Skills required during Interviews for a Data Scientist @ Facebook, Intel, Ebay. Square etc.
 

Basic Programming Languages: You should know a statistical programming language, like R or Python (along with Numpy and Pandas Libraries), and a database querying language like SQL

Statistics: You should be able to explain phrases like null hypothesis, P-value, maximum likelihood estimators and confidence intervals. Statistics is important to crunch data and to pick out the most important figures out of a huge dataset. This is critical in the decision-making process and to design experiments.

How Predictive Analysis Could Have Saved the World from Ransomware

How Predictive Analysis Could Have Saved the World from Ransomware
 

Kudos to you, if you have stayed offline for the last couple of days, so you could actually spend the weekend well with your family and loved ones. The world is reeling under the shattering news surrounding WannaCry Ransomware this weekend. The situation was worse on Monday, after the offices opened. Going by the figures, revealed out on Monday evening by Elliptic, a Bitcoin forensics firm, which is keeping a watch overall – $57,282.23 in ransom has been shelled out to the hackers of Ransomware malware attack, who took over hundreds and thousands of computers worldwide on Friday and through the weekend.

The Most Important Algorithms Every Data Scientist Must Know

Algorithms are now like the air we breathe; it has become an inevitable part of our daily lives and is also included in all types of businesses. Experts like Gartner has called this age as the algorithm business which is the key driving force that is overthrowing the traditional ways in which we do our business and manage operations.

 

The most important algorithms of machine learning

 

In fact the algorithm boom with uber diversification has reached a new high, so much so that now each function in a business has its own algorithm and one can buy their own from the algorithm marketplace. This was developed by algorithm developers at Algorithmia to save the precious time and money of business operators and other fellow developers and offers a plethora of more than 800 algorithms in the fields of machine learning, audio and visual processing and computer vision.

The Limitation of R Programming

R Programming is sort of the darling of the academia and researchers as well due to the cutting edge tools of data science and analytics that it offers. Not only does its open source nature ensure that contributors to the project are able to come out with packages that facilitates in making R Programming be able to sport the latest advances in its field but also make it a option that may be implemented with burning a hole in ones pockets.

 

The Limitation of R Programming

The Disadvantages of R

In spite of all its flexibility, R is found want in a number of specific situations. R cannot scale properly with large sets of data. There have been a number of efforts to overcome this significant disadvantage of R, but these efforts have not met with much success and the bottleneck remains an issue which needs to be dealt with seriously.
