial might. By the end of the decade, American electricity production will have grown tens of percent; from the shale fields of Pennsylvania to the solar farms of Nevada, hundreds of millions of GPUs will hum.
The AGI race has begun. We are building machines that can think and reason. By 2025/26, these machines will outpace college graduates. By the end of the decade, they will be smarter than you or I; we will have superintelligence, in the true sense of the word. Along the way, national security forces not seen in half a century will be un-leashed, and before long, The Project will be on. If we’re lucky, we’ll be in an all-out race with the CCP; if we’re unlucky, an all-out war.
Everyone is now talking about AI, but few have the faintest glimmer of what is about to hit them. Nvidia analysts still think 2024 might be close to the peak. Mainstream pundits are stuck on the wilful blindness of “it’s just predicting the next word”. They see only hype and business-as-usual; at most they entertain another internet-scale technological change.
Before long, the world will wake up. But right now, there are perhaps a few hundred people, most of them in San Francisco and the AI labs, that have situational awareness. Through whatever peculiar forces of fate, I have found myself amongst them. A few years ago, these people were derided as crazy—but they trusted the trendlines, which allowed them to correctly predict the AI advances of the past few years. Whether these people are also right about the next few years remains to be seen. But these are very smart people—the smartest people I have ever met—and they are the ones building this technology. Perhaps they will be an odd footnote in history, or perhaps they will go down in history like Szilard and Oppenheimer and Teller. If they are seeing the future even close to correctly, we are in for a wild ride.
Let me tell you what we see.

ViewShift: Hassle-free Dynamic Policy Enforcement for Every Data Lake
Dynamic policy enforcement is becoming an increasingly important topic in today’s world where data privacy and compliance is a top priority for companies, individuals, and regulators alike. In these slides, we discuss how LinkedIn implements a powerful dynamic policy enforcement engine, called ViewShift, and integrates it within its data lake. We show the query engine architecture and how catalog implementations can automatically route table resolutions to compliance-enforcing SQL views. Such views have a set of very interesting properties: (1) They are auto-generated from declarative data annotations. (2) They respect user-level consent and preferences (3) They are context-aware, encoding a different set of transformations for different use cases (4) They are portable; while the SQL logic is only implemented in one SQL dialect, it is accessible in all engines.

End-to-end pipeline agility - Berlin Buzzwords 2024
We describe how we achieve high change agility in data engineering by eliminating the fear of breaking downstream data pipelines through end-to-end pipeline testing, and by using schema metaprogramming to safely eliminate boilerplate involved in changes that affect whole pipelines.
A quick poll on agility in changing pipelines from end to end indicated a huge span in capabilities. For the question "How long time does it take for all downstream pipelines to be adapted to an upstream change," the median response was 6 months, but some respondents could do it in less than a day. When quantitative data engineering differences between the best and worst are measured, the span is often 100x-1000x, sometimes even more.
A long time ago, we suffered at Spotify from fear of changing pipelines due to not knowing what the impact might be downstream. We made plans for a technical solution to test pipelines end-to-end to mitigate that fear, but the effort failed for cultural reasons. We eventually solved this challenge, but in a different context. In this presentation we will describe how we test full pipelines effectively by manipulating workflow orchestration, which enables us to make changes in pipelines without fear of breaking downstream.
Making schema changes that affect many jobs also involves a lot of toil and boilerplate. Using schema-on-read mitigates some of it, but has drawbacks since it makes it more difficult to detect errors early. We will describe how we have rejected this tradeoff by applying schema metaprogramming, eliminating boilerplate but keeping the protection of static typing, thereby further improving agility to quickly modify data pipelines without fear.

Introduction to recommender systems
- 1. Introduction to Recommender Systems Rami Al-Salman
- 3. What is a recommender system? A recommender system, or a recommendation system is a subclass of information filtering system that seeks to predict the "rating" or "preference" a user would give to an item. (Wiki) The goal of a Recommender System is to generate meaningful recommendations to a collection of users for items or products that might interest them. (Melville, Sindhwani) Recommender systems reduce the information/choice overload by estimate the relevance
- 8. Business value of recommender systems Netflix: 75% of the movies watched Amazon: 35% sales Youtube : 38% more clickthrough https://arxiv.org/pdf/1908.08328.pdf
- 9. Sources of information for recommender systems Explicit ratings e.g, 5-stars, 1 star, etc Explicit binary ratings (thumbs up/thumbs down) Implicit information, e.g., how many times was it viewed? User profiles/preferences Item features
- 10. Recommender System general overview Recommendations Engine Id score 6 0.9 2 0.88 555 0.6 666 0.3 Recommendations Users Profiles & Contextual parameters Item Features
- 11. Classes of recommendation approaches (Burke, R, 2007) Content-based Collaborative filtering Demographic Community-based Hybrid approach
- 12. Content-based When a user liked an item, we try to recommend items that are similar to the the user liked in the past. The recommended items share some characteristics and features values with the liked item. If the user watched a horror movie and liked it, then next time we recommend horror movies with similar features i.e., description. Watched by a user Similar movies Recommended to user
- 13. Collaborative filtering (CF) Recommends to the active user the items that other users with similar tastes liked in the past. The similarity in taste of two users is calculated based on the similarity in the rating history of the users. CF is the most used and famous technique Watched by both users Similar users Watched by him, recommended to her
- 14. Collaborative Filtering (CF) Memory-based ● User-User ● Item-Item Model based: ● Matrix Factorization ● Deep learning
- 15. Memory-based (User-User) Harry Potter 1 Harry Potter 2 Host The Hunt User1 ? ? User2 ? User3 ? ? User4 ? ? ? Given users and movies, will user User1 like the Host and The Hunt movies?
- 16. Memory-based (User-User) Harry Potter 1 Harry Potter 2 Host The Hunt User1 1 1 ? ? User2 1 1 1 ? User3 ? 1 1 ? User4 ? ? ? 1 Get the most similar N-neighbour users. For simplicity, lets N to be 1 Given the most similar user, use what he/she liked to recommend to the source user For similarity, several functions can be used, e.g., Jaccard Similarity, Cosine similarity, etc
- 17. Memory-based (User-User) Harry Potter 1 Harry Potter 2 Host The Hunt User1 1 1 ? User2 1 1 1 ? User3 ? 1 1 ? User4 ? ? ? 1 Jaccard Similarity: Sim(A,B) = |A ∩ B| / |A| + |B| - |A ∩ B| Sim(User1, User2) = 2 / 3 Sim(User1, User3) = 1 / 3 Sim(User1, User4) = 0 Based on that we can recommend Host movie from User2 to User1 1
- 19. Demographic We recommend items based on the demographic profile of the user. The assumption is that different recommendations should be generated for different demographic niches. E.g., adapte language or country for specific e-commerce website
- 20. Community-based This type of system recommends items based on the preferences of the users friends. This technique follows the epigram “Tell me who your friends are, and I will tell you who you are”. (Bellotti, V, etl, 2008).
- 21. Challenges Scalability of the algorithms with large and real-world datasets Proactive recommender systems, i.e., recommenders that decide to provide recommendations even if not explicitly requested Privacy preserving recommender systems Diversity of the items recommended to a target user
- 22. Summary Recommender Systems are everywhere and critical for businesses to success Several kinds of recommender systems were presented Collaborative Filtering is most widely used technique There are still many open challenges to be tackled in the context of the recommender systems
