The Fifth Elephant 2015

A conference on data, machine learning, and distributed and parallel computing

Machine Learning, Distributed and Parallel Computing, and High-performance Computing are the themes for this year’s edition of Fifth Elephant.

The deadline for submitting a proposal is 15th June 2015

We are looking for talks and workshops from academics and practitioners who are in the business of making sense of data, big and small.

Track 1: Discovering Insights and Driving Decisions

This track is about general, novel, fundamental, and advanced techniques for making sense of data and driving decisions from data. This could encompass applications of the following ML paradigms:

  • Statistical Visualizations
  • Unsupervised Learning
  • Supervised Learning
  • Semi-Supervised Learning
  • Active Learning
  • Reinforcement Learning
  • Monte-carlo techniques and probabilistic programming
  • Deep Learning

Across various data modalities including multi-variate, text, speech, time series, images, video, transactions, etc.

Track 2: Speed at Scale

This track is about tools and processes for collecting, indexing, and processing vast amounts of data. The theme includes:

  • Distributed and Parallel Computing
  • Real Time Analytics and Stream Processing
  • MapReduce and Graph Computing frameworks
  • Kafka, Spark, Hadoop, MPI
  • Stories of parallelizing sequential programs
  • Cost/Security/Disaster Management of Data

Commitment to Open Source

HasGeek believes in open source as the binding force of our community. If you are describing a codebase for developers to work with, we’d like it to be available under a permissive open source license. If your software is commercially licensed or available under a combination of commercial and restrictive open source licenses (such as the various forms of the GPL), please consider picking up a sponsorship. We recognize that there are valid reasons for commercial licensing, but ask that you support us in return for giving you an audience. Your session will be marked on the schedule as a sponsored session.

Workshops

If you are interested in conducting a hands-on session on any of the topics falling under the themes of the two tracks described above, please submit a proposal under the workshops section. We also need you to tell us about your past experience in teaching and/or conducting workshops.

High Performance Tiled Map Service

Submitted Jun 15, 2015

To introduce the service behind the housing map interface and discuss the technical challenges and performance bottlenecks faced while developing the tiling map service.

Outline

Tiling service is the key service behind our map interface. It is responsible for smooth user interactions in dense inventory areas and, scaling our map interface. Our TMS(Tile Map service) faces the challenge of generating decluttered markers at real time for an unrestricted combination of filters and a rapidly changing inventory. The large number of filters restricts precomputation of tiles and frequent changes in inventory make it necessary to use a sophisticated caching mechanism. These conditions also make it impossible to have a client side overlay over Google Maps.

In this talk we’ll discuss the conditions that lead to creation of a dedicated maps service. We’ll also discuss the principal components of tiling service, such as, caching strategies, decluttering logic, real time image encoding techniques and the challenges we faced during their implementation.

Requirements

There are no requirements for this session.
