Intro to Apache Ignite: Distributed Framework for Unified In-memory Data Fabric - Abstract
An introduction to Apache Ignite™ (incubating), which is an open source, distributed framework for a unified In-Memory Data Fabric. Ignite provides a high-performance, distributed in-memory data management software layer that has been designed to operate between both new and existing data sources and applications, boosting application performance and scale by orders of magnitude. We will start with a summary of the technical drivers and market forces, and will cover popular and emerging use cases for in-memory computing, from financial industry trading platforms to mobile payment processing, online advertising, online/mobile gaming back-ends and more. We will then present some foundational concepts and terminology, and discuss the architecture, capabilities and benefits of the Ignite In-Memory Data Fabric in quite some detail.

Extending Word2Vec for Performance and Semi-supervised Learning - Abstract
MLLib Word2Vec is an unsupervised learning technique that can generate vectors of features that can then be clustered. But the weakness of unsupervised learning is that although it can say an apple is close to a banana, it can’t put the label of “fruit” on that group. We show how MLLib Word2Vec can be combined with the human-created data of YAGO2 (which is derived from the crowd-sourced Wikipedia metadata), along with the NLP metrics Levenshtein and Jaccard, to properly label categories. As an alternative to GraphX even though YAGO2 is a graph, we make use of Ankur Dave’s powerful IndexedRDD, which is slated for inclusion in Spark 1.3 or 1.4. IndexedRDD is also used in a second way: to further parallelize MLLib Word2Vec. The use case is labeling columns of unlabeled data uploaded to the Oracle Data Enrichment Cloud Service (ODECS) cloud app, which processes big data in the cloud.
