Large-Scale Learning from Data Streams with Apache SAMOA
Large-Scale Learning from Data Streams with Apache SAMOA Nicolas Kourtellis1, Gianmarco De Francisci Morales2, and Albert Bifet3 1 Telefonica Research, Spain, [email protected] 2 Qatar Computing Research Institute, Qatar, [email protected] 3 LTCI, Télécom ParisTech, France, [email protected] Abstract. Apache SAMOA (Scalable Advanced Massive Online Anal- ysis) is an open-source platform for mining big data streams. Big data is defined as datasets whose size is beyond the ability of typical soft- ware tools to capture, store, manage, and analyze, due to the time and memory complexity. Apache SAMOA provides a collection of dis- tributed streaming algorithms for the most common data mining and machine learning tasks such as classification, clustering, and regression, as well as programming abstractions to develop new algorithms. It fea- tures a pluggable architecture that allows it to run on several distributed stream processing engines such as Apache Flink, Apache Storm, and Apache Samza. Apache SAMOA is written in Java and is available at https://samoa.incubator.apache.org under the Apache Software Li- cense version 2.0. 1 Introduction Big data are “data whose characteristics force us to look beyond the traditional methods that are prevalent at the time” [18]. For instance, social media are one of the largest and most dynamic sources of data. These data are not only very large due to their fine grain, but also being produced continuously. Furthermore, such data are nowadays produced by users in different environments and via a multitude of devices. For these reasons, data from social media and ubiquitous environments are perfect examples of the challenges posed by big data. -

Commercial Hadoop support is available from large enterprises, like EMC, IBM, Microsoft and Oracle and Hadoop companies like Cloudera, Hortonworks, and Map Reduce. Hadoop is a scheme written in Java that allows distributed processes of large data sets across clusters of computers using programming models. A Hadoop frame work application works in an environment that provides storage and computation across clusters of computers. -

Annex 2: List of tested and analyzed data sharing tools (non-exhaustive) Below are the specifications of the tools surveyed, as to February 2015, with some updates from April 2016. The tools selected in the context of EU BON are available in the main text of the publication and are described in more details. This list is also available on the EU BON Helpdesk website, where it will be regularly updated as needed. Additional lists are available through the GBIF resources page, the DataONE software tools catalogue, the BioVel BiodiversityCatalogue and the BDTracker A.1 GBIF Integrated Publishing Toolkit (IPT) Main usage, purpose, selected examples The Integrated Publishing Toolkit is a free open source software tool written in Java which is used to publish and share biodiversity data sets and metadata through the GBIF network. Designed for interoperability, it enables the publishing of content in databases or text files using open standards, namely, the Darwin Core and the Ecological Metadata Language. It also provides a 'one-click' service to convert data set metadata into a draft data paper manuscript for submission to a peer-reviewed journal. Currently, the IPT supports three core types of data: checklists, occurrence datasets and sample based data (plus datasets at metadata level only). The IPT is a community-driven tool. Core development happens at the GBIF Secretariat but the coding, documentation, and internationalization are a community effort. New versions incorporate the feedback from the people who actually use the IPT. In this way, users can help get the features they want by becoming involved. The user interface of the IPT has so far been translated into six languages: English, French, Spanish, Traditional Chinese, Brazilian Portuguese, Japanese (Robertson et al, 2014). -

A Comprehensive Study of Bloated Dependencies in the Maven Ecosystem
Noname manuscript No. (will be inserted by the editor) A Comprehensive Study of Bloated Dependencies in the Maven Ecosystem César Soto-Valero · Nicolas Harrand · Martin Monperrus · Benoit Baudry Received: date / Accepted: date Abstract Build automation tools and package managers have a profound influence on software development. They facilitate the reuse of third-party libraries, support a clear separation between the application’s code and its ex- ternal dependencies, and automate several software development tasks. How- ever, the wide adoption of these tools introduces new challenges related to dependency management. In this paper, we propose an original study of one such challenge: the emergence of bloated dependencies. Bloated dependencies are libraries that the build tool packages with the application’s compiled code but that are actually not necessary to build and run the application. This phenomenon artificially grows the size of the built binary and increases maintenance effort. We propose a tool, called DepClean, to analyze the presence of bloated dependencies in Maven artifacts. We ana- lyze 9; 639 Java artifacts hosted on Maven Central, which include a total of 723; 444 dependency relationships. Our key result is that 75:1% of the analyzed dependency relationships are bloated. In other words, it is feasible to reduce the number of dependencies of Maven artifacts up to 1=4 of its current count. We also perform a qualitative study with 30 notable open-source projects. Our results indicate that developers pay attention to their dependencies and are willing to remove bloated dependencies: 18/21 answered pull requests were accepted and merged by developers, removing 131 dependencies in total. -
Is 'Distributed' Worth It? Benchmarking Apache Spark with Mesos
Is `Distributed' worth it? Benchmarking Apache Spark with Mesos N. Satra (ns532) January 13, 2015 Abstract A lot of research focus lately has been on building bigger dis- tributed systems to handle `Big Data' problems. This paper exam- ines whether typical problems for web-scale companies really benefits from the parallelism offered by these systems, or can be handled by a single machine without synchronisation overheads. Repeated runs of a movie review sentiment analysis task in Apache Spark were carried out using Apache Mesos and Mesosphere, on Google Compute Engine clusters of various sizes. Only a marginal improvement in run-time was observed on a distributed system as opposed to a single node. 1 Introduction Research in high performance computing and `big data' has recently focussed on distributed computing. The reason is three-pronged: • The rapidly decreasing cost of commodity machines, compared to the slower decline in prices of high performance or supercomputers. • The availability of cloud environments like Amazon EC2 or Google Compute Engine that let users access large numbers of computers on- demand, without upfront investment. • The development of frameworks and tools that provide easy-to-use id- ioms for distributed computing and managing such large clusters of machines. Large corporations like Google or Yahoo are working on petabyte-scale problems which simply can't be handled by single computers [9]. However, 1 smaller companies and research teams with much more manageable sizes of data have jumped on the bandwagon, using the tools built by the larger com- panies, without always analysing the performance tradeoffs. It has reached the stage where researchers are suggesting using the same MapReduce idiom hammer on all problems, whether they are nails or not [7].
