Posted in Programming   OCTOBER 12, 2021

Data Science

Organizations daily deal with zettabytes and yottabytes of organized and unstructured data in an increasingly digital environment. Cost reductions and better storage areas for vital data have been enabled by evolving technology. Now, businesses may examine this data to get a better understanding of global market trends and improve their business's chances of success. Additionally, data science can forecast future occurrences using both current and historical data.

What is Data Science?

Data Science is a multidisciplinary area of Computer Science that entails the development of algorithms and models for extracting, processing, visualizing, and discovering hidden patterns in raw data. Data Extraction and Transformation, Statistical Analysis, Data Manipulation, visualization, Machine Learning, and Predictive Modeling are just a few of the Computer Science disciplines that make use of Data Science methods.

Because data scientists come from a wide variety of experiences and skills, they must be competent in the following areas:

  • Domain Knowledge: A data scientist's primary objective is to extract usable information from raw data that helps a business. As a Data Scientist, you should understand the company's business strategy and ask the appropriate questions to get useful findings.

  • Math Skills: Linear Algebra, Calculus, and other mathematical ideas assist us in comprehending the complicated behaviour of Machine Learning algorithms and identifying hidden patterns. Probability and statistics are mostly utilized in data analysis for predictive modelling and clustering. As a result, you should have a firm grasp of mathematical concepts.

  • Computer Science: Without knowledge of programming languages such as Python, R, SQL, Scala, Julia, or JavaScript, it is impossible to apply Data Science methods. As a Data Scientist, you will work with a variety of databases and noisy networks to analyze data. As a consequence, you should have a basic understanding of programming languages, structures, and algorithms, as well as relational and non-relational databases, distributed computing, and machine learning.

  • Communication Skills: Effective communication with other team members is critical while working on a project. As a Data Scientist, you are responsible for drawing findings from data analysis and communicating them to your team, supervisor, or stakeholders.

Why is Data Science necessary?

At the moment, the industry is in desperate need of competent and accredited Data Scientists. They are among the highest-paid IT specialists. Forbes reports that 'the greatest job in America is that of a Data Scientist, who earns an average yearly income of $110,000'. Only a small handful are capable of processing it and generating useful ideas.


Additionally, in light of the massive and ever-increasing needs, McKinsey predicts that there will be a 50% gap between the supply and demand of Data Scientists in the future years.

Observe this Data Science Insight:

Significant development has been achieved in the area of the Internet of Things (IoT) in recent years, with 90 per cent of data produced in the modern world as a result. Every day, 2.5 quintillion bytes of data are generated, and the rate of production is rising as the Internet of Things grows. This information originates from a number of sources, including the following:

  • Sensors used at shopping centres to collect data on customers

  • Social media posts

  • Photographs and movies taken using our phones

  • Purchases made through e-commerce

Such data are referred to as Big Data.

Businesses are inundated with massive quantities of data. As a result, it is critical to understand what to do with this growing data and how to effectively use it.



This is when the term "Data Science" comes into play. Data Science combines a variety of talents, including statistics, mathematics, and domain expertise in business, and enables a company to:

  • Cost savings

  • Expand your market reach

  • Consider various populations.

  • Determine the efficacy of a marketing effort

  • Introduce a new product or service

And the list goes on and on!

Thus, regardless of the industry vertical in which your company operates, Data Science is likely to play a critical part in its success.

Consider the following infographic to get a better understanding of how Data Science is making its mark.

Google is by far the largest business on the lookout for qualified Data Scientists. Given that Google is increasingly driven by Data Science, Artificial Intelligence, and Machine Learning these days, it pays its workers one of the highest Data Science salaries.

How do industry leaders use data science?

We will examine how major industry giants such as Google, Amazon, and Visa are using Data Science in this part of the 'What is Data Science?' blog. IT companies must handle their complex and growing data environments effectively in order to discover new value sources, capitalize on opportunities, and expand or improve their businesses. The determining element, in this case, is 'how much value a company extracts from its data repository via analytics and how effectively it presents it'. We've formed a list of the largest and most renowned businesses that are currently recruiting Data Scientists at market-leading wages.

Google

Google is by far the largest business on the lookout for qualified Data Scientists. Given that Google is increasingly driven by Data Science, Artificial Intelligence, and Machine Learning these days, it pays its workers one of the highest Data Science salaries.

Amazon

Amazon is a worldwide e-commerce and cloud computing behemoth that is aggressively recruiting Data Scientists. They need Data Scientists to ascertain consumer mindsets and to expand the geographic reach of both the e-commerce and cloud sectors, among other business-related objectives.

Visa

Visa is the online financial gateway for the majority of businesses, processing transactions worth hundreds of thousands of dollars each day. As a result, Visa has a significant demand for Data Scientists to increase revenue, detect fraudulent transactions, and tailor goods and services to meet consumer needs, among other things.

The Data Science Lifecycle

  • Blend & Transform: This step combines, cleans, and prepares pertinent data, which may exist in different systems, according to the criteria of the intended data science method.
  • Model & Visualize: In this stage, analysts make meaning of data using a variety of modelling and visualization approaches, which may involve statistical analysis, data mining, or machine learning techniques.
  • Optimize & Capture: Models and techniques are fine-tuned in order to improve overall performance. Following that, the data science team decides which exact data transformations and calculations should be included in the final production process. When done through Integrated Deployment, this capture process becomes very simple to perform and automate. Notably, this Capture phase entails much more than just delivering a single model or procedure, but rather creating a whole production process, which includes any data transformations needed for the trained process to function correctly in production.
  • Validate & Deploy: At this point, the captured production process has been verified and tested. Validation usually entails quantifying the additional value to the company, validating statistical performance, or confirming compliance. If validation is successful, the production process may be implemented in a variety of ways.
  • Consume & Interact: After deployment, the production process is typically available remotely in one of the following forms: as an interactive data science application, as a data science service that can be integrated into other systems, as a data science component that can be reused by other data scientists, or as a scheduled and automated production process that digests data and returns results in a routine fashion.

After deployment, the production process must be maintained—by monitoring its behaviour, identifying when anything fails or acts unexpectedly, and incorporating improvements and bug fixes.

The New Standard for Bridging the Gap Between Business and Data Science

Apart from describing additional data science technical stages, the Data Science Life Cycle offers a framework for considering sustainable solutions. Rather than seeing "deployment" as the conclusion of any project, we argue that a genuinely effective data science project has no finish.

Once your machine learning model has been decommissioned, for example, the knowledge gained from the data should have influenced how a business user makes choices. And their better-educated input has an effect on the subsequent issue. And the following. Ultimately, data science solutions are built on a foundation of business acumen and data science methods. This benefits business users, data scientists, and the organization's ability to act on facts.

Conclusion

Harvard Business Review did not exaggerate when it said that Data Science is the hottest employment opportunity of the twenty-first century. Today, any digitally-driven company that goes without data for even a little period of time loses its competitive advantage. Data scientists assist businesses in making sense of their consumers, marketplaces, and the whole company.
