Machine L...

A fleet is a group of systems (e.g., cars, aircraft) that are designed and manufactured the same way and are intended to be used the same way. For example, a fleet of delivery trucks may consist of one hundred instances of a particular model of truck, each of which is intended for the same type of service—almost the same amount of time and distance driven every day, approximately the same total weight carried, etc. For this reason, one may imagine that data mining for fleet monitoring may merely involve collecting operating data from the multiple systems in the fleet and developing some sort of model, such as a model of normal operation that can be used for anomaly detection. However, one then may realize that each member of the fleet will be unique in some ways—there will be minor variations in manufacturing, quality of parts, and usage. For this reason, the typical machine learning and statis- tics algorithm’s assumption that all the data are independent and identically distributed is not correct. One may realize that data from each system in the fleet must be treated as unique so that one can notice significant changes in the operation of that system.

Anomaly Detection for Data Pipelines Market Outlook

According to our latest research, the global anomaly detection for data pipelines market size stood at USD 2.41 billion in 2024, reflecting strong demand for advanced data integrity and security solutions across industries. The market is expected to grow at a robust CAGR of 19.2% from 2025 to 2033, reaching a forecasted value of USD 11.19 billion by 2033. This remarkable growth is primarily driven by the increasing complexity of data ecosystems, the proliferation of real-time analytics, and mounting concerns over data quality and security breaches worldwide.

The primary growth factor for the anomaly detection for data pipelines market is the exponential increase in data volumes and the complexity of data flows in modern enterprises. As organizations adopt multi-cloud and hybrid architectures, the number of data pipelines and the volume of data being processed have surged. This complexity makes manual monitoring infeasible, necessitating automated anomaly detection solutions that can identify irregularities in real-time. The growing reliance on data-driven decision-making, coupled with the need for continuous data quality monitoring, further propels the demand for sophisticated anomaly detection tools that can ensure the reliability and consistency of data pipelines.

Another significant driver is the rising incidence of cyber threats and fraud attempts, which has made anomaly detection an essential component of modern data infrastructure. Industries such as BFSI, healthcare, and retail are increasingly integrating anomaly detection systems to safeguard sensitive data and maintain compliance with stringent regulatory requirements. The integration of artificial intelligence and machine learning into anomaly detection solutions has enhanced their accuracy and adaptability, enabling organizations to detect subtle and evolving threats more effectively. This technological advancement is a major catalyst for the market’s sustained growth, as it enables organizations to preemptively address potential risks and minimize operational disruptions.

Furthermore, the shift towards real-time analytics and the adoption of IoT devices have amplified the need for robust anomaly detection mechanisms. Data pipelines now process vast amounts of streaming data, which must be monitored continuously to detect anomalies that could indicate system failures, data corruption, or security breaches. The ability to automate anomaly detection not only reduces the burden on IT teams but also accelerates incident response times, minimizing the impact of data-related issues. As digital transformation initiatives continue to accelerate across sectors, the demand for scalable, intelligent anomaly detection solutions is expected to escalate, driving market expansion over the forecast period.

Regionally, North America holds the largest share of the anomaly detection for data pipelines market, driven by the presence of major technology companies, early adoption of advanced analytics, and stringent regulatory frameworks. Europe follows closely, with significant investments in data security and compliance.

For the purposes of this paper, the National Airspace System (NAS) encompasses the operations of all aircraft which are subject to air traffic control procedures. The NAS is a highly complex dynamic system that is sensitive to aeronautical decision-making and risk management skills. In order to ensure a healthy system with safe flights a systematic approach to anomaly detection is very important when evaluating a given set of circumstances and for determination of the best possible course of action. Given the fact that the NAS is a vast and loosely integrated network of systems, it requires improved safety assurance capabilities to maintain an extremely low accident rate under increasingly dense operating conditions. Data mining based tools and techniques are required to support and aid operators’ (such as pilots, management, or policy makers) overall decision-making capacity. Within the NAS, the ability to analyze fleetwide aircraft data autonomously is still considered a significantly challenging task. For our purposes a fleet is defined as a group of aircraft sharing generally compatible parameter lists. Here, in this effort, we aim at developing a system level analysis scheme. In this paper we address the capability for detection of fleetwide anomalies as they occur, which itself is an important initiative toward the safety of the real-world flight operations. The flight data recorders archive millions of data points with valuable information on flights everyday. The operational parameters consist of both continuous and discrete (binary & categorical) data from several critical subsystems and numerous complex procedures. In this paper, we discuss a system level anomaly detection approach based on the theory of kernel learning to detect potential safety anomalies in a very large data base of commercial aircraft. We also demonstrate that the proposed approach uncovers some operationally significant events due to environmental, mechanical, and human factors issues in high dimensional, multivariate Flight Operations Quality Assurance (FOQA) data. We present the results of our detection algorithms on real FOQA data from a regional carrier.

Anomaly detection methods include ARIMA (AutoRegressive Integrated Moving Average) and LSTM (Long Short Term Memory). These are time series regression methods that detect anomalies by comparing model estimates to sensor observations and labeling points as anomalous when they exceed a threshold. There are multiple possible approaches for applying LSTM for anomaly detection/correction. - Vanilla LSTM: uses past values of a single variable to estimate the next value of that variable. - Multivariate Vanilla LSTM: uses past values of multiple variables to estimate the next value for all variables. - Bidirectional LSTM: uses past and future values of a single variable to estimate a value for that variable at the time step of interest. - Multivariate Bidirectional LSTM: uses past and future values of multiple variables to estimate a value for all variables at the time step of interest.

The correction approach uses piecewise ARIMA models. Each group of consecutive anomalous points is considered as a unit to be corrected. Separate ARIMA models are developed for valid points preceding and following the anomalous group. Model estimates are blended to achieve a correction.

The anomaly detection and correction workflow involves the following steps: 1. Retrieving data 2. Applying rules-based detection to screen data and apply initial corrections 3. Identifying and correcting sensor drift and calibration (if applicable) 4. Developing a model (i.e., ARIMA or LSTM) 5. Applying model to make time series predictions 6. Determining a threshold and detecting anomalies by comparing sensor observations to modeled results 7. Widening the window over which an anomaly is identified 8. Aggregating detections resulting from multiple models 9. Making corrections for anomalous events

Cloud computing is widely applied by modern software development companies. Providing digital services in a cloud environment offers both the possibility of cost-efficient usage of computation resources and the ability to dynamically scale applications on demand. Based on this flexibility, more and more complex software applications are being developed leading to increasing maintenance efforts to ensure the reliability of the entire system infrastructure. Furthermore, highly available cloud service requirements (99.999% as industry standards) are difficult to guarantee due to the complexity of modern systems and can therefore just be ensured by great effort. Due to these trends, there is an increasing demand for intelligent applications that automatically detect anomalies and provide suggestions solving or at least mitigating problems in order not to cascade a negative impact on the service quality. This thesis focuses on the detection of degraded abnormal system states in cloud environments. A holistic analysis pipeline and infrastructure is proposed, and the applicability of different machine learning strategies is discussed to provide an automated solution. Based on the underlying assumptions, a novel unsupervised anomaly detection algorithm called CABIRCH is presented and its applicability is analyzed and discussed. Since the choice of hyperparameters has a great influence on the accuracy of the algorithm, a hyperparameter selection procedure with a novel fitness function is proposed, leading to further automation of the integrated anomaly detection. The method is generalized and applicable for a variety of unsupervised anomaly detection algorithms, which will be evaluated including a comparison to recent publications. The results show the applicability for the automated detection of degraded abnormal system states and possible limitations are discussed. The results show that detection of system anomaly scenarios achieves accurate detection rates but comes with a false alarm rate of more than 1%.

Component Analysis

The Component segment of the Data Quality as a Service market is bifurcated into software and services, each playing a pivotal role in the overall ecosystem. The software component comprises platforms and tools that offer functionalities such as data cleansing, profiling, matching, and monitoring.

A fleet is a group of systems (e.g., cars, aircraft) that are designed and manufactured the same way and are intended to be used the same way. For example, a fleet of delivery trucks may consist of one hundred instances of a particular model of truck, each of which is intended for the same type of service—almost the same amount of time and distance driven every day, approximately the same total weight carried, etc. For this reason, one may imagine that data mining for fleet monitoring may merely involve collecting operating data from the multiple systems in the fleet and developing some sort of model, such as a model of normal operation that can be used for anomaly detection. However, one then may realize that each member of the fleet will be unique in some ways—there will be minor variations in manufacturing, quality of parts, and usage. For this reason, the typical machine learning and statis- tics algorithm’s assumption that all the data are independent and identically distributed is not correct. One may realize that data from each system in the fleet must be treated as unique so that one can notice significant changes in the operation of that system.
