[wilibrodussmitshambur]

Through this article I can finally understand the basic concepts of data scientists. Thank you for sharing the knowledge.

[doctordodo]

Thank you very much. I was in the ERP and CRM in the late '90s and early 2000s and then left the industry for personal reasons. And I am now trying to get back into the Data Science and was all confused about the whole thing. But your explanation between Business Intelligence and Data Science has truly helped me to understand the whole thing now. Thank you very much. You have given me back the confidence in the knowledge that I have already had sitting there.

[degalasubbaramaiah]

Excellent tutorial. Dsubbaramaiah I will continue to learn data science to apply this to the Judiciary where the pending cases are mounting to 33 million and the Judiciary is caught unawares to find solution.

Thanks a lot . I have a quick question here to choose whether to proceed with R or Python ? I have fair good idea about, Java, Python, SAP ERP, HANA ( DB ) and ETL concepts + Statistical analysis. Where do you se the future ? Python or R ?

[prasanthipaleti]

Excellent presentation about Data Thank you somuch

[hemanthsr]

Great introduction to data science
Thank you simplilearn

[izooplaindia]

Great presentation, appreciate if you could use the neural network model building in brief and limitations on such models will certainly ignites the students curiosity for how does these models are built, how these can be tweaked or enhanced to to get better accuracy.

[sonshinetv]

Am so enthusiastic to hear this.Thank you

[Sarajshares]

Love the way you are explaining and i understand the concept clearly, thankyou

[architaanand]

Its a wonderful and an insightful video. Im a monitoring and evaluation officer with a humanities background. Im keen to learn Data Analysis but with no solid foundation in Maths, I’ve always shied away from the thought. Please guide me about the first step that I should be taking in order to learn Data Analysis.
