Depending on what news headline you have read, you may have perceived an Artificial Intelligence (AI) system as either an Alexa or Siri assistant that understands all your commands, a deep learning system that can recognize dog or a cat from image, a system that recommends personalized medicine, or an intelligent, overpowering machine that can overtake all human tasks and render humans useless. Few of these definitions can be termed as visionary, few fear mongering and rest of them being evolutionary. Last month, I was at Artificial Intelligence (AI) Summit 2018 in San ... Read More

Convolutional neural network – In this article, we will explore our intuitive explanation of convolutional neural networks (CNNs) on high level. CNN are inspired by the structure of the brain but our focus will not be on neural science in here as we do not specialise in any biological aspect. We are going artificial in this post. Convolutional Neural Networks are a special kind of multi-layer neural networks. What are Convolutional Neural Networks Convolutional neural networks (CNN) –  Might look or appears like magic to many but in reality, its just ... Read More

Something I learned during my graduate studies is that jails – like the old Don Jail as it once existed in Toronto (photographed by me above) – has special significance among those that study the history of people with disabilities.  For one thing, there are many people with disabilities in jail – sometimes placed there because there isn’t a more suitable facility.  A person can receive care treatment in jail that is not available outside the correctional system.  On the other side of the coin, people are literally ...

Feed: R-bloggers. Author: arthur charpentier. Some pre-Halloween post today. It started actually while I was in Barcelona : kids wanted to go back to some store we’ve seen the first day, in the gothic part, and I could not remember where it was. And I said to myself that would be quite long to do all the street of the neighborhood. And I discovered that it was actually an old problem. In 1962, Meigu Guan was interested in a postman delivering mail to a number of streets such that the total distance walked by the postman was as short as ... Read More

Feed: R-bloggers. Author: R on Gianluca Baio. I have just submitted a revised version of survHE on CRAN — it should be up very shortly. This will be version 1.0.64 and its main feature is a major restructuring in the way the rstan/HMC stuff works. Basically, this is due to a change in the default C++ compiler. I don’t think much will change in terms of how survHE works when running full Bayesian models using HMC, but R now compiles it without problems. After the advice of Ben Goodrich, I have also modified the package so that it compiles the ... Read More

Feed: Big Data Made Simple. Author: Morgen Henderson. Teaching is a challenge. Instructors often teach a class of 30 or more students, making it difficult to give proper help and attention to each student. Every student learns at a different pace and in their own way. Many instructors use computer programs to allow students to work at a pace they find comfortable. However, these programs make it easy for students to “beat the system,” not truly learn. Students often develop an extrinsic attitude toward learning in this setting. They think, “what is the fastest and easiest way for me to ... Read More

Feed: MariaDB Knowledge Base Article Feed. Author: . ColumnStore is a columnar storage engine for MariaDB designed for big data, linear scaleability, and performance. It is included in the MariaDB AX distribution. ColumnStore is composed of User Modules that handle queries and Performance Modules that process, store and retrieve data. It can be installed on a single node or distributed across multiple nodes. Before attempting to install ColumnStore, you should first consider the architecture of your deployment. How many User Modules (UM) do you require? How many Performance Modules (PM) do you require? How much disk space do you require? ... Read More

Feed: MariaDB Knowledge Base Article Feed. Author: . Using binary tar installations, you can install MariaDB ColumnStore as a non-root user. This allows you to use non-default installation directories, which you may find convenient when using external storage. The specific user name is arbitrary. You can use whatever name you find most convenient. The examples below and elsewhere follow the MariaDB Server convention of using the mysql user and group. User Configuration In order to perform a non-root installation of ColumnStore, you first need to create the user and group. ColumnStore does not have any specifications on the name of ... Read More
