How does AI anomaly detection work?

 1. Introduction

What is anomaly detection? This term generally refers to the recognition of unusual patterns or values within a data set that deviates significantly from what is considered normal. 

In any type of industry, it is important to find these as if they are not detected in time, this can translate into a decline in production, lowering quality and results or even producing unplanned downtime that could cause serious financial losses.

However, thanks to the emergence of Industry 4.0 and AI-based anomaly detection, these situations are becoming less common. In this article, we will find out more about how technology is transforming industry operations through the usage of AI.

2. Discovering AI anomaly detection

AI anomaly detection techniques use machine learning algorithms to identify anomalous values in production data in real-time.

These technologies can analyze large volumes of information from sensors, equipment and production systems, detecting subtle changes that could indicate potential issues. In doing so, it enables companies to anticipate errors, optimize processes and enable preventive and proactive maintenance work.

2.1 How does AI anomaly detection work?

1. Capture: Modern industrial machinery is equipped with sensors that collect and accumulate data, forming complex and multidimensional data sets.
2. Tagging: this includes correctly tagged information about factors such as temperature, pressure, vibration, energy consumption and other critical parameters of the working equipment or the quality of every output.
3. Training: the richness and diversity of the data provided make for a solid basis for training AI systems, both supervised and unsupervised. This can help to identify patterns and allow for the optimal performance of processes. 
4. Predictive models: thanks to Machine Learning, statistics, probability and neural network technologies, data can be used to generate predictive models which establish a baseline for normal behavior.
5. Anomaly detection: by analyzing current data and comparing it to these predictive models, any deviation from this baseline is flagged as a potential anomaly, allowing the detection of small statistical anomalies that might go unnoticed by human operators. 
6. Action: when this happens, the system can present the anomaly detection visually in images, alerting operators or triggering automatic corrective actions.

3. The Benefits of AI Over Traditional Anomaly Detection

• Predictability: AI can predict and detect any anomalies early, allowing manufacturers to take preventive measures even before it becomes a problem.
• Increased accuracy: AI algorithms can better differentiate between normal variations and true anomalies, decreasing unnecessary alerts in the process.
• Quality issues: AI can detect subtle differences in production parameters that could negatively affect the quality of the final product. It can also make adjustments to maintain consistency within quality standards.
• Real-time analysis: AI systems can process large volumes of data in real-time, providing accurately updated information on the status of the systems.
• Resource optimization: by proactively identifying inefficiencies and potential problems, AI helps to optimize resources and reduce operational costs.
• Improved security: early anomaly detection techniques can prevent critical failures, improving worker safety and even reducing environmental risks.
• Continuous improvement: AI systems continuously learn from new data, improving their ability to detect anomalies.

 4. Applications of AI-based anomaly detection for industry

Currently, many AI anomaly detection examples are transforming industrial operations.

One of the most common ones is in predictive maintenance of industrial equipment. Unexpected anomalies in data provide information about the condition of equipment, which can indicate valuable information about the condition of the equipment or the deterioration of machine sensors. With this information, AI systems can schedule preventative maintenance interventions, avoiding unplanned breakdowns while optimizing maintenance costs.

AI anomaly detection can also be applied in quality control. For example, in CNC manufacturing processes, high-resolution images and computer vision algorithms can be used to detect imperceptible defects in manufactured parts. AI analyzes these images in real time, identifying imperfections that could be invisible to the human eye.

Another example refers to the process optimization in chemical plants. AI systems can continuously monitor variables such as temperature, pressure, and chemical concentrations in reactors. By detecting deviations in data, AI can automatically adjust process conditions, improving performance and energy efficiency.

5. Conclusion

Anomaly detection AI techniques enable engineers to design end-to-end solutions that allow knowledge and complex automated processes to go further than ever before. The impact of these technologies is transforming industry standards, improving efficiency, quality, and safety, with the proposition that any company can achieve operational excellence.
