It doesn’t matter whether you are using R or Python or Weka – the best approach to learn data science is to learn the basics of the tool you are using (e.g. How is data stored? How can you access specific data points? How to make data manipulations? etc.) and then just start working on a data science problem / project.
Data visualization simply means the creation and analysis of data represented visually. Data abstraction and representation is done in various forms with several attributes and variables serving as units of information.
There are myriad of free Data Visualization Tools available over Internet, amongst them we have compiled a list of 20 Free Data Visualization Tools to serve your purpose, following tools allow end user to view all types of data and to better understand this data provided within a visually defined manner – and this is the definitive purpose
A conditional probability is the probability of an event, given some other event has already occurred. In the below example, there are two possible events that can occur. A ball falling could either hit the red shelf (we'll call this event A) or hit the blue shelf (we'll call this event B) or both.
If we know the statistics of these events across the entire population and then were to be given a single ball and told "this ball hit thered shelf (event A), what's the probability it also hit the blue shelf (event B)?" we could answer this question by providing the conditional probability of B given that A occurred or P(B|A).
Vital personal and business information flows over the Internet more frequently than ever, and we don't always know when it's happening. It's clear at this point that encrypting is something all of us should be doing. Then why don’t we use TLS (the successor to SSL) everywhere? Every browser in every device supports it. Every server in every data center supports it. Why don’t we just flip the switch?
Python is amazing. Created to be general-purpose, high-level programming language. Python is a "fun to use" language, named after Monty Python’s Flying Circus. Combines "remarkable power with very clear syntax" and provides a large and comprehensive standard library. The "standard library" is a collection of code already written and directly available to you. That’s a good thing: it means people have written code for most applications you could be thinking of. multi-paradigm programming language permitting several styles: object-oriented, structured,functional and aspect-oriented. Application domains: web development, database access, desktop GUIs, education, scientific and numeric computing, network programming, game and 3D graphics. "Python has been an important part of Google since the beginning, and remains so as the system grows and evolves. Today dozens of Google engineers use Python, and we're looking for more people with skills in this language." Peter Norvig, Director at Google, Inc.
