Feed: Featured Blog Posts - Data Science Central. Author: Divya Singh. Machine Learning is the word of the mouth for everyone involved in the analytics world. Gone are those days of the traditional manual approach of taking key business decisions. Machine Learning is the future and is here to stay. However, the term Machine Learning is not a new one. It was there since the advent of computers but has grown tremendously in the last decade due to the massive amounts of data that’s getting generated, and the enormous computational power that modern-day system possesses. Machine Learning is the art ... Read More

Feed: Featured Blog Posts - Data Science Central. Author: Andrea Manero-Bastin. This article was written by Will Koehrsen.  Reading through a data science book or taking a course, it can feel like you have the individual pieces, but don’t quite know how to put them together. Taking the next step and solving a complete machine learning problem can be daunting, but preserving and completing a first project will give you the confidence to tackle any data science problem. This series of articles will walk through a complete machine learning solution with a real-world dataset to let you see how all ... Read More

Feed: R-bloggers. Author: chris2016. Principal component analysis (PCA) is very useful for doing some basic quality control (e.g. looking for batch effects) and assessment of how the data is distributed (e.g. finding outliers). A straightforward way is to make your own wrapper function for prcomp and ggplot2, another way is to use the one that comes with M3C (https://bioconductor.org/packages/devel/bioc/html/M3C.html) or another package. M3C is a consensus clustering tool that makes some major modifications to the Monti et al. (2003) algorithm so that it behaves better, it also provides functions for data visualisation. Let’s have a go on an example cancer ... Read More

Feed: SAS Blogs. Author: Emily Gao. My colleague Wayne Thompson has written a series of blogs about machine learning best practices. In this series' fifth post, Autotune models to avoid local minimum breakdowns, Wayne discusses two autotune methods, grid search and Bayesian optimization. According to another colleague’s paper, Automated Hyperparameter Tuning for Effective Machine Learning, Bayesian optimization is currently popular for hyperparameter optimization. Recently, I read a post on Github which demonstrated the Bayesian optimization procedure through a great demo using Python, and I wondered if I could build the same with the SAS matrix language, SAS/IML. In this article, ... Read More

Feed: Recent Announcements. You can use the Ribbon SBC SWe to secure real-time communications, including unified communications, conferencing and collaboration, and contact center services, on AWS. The Ribbon SBC SWe provides robust interworking and normalization for multiple signaling and media protocols, call admission control to manage traffic levels, and multiple security features for both signaling and media to protect privacy and to help ensure regulatory compliance. The Quick Start is automated by AWS CloudFormation templates that deploy the Ribbon SBC SWe components into a new or existing virtual private cloud (VPC) in your AWS account. To get started: You can ... Read More

Feed: Planet PostgreSQL. If you’ve worked with Ruby on Rails you likely have some understanding of how your database works with Rails, traditionally that has always meant specifying a single database per environment in your config/database.yml, possibly together with an environment setting like DATABASE_URL. Based on that configuration all reads and writes will access the database. With Rails 6 this is about to change, thanks to the work of Eileen M. Uchitelle together with contributors from GitHub, Basecamp and Shopify. In the upcoming Rails 6 (currently in RC1), you will be able to easily change which database server you are ... Read More

Feed: R-bloggers. Author: rOpenSci - open tools for open science. We strive for high quality in our suite of packages, in practice via a system of software peer review, and via packaging guidelines that keep growing. There is therefore a risk of increasing the workload of package authors, who already have a lot on their plate. To avoid that, when explaining how to do things in our dev guide, we recommend existing automated tools to authors. The usethis package implements this important principle: Automate that which can be automated. Your computer was literally born to implement rote-but-fussy stuff for you ... Read More

Feed: Planet PostgreSQL. pg_cron is an interesting PostgreSQL extension by Citus Data: it does include a background worker (i.e., a PostgreSQL managed process) to execute database tasks on the server side. This is something I’ve done for years, I mean managing automated tasks using operating system wide cron(1) and schedulers alike, but having the scheduler within the database sounds really cool, since I can keep it tied to the data itself. An example scenario I’ve one server pulling data regularly out of another server, via a foreign data wrapper. No matter how this design choice sounds to you, it works ... Read More

Feed: Recent Announcements. The Marvell-based starter kits running Amazon FreeRTOS enable devices to easily and securely connect to AWS cloud services like AWS IoT Core or to edge devices running AWS IoT Greengrass. The respective starter kits include the MW320 / MW320 single chip Wi-Fi microcontroller System-on-Chip (SOC) and a fully-featured Cortex-M4 microcontroller. The SoC also enables easy interfacing to sensors, actuators, and other components via a full set of I/O interfaces including SPI, I2C, UART, I2S, PWM, ADC, DAC and GPIOs. You can get started by downloading Amazon FreeRTOS source code from GitHub and by using the tools below: ... Read More

Feed: AWS Compute Blog. Author: Nathan Taber. Contributed by Nathan Taber and Michael HausenblasAt re:Invent 2017 we introduced the Amazon Elastic Container Service for Kubernetes, or Amazon EKS for short. We consider these tenets as valid today as they were at launch: EKS is a platform to run production-grade workloads. This means that security and reliability are our first priority. After that we focus on doing the heavy lifting for you in the control plane, including life cycle-related things like version upgrades. EKS provides a native and upstream Kubernetes experience. This means, with EKS you get vanilla, un-forked Kubernetes. Of course, in ... Read More
