a) Predictive analytics in marketing

Predictive analytics in marketing is a game-changer for businesses seeking to gain a competitive edge. By harnessing historical data and customer behaviour patterns, Data Scientists can develop sophisticated algorithms that predict future customer actions.

This enables marketers to tailor their campaigns and offers to meet individual customer preferences. It also increases the likelihood of conversions and customer retention. Let’s explore some examples of predictive analytics applications:

Creating targeted ads

Sovrn connects advertisers with outlets like Bustle, ESPN and Encyclopedia Britannica. It uses data from millions of daily deals to power its intelligent advertising technology. It works with Google and Amazon’s server-to-server bidding platforms and can generate revenue from media with minimal human intervention. For advertisers, it will help in targeting campaigns to customers with specific needs.

Curating vacation rentals

Rentals Airbnb used Data Science to enhance its search function. It used to favour top-rated vacation rentals that were close to a city’s centre. That meant users could find nice rentals, but not in trendy neighbourhoods. Engineers fixed that problem by boosting the search rankings of a rental if it’s in an area with a lot of Airbnb bookings. The algorithm also allows for some diversity, so cities don’t overshadow towns, and users can discover the occasional rental treehouse.

Predicting consumers' product interests

Instagram employs Data Science techniques to personalise its sponsored content, ranging from stylish sneakers to influencer-promoted products. The platform's Data Scientists gather data from Instagram and its parent company, Meta, leveraging comprehensive web-tracking capabilities and user information like age and education.

Using this data, they develop algorithms that translate user interactions such as likes, comments, app usage and web browsing history into predictions about the products users are likely to purchase. This approach enables Instagram to deliver targeted and relevant ads to users, enhancing the effectiveness of its advertising efforts.

b) Healthcare diagnostics and treatment

Data Science has transformed the healthcare sector by enabling new ways of diagnosing, treating, and preventing diseases. Let's explore some Data Science Applications related to healthcare diagnostics and treatment:

Identifying cancer tumours

Google has applied Data Science to healthcare by developing a tool called LYNA, which stands for Lymph Node Assistant. LYNA can detect breast cancer tumours that spread to nearby lymph nodes, which are often hard to spot by human eyes. In a trial, LYNA achieved a 99 per cent accuracy rate in identifying metastatic cancer using its machine-learning algorithm. However, more testing is needed before LYNA can be used in hospitals.

Personalising treatment plans

Oncora is a software company that uses Machine Learning to generate personalised treatment plans for cancer patients based on historical data. Oncora's platform is used by healthcare facilities such as UT Health San Antonio and Scripps Health. Oncora's Data Scientists worked with radiologists to analyse 15 years of data from more than 50,000 cancer cases, including diagnoses, treatments, outcomes, and side effects. Based on this data, Oncora's algorithm can recommend optimal chemotherapy and radiation doses for each patient.

ORION has saved UPS millions of miles and fuel per year by using advanced algorithms, Artificial Intelligence (AI) and Machine Learning.

d) Sentiment analysis in social media

Sentiment analysis, powered by Data Science, has become an invaluable tool for businesses to gauge public opinion and perception on social media platforms. Analysing the sentiment expressed in user-generated content helps businesses understand how their brand is perceived and recognise emerging trends and concerns. This content could be anything, such as tweets, posts, and reviews. Let's explore some of the Data Science Applications for sentiment analysis:

Curating matches on dating apps

When singles match on Tinder, they can thank the company’s Data Scientists. A carefully crafted algorithm works behind the scenes, boosting the probability of matches. Once upon a time, this algorithm relied on users’ Elo scores, essentially an attractiveness ranking. Now, it prioritises matches between active users, users near each other and users who seem like each other’s “types” based on their swiping history.

Suggesting friends on Facebook

Meta’s Facebook platform, of course, uses Data Science in various ways, but one of its buzzier data-driven features is the “People You May Know” sidebar, which appears on the social network’s home screen. Often creepily prescient, it’s based on a user’s friend list, the people they’ve been tagged within photos and where they’ve worked and gone to school.

e) Fintech Data Science Applications

Data Science is essential for fintech, as it enables financial companies to use raw data to make better lending decisions and create credit reports. Data Science also helps forecast consumer behaviour, assess risks, and optimise financial portfolios and assets. Here are some examples of how Data Science is applied in fintech:
