AI, BigData &HPC Digest #3

1 year, 5 months ago


Hi, Habr!

Our FlyElephant command wants to congratulate all with coming New Year, to wish all the best and successful implementation of all conceived projects forthcoming year and that at the weekend was what to esteem, we publish fresh number of the digest. Today in release a traditional selection of interesting links on news and materials in the directions: artificial intelligence, big data and high-performance calculations.

On January 14th we will hold a webinar on Introduction to machine learning"" on which we will talk about history and the basic concepts of machine learning. Let's consider popular problems / algorithms of machine learning, and also we will start their examples by means of FlyElephantthe platform and we learn as it is possible to use this platform for a solution of problems of artificial intelligence. It is possible to be registered on a webinar here.

Festival of Data in the museum of Moscow as it was

1 year, 5 months ago


Hi Habr,

So, we held the Festival of the new technologies Given at an exhibition here.

And we tell this first action from a series in which we bring together experts from different areas of business, science and public administration about analytics of data.

Storage and data analysis which were a prerogative of a narrow circle of the companies and people now begin to affect life practically all. For this reason we also began this series of actions where we tell wide audience about data and their analytics.

Issue. Where? When? R

imageWhile behind a window temperature on the way to the next records, it is interesting to look and what in general there were temperatures in any interval, for any years for the last several decades in 30 000 points worldwide. And can not lose with days of issue and take them those days when there is some "statistical benefit" in the selected location on warm weather, and can be on cold, having estimated it visually on any of three types of charts. Well or it is possible just to rotate the globe, to visually evaluate a variety of temperatures and "as this world is beautiful".

Festival of data in the museum of Moscow or as Big Data helps to live and work

1 year, 6 months ago


Hi Habr,

If long ago it was interesting to you how Big Data is applied in different areas of business, science and public administration and it there was a wish to hear from people who are engaged in it, then welcome to the Festival of Data which will take place on December 19 at the Exhibition of the High SMIT Technologies in the Museum of Moscow.

During several business hours of the Festival leading experts of the industry from Yandex, "Schools of data Beeline", Data-Centric Alliance, Avito, state unitary enterprise "NI and PI of the General plan of Moscow, Higher School of Economics National Research University will tell guests of an exhibition about perspectives of use of data analysis in the next several years.

Data Science Skills

1 year, 6 months ago


We continue a series of analytical researches of a demand of skills in labor market. This time thanks to Pavel Surmenk of sharky we will consider a new profession – Data Scientist.

The last years the term Data Science began to gain popularity. Write about it much, speak at conferences. Some companies even employ people to a position with the sonorous name Data Scientist. What is Data Science? And who such Data Scientists?

Find the corrupt official. Data analysis of officials from projects of Clerical one hundred (with examples on R)

1 year, 7 months ago
How to define officials, the most suspicious from the point of view of corruption? Simplest — having compared their income and standard of living.

I want to show possibilities of the websites with open information on officials in this article, to look at how these officials live and to try to define those who are most suspicious from the point of view of corruption.

Why open information on the income of officials is important? Because it allows to control them.

swirl: prompt immersion in R (learning by doing)

1 year, 7 months ago


Still some one and a half years ago I was one of those who with conviction said "No, programming is definitely not for me". I will not risk to tell that I became a programmer, but for the last year R replaced to me the majority of daily programs for work. I work as the researcher. With interest I observe how gradually R becomes the standard in the academic world. Generally, in the world the understanding that it makes sense to communicate with the computer slightly more freely, than at the level of the click&drag programs spreads.; So, quite recently the Jellyfish wrote that not everything proger virgins programming should be studied to much more wide range of people, than was always considered to be.

In this post I will tell about one of the shortest ways to programming — studying of R by means of a special packet of swirl (the packet in R is the same that in many other languages is called library, expansion/addition of initial functionality). The post is expected the reader with zero knowledge of R interested in studying of this programming language; it will help as it seems to me, most effectively and without serious consequences to take the first steps in a programming dark.

Why R?
Short answer: because only I can share it, I do not know other programming languages.

The unrolled answer: R — a versatile tool which can be useful to very wide range of specialists. It is completely open and very dynamically developing project with a lot of inspired followers worldwide. Everyone can write the packet and lay out in open access (it really not really difficult). R gives boundless opportunities for data visualization. To be inspired, it is possible to glance in one of galleries (for example, this post.

On Habré there are a lot of publications with use of R. There are also posts about the language, for example R crib. Is possible to subtract a lot of curious from the text of the person who found R nearly at the sources.

For the researcher of R is just must.

Visualization of static and dynamic networks on R, part 7, the last

1 year, 7 months ago
In the first part:
  • visualization of networks: what for? how?
  • visualization parameters
  • best practices — an esthetics and performance
  • formats of data and preparation
  • the description of data sets which are used in examples
  • beginning of work with igraph

In the second part: colors and fonts in diagrams R.

In the third part: parameters of graphs, tops and edges.

In the fourth part: placements of a network.

In the fifth part: emphasis of properties of a network, tops, edges, ways.

In the sixth part: interactive visualization of networks, other methods of representation of a network.

In this part: the animated visualization of networks, evolution of a network in time.

AI, BigData &HPC Digest #2

1 year, 8 months ago
Hi, Habr!

After short break, our FlyElephant team renews the publication of the digest including selection of links to news and materials in the directions: artificial intelligence, big data and high-performance calculations. Also we now conduct survey among scientists in which we ask to answer couple of questions of carrying out researches connected with their process. We will be grateful to all for participation in poll and pleasant reading materials of the fresh digest!
