HoningDS.com offers data science training, with coding challenges, and real-time projects in Python and R.There are many institutes offering data science course in Hyderabad**,** you need to choose the one which gives you practical exposure. There will be 80% hands-on, and 20% theoretical concepts taught here. You will work with Kaggle datasets. By building a GitHub portfolio and by working with important packages like dplyr during interactive coding exercises, you will definitely get an edge over other aspirants.

## Highlights of this training that will blow your mind

I believe in learning by doing in my data science training classes , and trying out things. Imagine you are given a bunch of textbooks on a subject and asked to learn without any context. You get bored, right? This is where my data scientist course is unique. I provide 35 projects and coding challenges to work with. I describe the datasets and discuss the approach to find insights from them. We will implement the solution together during data science classes. I am sure you will agree that no other training institute in Ameerpet, Hyderabad comes even close to teaching hands-on knowledge to such an extent.

The first few days will be used to strengthen your fundamentals in various technologies.You will start with training in Python , R and SQL . We will work on projects after getting a reasonable understanding in these areas.In the recent past , Python has become the language of choice for data scientists.(https://www.kdnuggets.com/2018/05/poll-tools-analytics-data-science-machine-learning-results.html) . I expect this trend to continue, with increasing developments in it’s ecosystem.A common question that you may have is, how is this course different from other courses , like the John Hopkin data science course or the courses that institutes in Hyderabad offer.The main difference is , this educational programme is interactive.General educational platforms are not set up to do live hands on coding with real time datasets.The usual method of instruction** , **is to set up lessons in video or text or in a classroom , and the students learn in passive manner.As per a study , students who learned passively , were 1.5 times more likely to fail to reach their end goals. Hence , I ensure that you get hands on coding as part of my lectures**.**

## Projects covered in this course that gets you jobs

The first project covered during the lessons is Exploring Hacker News. We will then understand visualization using a College Majors dataset. For data cleaning and munging , we will use Star Wars Survey dataset (https://data.world/fivethirtyeight/star-wars-survey) . You get to build an analytics pipeline using spark ! I am sure you will agree with me that none of the courses in Hyderabad have such content . Note we also learn to build machine learning models using Car price prediction dataset (https://archive.ics.uci.edu/ml/datasets/automobile ) and many more.

## What is the demand for data scientists now ?

The demand for data scientists is huge. The reason is the demand vs supply gap. The salaries in this field are moving above $100,000 per year in the US. In India, there is an estimated shortage of about 200000 data scientists

If you want to become one of the lucky, well-compensated professionals filling the current gap in this field, then you should learn data science now. If you are thinking to learn data science in Hyderabad , make use of this opportunity right away.

## Who can learn data science and upskill themselves?

- Graduate students looking for a trending field to get into ( https://in.linkedin.com/jobs/data-scientist-jobs )

- If you are looking for a rigorous data science bootcamp

- IT professionals who want a change from legacy technologies

- Trainees with no knowledge of hadoop concepts

- If you want to attend an educational programme with experiential learning ( https://elearningindustry.com/project-based-learning-better-traditional-classroom )

- You want your learning to be immediately useful and job oriented.

Develop the latest skills in this field for a better future. The schedule will suit anyone with a commitment to learn.

## About the faculty

I am an IT professional with 15+ years of real-time experience.I have been working in the field of big data and data science for the last 5 years. I’ve bundled up my knowledge and started building Honing Data Science. My mission is to teach you the main concepts applied across the industry. I will train all of you with the skills needed to work in Data Science jobs, for a low price.

## The problem with classroom coaching

Have you been to institutes promising to teach you Data Science, but didn’t get a Data Scientist job due to lack of quality coaching? The reason is that you did not learn the real knowledge to get a Data Scientist job. Note that employers don’t care what courses you have done. Not every course in the market will teach you the concepts of mathematics, statistics, information science and computer science to make you capable of a career in business analytics.
