Revolution R Enterprise 6.1 README
Revolution R Enterprise 6.1 README Revolution R Enterprise 6.1 for 32-bit and 64-bit Windows and 64-bit Red Hat Enterprise Linux (RHEL 5.x and RHEL 6.x) features an updated release of the RevoScaleR package that provides fast, scalable data management and data analysis: the same code scales from data frames to local, high-performance .xdf files to data distributed across a Windows HPC Server cluster, Windows HPC Server Azure Burst cluster, or IBM Platform Computing LSF cluster. RevoScaleR also allows distribution of the execution of essentially any R function across cores and nodes, delivering the results back to the user. Installation instructions and instructions for getting started are provided in your confirmation e-mail. What’s New in Revolution R Enterprise 6.1 Big Data Decision Tree Models New RevoScaleR function rxDTree can be used to create decision tree models. It is based on a binning algorithm so that it can scale to huge data. Both classification and regression trees are supported. The model objects returned can be made to inherit from the rpart class of the rpart package, so that plot.rpart, text.rpart, and printcp can be used for subsequent analysis. Prediction for models fitted by rxDTree can be done using rxPredict. See Chapter 10 of the RevoScaleR User’s Guide for examples on how to create decision tree models with rxDTree. Additional information is available in the rxDTree help file, seen by entering ?rxDTree at the R command line. Support for Compression in .xdf Files RevoScaleR’s .xdf files can now be created using zlib compression. -

Machine Learning Is Driving an Innovation Wave in Saas Software
Machine Learning is Driving an Innovation Wave in SaaS Software By Jeff Houston, CFA [email protected] | 512.364.2258 SaaS software vendors are enhancing their soluti ons with machine learning (ML) algorithms. ML is the ability of a computer to either automate or recommend appropriate actions by applying probability to data with a feedback loop that enables learning. We view ML as a subset of artificial intelligence (AI), which represents a broad collection of tools that include/leverage ML, such as natural language processing (NLP), self-driving cars, and robotics as well as some that are tangent to ML, such as logical rule-based algorithms. Although there have been multiple “AI Winters” since the 1950s where hype cycles were followed by a dearth of funding, ML is now an enduring innovation driver, in our opinion, due in part to the increasing ubiquity of affordable cloud-based processing power, data storage—we expect the pace of breakthroughs to accelerate. automation, customer support, marketing, and human resources) through both organic and M&A These innovations will make it easier for companies initiatives. As for vertical-specific solutions, we think to benefit beyond what is available with traditional that a new crop of vendors will embrace ML and business intelligence (BI) solutions, like IBM/ achieve billion-dollar valuations. VCs are making big Cognos and Tableau, that simply describe what bets that these hypotheses will come to fruition as happened in the past. New ML solutions are demonstrated by the $5B they poured into 550 amplifying intelligence while enabling consistent and startups using AI as a core part of their solution in better-informed reasoning, behaving as thought 20162. -

Iotools: High-Performance I/O Tools for R by Taylor Arnold, Michael J
CONTRIBUTED RESEARCH ARTICLE 6 iotools: High-Performance I/O Tools for R by Taylor Arnold, Michael J. Kane, and Simon Urbanek Abstract The iotools package provides a set of tools for input and output intensive data processing in R. The functions chunk.apply and read.chunk are supplied to allow for iteratively loading contiguous blocks of data into memory as raw vectors. These raw vectors can then be efficiently converted into matrices and data frames with the iotools functions mstrsplit and dstrsplit. These functions minimize copying of data and avoid the use of intermediate strings in order to drastically improve performance. Finally, we also provide read.csv.raw to allow users to read an entire dataset into memory with the same efficient parsing code. In this paper, we present these functions through a set of examples with an emphasis on the flexibility provided by chunk-wise operations. We provide benchmarks comparing the speed of read.csv.raw to data loading functions provided in base R and other contributed packages. Introduction When processing large datasets, specifically those too large to fit into memory, the performance bottleneck is often getting data from the hard-drive into the format required by the programming environment. The associated latency comes from a combination of two sources. First, there is hardware latency from moving data from the hard-drive to RAM. This is especially the case with “spinning” disk drives, which can have throughput speeds several orders of magnitude less than those of RAM. Hardware approaches for addressing latency have been an active area of research and development since hard-drives have existed. -

REVOLUTION ANALYTICS = ACTUARIAL EYE (Part 1)
REVOLUTION ANALYTICS = ACTUARIAL EYE (Part 1) “Perhaps the most important cultural trend today: The explosion of data about every aspect of our world and the rise of applied math gurus who know how to use it.” – Chris Anderson, editor-in-chief of Wired. “There is a real appetite in the business to understand more and to think about how we assemble and use data, also making sure we have the right people to ask the right questions of the data – because one without the other is not helpful.” - Wendy Thorpe, AMP Why Analytics? Organizations are built on great decisions and great decisions are built on great predictions. So what are great predictions built on? The answer is ANALYTICS!!! So in case you are wondering what this could possibly mean for you as a prospective actuary, the answer depends on what kind of actuary you want to be. Let me quote Duncan West here: If you are in a leadership role in your organization, get data onto the strategic agenda. Many companies talk about the importance of data but talk is not cheap. Do they manage themselves in ways that demonstrates the importance? Actuaries in any role need to go away from a regulatory and compliance mindset that accuracy is the most important way to measure success. They should measure success by helping the business to make good decisions. And actuaries at all levels need to help develop the skills necessary to show insights to the business. Insights are useless if the business can’t understand them. So communicating insight is a key part of an actuarial role. -

Mergers in the Digital Economy
2020/01 DP Axel Gautier and Joe Lamesch Mergers in the digital economy CORE Voie du Roman Pays 34, L1.03.01 B-1348 Louvain-la-Neuve Tel (32 10) 47 43 04 Email: [email protected] https://uclouvain.be/en/research-institutes/ lidam/core/discussion-papers.html Mergers in the Digital Economy∗ Axel Gautier y& Joe Lamesch z January 13, 2020 Abstract Over the period 2015-2017, the five giant technologically leading firms, Google, Amazon, Facebook, Amazon and Microsoft (GAFAM) acquired 175 companies, from small start-ups to billion dollar deals. By investigating this intense M&A, this paper ambitions a better understanding of the Big Five's strategies. To do so, we identify 6 different user groups gravitating around these multi-sided companies along with each company's most important market segments. We then track their mergers and acquisitions and match them with the segments. This exercise shows that these five firms use M&A activity mostly to strengthen their core market segments but rarely to expand their activities into new ones. Furthermore, most of the acquired products are shut down post acquisition, which suggests that GAFAM mainly acquire firm’s assets (functionality, technology, talent or IP) to integrate them in their ecosystem rather than the products and users themselves. For these tech giants, therefore, acquisition appears to be a substitute for in-house R&D. Finally, from our check for possible "killer acquisitions", it appears that just a single one in our sample could potentially be qualified as such. Keywords: Mergers, GAFAM, platform, digital markets, competition policy, killer acquisition JEL Codes: D43, K21, L40, L86, G34 ∗The authors would like to thank M.
