Video: 3 Big Data Tech Talks You Can’t Miss

September 19, 2011

Sharing knowledge is part of our core culture at LinkedIn, whether through hackdays or contributions to open-source projects. We actively participate in both academic conferences, such as KDD, SIGIR, and WWW, and industry conferences such as OSCON and Strata.

A few months ago, we decided to take knowledge sharing a step further by launching an Open Tech Talk series, hosted at our Mountain View headquarters and open to the general public. Here are three of my favorite big-data tech talks that we’ve hosted at LinkedIn thus far:

1. Mining Billion-Node Graphs by Christos Faloutsos (Carnegie Mellon University)

What do graphs look like? How do they evolve over time? How do you handle a graph with a billion nodes? Christos presents a comprehensive list of static and temporal laws, grounded in recent observations on real graphs. He then presents tools for discovering anomalies and patterns in graphs. Finally, an overview of the PEGASUS system which is designed to handle billion-node graphs using Hadoop.

2. Recommender Systems: The Art and Science of Matching Items to Users by Deepak Agarwal (Yahoo! Research)

Algorithmically matching items to users in a given context is essential for the success and profitability of large scale recommender systems like content optimization, computational advertising, search, shopping, movie recommendation, and many more. In this talk, Deepak discusses some of the key technical challenges by focusing on a concrete application – content optimization on the Yahoo! front page. He also briefly discusses response prediction techniques for serving ads on the RightMedia Ad exchange.

3. Big Data in Real Time: Processing Data Streams at LinkedIn by Jay Kreps (LinkedIn)

My colleague, Jay Kreps, discusses the state of up-and-coming stream processing technologies and how they fit in the broader data infrastructure ecosystem — from live storage systems to Hadoop. He explores problems that are amenable to real-time stream processing, solutions that change and shape the way we think about data, and challenges and lessons that we have learned while building LinkedIn’s data infrastructure. A must-see presentation.

In addition to providing compelling speakers, Open Tech Talks offer attendees food, drinks, and a low-pressure environment in which people with shared professional interests can reconnect with people they know, as well as making new connections. For those who cannot attend, we live-stream the talks and post the recordings on YouTube.

We, at LinkedIn, are proud to be able to do our part to share this knowledge with the engineering community, and we hope you’ll join us for our future Open Tech Talks.
