  • Jussi Karlgren formulated the idea of a recommender system, or a “digital bookshelf,” in 1990.[1]
  • E-commerce and retail companies are leveraging the power of data and boosting sales by implementing recommender systems on their websites.[2]
  • Recommender systems aim to predict users’ interests and recommend product items that quite likely are interesting for them.[2]
  • If you’re running a successful business, you could probably survive without a recommender system.[2]
  • Within the context of launching a new product, implementing a recommendation system from scratch won’t be easy.[2]
  • The recommendation system in the tutorial uses the weighted alternating least squares (WALS) algorithm.[3]
  • This article outlines the background theory for matrix factorization-based collaborative filtering as applied to recommendation systems.[3]
  • You can find large scale recommender systems in retail, video on demand, or music streaming.[4]
  • In this tutorial, you will learn how to build a basic model of simple and content-based recommender systems.[5]
  • Recommender systems have also been developed to explore research articles and experts, collaborators, and financial services.[5]
  • YouTube uses the recommendation system at a large scale to suggest you videos based on your history.[5]
  • Item-based Filtering : these systems are extremely similar to the content recommendation engine that you built.[5]
  • Recommender systems were developed to address this need and many techniques were used for different approaches to the problem.[6]
  • Developing a recommender system that takes into account the social network of the user is another way of tackling the problem.[6]
  • Portals such as Amazon and Submarino use recommender systems to suggest products to their customers.[6]
  • Recommender systems try to predict the user's evaluation of an item that has not yet been evaluated.[6]
  • Modern recommender systems were created first by e-commerce giants like Amazon and then popularized by OTT platforms like Netflix.[7]
  • But before we dive deep into building a recommendation engine let’s add context to the analogy of using one with this example.[7]
  • Recommender systems are a critical tool to achieve these goals.[8]
  • In this blog post, we first review the common kinds of recommender systems in use today.[8]
  • To place the newer systems in context, let’s begin by reviewing well-established recommender systems.[8]
  • Researchers have experimented with many new approaches to recommender systems in the last few years.[8]
  • First, let's take a look at what a recommender system is and why such a system is required.[9]
  • The recommender system essentially addresses the information matching problem to better match user information with item information.[9]
  • A recommender system is required to determine which items should be ranked at the top and which ones should be ranked behind.[9]
  • A typical recommender system based on matching and ranking usually has two modules.[9]
  • Recommender systems are supposed to help us deal with these issues and make decisions that are more appropriate.[10]
  • Personalization, which should be handled from different angles, is another issue for recommendation systems.[10]
  • In this study, a contextually personalized hybrid location recommender system is developed.[10]
  • Existing recommender systems do not consider that the preferences of the users are affected by different contextual circumstances.[10]
  • To summarize, MAP computes the mean of the Average Precision (AP) over all the users for a recommendation system.[11]
  • This repository contains examples and best practices for building recommendation systems, provided as Jupyter notebooks.[12]
  • The market leader in collaborative filtering-based recommender systems.[13]
  • Recommender systems are machine learning-based systems that scan through all possible options and provides a prediction or recommendation.[14]
  • Recommender systems perform well, even if new items are added to the library.[14]
  • Netflix wants to build a recommendation system to predict a list of movies for users based on other movies' likes or dislikes.[14]
  • Recommendation systems can be used to predict the answers to precisely these questions, i.e. to determine yet unknown preferences for items.[15]
  • You would like to know more details about recommender systems?[15]
  • This blog post served as an overview of the different methodologies used in recommender systems.[15]
  • A recommender system aims to suggest products, services or items based on their prediction of user’s interests.[16]
  • The focus of companies that use recommender systems is on increasing sales.[16]
  • Recommendations given by recommender systems speed up searches and allow users to access that content in which they are interested.[16]
  • Recommender system works with two types of information.[16]
  • Below are older datasets, as well as datasets collected by my lab that are not related to recommender systems specifically.[17]
  • Collaborative filtering is arguably the most effective method for building a recommender system.[18]
  • Note that the attribute-aware recommender systems discussed in this paper are not equivalent to hybrid recommender systems.[18]
  • Finally, we cover the latest work on attribute-aware recommender systems.[18]
  • In practice, recommender systems learn to generate recommendations based on three types of approaches: pointwise, pairwise, and listwise.[18]
  • Most existing recommender systems implicitly assume one particular type of user behavior.[19]
  • The recommender system accepts user request, recommends N items to the user, and records user choice.[19]
  • Second, we propose a hybrid recommender system combining random and k-nearest neighbor algorithms.[19]
  • Third, we redefine the recall and diversity metrics based on the new scenario to evaluate the recommender system.[19]
  • In these cases, a recommender system for ephemeral groups of users is more suitable than (well-studied) recommender systems for individuals.[20]
  • In this paper we present a recommendation system for groups of users that go to the cinema.[20]
  • Therefore, in this article we will board the problem of recommender systems for ephemeral groups.[20]
  • In order to validate the performance of our recommendation system, we perform a preliminary set of experiments with 57 ephemeral groups.[20]
  • Recommender systems are an important class of machine learning algorithms that offer "relevant" suggestions to users.[21]
  • Practically, recommender systems encompass a class of techniques and algorithms which are able to suggest “relevant” items to users.[21]
  • The relevancy is something that the recommender system must determine and is mainly based on historical data.[21]
  • We can easily create a collaborative filtering recommender system using Graph Lab![21]
  • Recommender systems are machine learning systems that help users discover new product and services.[22]
  • Content-based recommender systems work well when descriptive data on the content is provided beforehand.[22]
  • Recommender systems work behind the scenes on many of the world's most popular websites.[22]
  • The design of such recommendation engines depends on the domain and the particular characteristics of the data available.[23]
  • Recommender systems are the systems that are designed to recommend things to the user based on many different factors.[24]
  • Netflix uses a recommender system to recommend movies & web-series to its users.[24]
  • It is a type of recommendation system which works on the principle of popularity and or anything which is in trend.[24]
  • It is another type of recommendation system which works on the principle of similar content.[24]
  • Recommender systems are a useful alternative to search algorithms since they help users discover items they might not have found otherwise.[25]
  • Recommender systems have been the focus of several granted patents.[25]
  • Many algorithms have been used in measuring user similarity or item similarity in recommender systems.[25]
  • Another common approach when designing recommender systems is content-based filtering.[25]
  • Scalability is a key factor when determining which type of recommender systems to use.[26]
  • In recommender systems, the user-item preference matrix is often very sparse with the majority of the entries being missing.[26]
  • The Youtube recommender system divided the modeling process into two steps.[26]
  • The videos watched outside Youtube site are not from the recommender system, and can effectively surface new content (Youtube|2016).[26]
