Azure Data Lake Store

Azure Data Lake Store (ADLS) is a fully managed, elastic, scalable, and secure file system that supports semantics of the Hadoop distributed file system (HDFS) and the Microsoft Cosmos file system. It is specifically designed and optimized for a broad spectrum of big data analytics that depend on an extremely high degree of parallel reads and writes, as well as colocation of compute and data for high-bandwidth and low-latency access. It brings together key components and features of Cosmos — long used internally at Microsoft as the warehouse for data and analytics — and HDFS. It also is a unified file storage solution for analytics on Azure. Internal and external workloads run on this unified platform. Distinguishing aspects of ADLS include its support for multiple storage tiers, exabyte scale, and comprehensive security and data sharing. Raghu Ramakrishnan will cover ADLS architecture, design points, the Cosmos experience, and performance.

MACHINE LEARNING: Building data-efficient AI algorithms with a dose of inspiration from the brain

Currently, the predominant approach in AI is to use unlimited data to solve narrowly defined problems. To progress toward humanlike intelligence, AI benchmarks will need to be extended to focus more on data efficiency, flexibility of reasoning, and transfer of knowledge between tasks. This talk will detail the challenges and successes in making these ideas operational. At Vicarious, the language of probabilistic graphical models is used as the representational framework. Compared with neural networks, graphical models have several advantages, such as the ability to incorporate prior knowledge, answer arbitrary probabilistic queries, and deal with uncertainty. However, a downside is that inference can be intractable. By incorporating several insights that originally were discovered in neuroscience, engineers at Vicarious were able to create probabilistic models, on which accurate inference can be performed using message-passing algorithms that are similar to the computations in a neural network.
