Data Science is used to apply critical analysis, provide the ability to develop sophisticated models, for massive data sets and drive business insights. Data Science utilizes the potential and scope of machine learning implementation, by making use of Mahout. **Data Science Training** in Pune with Data Interpretation for Business Intelligence

# Frequently asked questions

Two types: Descriptive(focuses on past data to understand past/present trends) and Predictive(focuses on past data to predict unknown/future)..

Data analyst generally works on creation of reports based on company’s data driven KPI’s(generally involves descriptive analytics), whereas Data scientists understand business and domain along with the technicalities to understand what will happen in future(more on descriptive + predictive analytics both)

Machine Learning algorithms are mathematical in nature, hence you need to first understand that part(includes statistics, probability theory, Linear Algebra).

Once you know this part, then in order to implement these algorithms on a real life data set, you need a language which contains modules which simplify ML development(like MATLAB, Python, R etc)

So, to sum it up:

-Maths

-Programming

-Data manipulation/preprocessing

-Machine Learning Algos

-Lots of scenarios

-End to End projects

-Deployment of Models on various cloud platforms.

Every person who has done some online course or has went through some tutorial uploads a CV for a JOB. But not necessary everyone gets it.

In order for you to get jobs, your skill level has to be detailed, your knowledge cannot be limited to generics. If you feel that by doing some sort of a crash course will get you anywhere, then I wish you luck.

By the time you have completed the course you should be able to handle complex scenarios with efficiency and measured approach(without any help of course).

So a simple advice: Join a detailed course.

The answer to this is relative based on your previous experience and technology. Kindly have a word with our technical counsellor regarding the same.

The term Data Science is used interchangeably with Datalogy.

Data Science employs its theories and techniques from physics, mathematics, nanotechnologies and this list goes to 23 fields.

Data Science is considered to be a part of many academic and research areas.

Data Science has been employed in fraud monitoring and security.

Data Analytics is now increasingly used in multiple sectors and these sectors owe their success to Data Science and Data Analytics

Various companies have certifications available for these kind of programs:

AWS Certified Machine Learning – Specialty certification

Professional Data Engineer Certification(Google)

Google Data Analytics Professional Certificate

Microsoft Certified: Azure Data Scientist Associate

Data science professionals(IBM)

and the list goes on.

Graduation in any stream, Freshers or working professionals who either wish to start their career as a Data Scientist or wish to switch from their previous profile into mainstream analytics.
