Data science.. Education of tomorrow
Let’s start by defining Data Science, Data Science can be characterized as a mix of arithmetic, business keenness, apparatuses, calculations, and machine learning strategies, all of which help us in discovering the concealed experiences or examples from crude information which can be of significant use in the arrangement of enormous business choices.
In this field, one deals with both organized and unorganized information. The calculations additionally include a prescient examination. Consequently, data science is about the present and future. That is, discovering the patterns dependent on authentic information which can be valuable for present choices, and discovering designs that can be demonstrated and can be utilized for forecasts to perceive what things might resemble later on.
Data Science is a combination of Statistics, Tools, and Business information. In this way, it becomes basic for a Data Scientist to have great information and comprehension of these.
Why Data Science?
I am writing on this topic today because I, myself am doing a course on this very topic and very well know its importance. So according to my experience and knowledge, Data Science is the future of our world. By each passing moment, companies are storing data in some form on another, and to do the same and manage that data properly, the need for data scientists is ever increasing. All kinds of firms like Finance, Marketing, and Retail, IT, or banking are looking for Data Scientists. So in the future, definitely it would be a very good carrier option. And that’s why we can say that Data Science is education for tomorrow. So now let’s see what all comes under Data Science.
Data Science consists of 3 parts mainly i.e., Machine learning, Big data, and Business Intelligence. Machine learning is an integral part of AI. It is a study of computer algorithms that improves automatically through experience and by the use of data. Big data gives significant bits of knowledge to clients that organizations can use to refine their marketing, advertising, and promotions to expand client commitment and change rates. Business intelligence is a very broad term that includes data mining, process analysis, performance benchmarking, and descriptive analysis.
And now let’s discuss the tools used in excelling in data science. First of all, we should have a great knowledge of the R language as it is used for data analysis. After that, we should also have an in-depth knowledge of python coding. MS Excel and Hadoop platforms are also essential needs to learn data science. Now let’s see the Data science lifecycle in detail and also a little about Data Science tools.
The Data Science Lifecycle
The data science lifecycle, also known as the data science pipeline, has five to sixteen (depending on whom you ask) overlapping continuous processes. The processes that almost all lifecycle definitions have in common are as follows:
- Collection: It is a group of structured and unstructured raw data from all relevant sources using almost any method, from manual input to web scraping and the collection of data from systems and devices in real-time.
- Prepare and Maintain: This part includes bringing the raw data into a consistent format for analysis or machine learning or deep learning models. This can include anything from cleaning, deduplication, and reformatting the data to using ETL (extract, transform, and load) or other data integration technologies to put the data into a data warehouse, Data Lake, or other unified storage for the combined analysis.
- Pre-processing or Processing: In this part, data scientists examine biases, patterns, ranges, and distributions of values within the data to determine the suitability of the data for use with predictive analytics, machine learning, and/or deep learning algorithms (or other analytical methods).
- Analytics: This is where discovery takes place, where data scientists perform statistical analysis, predictive analysis, regression, machine learning, and deep learning algorithms, and more to extract insights from prepared data.
- Communicate: Ultimately, information is presented in the form of reports, graphs, and other data visualizations that facilitate the understanding of the information, and its business impact, for decision-makers. A data science programming language like R or Python contains some components for generating visualizations; alternatively, data scientists can use dedicated visualization tools.
Data Science Tools
Data scientists must be able to write and execute code to create models. The most popular programming languages among data scientists are open source tools that contain or support out-of-the-box graphing, machine learning, and statistical functions. These languages include:
- R language: As an open-source programming language and environment for developing statistical calculations and graphs, R is the most popular programming language among data scientists. R language offers a variety of libraries and tools for cleaning and preparing data, creating visualizations, and training and evaluating machine learning and deep learning algorithms. It is also widely used among scientists and data science researchers.
- Python: Python is a universal, object-oriented, high-level programming language that emphasizes code readability with the help of its extensive use of spaces. Several Python libraries support data science tasks, including Numpy for handling large dimensional arrays, Pandas for data manipulation and analysis, and Matplotlib for creating data visualizations.
At last, I would like to say that we should have a knowledge of SQL language and coding also and should be updated about technology. This is all for right now but surely data science is a very interesting and wide topic. And there is a huge scope of data science in our future time.
