Five Machine Learning Use Cases in Insurance with High Business Value
There are many potential machine learning use cases in insurance. The specific use cases that are most important will depend on the specific needs and goals of the insurance company. However, some common use cases in insurance include the following:
- Underwriting: Machine learning can improve underwriting by automating the process and reducing the risk of human error.
- Fraud Detection: Machine learning can help detect fraudulent claims by identifying patterns and anomalies in data.
- Customer Segmentation: Machine learning can help insurers segment their customer base and develop targeted marketing strategies.
- Claim Processing: Machine learning can automate and accelerate the claims process, making it more efficient and accurate.
- Risk Modelling: Machine learning can help insurers model and predict risks more accurately, allowing them to make better-informed decisions.
Underwriting plays a crucial role in the insurance industry, involving the assessment of risk and determination of suitable premiums for coverage. The objective is to ensure profitability by accurately evaluating and pricing risk. Underwriters evaluate applicant information, such as age, health, and financial history, to predict the likelihood and cost of potential claims. This information, alongside other factors, guides the calculation of policy premiums.
Machine learning enables insurers to automate and enhance the underwriting process, making it more precise and efficient. By training models on historical data, patterns and trends associated with varying levels of risk can be identified. For instance, algorithms can recognize that individuals with specific medical conditions or occupations are more likely to make claims on their policies.
With advancements in Natural Language Processing (NLP), algorithms become proficient in understanding textual information. They can discern policy terms that correlate with higher or lower levels of risk. Once trained, these algorithms can evaluate new applicants and predict their risk levels, aiding insurers in making informed decisions regarding acceptance, rejection, and appropriate premium rates.
Machine learning empowers insurers to streamline underwriting procedures, ensuring accuracy, consistency, and improved risk assessment for sustainable business practices.
2. Fraud Detection
Insurance fraud is a serious problem that costs the insurance industry billions of dollars annually. It refers to the act of intentionally providing false or misleading information to an insurer, and it can take many forms. For example, customers may provide false information on a policy application, exaggerate the value or extent of a claim, or stage an accident or theft to make a claim. Service providers such as hospitals may also engage in fraud by exaggerating the costs of treating a patient.
Fraud is a significant issue for insurers, as it can lead to higher insurance premiums for all policyholders. It is estimated that insurance fraud costs the industry approximately $80 billion each year. To combat fraud, insurers are turning to machine learning to analyze large datasets of claims data and identify patterns and anomalies that may indicate fraudulent activity.
Machine learning algorithms can analyze vast amounts of data to identify suspicious behavior that may be indicative of fraud. For example, machine learning can be used to detect patterns of behavior that are inconsistent with normal claim activity, such as a sudden increase in claims activity from a particular location or a sudden change in the type of claims being submitted. By identifying these patterns, insurers can more effectively detect and prevent fraudulent activity.
Another way in which machine learning is helping insurers combat fraud is by identifying relationships between claimants. For example, machine learning algorithms can analyze social media data to identify connections between individuals who have submitted claims. This can help insurers detect cases of fraud in which multiple individuals collude to submit false claims.

3. Customer Segmentation
Customer segmentation is the process of dividing a customer base into smaller groups with similar characteristics. This is often done so that a business can tailor its products or services to the specific needs of each group, and can also help a business to target its marketing efforts more effectively. For example, a clothing retailer might segment its customers by age, gender, income level, and location, and then offer different promotions or discounts to each segment in order to maximize sales. However, collecting and using personal data to segment customers can raise concerns about privacy and data protection. Insurers must ensure that they are collecting and using customer data in a responsible and ethical manner and that they are complying with all relevant regulations and laws.

Machine learning can help cope with the challenges of customer segmentation in several ways. It can help identify more relevant and accurate segments by analyzing large amounts of data and identifying patterns and correlations that may not be obvious to human analysts. This can lead to more precise segmentation and a better understanding of customer behavior. Secondly, machine learning algorithms can be used to automate the process of segmenting customers. By inputting data such as demographic information, purchasing history, and online behavior into a machine learning algorithm, insurers can quickly and accurately identify the most relevant segments for their business. This approach can also help insurers better personalize their interactions with customers within each segment.

4. Claim Processing
Claim processing is the process of evaluating, investigating, and resolving insurance claims. It typically involves verifying that the claim is valid and covered under the terms of the policy, determining the amount of the payout, and issuing payment to the insured party. Claim processing can be done manually or with the aid of specialized software. The goal of claim processing is to ensure that valid claims are paid quickly and accurately and that any fraudulent claims are detected and denied. Machine learning can help insurers identify patterns and trends in claims data, which can be used to detect potential fraud or other anomalies. It can also be used to automatically process claims, reducing the need for manual intervention and speeding up the process.
In addition, machine learning can help insurers make more accurate decisions about the payout amount for a claim. By analyzing data such as the type of claim, the severity of the damage, and the policyholder’s history, machine learning algorithms can predict the expected payout and ensure that it is fair and accurate. However, there are potential challenges in using machine learning for claim processing. One challenge is ensuring that the algorithms are fair and unbiased, as biased algorithms can result in discrimination against certain groups or individuals. To address this, insurers must take proactive measures to ensure that their machine learning algorithms are fair and unbiased.
5. Risk Modeling
Insurers can use machine learning to develop more accurate and sophisticated models of their risks. For example, models can assess the risk associated with insuring a particular individual or property. Insurers can use such models to make more informed decisions about the risks they are willing to take. One specific use case is crime prediction, which we have recently covered in a separate article. Insurers can determine the likelihood that a person or property will be a victim of a specific crime. Following this understanding, they can then adjust their offerings accordingly.
Risk modeling can also use satellite data. This data can include information on weather patterns, topography, land use, and other factors that can affect the risk of natural disasters, such as floods and hurricanes.
Insurers can use satellite data to create detailed maps of areas at risk of natural disasters. These maps can include information on the type of terrain, the density of vegetation, and the location of buildings and infrastructure. This information can be used to create models that predict the likelihood of damage from natural disasters in a particular area.
Insurers can also use the data to create more accurate and detailed flood and wind hazard maps. These maps can help insurers to determine the risk of insuring a particular property and can also help them to create more accurate pricing for policies. In addition, by using satellite data to monitor the changes of a given area, insurers can also detect if there is any new constructions or any new developments in the area that can affect the risk level of a certain property.
