Anomaly detection is a method to notice anomalous actions or data. It predominantly focuses on the problem referring to recognize all intrusive attacks based on their anomalous activities that diverge from “normal activity profile” in a system. It also checks to see if an activity is within the predetermined acceptable condition. If it is not in this scope, it assumes that it is known as an unacceptable or bad attitude. The common way of the anomaly detection method occurs from the following components: First, a basis for all acceptable behaviors and situations is created. All activities observed while establishing this basis are taken as basis. The current situation is configured. This configuration is for a model that can be interpreted by applicable technologies. The observed activity is compared with the basis model that created, it is checked whether there is a deviation. Situations that observed as an anomaly are reported. Anomaly detection, rare observations or situations that are disparate from the remainder of the watchings, which may cause suspicion. Such "abnormal" situations typically transform into a kind of problem, such as a fault machine on a server, cyber attack, failure capsules in the cloud network, financial frauds, mobile sensor data, statistical process control (SPC) for production.
The best anomaly detection frame:
1-) Estimate main errors with up to 95% accuracy,
2-) Notice uncommon changes in system actions spontaneously,
3-) Service providers should strictly know how to fix issues. Therefore, show elementary to understand root cause analysis.

Challenges in Anomaly Detection Models

Some difficulties make the task of anomaly detection difficult. Machine learning algorithms often need large amounts of data. This is because anomalies are not very likely, they are statistically small, and data sets are often unstable. Train and test data of models that developed for detect anomalies may be finite. It may also be unlabeled for testing and training. For example, there are states that normal behavior is more than abnormal behavior. This causes additional difficulties in training models that detect and predict abnormalities. Anomaly detection system ought to be as a dynamic system with fast-growing usage bases. In addition, as the underlying system develops, it has to update its behavior over time and adapt it to development.

How Anomaly Detection Approach Works?

Technically, the most distinctive criteria between normal and abnormal data point is whether there are similar data points around it in the analytical plane. In this context, the areas where similar points become very clustered are considered normal, and the areas where they become sparse are called abnormal areas. This is where the inference benefits of machine learning algorithms on analytical planes come into play. After these regions are determined by machine learning algorithms, abnormalities of data points are predicted. Unbalanced data visualization that taken from Towards DataScience



Many machine learning algorithms have been developed throughout the history of machine learning to identify these areas. So what makes machine learning algorithms different for abnormal detection processes? There are 2 major detection ways to process abnormal patterns; supervised and unsupervised anomaly detection.

Supervised Anomaly Detection:

The tagged dataset that includes both abnormal and normal sample data to create a prediction model that can classify future data points is needed for the supervised anomaly detection method. Algorithms such as Support Vector Machine Learning, Supervised Neural Networks, K-Nearest Neighbors Classifier are frequently used algorithms for this motive.

Unsupervised Anomaly Detection:

In this method, any training data does not necessary. Unsupervised anomaly detection assumes two things about data rather than training data. Only a percentage of the data is abnormal and any anomaly is completely dissimilar from normal samples. After these surmises, the data is clustered using the measure of similarity, and then data points that away from the cluster are appraised as anomalies. Large labeled data sets are needed to train these algorithms and achieve high-performance estimation results. Conversely, it is difficult to obtain such large-scale tagged data sets, and field knowledge from professional is necessary for the disclosure process.

The thriving performance of supervised learning in previous years has also led to unsupervised learning achieving very good results. Although there is a new tendency to adopt unsupervised attempts, attempts based on ML algorithms on anomaly detection generally focus on supervised models. The scarcity of tagged data is increasingly seeking to develop unsupervised learning models. B2Metric Machine Learning Studio (Register & Start Free Trial Now!) can be applied to these and many other problems, it solves these problems for you and allows you to make anomaly determinations in the most accurate way.

Real World Scenario of Where Anomaly Detection Used?

Anomaly detection affects business decisions across sectors. Sectors such of, insurance, finance, telecom, manufacturing, banking are the main sectors which anomaly detection is of great importance. Detection and prevention of abnormally high purchases-deposits, fraudulent spends, revenue fraud, abuse, service disruptions are main real case scenarios of anomaly detection.

Insurance Frauds

According to FBI reports; there is $40B loss for Insurance frauds in United States every year.

Anomaly detection in the insurance sector is one of the services that takes basic problems in different fields of insurance. For instance, identification of fraud in insurance and securities, and irregularity detection in health services' data are among the scopes of anomaly detection in insurance. In addition to these services, increasing cybersecurity calls have become a need in the insurance industry in recent years. With these developments, damage fraud detection actions have started in the insurance industry. In short, anomaly detection is a method used for insurance fraud detection. For instance, insurance companies can use anomaly detection technology to identify suspicious user behavior in the insurers' network.

Anomaly Detection for Telecommunication Industry

With the development of the telecommunications sector, the sector started to produce and collect huge amounts of data. These data are so large that it is impossible to deal with this data manually. Therefore, data mining technologies for the telecommunication sector develop. Abnormal situations such as network failures occurring in telecoms and unusual customer calls are called anomalies. Detection of these anomalies has an important place in the telecom sector.

Cyber Security Anomaly Detection

Network monitoring tools owned by cyber security systems can learn normal network behavior due to the large amount of data they have. Entries that unusual and intrusion are called anomalies. These anomalies must be detected and intervened to ensure cyber security. Denial of service (DoS) attacks is an example of anomaly. Although they don't crash or receive data, DoS attackers aim and focus on downloading a network and rejecting service to legitimate users. Starting DoS attacks is easy. DoS attacks block users from getting the right service by forcing physical resources or network connections. The attack happens the service is filled with too much traffic or data. Therefore, DoS attacks must be detected. For this, first of all, normal behaviors should be specified in the system. Then the system should alarm when the behavior deviates from normal to anomaly (DoS).

Network Faults Anomaly Detection

In order to provide high quality service in IP networks, the downtime of the service should be shortened as much as possible after the network errors occur. However, there are also network errors that cannot be detected by operators by simply monitoring device states. It is necessary to focus on anomaly detection to solve such abnormal problems.

Customer Journey Analysis is an approach to help a company see its products and services from a customer's perspective. Before the analysis, what the customer journey is and its importance should be examined. Do you know what is it and why you need it?

What is Customer Journey?

Customer journey cites to the path followed through the points of contact of your customers and potential customers before making a purchase action. Customer Journeys explains the path to successive interactions a customer has with a product, service, and company. A customer journey is an observation way about understanding your users, how they behave while they visit your website, and what you can do to improve their trip. They keep coming because of this observation.

Marketing is the main area of ​​use for customer analysis. There have been major changes in customer behavior in recent years. Customers usually do not decide to buy a product at the first interaction now years. They often examine different brands several times for a product or service before making a decision. Continuously developing mobile technologies enabled customers to interact with organizations from many different channels. On the Internet, the points of contact of potential customers for a product or service are hard can be watched from multiple channels.

How Can You Analyse a Customer Journey Map?

Journey maps are infographic visualizations to understand how a customer is working towards a goal over time. There are several ways for analyze customer journey maps.

1) Identify points where customer expectations are not met. When users interact, if this interaction does not meet expectations, pain points are seen on the journey. In these cases, it is necessary to think from a user perspective. So you can understand which interactions did not meet the old expectations and experiences.

2) Identify any unnecessary touchpoints. Whether to take steps that can be eliminated to facilitate the overall experience should be examined. You should look for ways to reduce the cost of interaction.

3) Look for low points. You should see where the lowest points of the journey come from. Determine which low points you should prioritize.

4) Bestow time periods for the main stages of the journey on your travel map. Consider how long it took users to reach the sub-steps and whether these elapsed times were appropriate.

5) Look for moments of truth. Some points are based on some other points on the journey. These points are very important for the journey. If these moments go well, they can save the journey. You should analyze these points well and make sure you pay attention to them.

6) Identify the points that expectations meet. Look where the customer journeys are highest. These points are usually interactions that users are happy with. You can use similar experiences in different places. Thus, experiences will increased by you.

7) Determine high-friction channel transitions. There are many trips between the channels. The journey is disturbed when users change channels and transition should be facilitated.

The World Health Organization (WHO) was informed of an outbreak of “pneumonia of unknown cause” detected in Wuhan City, Hubei Province, China – the seventh-largest city in China with 11 million residents on December 31, 2019. As of January 23, there are over 800 cases of 2019-nCoV confirmed globally, including cases in at least 20 regions in China and nine countries/territories. Later on, Chinese authorities reported that laboratory tests excluded SARS-CoV, MERS-CoV, influenza, avian influenza, adenovirus, and other common respiratory pathogens. Coronaviruses are known to be a large family of viruses, some of which cause less serious diseases like the common cold and others more serious diseases like MERS and SARS. However, some of them are easily transmitted from person to person, while others do not transmit.

Corona Virus in Our Lives

Covid-19, commonly known as coronavirus, is a serious global infectious disease outbreak with more than 400,000 cases and over 25,000 deaths worldwide up to 28 March. You can check the numbers whenever you want from the Covid-visualizer. The coronavirus has a huge impact on almost every aspect of our daily life. Everything from our social habits to our working order has recently changed with this virus. These changes not only happened in our personal life but also affected all sectors. The insurance sector is also one of the sectors affected by the virus.

Coronavirus Effects on Insurers

The Coronavirus Disease (COVID-19) outbreak will likely influence life insurers in the following ways: Increment incurred claim costs, including death and disability claims, and drug prices. Adverse actions in the financial markets, covering declines in bond yields, equity markets, and real estate, decreasing profitability. Business deduction and potential influence on profitability. As coronavirus continues to extend across to the whole world, its effects are rippling across financial markets and the global economy. The life insurance industry is no exclusion, particularly given the incrementally global nature of many insurers and their biggish investment portfolios. Although most countries have had minimal reported coronavirus cases so far, and as a result, the efficacy on claim costs for life insurers is remissible to now, the effect on business operations for some global insurers has already emerged, particularly for those operating in high-risk regions such as US, China, Iran, and Italy. Most life insurers await to feel the effect of coronavirus on the financial markets because of the highly interlinked global economy. Officials said the coronavirus has changed customers' behavior, and insurance companies should take this into account. According to Christopher Woolard who is the interim chief executive of the FCA,(Financial Conduct Authority) insurance firms should realize this and treat their customers fairly, realizing the conditions customers may find themselves in. Epidemics are eliminated from many business insurance policies, therefore the early prognosis was for low levels of claims. But as stagnation intimidations, the global economy along with incrementing insolvencies, all sorts of companies with trade credit insurance are coming under strain. Meanwhile, insurers’ investments are also coming under strain.

How Pandemic Effects on Car Insurance

Obviously the coronavirus will deeply affect the health insurance and also car insurance industry especially car purchases and loans affected by this pandemic. The ability to pay car insurance will also be affected by the coronavirus. Therefore some insurance companies are extending the time for their customers who have difficulty paying due to the coronavirus pandemic. According to WHO, almost 1.24 million people die in car crashes worldwide and according to Safer America, the yearly cost of traffic accidents in the United States is estimated to be $871 billion. These rates and numbers are expected to drop due to the virus, even if precise data has not yet been shared. Because, with the virus, driving rates decreased. This caused the accident rates to drop.

Above are the weekly death rates in the USA. Here, we see that death rates have decreased because of the reduction of leaving home due to corona. This decrease is expected to be seen in the rate of traffic accidents for the same reason.

Do the Turkish Life Insurers have COVID-19 covered?

There is a great article that posted by KPMG here  Do insurers have COVID-19 covered? 
In Turkish market as well as worldwide through, many insurance companies have taken the necessary measures against the coronavirus and have taken essential steps. Mapfre Sigorta, Bupa Acıbadem Sigorta, Groupama Sigorta, Eureko Sigorta, and Allianz are the insurance companies that announce a good news for Covid-19 patients. Their life insurance cover all of their corona treatment costs without exclusion.

The use of AI and machine learning is becoming more and more common. With the widespread use of artificial intelligence and machine learning, AI started to be used in every field of business. Telecommunication is the main one of these fields. Because the telecommunication sector is one of the fastest-growing industries and the one that is affected by innovations quickly. The largest telecommunication companies worldwide also closely follow artificial intelligence and ML and develop various artificial intelligence applications. Some common examples of these application uses are:

Customer Propensity Prediction

Customer data is very important in the telecommunications sector. With the use of artificial intelligence, meaningful information is extracted from these data. AI applications evolve for the best customer communication in telecoms and analyze their movements for them. B2Metric AI exists to predict and procure customers' next step and provide the best option for them.

Marketing

Telecommunication companies can use data for creating better profiles for customers and allocate a marketing budget. With developed data structure, they are able to collect and store much more data that provide insights into each customer such as demographics, location, devices used, the frequency of purchases, and usage patterns. They also can have a stronger understanding of their customers by using other sources like social media and combining data from coming there.

Fraud Detection

Machine learning algorithms are efficient in detecting fraudulent behavior such as fake profiles, illegal access, theft, and more with anomaly detection of data. The power of technology-driven fraud detection solutions is derived from their ability to process large sets of data. The general rule is the more data is better, which consequently improves the accuracy and effectiveness of the analysis. B2Metric AI uses several data sources, both internal and external, to help identify fraudulent behavior in realtime with its anomaly detection modules.

Customer Churn Prevention

Customer churn means that the loss of an extending customer to an opponent. Churn prediction is highly important for each industries and also for telecoms because winning new customers is a highly costly issue. Retaining existing customers are cheaper than obtaining new customers. Also, older customers, who have no voluntary deductible excess, are generally non-churning customers. Newer ones, do churn more often. Therefore, telecommunication companies notice that to hold on to existing customers is getting more important. They also agree that churn analysis is one of the main data mining application areas. Hence, decreasing customer churn is the main business target of the telecom business. To manage customer churn, churning customers should be identified first. Then these customers must be convinced to stay. B2Metric AI prevents your customer churn rate by %20 to %50 with robust Churn prediction models that make efficient service.

Network Planning Systems

The creation of network planning systems will require evolving integral technologies like question answering, language transition, speech synthesis are some of the evolving techniques of telecommunication fields. Other applications like digital companding, AI-based network planning systems, are some of the evolving techniques of telecommunication fields. AI has found a broad application to exceed the efficiency of the telecommunications substructure.

Handling with Big Data

The telecommunications industry is one of the sectors that have to get over to big data. The fact that customer data is available in a mixture of various sources often poses a problem. Therefore, managing them manually will be time-consuming and will incur additional costs. Telecommunications, like all organizations in the business sector, try to maximize their revenues by reducing operating costs. With AI and ML, the handle of Big Data will be much easier. Therefore revenue will increase. B2Metric can turn your customer data into business insights and can use that information to make intelligent decisions, predict outcomes, suggest actions and automate tasks based on machine learning.
