Introduction

Hey, Ninjas! You must have heard of the term 'Data Science'. It is because of its diverse applications, which range from early detection of diseases in the human body to recommending new web series on Netflix. It can analyse student data, it can also help in predicting congestion on city roads. With enough data in hand, we can use data science to create predictive models to predict future conditions.

But what exactly is data science, and where can we see it? Well, don't worry! In this article, we're going to explore what data science is all about and where it's used. So, Let's start our journey.

What is Data Science?

Till the 60s, data science was just used as an alternative name for statistics, but now it involves three aspects: data designcollection and analysis. Moreover, it is used to extract meaningful insights from business data. To give you an overview, the business data includes statistical information, raw analytical data, customer feedback data, sales numbers and other sets of information.

  • Data science uses principles and practices from mathematics, statistics, AI and computer science.
  • Data science applications range from discovering unknown transformative patterns to innovating new products and solutions based on data.

Let us have a look at the Data Science Process

Data Science Process

It is a systematic approach towards a data science problem. It provides us with a structured way to formulate, solve our problem and finally present the solution to the stakeholders.

Typical data science process involves:

  • Data Collection: Data is collected from various sources as per the problem requirement.
     
  • Data Cleaning: Collected data then gets cleaned. 
    For example, If collected data has a record that contains some missing attribute then the such record will be removed.
     
  • Data Exploration: It provides an initial statistical understanding of the data.
     
  • Data Modelling: The model is chosen by minimising the error.
     
  • Interpret Result: The result from the model can be obtained and used for multiple purposes.

Following are some of the applications where generated model can be applied: 

  • Early disease detection using predictive modelling 
    It is possible to provide early intervention for diseases like diabetes or cancer by developing a data science model. The model will analyse the patient data. After analysis, It will predict the likelihood of developing such a disease.
     
  • Medical Image Analysis for Diagnosis
    We can use deep learning techniques to analyse medical images, such as X-rays, MRIs and CT scans, to diagnose various conditions.

 

Finance Industry

Company Reports and Regulatory Filings to the government along with financial databases from organisations like  Bloomberg, Capital IQ, and Thomson Reuters are used to prepare data science models in the finance industry.

data-science-in-finance

Following are some of the applications where generated model can be used: 

  • Using anomaly detection techniques to detect fraud
    We can develop machine learning models to analyse financial transactions and identify suspicious activity. It can flag potential fraudulent transactional activities.
     
  • Using credit risk analysis for loan approvals
    We can analyse customer expenditure behaviour and customer credit history to assess credit risk. This analysis will determine whether to approve or deny a loan application.
     
  • Optimising portfolio for better investment
    We can develop a model for analysing market trends and past performance of different stocks to optimise our portfolio, which can give us maximum return while minimising risk.

Retail Industry

The transaction history of the customer, description of the products, customer reviews, geographical location, etc. are key components to consider while preparing data science models.

data-science-in-retail

Following are some of the applications where generated model can be used: 

  • Personalised marketing based on customer segmentation
    Data science can be used to analyse customer data. We can segment customers into different groups based on their behaviour. We can craft personalised marketing campaigns for each group.
     
  • Forecasting of demand and inventory management
    Sales data can be analysed using data science models. It will help us forecast demand for different products. Based on the forecast, we can optimise our inventory levels. Stockouts can be avoided and hence will minimise waste.
     
  • Product recommendation system
    A data science model can analyse customer purchasing behaviour and preferences. This analysis will help us in curating personalised product recommendations for customers.

Frequently Asked Questions

Why should we use data science?

Data science can be used to do predictive modelling. We can extrapolate historical data to predict future conditions. It can segment our dataset into different groups and finally use a different strategy for each group.

What are the most common techniques used in data science?

Data cleaning, exploratory data analysis, data visualisation, statistical modelling, and predictive analytics are the most common techniques used in data science. They are required to identify patterns in data and make predictions for various applications.

What are some of the ethical considerations related to the use of data science?

We must obtain consent for data use. It is our responsibility to use data for social good and ensure responsible AI. Complying with relevant laws and regulations of geographical units is also necessary. 

What is the future prospect of data science?

More and more businesses are looking to incorporate data science into their respective field of applications. We seek new and exciting healthcare, finance and entertainment innovations. New emerging AI and Machine learning technologies are also improving data science's future scope. 

Conclusion

To conclude, data science applications are present in every field. Data science is continuously leveraged in fields such as healthcare, education, finance etc. Data science models can predict future trends after analysing historical data. Data science is also helpful in providing more personalised attention to customers. In short, in the coming days, data science is going to touch every aspect of human life and we all are going to reap the fruits of data science.
