1. Recommendation Engines
Recommendation engines are the most important tools in a retailer’s arsenal. Retailers leverage these engines to drive a customer towards buying the product. Providing recommendations helps retailers increase sales and to dictate trends.
Sounds familiar? Thinking of Amazon and Netflix? That’s exactly how search recommendations work.
How do they do this?
Well, that’s simple, the engines are made up of complex machine learning components and deep learning algorithms. They are designed in such a way that they can keep a track record of every customer’s online behavior and analyze the patterns to suggest shows based on this data.
That’s why every time Netflix recommends movies or TV series to you, it’s probably something you are going to watch! The same thing works with Amazon too, based on your past searches and purchase history, amazon provides recommendations and discounts on them as well. Because let’s face it, who can resist buying something that they always wanted, especially when it comes with a discount? This whole process involves a great deal of data filtering and analysis by machine learning algorithms.
2. Market Basket Analysis
This is one of the most traditional data analytics tools that retailers have profited from for years. Market basket analysis works on the concept- if a customer buys one group of items, they are more or less likely to buy another set of related items. For example, if you went to a restaurant and ordered starters or appetizers without any drinks, then you are more likely to order the main course or desserts. The set of items the customer purchases is known as an itemset, and the conditional probability that a customer will order the main course after starters are known as confidence.
In retail, customers purchase items based on impulse, and market basket analysis works on this principle by predicting the chances of a customer’s purchasing behavior.
This mostly involves a lot of how the retailers do the marketing of the product, and in the world of e-commerce, customer data is the best place to look for potential buying impulses. Similar to search recommendations, market basket analysis also works with a machine learning or deep learning algorithm.

3. Warranty Analytics
Warranty data analytics helps retailers and manufacturers keep a check on their products, their lifetime, problems, returns and even to keep a check on any fraudulent activity. Warranty data analysis depends upon the estimation of failure distribution based on data that includes the age and number of returns and the age and number of surviving units in the field.
Retailers and manufacturers keep a check on how many units have been sold and among them how many have been returned due to issues. They also concentrate on detecting anomalies in warranty claims. This is an excellent way for retailers to turn warranty challenges into actionable insights.
4. Price Optimization
Selling a product at the right price, not just for the customer but also for the retailer or manufacturer is an important task. The price must not only include the costs to make the product but also the ability of a customer to pay for that product keeping in mind competitor prices as well.
All of this is calculated with the help of machine learning algorithms which analyze a series of parameters like the flexibility of prices, taking into consideration the location, buying attitudes of an individual customer, and competitor pricing. It then comes up with the optimal price that can benefit all the parties. This is a powerful tool for retailers to market their products in the right way with optimal pricing.

5. Inventory Management
Inventory refers to the stocking of goods, for later use in times of crisis. Hence, inventory management is crucial for businesses to optimize resources and increase sales. Retailers need to manage inventories effectively so that even if there’s a sudden spike in sales, supply remains unaffected. In order to achieve that, the stock and supply chains are thoroughly analyzed.
Powerful machine learning algorithms analyze data between the elements and supply in great detail and detect patterns and correlations among purchases. The analyst then analyzes this data and comes up with a strategy to increase sales, confirm timely delivery and manage the inventory stock.
6. Location of New Stores
Location analysis is an important part of data analytics. Before a business can decide where to open up its business, it is crucial to analyze plausible business locations to settle on the best one.
The algorithm used in this case is simple, yet effective. The analyst analyzes the data giving importance to demographics. The coincidences in zip codes and locations give a basis for understanding the potential of the market. Competitor markets are also taken into consideration while analyzing locations. The algorithm also analyses retailer networks to come up with the most suitable option.
7. Customer Sentiment Analysis
Customer sentiment analysis has been around in the business world for a long time. But now, machine learning algorithms help simplify, automate and save a lot of time by giving accurate results.
Social media is the most readily and easily available tool for an analyst to perform customer sentiment analysis. He uses language processing to identify words bearing a negative or positive attitude of the customer towards the brand. This feedback helps businesses improve their product.

1. Risk Assessment and Management
There is a risk factor in every business which is crucial to assess so that it can be managed in time. In the finance sector, the risk assessment and management process involve measures from identification of risk to mitigating the uncertainty. Risks could be related to financial crises, payment defaulters, or any other operations in the ecosystem. Companies need to assess and manage risks to save resources, protect their brand or reduce their legal liability.
A lot of financial data is generated relating to credit card transactions, credit history, price fluctuations, trade data, and so on. Data science is used to study these data sets to understand the areas of concern and take the necessary steps to mitigate these risks. Data science allows the analysis of big data sets to give sufficient insights to risk managers.
The application of data science in finance helps risk managers in various domains including counterparty credit risk and anti-money laundering (AML). Defaults in transactions are not uncommon. Counterparties to a transaction may default before the final settlement. This is known as counterparty credit risk and data science is used to assess the risk before a transaction is initiated. Similarly, data science has found applications in AML. Money laundering is often associated with illegal activities and a cause of social problems. AML is implemented to comply with regulatory bodies and protect brand image, apart from moral obligations to society.
2. Fraud Detection and Prevention
Fraud in the financial industry relates to tax evasion, insurance claims, or identity theft. Tracking fraud possibilities and taking steps to minimize loss is a matter of priority for businesses. Continuous improvement in the application of data science in finance has resulted in more efficient systems that can detect the possibility of fraud much before its occurrence.
When big data is analyzed using data science, fraud detection is much more accurate and gives companies the ability to act against such crimes in real-time. For instance, unusual variance in credit card usage or banking transactions may flag them so that appropriate action may be taken. This helps the organization protect a customer as well as the company’s reputation and operation.
Fraud in insurance claims also can be detected with the help of data science. Data of past claims are explored and analyzed to understand patterns. This is used to spot possibilities of false claims.
Data science has improved the efficiency of fraud detection systems in financial organisations by reducing false positives, increasing the detection of actual fraud, and developing resources to manage that.

Data science tools enable predictive consumer analytics helping in increasing response rates, repeat customers, and profitability. Insights from these analyses also help improve their promotion campaigns’ performance. Campaigns curated with such insights are delivered to those consumers who are most likely to respond positively to offers. Campaign costs are also reduced with lesser and more focused recipients.
Insights also present an opportunity to prevent consumers from switching to a competitor. Their future actions can be predicted and responded to with suitable offers using these insights. They can also help gauge the lifetime values of customers.
5. Customer Data Management
In the current competitive business environment, customer data management is critical for the profitability of a business. Using data science, companies can understand almost anything about a consumer that is relevant to the business with big data analysis.
Organisations can now access consumer purchase behavior and demographics. This data can be analyzed to understand market trends and gauge consumer behavior. Customer data management gives a holistic view of consumer behavior and helps in making data-driven decisions.
Proper implementation of customer data management can considerably improve customer retention and satisfaction leading to higher profitability. Financial institutions benefit the most by analyzing the current customer data and data of customers at the bottom of the funnel. Customers with higher lifetime value (CLV) may be managed separately for better monetary growth.
6. Delivering Customized Services
Delivering customized services while keeping customers’ needs in mind is an effective customer acquisition and retention strategy. Customer satisfaction and loyalty levels differentiate companies from their competitors. Personalized services are not new, but their implementation has been continuously evolving.
Companies use historical customer data and feedback in the finance industry to deliver more suitable financial services. Banks and other financial institutions integrate operational data with customer data across all channels and divisions of the company to enhance the customer experience at all touchpoints.
Data science tools are used to analyze historical data and create a 360-degree view of a customer. The comprehensive data and insights derived from them are at the core of all personalization services. There has been a gradual shift in the customer journey in the banking and financial services industry. With a decrease in face-to-face interactions, multi-touch attribution models fill the gap and help in understanding consumers better.
