Algorithmic Music Recommendations at Spotify

Chris Johnson

Spotify uses a range of Machine Learning models to power its music recommendation features including the Discover page, Radio, and Related Artists. Due to the iterative nature of these models they are a natural fit to the Spark computation paradigm and suffer from the IO overhead incurred by Hadoop. In this talk, I review the ALS algorithm for Matrix Factorization with implicit feedback data and how we’ve scaled it up to handle 100s of Billions of data points using Scala, Breeze, and Spark.

Music Recommendations at Scale with Spark

Chris Johnson

Are you still building data pipelines with Java and Python? Are you curious about the current buzz in the Big Data community surrounding Scala as a data processing environment? In this talk I'll discuss how Spotify migrated its music recommendations pipeline from Python to Scala. I'll dive into the language specific features that make Scala the ideal candidate for big data processing as well as highlight the rich set of tools and APIs that we take advantage of to process music recommendations for our 50 Million active users including Scalding, Breeze, Kafka, Spark, Parquet, Driven and Zeppelin.

Scala Data Pipelines for Music Recommendations

Chris Johnson

Interactive recommender systems enable the user to steer the received recommendations in the desired direction through explicit interaction with the system. In the larger ecosystem of recommender systems used on a website, it is positioned between a lean-back recommendation experience and an active search for a specific piece of content. Besides this aspect, we will discuss several parts that are especially important for interactive recommender systems, including the following: design of the user interface and its tight integration with the algorithm in the back-end; computational efficiency of the recommender algorithm; as well as choosing the right balance between exploiting the feedback from the user as to provide relevant recommendations, and enabling the user to explore the catalog and steer the recommendations in the desired direction. In particular, we will explore the field of interactive video and music recommendations and their application at Netflix and Spotify. We outline some of the user-experiences built, and discuss the approaches followed to tackle the various aspects of interactive recommendations. We present our insights from user studies and A/B tests. The tutorial targets researchers and practitioners in the field of recommender systems, and will give the participants a unique opportunity to learn about the various aspects of interactive recommender systems in the video and music domain. The tutorial assumes familiarity with the common methods of recommender systems.

Discover Weekly is a personalized mixtape of 30 highly personalized songs that's curated and delivered to Spotify's 75M active users every Monday. It's received high acclaim in the press and reached 1B streams within its first 10 weeks. In this slide deck we dive into the narrative of how Discover Weekly came to be, highlighting technical challenges, data driven development, and the Machine Learning models used to power our recommendations engine.

Slides for my architectural session at the event: Docker From Zero To Hero. We talked about what kind of expertises are need in order to build a true Microservices Solution; you'll need to understand some of the fundamentals on which Microservices is built upon: SOA, EDA and DDD just to name a few, then you can move to the container world.

Finagle is an open-source, high-volume RPC client library, handling millions of QPS at companies like Twitter, Pinterest and Soundcloud. In this talk, we demonstrate how Finagle can be applied to Kubernetes applications via linkerd, an open-source, standalone Finagle proxy. By deploying linkerd as a sidecar container or with DaemonSets, we show how polyglot multi-service applications running in Kubernetes can be “wrapped” in Finagle’s operational model, adding connection pooling, load-balancing, failure detection, and failover mechanisms to existing applications with minimal code change. We demonstrate how linkerd communicates with the Kubernetes API and how the resulting systems perform under load and adverse conditions. Sched Link: http://sched.co/6BhW

AngularJS today is one of the most powerful, user-friendly and popular JS frameworks to work on web applications. Surprisingly, one of the main weaknesses of this framework is poorly structured documentation and the lack of ready-made solutions. In this report, we will try to work out the best approach to the organization of large and very large applications. We will also speak about the tools that will be useful at every stage of the application development and tools and practicesthat will help you to work in the continuous delivery mode.

The latest issue of Ericsson Technology Review includes articles that shed light on important topics including the evolution of LTE to fit the 5G future; an overview of the latest developments in microwave backhaul; and how DevOps can be used to satisfy demands for faster turnaround in feature development. It also contains our annual technology trends article, in which I present what I believe are the five trends to watch in our industry in the years ahead, namely: an adaptable technology base, the dawn of true machine intelligence, end-to-end security and identity for IoT, an extended-distributed IoT platform, and overlaying reality with knowledge. I hope you find the contents of this issue of the magazine as thought-provoking as I do. All of the articles included here are also available individually on our website. Please feel free to share them via e-mail or social media.

N-Grade deals with the maintenance of university, department, faculty, student information within the university. N-Grade is an automation system, which is used to store the department, faculty, student, courses and information of a university. Starting from registration of a new student in the university, it maintains all the details regarding the attendance and marks of the students. The project deals with retrieval of information through an INTRANET based campus wide portal. It collects related information from all the departments of an organization and maintains files, which are used to generate reports in various forms to measure individual and overall performance of the students.
