What is RECOMMENDER SYSTEM? What does RECOMMENDER SYSTEM mean? RECOMMENDER SYSTEM meaning - RECOMMENDER SYSTEM definition - RECOMMENDER SYSTEM explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. Recommender systems or recommendation systems (sometimes replacing "system" with a synonym such as platform or engine) are a subclass of information filtering system that seek to predict the "rating" or "preference" that a user would give to an item. Recommender systems have become extremely common in recent years, and are utilized in a variety of areas: some popular applications include movies, music, news, books, research articles, search queries, social tags, and products in general. There are also recommender systems for experts, collaborators, jokes, restaurants, garments, financial services, life insurance, romantic partners (online dating), and Twitter pages. Recommender systems typically produce a list of recommendations in one of two ways – through collaborative and content-based filtering or the personality-based approach. Collaborative filtering approaches building a model from a user's past behavior (items previously purchased or selected and/or numerical ratings given to those items) as well as similar decisions made by other users. This model is then used to predict items (or ratings for items) that the user may have an interest in. Content-based filtering approaches utilize a series of discrete characteristics of an item in order to recommend additional items with similar properties. These approaches are often combined (see Hybrid Recommender Systems). The differences between collaborative and content-based filtering can be demonstrated by comparing two popular music recommender systems – Last.fm and Pandora Radio. Last.fm creates a "station" of recommended songs by observing what bands and individual tracks the user has listened to on a regular basis and comparing those against the listening behavior of other users. Last.fm will play tracks that do not appear in the user's library, but are often played by other users with similar interests. As this approach leverages the behavior of users, it is an example of a collaborative filtering technique. Pandora uses the properties of a song or artist (a subset of the 400 attributes provided by the Music Genome Project) in order to seed a "station" that plays music with similar properties. User feedback is used to refine the station's results, deemphasizing certain attributes when a user "dislikes" a particular song and emphasizing other attributes when a user "likes" a song. This is an example of a content-based approach. Each type of system has its own strengths and weaknesses. In the above example, Last.fm requires a large amount of information on a user in order to make accurate recommendations. This is an example of the cold start problem, and is common in collaborative filtering systems. While Pandora needs very little information to get started, it is far more limited in scope (for example, it can only make recommendations that are similar to the original seed). Recommender systems are a useful alternative to search algorithms since they help users discover items they might not have found by themselves. Interestingly enough, recommender systems are often implemented using search engines indexing non-traditional data. Montaner provided the first overview of recommender systems from an intelligent agent perspective. Adomavicius provided a new, alternate overview of recommender systems. Herlocker provides an additional overview of evaluation techniques for recommender systems, and Beel et al. discussed the problems of offline evaluations. Beel et al. have also provided literature surveys on available research paper recommender systems and existing challenges.

SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ An information filtering system is a system that removes redundant or unwanted information from an information stream using (semi)automated or computerized methods prior to presentation to a human user. Its main goal is the management of the information overload and increment of the semantic signal-to-noise ratio. To do this the user's profile is compared to some reference characteristics. These characteristics may originate from the information item (the content-based approach) or the user's social environment (the collaborative filtering approach). Whereas in information transmission signal processing filters are used against syntax-disrupting noise on the bit-level, the methods employed in information filtering act on the semantic level. The range of machine methods employed builds on the same principles as those for information extraction. A notable application can be found in the field of email spam filters. Thus, it is not only the information explosion that necessitates some form of filters, but also inadvertently or maliciously introduced pseudo-information. On the presentation level, information filtering takes the form of user-preferences-based newsfeeds, etc. Recommender systems and content discovery platforms are active information filtering systems that attempt to present to the user information items (film, television, music, books, news, web pages) the user is interested in. These systems add information items to the information flowing towards the user, as opposed to removing information items from the information flow towards the user. Recommender systems typically use collaborative filtering approaches or a combination of the collaborative filtering and content-based filtering approaches, although content-based recommender systems do exist.

Personalized Music Recommendation by Mining Social Media Tags
 
01:11
Title: Personalized Music Recommendation by Mining Social Media Tags Domain: Data Mining Description: Over the past few years, the recommender system has been proposed as a critical role to help users choose the preferred product from a massive amount of data. For music recommendation, most recent recommender systems made attempts to associate music with the user’s preferences primarily based on user ratings. However, this kind of recommendation mechanism encounters the problem called rating diversity that makes the prediction results unreliable. To cope with this problem, in this paper, we propose a novel music recommendation approach that utilizes social media tags instead of ratings to calculate the similarity between music pieces. Through the proposed tag-based similarity, the user preferences hidden in tags can be inferred effectively. The empirical evaluations on real social media datasets reveal that our proposed approach using social tags outperforms the existing ones using only ratings in terms of predicting the user’s preferences to music.

A Multi-Armed Bandit Framework for Recommendations at Netflix | DataEngConf SF '18
 
35:37
Don’t miss the next DataEngConf in Barcelona: https://dataeng.co/2O0ZUq7 Download Slides: https://dataeng.co/2sied03 ABOUT THE TALK: In this talk, we will present a general multi-armed bandit framework for recommending titles to our 117M+ members on the Netflix homepage. A key aspect of our framework is closed loop attribution to link how our members respond to a recommendation. Our framework performs frequent updates of policies using user feedback collected from a past time interval window. We will take deeper look at the system architecture. We will illustrate the use of that framework by focusing on two example policies – a greedy exploit policy which maximize the probability a user will play a title and an incrementality-based policy. The latter is a novel online learning approach that takes the causal effect of a recommendation into account. An incrementality-based policy recommends titles that brings about the maximum increase in a specific quantity of interest, such as engagement. This helps discount the effect of recommendations when a user would have played anyway. We describe offline experiments and online A/B test results for both of these example policies. ABOUT THE SPEAKERS: Jaya Kawale is a Senior Research Scientist at Netflix working on problems related to targeting and recommendations. She received her PhD in Computer Science from the University of Minnesota and has published research papers at several top-tier conferences. Her main areas of interest are large scale machine learning and data mining. Elliot is a software engineer at Netflix on the Personalization Infrastructure team. Currently, he builds big data systems for personalizing recommendations for Netflix subscribers, using a variety of technologies including Scala, Spark/Spark Streaming, Kafka, and Cassandra. He graduated from UC Berkeley (B.S.) and Stanford (M.S.) and has previously worked at eBay and Apple.

Data Mining Certification Training Course Content : https://www.excelr.com/data-mining/ Introduction to Data Mining Tutorials : https://youtu.be/uNrg8ep_sEI What is Data Mining? Big data!!! Are you demotivated when your peers are discussing about data science and recent advances in big data. Did you ever think how Flip kart and Amazon are suggesting products for their customers? Do you know how financial institutions/retailers are using big data to transform themselves in to next generation enterprises? Do you want to be part of the world class next generation organisations to change the game rules of the strategy making and to zoom your career to newer heights? Here is the power of data science in the form of Data mining concepts which are considered most powerful techniques in big data analytics. Data Mining with R unveils underlying amazing patterns, wonderful insights which go unnoticed otherwise, from the large amounts of data. Data mining tools predict behaviours and future trends, allowing businesses to make proactive, unbiased and scientific-driven decisions. Data mining has powerful tools and techniques that answer business questions in a scientific manner, which traditional methods cannot answer. Adoption of data mining concepts in decision making changed the companies, the way they operate the business and improved revenues significantly. Companies in a wide range of industries such as Information Technology, Retail, Telecommunication, Oil and Gas, Finance, Health care are already using data mining tools and techniques to take advantage of historical data and to create their future business strategies. Data mining can be broadly categorized into two branches i.e. supervised learning and unsupervised learning. Unsupervised learning deals with identifying significant facts, relationships, hidden patterns, trends and anomalies. Clustering, Principle Component Analysis, Association Rules, etc., are considered unsupervised learning. Supervised learning deals with prediction and classification of the data with machine learning algorithms. Weka is most popular tool for supervised learning.

It's a recommender system to recommend books using various algorithms. It uses GoodReads books data from kaggle. Our aim is to recommend user books from the huge collections of books available that he must not have read and would like to read next based on his previous book choices. This is a good problem to solve because many recommender systems have been created to suggest various products on e-commerce sites and movie-related sites, But no one has worked on such large data of books to recommend books. Viewing it from the user's perspective, this idea will reduce user’s effort to search the books to be read next that are inclined towards his interest. Presentation Link : goo.gl/6iJpjv

Jure Leskovec: "Large-scale Graph Representation Learning"
 
49:48
New Deep Learning Techniques 2018 "Large-scale Graph Representation Learning" Jure Leskovec, Stanford University Abstract: Machine learning on graphs is an important and ubiquitous task with applications ranging from drug design to friendship recommendation in social networks. The primary challenge in this domain is finding a way to represent, or encode, graph structure so that it can be easily exploited by machine learning models. However, traditionally machine learning approaches relied on user-defined heuristics to extract features encoding structural information about a graph. In this talk I will discuss methods that automatically learn to encode graph structure into low-dimensional embeddings, using techniques based on deep learning and nonlinear dimensionality reduction. I will provide a conceptual review of key advancements in this area of representation learning on graphs, including random-walk based algorithms, and graph convolutional networks.

Travel recommendation by mining people attributes
 
16:33
Project by V.Thanigaivel VM5416 T.Arivazhagan VM5402 V.V.Vivek VM5410 The main abstract of this project is concerned with recommendation of places for a user based upon the hugely available community contributed pictures and people attributes. Leveraging community-contributed data (e.g., blogs, GPS logs, and geo-tagged photos) for personalized recommendation is one of the active research problems since there are rich contexts and human activities in such explosively growing data. In this work, we focus on personalized travel recommendation and show promising applications by leveraging the freely available community-contributed photos. We propose to conduct personalized travel recommendation by further considering specific user profiles or attributes (e.g., gender) as well as travel group types (e.g., family & friends, couple). Instead of mining photo logs only, we exploit the automatically detected people attributes. This is a very useful project for people who loves long travel and want to visit innovative places. By using the matlab we are detecting the gender and number of people who went for travel to that place.

Pondicherry Office: JP INFOTECH, #45, Kamaraj Salai,Thattanchavady, Puducherry -9.Landmark: Next to VVP Nagar Arch. Mobile: (0) 9952649690, Email: [email protected], web: http://www.jpinfotech.org, Blog: http://www.jpinfotech.blogspot.com Rail accidents represent an important safety concern for the transportation industry in many countries. In the 11 years from 2001 to 2012, the U.S. had more than 40 000 rail accidents that cost more than $45 million. While most of the accidents during this period had very little cost, about 5200 had damages in excess of $141 500. To better understand the contributors to these extreme accidents, the Federal Railroad Administration has required the railroads involved in accidents to submit reports that contain both fixed field entries and narratives that describe the characteristics of the accident. While a number of studies have looked at the fixed fields, none have done an extensive analysis of the narratives. This paper describes the use of text mining with a combination of techniques to automatically discover accident characteristics that can inform a better understanding of the contributors to the accidents. The study evaluates the efficacy of text mining of accident narratives by assessing predictive performance for the costs of extreme accidents. The results show that predictive accuracy for accident costs significantly improves through the use of features found by text mining and predictive accuracy further improves through the use of modern ensemble methods. Importantly, this study also shows through case examples how the findings from text mining of the narratives can improve understanding of the contributors to rail accidents in ways not possible through only fixed field analysis of the accident reports.

What is TERMINOLOGY EXTRACTION? What does TERMINOLOGY EXTRACTION mean?

What is TERMINOLOGY EXTRACTION? What does TERMINOLOGY EXTRACTION mean? TERMINOLOGY EXTRACTION meaning - TERMINOLOGY EXTRACTION definition - TERMINOLOGY EXTRACTION explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. Terminology extraction (also known as term extraction, glossary extraction, term recognition, or terminology mining) is a subtask of information extraction. The goal of terminology extraction is to automatically extract relevant terms from a given corpus. In the semantic web era, a growing number of communities and networked enterprises started to access and interoperate through the internet. Modeling these communities and their information needs is important for several web applications, like topic-driven web crawlers, web services, recommender systems, etc. The development of terminology extraction is essential to the language industry. One of the first steps to model the knowledge domain of a virtual community is to collect a vocabulary of domain-relevant terms, constituting the linguistic surface manifestation of domain concepts. Several methods to automatically extract technical terms from domain-specific document warehouses have been described in the literature. Typically, approaches to automatic term extraction make use of linguistic processors (part of speech tagging, phrase chunking) to extract terminological candidates, i.e. syntactically plausible terminological noun phrases, NPs (e.g. compounds "credit card", adjective-NPs "local tourist information office", and prepositional-NPs "board of directors" - in English, the first two constructs are the most frequent). Terminological entries are then filtered from the candidate list using statistical and machine learning methods. Once filtered, because of their low ambiguity and high specificity, these terms are particularly useful for conceptualizing a knowledge domain or for supporting the creation of a domain ontology or a terminology base. Furthermore, terminology extraction is a very useful starting point for semantic similarity, knowledge management, human translation and machine translation, etc. The methods for terminology extraction can be applied to parallel corpora. Combined with e.g. co-occurrence statistics, candidates for term translations can be obtained. Bilingual terminology can be extracted also from comparable corpora (corpora containing texts within the same text type, domain but not translations of documents between each other).

Orchestrating the Intelligent Web with Apache Mahout
 
48:21
Presenter(s): Aneesha Bakharia URL: http://2011.linux.conf.au/programme/schedule/view_talk/213 Presenters: Aneesha Bakharia ([email protected]) and Aaron Tan ([email protected]) It is becoming increasingly important to incorporate “collective intelligence” within web, mobile and business intelligence applications. Traditionally the implementation of algorithms capable of adding intelligence to an application either required a highly specialised knowledge of machine learning or was extremely costly. Apache Mahout is one of the first open source and scalable machine learning libraries that seeks to mainstream the use of machine learning. This presentation will focus on providing the audience with a practical understanding of the algorithms included in Apache Mahout and how they can be used to provide insight into the patterns that exist in large amounts of data? Text clustering with the Latent Dirichlet Algorithm will also be covered. The Apache Mahout library consists of scalable machine learning algorithms for data mining tasks that encompass classification (Naïve Bayes and Support Vector Machines), clustering (k­means, Expectation Maximization, Mean Shift, Latent Dirichlet Allocation and Hierarchical Clustering), recommendation (collaborative filtering) and frequent pattern mining (parallel fp-growth). As of the 0.3 release, an impressive total of 25 machine learning algorithms have been implemented. Apache Mahout achieves scalability by leveraging Apache Hadoop which implements the MapReduce parallel processing paradigm that was first made popular by Google. Latent Dirichlet Allocation is a relatively new algorithm first introduced in 2003 with a suggested use in Topic Modeling (text clustering). Unlike generic clustering algorithms such as k-means, Latent Dirichlet Allocation is able to model document overlap. Latent Dirichlet Allocation is not a hard clustering algorithm and is able to map documents and words to multiple clusters. This feature is a natural fit for documents, which usually discuss multiple topics. The Latent Dirichlet Allocation algorithm simultaneously groups both documents and words into clusters. This is a useful feature as the main words belonging to a cluster and the prominent documents within a cluster are both output by the algorithm. Twitter recently released a feature called Lists that allows you to group people you follow and view the timeline of Tweets for users in a List separately. We will use the Latent Dirichlet Allocation algorithm to cluster people you follow and suggest Lists for Twitter. This will serve as a practical overview of using Apache Mahout for clustering. The following topics of interest are: - What is machine learning? - What is Apache Mahout? - Who is using Apache Mahout? - The MapReduce paradigm - Machine learning with Apache Mahout - Clustering with Apache Mahout - Classification with Apache Mahout - Collaborative Filtering with Apache Mahout - Frequent Pattern Mining with Apache Mahout - Processing Large Datasets with Multiple Cluster Nodes - Building a Twitter List recommendation application with the Latent Dirichlet Allocation algorithm http://2011.linux.conf.au/ - http://www.linux.org.au CC BY-SA - http://creativecommons.org/licenses/by-sa/4.0/legalcode.txt
