This post is the 3rd post in a series on how to use the R package ggplot2 to create data visualizations, but before delving into R code here comes a little confession.
For a couple of years (decades) I’m an avid user of the SQL Server Data Platform, spanning of course the relational database engine designing and implementing DWHs, but also building analytical applications using MS SQL Server Analysis Services Multidimensional and Tabular. But for a couple of reasons I never get along with the Reporting Services as a platform for Business Intelligence solutions on top of the data stores. With the upcoming release of SQL Server 2016 and Microsoft’s BI strategy (disclosed at the PASS Summit 2015) this will change dramatically. Due to the fact that Microsoft is moving with an unbelievable pace, this post will become somewhat lengthy. Please be aware, that whenever I mention SQL Server or Reporting Services.

Introduction to Genetic Algorithms in C# Posted on Tuesday May 14, 2013 Get the code A long time ago I mentioned in this post that I was planning on writing up some notes I made at university about Genetic Algorithms (from now on, known as GAs) and my version of a very simple example in C#.
Years later…here it is! C# isn’t the most popular choice for artificial or natural intelligence programming, that job is largely the domain of Java or other more academic friendly languages. This means there aren’t a great deal of C# examples out there for neural networks, search and genetic algorithms and programming. I’m going for the keep it simple stupid approach, sticking to bit strings for each gene.
The basis of the information here is from the original 1970s book “Adaptation in Natural and Artificial Systems” by John Henry Holland, which is how I was taught it at University a few years ago. A brief introduction to genetics Each of these genes in turn contains a sequence of DNA. The lifetime of the species is a single generation. Revolutions. R - Installing of SparkR. MongoDB – State of the R. Naturally there are two reasons for why you need to access MongoDB from R: MongoDB is already used for whatever reason and you want to analyze the data stored therein You decide you want store your data in MongoDB instead of using native R technology like data.table or data.frame In-memory data storage like data.table is very fast especially for numerical data, provided the data actually fits into your RAM – but even then MongoDB comes along with a bag of goodies making it a tempting choice for a number of use cases: Flexible schema-less data structures spatial and textual indexing spatial queries persistence of data easily accessible from other languages and systems In case you would like to learn more about MongoDB then I have good news for you – MongoDB Inc. provides a number of very well made online courses catering to various languages.
