Big data is only growing in size, making it more valuable than ever. That’s why faced with a deluge of operational and consumer data. Many corporations are turning to data science to help them navigate through their massive databases and unearth key insights.
Companies surveyed said they currently see 4.4 times the average ROI on their data science initiatives. But that number will grow to 6.7 in the next two to three years. According to Accelerate Your Data-Driven Transformation, a commissioned study conducted by Forrester Consulting on behalf of RapidMiner.
Now, and shortly, data science will be important to company operations. But, first and foremost, what is data science? What is your definition of it? What does it have to do with computer science? And, most importantly, how can you apply it to your company to avoid falling behind? Let’s take a look at each of these questions one by one to help you understand data science. And why it’s so important to every type of organization.
What Is Data Science?
Data science, in its most basic form, is a multidisciplinary approach to extracting value from data using statistical analysis, machine learning, artificial intelligence, and other sophisticated analytics approaches.
However, data science is more than simply a collection of tools. After all, anyone can learn fundamental machine learning techniques, plug in some data, and see what happens. Data science gives critical insight into what these statistics imply, and how data should be acquired and maintained. And how the analysis should be used to answer critical business issues.
Because the goal of data science is to use data to drive insight and create business value, it’s important to note that the work of data science isn’t (or shouldn’t be) limited to data scientists—anyone with domain expertise and business acumen should be able to use data science’s tricks and tools to drive insight for their organization.
How Does Data Science Work?
Anyone can go behind the hood of data science to view the statistics and algorithms that drive the analysis. Much of the data science process is intuitive, starting with determining how data science questions should be phrased, which is why domain expertise is so important.
Five Steps To Data Science Insights
Let’s take a quick look at the five essential processes in every data science project to get a feel of what occurs at each level and how it all comes together to provide business value.
Asking The Right Questions
This may seem self-evident, but achieving effective and insightful data science outcomes requires asking the correct questions. For example, you’ll never receive an effective data solution if your inquiry is too broad or too vague. Data scientists can assist you in better framing your questions so that you receive clear answers and actionable directions.
Another wonderful example is Churn. Many companies would like to be able to forecast when consumers would leave, but merely knowing this information isn’t enough. “How big of a discount should I offer my clients who are about to churn so that they opt to stay, while still maximizing my profits?”
Getting The Right Data
A data scientist may then assist in determining how (and where) to collect the data required for analysis after the proper question has been identified. In some circumstances, this will be information that you already have or are gathering. As digitalization spreads across sectors, this scenario is becoming increasingly typical, and in some verticals that have embraced digital transformations. Such as manufacturing and the Industry 4.0 revolution—highly it’s probable that you already have data to answer several essential business issues.
In other circumstances, you may need to look for new data sources or consider how to incorporate collecting methods into your present workflows to begin establishing a database of vital business data for initiatives like this. It’s crucial to realize, though, that your data will never be flawless. People who opt to wait frequently end up not starting at all, according to our experience.
Cleaning And Wrangling The Data
Because data is never flawless, one of the most critical elements of the data science process is data cleaning and wrangling. It’s the phase in which you modify or remove data points or data categories that are erroneous, incomplete, duplicated, corrupted, or poorly structured. Or otherwise misleading from datasets before analyzing them.
Data cleaning is an important step in data science since failing to eliminate items like strong outliers and irrelevant categories can result in results that are utterly incorrect or uninterpretable. The cleaning procedure might take far longer than the research itself. One statistic claiming that data scientists spend up to 80% of their time wrangling and cleaning data. As a result, if you want strong outcomes, you’ll need a solid data preparation strategy in place.
Analyzing The Data
This is the heart of data science, and it’s where you can use all of the tools and knowledge you’ve learned so far to unearth useful information. The process of data analysis and model construction is iterative, and numerous parameters may need to be tweaked as you go.
Another reason for the importance of adequately phrasing the issue you’re attempting to answer is that it allows you to focus your efforts. Returning to the churn scenario, you could believe that your work is done once you’ve discovered the characteristics that cause a client to churn. If you’re asking yourself, “What action should I take to maximize my profits?” you’ll realize that identifying customers who are likely to churn is only the beginning of your analysis; you’ll also need to figure out how to keep as many of them as possible while providing the lowest discount possible.
Communicating The Results
The finest data in the world is useless if it isn’t understandable. That’s why data scientists must be able to do more than crunch statistics. Data visualization is a fantastic approach to make this easier. Understanding what important ideas you’re attempting to express ensure that viewers intuitively understand those insights. And then offering adequate context to account for crucial correlations and patterns is the key to showing data.
It will be simpler for other data scientists and key decision-makers to evaluate, make conclusions, and implement suggested actions.
Data Science Versus Computer Science
Although data science and computer science are closely related, they are distinct in fundamental respects. Data science is all about researching, storing, managing, and analyzing massive amounts of data. Whereas computer science is all about the tools for isolating and manipulating digital data. Data science is what companies (should) operate on, while computer science is what computers work on.
How Can Data Science Be Applied?
Let’s look at a few concrete use examples that demonstrate the real range of data science processes in various businesses and domains.
Online Ads
Data science assists ad suppliers such as Facebook in presenting ads to customers who interested in the ad’s content. That’s because data science aids in the organization of data and the ongoing evaluation of indicators such as demographic reach, performance against cost, and conversion rate versus media type. These approaches can help you improve your advertising and make sure the correct people receive your message at the right moment.
Recommendation Algorithms
Netflix knows you’ll like binge-watching Ozark soon after you complete Mindhunter, and Amazon keeps recommending baby toys after you’ve looked at a few onesies, according to data analytics. Algorithms assist businesses in predicting what their customers would appreciate based on previously collected data. Any company may profit from this sort of information. Since it allows you to adjust how your website communicates with visitors and customize consumer interaction preferences and purchase history.
Image Recognition
With AI and deep learning, image recognition has evolved dramatically in recent years. And we can now use it to consistently recognize individuals, places, brands, patterns, colors, and forms. The possibilities for this are practically limitless, ranging from increased automation to quality control, targeted advertising, and security.
Speech Recognition
Speech recognition technology like Alexa, Siri, and Cortana, which allow users to communicate with their gadgets, houses, and automobiles, uses science of data science. Even more basic versions of these applications are now available via simple APIs, allowing anybody to communicate with computers or digital devices. And receive replies to spoken inquiries and commands.
Price Determination
Finding the greatest deal on a product is no longer as straightforward as it once was. Factors such as your IP address, how many times you’ve visited a price, and broader influences such as demand and weather all play a role today. Using complicated algorithms to figure out when your company should acquire key products. And how much you should charge for them—can result in significant savings and profits.
Fraud Detection
Modern fraud detection relies heavily on machine learning. There’s never enough time for a person to analyze each case individually to see if there’s a chance of fraud. That’s why using algorithms to spot purchase trends and abnormalities, stop possible fraud in its tracks. And take appropriate action—including elevating cases to people when necessary—can save a company a lot of money.
Delivery Logistics
For any human, figuring out how variables like weather, traffic, driver availability, regular vehicle maintenance, and regulatory requirements interact is a difficult process. Modern firms may use data science approaches to take all of these elements into consideration. At the same time and get reliable projections that they can trust.
What’s The Future Of Data Science?
The fact that governments, educational institutions, commercial corporations, and even interested people are investing in data science and machine learning. At the same time shows that the subject has finally evolved past the boom-and-bust cycles that characterized its early years. The current investment is motivated by the knowledge that data science consistently delivers ROI across sectors through established and reproducible use cases.
Most firms that are just getting started with these technologies need to be able to look through the hype and complexity to the real value that data science can deliver.
