Data science is vast field and has various use cases in various industries. Lets take look on Top 6 Data Science Use Cases that are Changing the World. Also you can read A Definitive Guide to Data Science and the Components of Data Science
Predictive modeling
In addition to finding patterns and actionable insights, data science aims to make predictive modeling more accurate. While predictive analytics has been around for decades, data science applies machine learning and other algorithmic approaches to large data sets to improve decision-making by creating models that better predict consumer behavior, financial risk, market trends, and more.
Predictive analytics applications are used in many industries, including financial services, retail, manufacturing, healthcare, travel, and government. For example, manufacturers use predictive maintenance systems to reduce equipment breakdowns and improve product uptime. Aircraft manufacturers Boeing and Airbus also rely on predictive maintenance to improve the availability of their fleets. Similarly, Chevron, BP and other companies in the energy sector use predictive models to improve equipment reliability in environments where maintenance is costly, difficult and expensive to perform.
In addition, organizations are using the predictive power of data science to improve business insights. For example, manufacturers and retailers have developed the static and legacy formulas of consumer behavior. These formulas failed in the face of sudden changes in consumer and business spending driven by the Covid-19 pandemic. However, in forward-thinking companies, these fragile systems are being replaced by data-driven predictive applications that can better respond to customer behavior.
Classification
Data science tools have demonstrated real potential to sort through large amounts of data and categorize or classify it based on engineered features. This is especially useful for unstructured data. Data structured by schema can be easily searched and queried, but unstructured data is more difficult to process and analyze. Emails, documents, images, videos, audio files, text and all forms of binary information are all forms of unstructured data. Until recently, mining data for insights was challenging.
The emergence of machine learning and deep learning, which uses data driven algorithms (including artificial neural networks to analyze large data sets) has enabled organizations to better analyze unstructured data, from image, object and audio recognition tasks to data classification based on document type. For example, data science teams can train deep learning systems to recognize contracts and invoices in piles of documents and identify different types of information.
Government agencies are also working in data science-based grouping or classification applications. Examples include NASA’s use of image recognition to help uncover deeper information about objects in space and the US Bureau of Labor Statistics’ automatic classification of workplace injuries based on analysis of incident reports.
Sentiment and Behavior Analysis
Drawing on the data analysis capabilities of machine learning and deep learning systems, data scientists are digging through reams of data to understand consumer or user sentiment and behavior.
Through applications of sentiment analysis and behavior analysis, data science enables organizations to more effectively identify purchasing and usage patterns and learn what people think about products and services and how satisfied they are with them. These apps can also categorize consumer sentiments and behaviors and track how they change over time.
Travel and hospitality companies have taken this powerful approach to sentiment analysis to identify customers who have had extremely positive or negative experiences so they can respond quickly. Law enforcement operations are also leveraging sentiment and behavior analysis to detect events, situations and trends as they arise and develop, for example by analyzing social media posts.
Amazon – Transforming E-commerce with Data Science
Since its inception, Amazon has been working hard to become a customer-centric platform. Amazon relies heavily on predictive analytics to increase customer satisfaction. It does so through a personalized recommendation system.
This recommendation system is of a hybrid type that also includes collaborative filtering that is comprehensive. Amazon analyzes a user’s purchase history to recommend more products.
It also comes from suggestions pulled from other users using similar products or providing similar ratings.
Amazon has a predictive shipping model that uses big data to predict which products are most likely to be purchased by its users. It analyzes your purchasing patterns and sends products to your nearest warehouse that you can order in the future.
Key features for driving predictive data analytics include Amazon user activity, order history, prices offered by the competition, product availability, etc. It also optimizes the prices on your website taking into account various parameters like this. Using this method, Amazon offers discounts on popular items and profits on less popular items.
Another area that all eCommerce platforms address is fraud detection. Amazon has its own new ways and algorithms to detect fraudulent sellers and fraudulent purchases.
In addition to the online platform, Amazon is optimizing product packaging in warehouses and increasing packaging line efficiency through data collected from workers.
Spotify: revolutionary music streaming
Next up in data science use cases is Spotify. It is an online music streaming company that uses data science to provide personalized music recommendations. With over 100 million users, Spotify handles vast amounts of data.
It uses 600 GB of daily user-generated data to build its algorithms that attempt to improve user experience further. Spotify is a data-driven company that harnesses big data to provide personalized playlists to its users.
Spotify has introduced a lot of analytics features for its artists by introducing the Spotify for Artists app. It allows artists and managers to analyze their streams, fan approval and the hits they generate across Spotify’s many playlists.
In 2017, Spotify used data science to gain insight into which colleges had the highest percentage of party playlists and which colleges spent the most time on them. It posts the findings on its “Spotify Insights” page to report on current trends in music.
Also, in the same year, Spotify bought Niland, an API-based product that uses machine learning to provide better search and recommendations to its users.
Additionally, Spotify analyzed users’ listening habits to predict Grammy Award winners. In 2013, Spotify got 4 out of 6 predictions right.
Recommendation engine and personalization system
User and customer satisfaction is generally higher when products and services are tailored to people’s needs or interests, especially if they can get the right product at the right time on the right channel, with the right offer communicated using the right channel. The right message and the right level. Service and attention. And keeping customers happy and engaged means they’ll keep coming back.
