What is the Role of Quality Assurance in Artificial Intelligence

QA engineers work hard to find problems in software and app code. However, bugs often go unnoticed and slip through the cracks.

Incorporating AI in QA automation can help reduce this issue by removing human error. It can result in faster and more accurate results.

Identifying errors

AI is a new technology that enables computers to perform sophisticated tasks. It is a tool that can improve business processes and help people live more efficiently.

Errors are among the most common sources of confusion when building and using AI products and services. Users of can perceive them in various ways, and they might have needed to be addressed appropriately by the system creators. 

Identifying errors and failures is a vital part of quality assurance, and it helps you build confidence in your AI system. It also allows you to create effective error messaging, which will positively impact how your AI interacts with users and how they perceive its value.

Another key component of responsible AI is error analysis, which provides a deeper understanding of the error distribution across a dataset and inputs. It enables you to identify cohorts of data with higher error rates than the overall benchmark, and it helps you diagnose the causes behind them.

In addition, it can help you determine how these errors affect your product’s reliability and safety, which could have a negative impact on user experience.

Detecting anomalies

Anomaly detection is a process that finds outliers in a data set, items that don’t belong. These can indicate network traffic that deviates from expected patterns, a sensor on the fritz, or data that needs cleaning before analysis.

Several machine learning algorithms are used to detect anomalies. The most common method is the local outlier factor (LOF). This algorithm compares the density of each data point to its neighboring data points, and if there’s a significant difference, it’s considered an anomaly.

Another approach is using an artificial neural network (NN). NNs can learn from unlabeled data and can detect anomalies in unstructured data sets.

Anomaly detection can be applied in many industries and sectors, including healthcare, financial services, government, sports, and entertainment. It can also automatically identify and remediate errors in large, complex data sets.

Quality assurance is critical to the success of data analysis, and identifying and addressing errors early can lead to higher profitability. QA checks can be as simple as comparing metrics against predefined thresholds to confirm that the model delivers adequate quality. They can be more detailed analyses and reviews of a data set or model.

Building quality assurance checks and balances are essential whether you’re deploying AI. Several QA steps are easy to automate; others require manual work, domain knowledge, and common sense. Adding in these steps will ensure the quality of your data and machine learning models and improve the accuracy of your results.

Identifying the root cause

AI-powered inspection solutions can help manufacturers spot errors more quickly than human inspectors. They can also identify the root cause of problems and avoid future defects, reducing manufacturing costs and improving product quality.

These systems can detect a problem in any part of the production line using machine vision and AI-driven deep learning. They can also track how the issue occurs and what parts of the value chain need changes to improve yield.

When it comes to software QA, AI can improve testing by predicting where code errors will occur and directing automated tests to fix them. It helps QA engineers spend their time on more complex testing, speeding up product delivery and freeing resources for other projects.

These tools can help companies preempt quality issues, translating to more satisfied customers and a greater customer base. They can also reduce process cycles and increase productivity, as employees can focus on core business activities.

Identifying blindspots

An important QA check is evaluating the accuracy of the algorithm’s predictions. It is done by comparing the results of a model to a predefined threshold or value. It can be done using various methods, such as cross-validation or regression analyses.

Often, these tests uncover issues that aren’t apparent at the start of the process. For example, some companies aren’t collecting enough user data or training the system on a diverse range of scenarios.

It can result in inaccurate predictions or even biased results that negatively impact users. It can also cause users to reject the algorithm’s results, causing it to be retrained.

Blindspots in AI systems can arise from several sources, such as oversights in a team’s workflow, unconscious biases, or structural inequalities, which can negatively affect an AI’s output.
