Feed: R-bloggers. Author: rOpenSci - open tools for open science. This week version 2.0 of the mongolite package has been released to CRAN. Major new features in this release include support for MongoDB 4.0, GridFS, running database commands, and connection pooling. Mongolite is primarily an easy-to-use client to get data in and out of MongoDB. However it supports increasingly many advanced features like aggregation, indexing, map-reduce, streaming, encryption, and enterprise authentication. The mongolite user manual provides a great introduction with details and worked examples. GridFS Support! New in version 2.0 is support for the MongoDB GridFS system. A GridFS is ... Read More

Feed: R-bloggers. Author: Mic. This is a short post following the previous one (PCA revisited). In this post I’m going to apply PCA to a toy problem: the classification of faces. Again I’ll be working on the Olivetti faces dataset. Please visit the previous post PCA revisited to read how to download it. The goal of this post is to fit a simple classification model to predict, given an image, the label to which it belongs. I’m goint to fit two support vector machine models and then compare their accuracy. The The first model uses as input data the raw ... Read More

Feed: R-bloggers. Author: insightr. By Gabriel Vasconcelos and Yuri Fonseca We are happy to introduce our new machine learning method called Boosting Smooth Trees (BooST) (full article here). This model was a joint work with professors Marcelo Medeiros and Álvaro Veiga. The BooST uses a different type of regression tree that allows us to estimate the derivatives of very general nonlinear models. In other words, the model is differentiable and it has an analytical solution. The consequence is that now we can estimate partial effects of a characteristic on the response variable, which provide us much more interpretation than traditional ... Read More

Feed: Planet MySQL; Author: Dimitri Kravtchuk; 2018-08-14 15:00 | MySQL, Performance, InnoDB, Benchmarks, Sysbench, IO-bound, Optane, DoubleWrite, Binlog This article is inspired by Percona blog post comparing MySQL 8.0 and Percona Server 5.7 on IO-bound workload with Intel Optane storage. There are several claims made by Vadim based on a single test case, which is simply unfair. So, I'll try to clarify this all based on more test results and more tech details.. But before we start, some intro : InnoDB Parallel Flushing -- was introduced with MySQL 5.7 (as a single-thread flushing could no more follow), and implemented as ... Read More

Feed: Liquid Web. Author: Jennifer Bourn; In a perfect world, every potential website client who contacts you about a new WordPress project would know exactly what they need, have a clear scope of work with a requirements list, and understand the costs associated with their request.But perfectly educated clients are rarely reality because they don’t build websites or work with WordPress for a living. They don’t spend all of their time learning about web design and web development. They aren’t experts in WordPress and shouldn’t be expected to become experts.Clients hire you because they are busy running their business and ... Read More

Feed: Planet MySQL; Author: Jesper Krogh; MySQL 8.0 introduced a new feature that allows you to persist configuration changes from inside MySQL. Previously you could execute SET GLOBAL to change the configuration at runtime, but you needed to update your MySQL configuration file in order to persist the change. In MySQL 8.0 you can skip the second step. This blog discuss how this works and how to backup and restore the configuration. Using SET PERSIST to set a variable and the persisted_variables table in the Performance Schema to get a list of persisted variables.Persisting Variables You persist changes with either ...
