Written by Alexander Raginsky Big Data services offered in the cloud is nothing new. In the past years we have seen many Big Data vendors that have created Big Data solutions that can be accessed via the web to crunch and analyse your data. Recently however, we have seen the rise of a new type of offering: Big Data-as-a-Service

Written by Alexander Raginsky A pivot language is a third or intermediate language that can bridge the gap between language pairs. For example, if there are translations between English to French and the same English to Spanish available, through the pivot language English, translations between French and Spanish can be generated. The major drawback and concern of generated translations
Written by Alexander Raginsky Support vector machines (SVMs) use an approach based on constructing decision planes (lines). Such a plain (line) is built for separating objects belonging to different classes. Suppose we have two sets of objects: red and green ones. Sometimes it is possible to draw a line that separates red objects from green ones: See more at:
Written by Alexander Raginsky We’re living in a sea of information, bathing in a firehose of data from across our businesses. We know we need to use it, but the question is how? How can we get value from that information, and at the same time get ready for the faster, bigger, deeper streams that are going to come
Written by Alexander Raginsky Over the past few years, there have been talks about data management and administration of databases. It is indeed important for data to be managed properly for the best results. Businesses get to enjoy lots of benefits if they manage their data properly because data is an asset, and a very important one for that
Written by Alexander Raginsky In the near future, the following major trends are expected in Big Data analysis: Big Data technology will be based on a mixture of cloud and on-premises computing. Many corporations start migrating from in-house database infrastructures to cloud-based data warehouses. Distributed frameworks for data analytics like MapReduce are turning into distributed managers of resources and
Written by Alexander Raginsky Amazon.com is boosting its artificial-intelligence chops. The world’s largest retailer by market capitalization is rolling out its sophisticated big-data-crunching platform for developers in Europe, and is also hiring scientists for its research teams in New York and Berlin who specialize in getting machines to do things like make sales predictions and predict fraud. Machine learning
Written by Alexander Raginsky I signed up on Glassdoor to check salaries posted by data scientists, in various companies. Of course these numbers are subject to fraud (companies posting low salaries to drive salaries down, data scientists posting high salaries to drive salaries up), but so are most salary surveys. Even tax returns don’t tell the true story. I
Written by Alexander Raginsky Markov chain is a simple concept which can explain most complicated real time processes.Speech recognition, Text identifiers, Path recognition and many other Artificial intelligence tools use this simple principle called Markov chain in some form. In this article we will illustrate how easy it is to understand this concept.Introduction to Markov chain simplified Markov chain
